Green Building - Sustainable Development
Green is something that is not damaging
to the environment, and also prevents environmental damage. Green is concerned with the
principles and
moral standards
of being
sustainable and
less wasteful and
less polluting. Green
is the color of life and a symbol for renewal, revitalization, rebirth,
nature, energy, and is associated with meanings of growth, vitality,
wealth, harmony, freshness, safety, fertility, and environment. Green is
everywhere and is the most common color in the natural world, and is
second only to blue as the most common favorite color. Green
can also mean a piece of
open land
for recreational use in an urban area.

Homes should not be
energy slaves, or be
rent traps,
or be a
source of pollution or a
contributor of pollution.
No one should force other people to pay for your dependencies, like drug
addicts
do. People need to be aware of the relationships that
they are getting into, especially the relationships that we
have with material things such as our homes, whose
maintenance shouldn't have to
cost more then the product itself. You are
essentially
buying debt and poison, and you are forcing
future generations to have to pay for your debt and suffer
from your poison too, which is unfair, illogical and
unjustifiable.
Buildings already account for up to 40% of our global energy demands,
which is unsustainable and criminal.
Zero Energy Building
is a
building with
zero net energy consumption, meaning the total amount
of energy used by the building on an annual basis is roughly equal to the
amount of
renewable energy created on the site.

If the things you receive, or if the
things that are provided
for you, like a home, if that gift disconnects you from
reality and the true nature of things, then that is not a gift, that is a trap.
When your home needs services that pollute or damage the
environment, then you are slowly killing yourself in a trap
that someone else has set for you. But if you had a choice
to build a better home, I'm sure you would pick a home that
was more respectable to your life as well as respectable to
other lives and to future generations, while saving you
time, people, money and resources, what a sweet deal that
is.

When you hear someone say that environmentally friendly
energy
efficient homes cost to much, what they are really saying is
that they would rather, selfishly and narrow mindedly, pass on
the
Cost and the Debt and the
Dependency on to someone else
rather then do what is right. Forcing future generations to suffer from
your ignorance is unfair and illogical and unjustifiable. These bad
decisions takes away future generations choice of freedom and
sustainability. This criminal and ignorant activity needs to stop. "Do it
Right the First Time" needs to be the slogan of all developers.
According to the Idaho Forest
Products Commission,
a typical 2000 square foot house requires 26,700 board feet.
An "average" tree with a 20 inch diameter and 42 linear feet of
usable wood generates approximately 260 board feet.
Doing the math indicates about 102
trees for that house.
Other organizations in the lumber industry state different
numbers, some as low as 30 trees for a 1500 square foot
house while some state 60 trees for a 2000 square foot house. So
if everyone who uses trees to build houses plants enough trees
to build 2 houses we can slow down the
deforestation.

Warning: Green
Certified is a
vague phrase,
because everything is
relative,
which means that many questions need to be answered. Is the process
greener than the other alternative that this particular process was
compared to? Who measured these comparisons? Are the comparisons verified
by a third party? Is this certification only applicable to only a few
unique scenarios? All labels need an explanation because there is just too
much
false advertising.
Leadership in Energy and Environmental Design is a
green building
certification program used worldwide. Developed by the non-profit U.S.
Green Building Council or USGBC, it includes a set of rating systems
for the design,
construction, operation, and maintenance of green buildings, homes,
and neighborhoods which aims to help building owners and operators be
environmentally responsible and use resources efficiently. The goal of all
certification rating systems is to provide tools and methods to assess the
environmental and resource-efficient performance of a building. The main
objectives of such tools are: Optimize building performance and minimize
environmental impacts. Provide a way to quantify a building’s
environmental effects. Set standards and benchmarks to assess buildings
objectively. Furthermore, the end result of such an assessment is to
provide a certificate verifying the achievement of the desired performance
and quality of the building. Some benefits of certifying a building or a
property include: The negative impacts of a building on the environment
can be better understood and this knowledge can be utilized to reduce such
impacts. Holistic sustainability considerations will be made for the
fulfillment of technical, economic, social and functional requirements of
the building. Promotes sustainable design and construction principles
throughout the building lifecycle. Increases the monetary value of a
building or a property in the real estate market.

Independence is a condition of a nation, country, or state
in which its residents and population, or some portion thereof,
exercise
self-government, and
usually sovereignty, over the territory. The opposite of
independence is a dependent territory.
Independence does not
necessarily mean
freedom.
Self-Reliance the need for each individual to avoid

any authority which they cannot themselves alter.
Open Governance.
Self
Sustainability is a
system
that is
self-sustaining or
self-sufficient that can
maintain itself
by independent effort. The system self-sustainability is the degree at
which the system can sustain itself without external support, the fraction
of time in which the system is self-sustaining. Self-sustainability is
considered one of the "ilities" and is closely related to sustainability
and availability.
Self
Perpetuating is to cause to continue or prevail. Causing
itself to continue to exist.
Self-Sufficiency is the state of not requiring any aid,
support, or interaction, for survival; it is therefore a type of personal
or collective autonomy. On a national scale, a totally self-sufficient
economy that does not trade with the outside world is called an autarky.

Self-Managed Economy is based on collaborative self-management,
common
ownership of resources, and the production of use-values through the free
cooperation of producers who have access to distributed capital.
Self-Care is any

Individualism is the moral stance that emphasizes the moral worth of the
individual. Individualists promote the exercise of one's goals and desires
and so value independence and self-reliance and advocate that interests of
the
individual should
achieve
precedence over the state or a social group, while opposing
external interference upon one's own interests by society or institutions
such as the government. Individualism is often defined in contrast to
totalitarianism, collectivism and more corporate social forms. Avoiding

Individual Discretion is the power or the
right to decide or act according to one's

Methodological Individualism is the requirement that causal accounts
of social phenomena explain how they result from the motivations and
actions of individual agents, at least in principle.
We are One Species. This is not to say that
you don't have
individuality or
autonomy, because you do. It's just saying
that you are not just one person, or that you're
alone, because you're not.
Don't separate everything that you are from
everything that we are.
No one is anyone without anyone else.
We are one. And you or I
are just parts of us. And most everyone is good parts, except for some of
the bad parts, who are not
part of us, they're just parts that we don't need, unless we can educate
them.
Agency in
sociology is the
capacity of individuals to act
independently
and to make their own free
choices. By contrast, structure is those
factors of influence (such as social class, religion, gender, ethnicity,
ability, customs, etc.) that determine or limit an agent and his or her
decisions. The relative difference in influences from structure and
agency
is debated – it is unclear to what extent a person's actions are
constrained by social systems. One's agency is one's independent
capability or ability to act on one's
will. This ability is affected by
the cognitive belief structure which one has formed through one's
experiences, and the
perceptions held by the society and the individual,
of the structures and circumstances of the environment one is in and the
position they are born into. Disagreement on the extent of one's agency
often causes conflict between parties, e.g. parents and children.
Intelligent Agent.
Agency in
philosophy is the
capacity
of an actor to
act in a given
environment. The capacity to act
does not at first imply a specific
moral dimension to the ability to make the
choice to
act, and moral agency is therefore a
distinct concept. In sociology, an agent is an individual engaging with
the social structure. The level of reflexivity an agent may possess may
either be classified as
unconscious,
involuntary behavior, or
purposeful,
goal directed activity (intentional
action). An agent typically has some sort of immediate awareness of their
physical activity and the goals that the activity is aimed at realizing.
In ‘goal directed action’ an agent implements a kind of direct
control
or
guidance
over their own
behavior.
Sense of Agency or
sense of control, is the subjective awareness of
initiating,
executing, and controlling one's own volitional actions in the
world. It is the pre-reflective awareness or implicit sense that it is I
who is executing
bodily movement(s) or
thinking thoughts. In normal,
non-pathological experience, the SA is tightly integrated with one's
"sense of ownership" (SO), which is the pre-reflective awareness or
implicit sense that one is the owner of an action, movement or thought. If
someone else were to move your arm (while you remained
passive) you would
certainly have sensed that it were your arm that moved and thus a sense of
ownership (SO) for that movement. However, you would not have felt that
you were the author of the movement; you would not have a sense of agency
(SA).
Structure and Agency is the ability of an individual to
organize future situations
and resource distribution.
Structure is the
recurrent patterned arrangements which influence or limit the choices and
opportunities available. Agency is the capacity of individuals to act
independently and to make their own free choices. The structure versus
agency debate may be understood as an issue of socialization against
autonomy in determining whether an individual acts as a free agent or in a
manner dictated by social structure.
Emotional Self-Regulation is the ability to respond to the ongoing
demands of experience with the range of
emotions in a manner that is
socially tolerable and sufficiently flexible to permit spontaneous
reactions as well as the ability to delay spontaneous reactions as needed.
It can also be defined as
extrinsic and
intrinsic
processes responsible for monitoring,
evaluating, and modifying emotional reactions. Emotion self-regulation
belongs to the broader set of emotion-regulation processes, which includes
the regulation of one's own feelings and the regulation of other people's
feelings. Emotional regulation is a complex process that involves
initiating, inhibiting, or
modulating one's state or behavior in a given situation – for example
the subjective experience (feelings), cognitive responses (thoughts),
emotion-related physiological responses (for example heart rate or
hormonal activity), and emotion-related behavior (bodily actions or
expressions). Functionally, emotional regulation can also refer to
processes such as the tendency to focus one's attention to a task and the
ability to suppress inappropriate behavior under instruction. Emotional
regulation is a highly significant function in human life. Every day,
people are continually exposed to a wide variety of potentially arousing
stimuli. Inappropriate, extreme or unchecked emotional reactions to such
stimuli could impede functional fit within society; therefore, people must
engage in some form of emotion regulation almost all of the time.
Generally speaking, emotional dysregulation has been defined as
difficulties in
controlling
the
influence of emotional
arousal on the organization and quality of thoughts, actions, and
interactions. Individuals who are emotionally dysregulated exhibit
patterns of responding in which there is a mismatch between their goals,
responses, and/or modes of expression, and the demands of the social
environment. For example, there is a significant association between
emotion dysregulation and symptoms of depression, anxiety, eating
pathology, and substance abuse. Higher levels of emotion regulation are
likely to be related to both high levels of
social competence and the expression
of socially appropriate emotions.
Self-Monitoring
refers to an ability to regulate behavior to accommodate social
situations, and to closely monitor your audience in order to ensure
appropriate or desired public appearances. It's understanding how
individuals and groups will perceive your actions.
Empathy (seeing
yourself from someone else's point of view).
Self-Regulatory Organization is an organization that exercises some
degree of
regulatory authority over an
industry or profession. The regulatory authority could exist in place of
government regulation, or applied in addition to government regulation.
The ability of an SRO to exercise regulatory authority does not
necessarily derive from a grant of authority from the government.
Natural and Legal Rights are two types of rights.
Legal Rights are those bestowed onto a
person by a given legal system (i.e., rights that can be
modified, repealed, and restrained by human laws).
Natural Rights are those that are
not dependent on the laws, customs, or beliefs of any particular
culture or government, and therefore universal and inalienable
(i.e., rights that cannot be repealed or restrained by human
laws).
System Quality Attributes within systems engineering, quality
attributes are realized non-functional requirements used to evaluate the
performance of a system. These are sometimes named "ilities" after the
suffix many of the words share. They are usually Architecturally
Significant Requirements that require architects' attention.
Industry
Self Regulation is when an
organization monitors its own adherence to
legal, ethical, or safety standards, rather than have an outside,
independent agency such as a third party entity monitor and enforce those
standards.
Self-Policing
Self-Organization
is an organization that is decentralized or distributed over all the
components of the system. As such, the organization is typically robust
and able to survive and, even, self-repair substantial damage or
perturbations.
Sovereign Citizen Movement is when self-described sovereign citizens
take the position that they are answerable only to their particular
interpretation of the common law and are not subject to any government
statutes or proceedings. They do not recognize United States currency,
and maintain that they are "free of any legal constraints." They
especially reject most forms of taxation as illegitimate. Participants in
the movement argue this concept in opposition to "federal citizens," who,
they say, have unknowingly forfeited their rights by accepting some aspect
of federal law. The doctrines of the movement are similar to those of the
freemen on the land movement more commonly found in Britain and Canada.
Etienne de La Boetie.
Feedback occurs when outputs of a system are routed back as inputs as
part of a chain of
cause-and-effect that forms a circuit or loop. The
system can then be said to feed back into itself. The notion of
cause-and-effect has to be handled carefully when applied to feedback
systems. Is Feedback another word for
Learning? But you still have to define what you're learning.
Survival Skills
are techniques that a person may use in order to
sustain life in any type
of environment. These techniques are meant to provide
basic necessities
for human life which include water, food, and shelter. The skills also
support proper knowledge and interactions with animals and plants to
promote the sustaining of life over a period of time. Survival skills are
often basic ideas and abilities that ancients invented and used themselves
for thousands of years. Outdoor activities such as hiking, backpacking,
horseback riding, fishing, and hunting all require
basic wilderness survival skills, especially in handling
emergency
situations.
Bushcraft and primitive living are most often self-implemented, but
require many of the same skills.
Interdependence is the
mutual reliance between two or more
groups. In relationships, interdependence is the degree to which
members of the group are mutually dependent on the others. This
concept differs from a dependent relationship, where some
members are dependent and some are not. Independencies is
freedom from control or influence of
another or others.
Personal Development covers activities that improve awareness and
identity, develop talents and potential, build human capital and
facilitate employability, enhance quality of life and contribute to the
realization of dreams and aspirations.
Workers Self-Management is a form of
organizational
management based on self-directed work processes on the part of an
organization's workforce.

Holacracy is a
system of organizational governance in which
authority and decision-making are distributed throughout a holarchy of
self-organizing teams rather than being vested in a
management hierarchy.
Sociocracy is a
system of governance using consent decision
making and an organizational structure based on cybernetic principles (a
system with closed feedback mechanisms). Sociocracy has
been advocated as a management system that distributes leadership and
power throughout the organization. It is currently used by public,
private, non-profit, and community organizations and associations.
Sociocratic governance and management is taught in college and university
courses in business, political science, history, and sociology.
Polis is the Ancient
Greek
city-state developed during the
Archaic period, considered in its ideal form for philosophical purposes.
The best form of government of the polis for Plato is the one that
leads to the common good.
The
philosopher king is the
best ruler because, as a philosopher, he is acquainted with the Form of
the Good. In Plato's analogy of the ship of state, the philosopher king
steers the polis, as if it were a ship, in the best direction. The basic
and indicating elements of a polis are
Self-governance, autonomy, and independence (city-state).

Development Humanity is a concept within a field of
international development. It involves studies of the human condition with
its core being the capability approach. The inequality adjusted Human
Development Index is used as a way of measuring actual progress in human
development by the United Nations. It is an alternative approach to a
single focus on economic growth, and focused more on social justice, as a
way of understanding progress
Livelihood refers to their "
means of securing the basic
necessities -food, water, shelter and clothing- of life". Livelihood is
defined as a set of activities, involving securing water, food, fodder,
medicine, shelter, clothing and the capacity to acquire above necessities
working either individually or as a group by using endowments (both human
and material) for meeting the requirements of the self and his/her
household on a sustainable basis with dignity. The activities are usually
carried out repeatedly.
Subsistence Economy is a non-monetary economy which relies
on natural resources to provide for basic needs, through hunting,
gathering, and subsistence agriculture.
Subsistence means supporting
oneself at a minimum level; in a subsistence economy, economic surplus is
minimal and only used to trade for basic goods, and there is no
industrialization.
Subsistence Agriculture is self-sufficiency farming in which
the farmers focus on
growing
enough food to feed themselves and their families. The output is
mostly for local requirements with little or no surplus for trade. The
typical subsistence farm has a range of crops and animals needed by the
family to feed and clothe themselves during the year.

guides your
planned actions.
Independent, not Dependent: You don't want people to be dependent or
Codependent, you want people to be independent, free to
choose, free to explore, free to learn. Yes we will always have
people who will need help and will have to be
Dependent on other people to live, but it will not be
because they're ignorant, it will be because they have no choice because
of a disability, or because of where they live, where they can't fulfill
all their needs because of the land or that they live in city with few
options. This is why you have to be intelligent when building your cities.
Just look at history. You find these ancient cities that have been
abandoned, why? Independency can only come from knowledge, so education
needs to improve.
Interdependence is the mutual reliance between two or more
groups. This concept differs from the reliance in a dependent
relationship, where some members are dependent and some are not. There can
be various degrees of interdependence.

"A lot of people live in their own little world because they don't have
the right information and knowledge to see beyond the bubble
that they live in, thus they are vulnerable to threats and are
unable to respond accordingly to these threats. Threats that
come from the environment and from other people."
"In order for humans to enjoy the freedoms of being human in the
physical world, and function with freedom of choice, humans must learn to
do certain life preserving functions 'manually'. This is just a small
inconvenience for freedom. We are still in control but we are also

"I see an incredible future for this planet and all its species,
that's if information and knowledge is properly shared.
Humans have incredible abilities, as you can see from our
technological advances. And one of our most incredible abilities,
is our ability to communicate, which could reverse the damage we
have done to ourselves and the planet. But as it is right now our communication system is dysfunctional
and corrupted. If we don't fix this we will continue to decimate this planet
and all of its species to the point of mass extinction. And even
if some of us do manage to survive it will be in a world that is
horribly unlivable.
Communicating information and knowledge that people desperately
need has to be top priority. I know this will work because we have documented proof that it
does work. Any place where you have a more informed and educated
people is a place of prosperity. Not to say that this process will be without problems or
difficulties, but as long as it's done right and keeps going, it
will fix these problems and difficulties that we will face along the way."
Stateless Society is a society that is not
governed by a
state. In stateless
societies, there is little concentration of authority; most positions of
authority that do exist are very limited in power and are generally not
permanently held positions; and social bodies that resolve disputes
through predefined rules tend to be small. Stateless societies are highly
variable in economic organization and cultural practices. While stateless
societies were the norm in human prehistory, few stateless societies exist
today; almost the entire global population resides within the jurisdiction
of a
sovereign state. In some regions nominal
state authorities may be very weak and wield little or no actual power.
Over the course of history most stateless peoples have been integrated
into the state-based societies around them. Some political philosophies,
particularly anarchism, consider the state an unwelcome institution and
stateless societies the ideal.
State of Nature in moral and political philosophy, religion, social
contract theories and international law, is the hypothetical
life of people before societies came into
existence. Philosophers of the
state of nature theory
deduce that there must have been a time before organized societies
existed, and this presumption thus raises questions such as: "What was
life like before civil society?"; "How did
government first emerge
from such a starting position?," and; "What are the hypothetical reasons
for entering a state of society by establishing a nation-state?". In some
versions of social contract theory, there are no rights in the state of
nature, only freedoms, and it is the contract that creates rights and
obligations. In other versions the opposite occurs: the contract imposes
restrictions upon individuals that curtail their natural rights. Societies
existing before or without a political state are currently studied in such
fields as paleolithic history, and the anthropological subfields of
archaeology, cultural anthropology, social anthropology, and ethnology,
which investigate the social and power-related structures of indigenous
and uncontacted peoples. Though this has been criticized as an
essentialist view and othering like with the concept of the noble savage.
Smart Homes - Intelligent Automation
Home Automation is the residential extension of building
automation and involves the control and automation of lighting, heating
(such as
smart
thermostats), ventilation, air conditioning (HVAC), and
security, as
well as home
appliances such as washer/dryers, ovens or
refrigerators/freezers that use WiFi for
remote monitoring. Modern systems
generally consist of switches and
sensors connected to a central hub
sometimes called a "gateway" from which the system is controlled with a
user
interface that is interacted either with a wall-mounted terminal,
mobile phone software, tablet computer or a web
interface, often but not
always via internet cloud services. All devices and
sensors should be
connected and easy to
monitor and adjust from an interface control panel
on any computer. And information should be displayed in any format that's
needed so that a person can quickly see changes and understand what's
happening and react accordingly. Appliances should shut off automatically
using a timer or when things boil over or when there is too much smoke.
Water should shut of automatically when leaks are detected or when
water is running too long.

Category 6 Cable is a standardized twisted pair cable for Ethernet and
other network physical layers that is backward compatible with the
Category 5/5e and Category 3 cable standards. Compared with
Cat 5 and Cat 5e, Cat 6 features more
stringent specifications for crosstalk and system noise. The cable
standard also specifies performance of up to 250 MHz compared to 100 MHz
for Cat 5 and Cat 5e.
Coaxial Cable is a type of electrical cable that has an inner
conductor surrounded by a tubular insulating layer, surrounded by a
tubular conducting shield. Many coaxial cables also have an insulating
outer sheath or jacket. The term coaxial comes from the inner conductor
and the outer shield sharing a geometric axis.
Electronic Noise
Fiber Optics are significantly faster than coaxial cables. Although
optical fibers are hair-thin, they have the capacity for greater bandwidth
than traditional cables.
Siamese Cable
stands for a cable that is built to include both video and power. In
contrast to Power over Ethernet (PoE), the power is attached to the side
of the data cable.

Conductive Paint Transforms Walls Into Sensors, Interactive Surfaces.
Smart walls react to human touch, sense activity in room. With a few
applications of conductive paint and some electronics, however, walls can
become smart infrastructure that sense human touch, and detect things like
gestures and when appliances are used. Researchers found that they could
transform dumb walls into smart walls at relatively low cost using
simple tools and techniques, such as a paint roller.
"Whether it's a Smart Home or

Green Building Resources
Green Building refers to both a structure and the
using of processes that are
environmentally responsible and
resource-efficient throughout a building's life-cycle: from siting to
design, construction, operation, maintenance,
renovation, and
demolition. In other words, green building design involves finding the
balance between homebuilding and the
sustainable environment. This
requires close cooperation of the design team, the architects, the
engineers, and the client at all project stages. The Green Building
practice expands and complements the classical building design concerns of
economy, utility, durability, and comfort.

Development Planning
Self-Sufficient Homes is a building designed to be operated
independently from infrastructural support services such as the electric
power grid, gas grid, municipal water systems, sewage treatment systems,
storm drains, communication services, and in some cases, public roads.
Advocates of autonomous building describe advantages that include reduced
environmental impacts, increased security, and lower costs of ownership.
Some cited advantages satisfy tenets of green building, not independence
per se (see below). Off-grid buildings often rely very little on civil
services and are therefore safer and more comfortable during civil
disaster or military attacks. (Off-grid buildings would not lose power or
water if public supplies were compromised for some reason.)
Zero Energy Building is a building with
zero net energy
consumption, meaning the total amount of energy used by the building on an
annual basis is roughly equal to the amount of renewable energy created on
the site, or in other definitions by renewable energy sources elsewhere.
These buildings consequently contribute less overall greenhouse gas to the
atmosphere than similar non-ZNE buildings. They do at times consume
non-renewable energy and produce greenhouse gases, but at other times
reduce energy consumption and greenhouse gas production elsewhere by the
same amount.
Energy Plus House produces more energy from renewable
energy sources, over the course of a year, than it imports from external
sources. This is achieved using a combination of
microgeneration technology and
low-energy building techniques, such as:
passive solar building design, insulation and careful site selection
and placement. A reduction of modern conveniences can also contribute to
energy savings, however many energy-plus houses are almost
indistinguishable from a traditional home, preferring instead to use
highly energy-efficient appliances, fixtures, etc., throughout the house.
Plus Energy is a term used in building design to describe a structure
that
produces more energy than it uses. The
term was coined in 1994 by Rolf Disch when building his private residence,
the Heliotrope as the first PlusEnergy house in the world. Disch then went
on to refine the concepts involved with several more projects built by his
company Rolf Disch Solar Architecture in order to promote PlusEnergy for
wider adoption in residential, commercial and retail spaces. Disch
maintains that PlusEnergy is more than just a method of producing
environmentally-friendly housing, but also an integrated ecological and
architectural concept. As such, PlusEnergy is intended to be superior to
low-energy or zero-energy designs such as those of
Passivhaus, which is a rigorous, voluntary standard for energy
efficiency in a building, reducing its ecological footprint. It results in
ultra-low energy buildings that require little energy for space heating or
cooling.
Passive Cooling and Heating.
Environmental Technology is the application of one or more
of environmental science, green chemistry, environmental monitoring and
electronic devices to monitor, model and conserve the natural environment
and resources, and to curb the negative impacts of human involvement. The
term is also used to describe sustainable energy generation technologies
such as
photovoltaics,
wind turbines,
bioreactors, etc.
Sustainable development is the core of
environmental technologies. The term environmental technologies is also
used to describe a class of electronic devices that can promote
sustainable management of resources.
Living Building Challenge is an international sustainable
building certification program created in 2006 by the non-profit
International Living Future Institute.
Solar Decathlon
is a collegiate competition made up of 10 contests that challenge student
teams to design and build full-size, solar-powered houses. The winner of
the competition is the team that best blends design excellence and smart
energy production with innovation, market potential, and energy and water
efficiency. Simply put, there's nothing else like it.
Sustainable Building Competition – 4th Edition
Natural Building
involves a range of building systems and materials that place
major emphasis on sustainability. Ways of achieving sustainability through
natural building focus on durability and the use of minimally processed,
plentiful or renewable resources, as well as those that, while recycled or
salvaged, produce healthy living environments and maintain indoor air
quality. Natural building tends to rely on human labor, more than
technology. As Michael G. Smith observes, it depends on "local ecology,
geology and climate; on the character of the particular building site, and
on the needs and personalities of the builders and users." The basis of
natural building is the need to lessen the environmental impact of
buildings and other supporting systems, without sacrificing comfort or
health. To be more sustainable, natural building uses primarily abundantly
available, renewable, reused or recycled materials. The use of rapidly
renewable materials is increasingly a focus. In addition to relying on
natural building materials, the emphasis on the architectural design is
heightened. The orientation of a building, the utilization of local
climate and site conditions, the emphasis on natural ventilation through
design, fundamentally lessen operational costs and positively impact the
environmental. Building compactly and minimizing the ecological footprint
is common, as are on-site handling of energy acquisition, on-site water
capture, alternate sewage treatment and water reuse.
Building Material is any material which is used for
construction purposes. Many naturally occurring substances, such as clay,
rocks, sand, and wood, even twigs and leaves, have been used to construct
buildings. Apart from naturally occurring materials, many man-made
products are in use, some more and some less synthetic. The manufacture of
building materials is an established industry in many countries and the
use of these materials is typically segmented into specific specialty
trades, such as carpentry, insulation, plumbing, and roofing work. They
provide the make-up of habitats and structures including homes.
Biocidal Natural Building Material is a natural building
material which has biocidal properties. The biocidal properties of
biocidal natural building materials are inherent to the material, rather
than being supplemented afterwards. This makes that the material is long
lasting and inexpensive, as no additional processing needs to be done.
Biocide
is a
chemical substance or
microorganism intended to destroy, deter, render harmless, or exert a
controlling effect on any harmful organism by chemical or biological
means.
Sick Building Syndrome is a phenomenon affecting building
occupants who claim to experience acute health and comfort effects that
appear to be linked to time spent in a building, but where no specific
illness or cause can be identified.
Living Building Challenge is an international sustainable
building certification program created in 2006 by the non-profit
International Living Future Institute. It is described by the Institute as
a philosophy, advocacy tool and certification program that promotes the
most advanced measurement of sustainability in the built environment. It
can be applied to development at all scales, from buildings – both new
construction and renovation - to infrastructure, landscapes, neighborhoods
and communities and is more rigorous than green certification schemes such
as LEED or BREEAM.

Quasicrystalline is a structure that is ordered but not
periodic. A quasicrystalline pattern can continuously fill all available
space, but it lacks translational symmetry. While crystals, according to
the classical crystallographic restriction theorem, can possess only two,
three, four, and six-fold rotational symmetries, the Bragg diffraction
pattern of quasicrystals shows sharp peaks with other symmetry orders, for
instance five-fold.
Building Homes using Dirt and Earth
Adobe is a building material made from earth and often
organic material. Most adobe buildings are similar to cob and rammed earth
buildings. Adobe is among the earliest building materials, and is used
throughout the world.
Skyscraper of Mud
Cob Material is a natural building material made from
subsoil, water, some kind of fibrous organic material (typically straw),
and sometimes lime. The contents of subsoil naturally vary, and if it does
not contain the right mixture it can be modified with sand or clay. Cob is
fireproof, resistant to seismic activity, and inexpensive. It can be used
to create artistic, sculptural forms, and its use has been revived in
recent years by the natural building and sustainability movements.

Earthen Floor also called an adobe floor, is a floor made of dirt, raw
earth, or other unworked ground materials. It is usually constructed, in
modern times, with a mixture of sand, finely chopped straw and clay, mixed
to a thickened consistency and spread with a trowel on a sub-surface such
as concrete. Once dry, it is then usually saturated with several
treatments of a drying oil.

Earth Block also known as a pressed earth block or a
compressed soil block, is a building material made primarily from damp
soil compressed at high pressure to form blocks. Compressed earth blocks
use a mechanical press to form blocks out of an appropriate mix of fairly
dry inorganic subsoil, non-expansive clay and
aggregate. If the blocks are
stabilized with a chemical binder such as Portland cement they are called
compressed stabilized earth block (CSEB) or stabilized earth block (SEB).
Typically, around 3,000 psi (21 MPa) is applied in compression, and the
original soil volume is reduced by about half.
Mudbrick
is a brick, made of a mixture of loam, mud, sand and water mixed with a
binding material such as rice husks or straw. In warm regions with very
little timber available to fuel a kiln, bricks were generally sun dried.
In some cases brickmakers extended the life of mud bricks by putting fired
bricks on top or covering them with stucco.

Angle of Repose.
Molecular Bond.
Angle of Repose of a granular material is the steepest angle of
descent or dip relative to the horizontal plane to which a material can be
piled without slumping. At this angle, the material on the slope face is
on the verge of sliding. The angle of repose can range from 0° to 90°. The
morphology of the material affects the angle of repose; smooth, rounded
sand grains cannot be piled as steeply as can rough, interlocking sands.
The angle of repose can also be affected by additions of solvents. If a
small amount of water is able to bridge the gaps between particles,
electrostatic attraction of the water to mineral surfaces will increase
the angle of repose, and related quantities such as the soil strength.
When bulk granular materials are poured onto a horizontal surface, a
conical pile will form. The internal angle between the surface of the pile
and the horizontal surface is known as the angle of repose and is related
to the density, surface area and shapes of the particles, and the
coefficient of friction of the material. Material with a low angle of
repose forms flatter piles than material with a high angle of repose. The
term has a related usage in mechanics, where it refers to the maximum
angle at which an object can rest on an inclined plane without sliding
down. This angle is equal to the arctangent of the coefficient of static
friction μs between the surfaces.
Confining pressure, Overburden Pressure, also called lithostatic pressure, confining pressure or vertical stress, is the
pressure or stress imposed on a layer of soil or rock by the weight of
overlying material.

Mechanically Stabilized Earth is soil constructed with
artificial reinforcing. It can be used for retaining walls, bridge
abutments, seawalls, and dikes. Although the basic principles of MSE have
been used throughout history, MSE was developed in its current form in the
1960s. The reinforcing elements used can vary but include steel and
geosynthetics. MSE is the term usually used in the USA to distinguish it
from the name "Reinforced Earth", a trade name of the Reinforced Earth
Company, but elsewhere Reinforced Soil is the generally accepted term.

Cement - Concrete
Cement is a
binder, a substance used in construction that
sets and hardens and can bind other materials together. The most important
types of cement are used as a component in the production of
mortar in
masonry, and of concrete, which is a combination of cement and an
aggregate to form a
strong building material. Cement is a powdery
substance made with calcined lime and clay. It is mixed with water to form
mortar or mixed with sand, gravel, and water to make concrete.
4 Billion Tons of concrete are made each year in the world.

Engineers have known for
some time that
calcium chloride salt, commonly used as deicer, reacts with
the calcium hydroxide in
concrete to form a chemical byproduct that causes
roadways to crumble. In the lab of Drexel University assistant
professor Yaghoob Farnam, researchers are using recycled materials, like
slag, silica fume and fly ash to make concrete that can withstand the
chemical deterioration caused by concrete's reaction with road salt.

A bio-inspired addition to concrete stops the damage caused by freezing
and thawing. Concrete is one of the most abundant and durable building
materials used in modern-day infrastructures, but it has a weakness --
ice -- which can cause it to crumble and
spall. Now, inspired by organisms that survive in sub-zero environments,
researchers in Colorado are introducing polymer molecules with
anti-freezing abilities into concrete. The method, which tests if the new
concrete can stop the damage caused by freezing and thawing. Concrete is a
porous material with
capillary pores that allow water to
permeate into the material. For places that experience large temperature
swings, concrete roads and buildings go through "freeze-thaw cycles." The
water freezes and expands inside of the material, building up pressure as
the ice crystals grow, eventually popping the surface of the concrete off.
The polyethylene glycol-graft-polyvinyl alcohol (PEG-PVA) molecules that
the researchers have identified appear to keep the ice crystals small and
prevent them from coalescing into larger crystals.
Roman engineers made
Roman Concrete by mixing volcanic ash with lime and seawater to make a
mortar, and then added chunks of volcanic rock. The combination of ash,
water, and lime produces what is called a
pozzolanic reaction, named after the city of Pozzuoli in the Bay of
Naples, triggering the formation of crystals in the gaps of the mixture as
it sets. When saltwater mixes with the volcanic ash and lime used by Roman
builders, it leads to the growth of interlocking minerals, which bring a
virtually impenetrable cohesion to concrete. The same reaction happens in
nature, and clumps of
natural
cement called ‘
Tuffs’
can be found scattered around volcanic areas, which is probably what gave
the Romans the idea. In contrast most modern concrete is a mix of Portland
cement - limestone, sandstone, ash, chalk, iron, and clay, among other
ingredients, heated to form a glassy material that is finely ground -
mixed with sand or crushed stone that are not intended to chemically
react, and so do not cause mineralisation when mixed with saltwater.
Binder as a material is any material or substance that holds or draws
other materials together to form a
cohesive whole mechanically,
chemically, or as an
adhesive,
which is any substance applied to one surface, or both surfaces, of two
separate items that binds them together and resists their separation.
Cohesion is the state of
cohering or sticking
together. Cohesion in physics is the intermolecular force that holds
together the molecules in a solid or liquid.
Composite Material is a material made from two or more constituent
materials with significantly different physical or chemical properties
that, when combined, produce a material with characteristics different
from the individual components.
Construction Aggregate is a broad category of coarse to medium grained
particulate material used in construction, including
sand, gravel,
crushed stone, slag,
recycled concrete and geosynthetic aggregates. Aggregates are the most
mined materials in the world. Aggregates are a component of composite
materials such as concrete and asphalt concrete; the aggregate serves as
reinforcement to add strength to the overall composite material. Due to
the relatively high hydraulic conductivity value as compared to most
soils, aggregates are widely used in drainage applications such as
foundation and French drains, septic drain fields, retaining wall drains,
and road side edge drains. Aggregates are also used as base material under
foundations, roads, and railroads. In other words, aggregates are used as
a stable foundation or road/rail base with predictable, uniform properties
(e.g. to help prevent differential settling under the road or building),
or as a low-cost extender that binds with more expensive cement or
asphalt to form concrete.
Aggregate as a composite is the component of a composite material that
resists compressive stress and provides bulk to the composite material.
For efficient filling, aggregate should be much smaller than the finished
item, but have a wide variety of sizes. For example, the particles of
stone used to make concrete typically include both sand and gravel.
Photocatalysis is the acceleration of a photoreaction in the presence
of a catalyst. In catalysed photolysis, light is absorbed by an adsorbed
substrate.
Concrete is a
composite material composed of coarse aggregate bonded together with a
fluid cement that hardens over time. Most concretes used are lime-based
concretes such as
Portland cement concrete or concretes made with other hydraulic
cements, such as
ciment fondu. However,
asphalt concrete, which is frequently used for road surfaces, is also
a type of concrete, where the cement material is bitumen, and
polymer concretes are sometimes used where the cementing material is a
polymer.
Recycled Tires create Stronger Concrete. Lab tests showed that fibre-reinforced
concrete reduces crack formation by more than 90 per cent compared to
regular concrete,
Recycled-rubber roads are not
new; asphalt roads that incorporate rubber “crumbs” from shredded
tires exist in the U.S., Germany, Spain, Brazil and China. Most scrap
tires are destined for
landfill.

Mortar in masonry is a workable paste used to bind
building blocks such
as stones, bricks, and concrete
masonry units together, fill and seal the
irregular gaps between them, and sometimes add decorative colors or
patterns in masonry walls. In its broadest sense mortar includes pitch,
asphalt, and soft mud or clay, such as used between
mud bricks.
Lime
Mortar is a type of
mortar composed of lime and an aggregate such as
sand, mixed with water. It is one of the oldest known types of mortar,
dating back to the 4th century BC and widely used in Ancient Rome and
Greece, when it largely replaced the clay and gypsum mortars common to
Ancient Egyptian construction. About 6,000 years ago, they used lime to
plaster the pyramids at Giza. In addition, the Egyptians also incorporated
various limes into their religious temples as well as their homes. Indian
traditional structures built with lime mortar, which are more than 4,000
years old like Mohenjo-daro is still a heritage monument of Indus valley
civilization in Pakistan. It is one of the oldest known types of mortar
also used in ancient Rome and Greece, when it largely replaced the clay
and gypsum mortars common to ancient Egyptian construction. With the
introduction of Portland cement during the 19th century, the use of lime
mortar in new constructions gradually declined. This was largely due to
the ease of use of Portland cement, its quick setting, and high
compressive strength. However, the soft and porous properties of lime
mortar provide certain advantages when working with softer building
materials such as natural stone and terracotta. For this reason, while
Portland cement continues to be commonly used in new constructions of
brick and concrete construction, in the repair and restoration of brick
and stone-built structures originally built using lime mortar, the use of
Portland cement is not recommended. Despite its enduring utility over many
centuries, lime mortar's effectiveness as a building material has not been
well understood; time-honoured practices were based on tradition, folklore
and trade knowledge, vindicated by the vast number of old buildings that
remain standing. Only during the last few decades has empirical testing
provided a scientific understanding of its remarkable durability.
Hydraulic Lime is a general term for varieties of lime (calcium
oxide), or slaked lime (calcium hydroxide), used to make lime mortar which
set through hydration. These contrast with varieties of air lime, the
other common types of lime mortar, which set through carbonation
(
re-absorbing carbon dioxide (CO2) from the air). Hydraulic lime provides
a faster initial set and higher compressive strength than air lime and
eminently hydraulic lime will set in more extreme conditions including
under water. The terms hydraulic lime and hydrated lime are quite similar
and may be confused but are not necessarily the same material: hydrated
lime is any lime which has been slaked whether it sets through hydration,
carbonation, or both. Calcium reacts in the lime kiln with the clay
minerals to produce silicates that enable some of the lime to set through
hydration; any unreacted calcium is slaked to calcium hydroxide which sets
through carbonation: These are sometimes called semi-hydraulic lime and
include the classifications feebly and moderately hydraulic lime, NHL 2
and NHL 3.5.
Pozzolan are a broad class of siliceous or siliceous and
aluminous materials which, in themselves, possess little or no
cementitious value but which will, in finely divided form and in the
presence of water, react chemically with calcium hydroxide at ordinary
temperature to form compounds possessing cementitious properties. The
quantification of the capacity of a pozzolan to react with calcium
hydroxide and water is given by measuring its pozzolanic activity.
Pozzolana are naturally-occurring pozzolans of volcanic origin.
Pozzolans for Lime Mortars. Materials which enable lime mortars to set
more rapidly include ash and brick dust. Known as 'pozzolans' after the
volcanic additives used by the Romans, these materials are widely found in
the lime mortars used in old buildings and monuments. Where conservation
work is required, new mortars ought to match these mortars, not only to
ensure continuity with the past, but also to ensure that the new work is
both visually and physically compatible with the old. It is therefore
important that we know more about the performance of these additives.
Lime is a
calcium-containing
inorganic material in which
carbonates,
oxides,
and
hydroxides predominate. In the strict sense of the term, lime is
calcium oxide or
calcium hydroxide. It is also the name of the natural mineral (native
lime) CaO which occurs as a product of coal seam fires and in altered
limestone xenoliths in volcanic ejecta. The word lime originates with its
earliest use as building mortar and has the sense of sticking or adhering.

Geopolymer are inorganic, typically ceramic, materials that form
long-range, covalently bonded, non-crystalline networks. Obsidian
fragments are a component of some geopolymer blends. Commercially produced
geopolymers may be used for fire- and heat-resistant coatings and
adhesives, medicinal applications, high-temperature ceramics, new binders
for fire-resistant fiber composites, toxic and radioactive waste
encapsulation and new cements for concrete. The properties and uses of
geopolymers are being explored in many scientific and industrial
disciplines: modern inorganic chemistry, physical chemistry, colloid
chemistry, mineralogy, geology, and in other types of engineering process
technologies. Geopolymers are part of polymer science, chemistry and
technology that forms one of the major areas of materials science.
Polymers are either organic material, i.e. carbon-based, or inorganic
polymer, for example silicon-based. The organic polymers comprise the
classes of natural polymers (rubber, cellulose),
synthetic organic
polymers (textile fibers, plastics, films, elastomers, etc.) and
natural
biopolymers (biology, medicine, pharmacy). Raw materials used in the
synthesis of silicon-based polymers are mainly rock-forming minerals of
geological origin, hence the name: geopolymer. Joseph Davidovits coined
the term in 1978 and created the non profit French scientific institution
(Association Loi 1901) Institut Géopolymère (Geopolymer Institute).
According to T.F. Yen geopolymers can be classified into two major groups:
pure inorganic geopolymers and organic containing geopolymers, synthetic
analogues of naturally occurring macromolecules. In the following
presentation, a geopolymer is essentially a mineral chemical compound or
mixture of compounds consisting of repeating units, for example silico-oxide
(-Si-O-Si-O-), silico-aluminate (-Si-O-Al-O-), ferro-silico-aluminate
(-Fe-O-Si-O-Al-O-) or alumino-phosphate (-Al-O-P-O-), created through a
process of geopolymerization. This mineral synthesis (geosynthesis) was
first presented at an IUPAC symposium in 1976. Geopolymer cement
categories: Slag-based geopolymer cement. Rock-based geopolymer cement.
Fly ash-based geopolymer cement. Type 1: alkali-activated fly ash
geopolymer. Type 2: slag/fly ash-based geopolymer cement. Ferro-sialate-based
geopolymer cement.
Portland Cement is the most common type of cement in general use
around the world as a basic ingredient of concrete, mortar, stucco, and
non-specialty grout. It was developed from other types of hydraulic lime
in England in the mid 19th century, and usually originates from limestone.
It is a fine powder, produced by heating limestone and clay minerals in a
kiln to form clinker, grinding the clinker, and adding 2 to 3 percent of
gypsum. Several types of Portland cement are available. The most common,
called ordinary Portland cement (OPC), is grey, but white Portland cement
is also available. Its name is derived from its similarity to Portland
stone which was quarried on the Isle of Portland in Dorset, England. It
was named by Joseph Aspdin who obtained a patent for it in 1824. However,
his son William Aspdin is regarded as the inventor of "modern" Portland
cement due to his developments in the 1840s. Portland cement is caustic,
so it can cause chemical burns. The powder can cause irritation or, with
severe exposure, lung cancer, and can contain some hazardous components,
such as crystalline silica and hexavalent chromium. Environmental concerns
are the high energy consumption required to mine, manufacture, and
transport the cement, and the related air pollution, including the release
of
greenhouse gases (e.g., carbon dioxide), dioxin, NOx, SO2, and
particulates. The production of Portland cement contributes to about 10%
of world
carbon dioxide emission. To meet the rising global population,
the International Energy Agency estimated that the cement production is
set to increase between 12 to 23% by 2050. There are several ongoing
researches targeting a suitable replacement of Portland cement by
supplementary cementitious materials. The low cost and widespread
availability of the limestone, shales, and other naturally-occurring
materials used in Portland cement make it one of the lowest-cost materials
widely used over the last century. Concrete produced from Portland cement
is one of the world's most versatile construction materials.
Prestressed Concrete is a form of concrete that is compressed during
its fabrication, in a manner that strengthens it against tensile forces
which will exist when in service. This compression is produced by the
tensioning of high-strength "tendons" located within or adjacent to the
concrete and is done to improve the performance of the concrete in
service. Tendons may consist of single wires, multi-wire strands or
threaded bars that are most commonly made from high-tensile steels, carbon
fiber or aramid fiber. The essence of prestressed concrete is that once
the initial compression has been applied, the resulting material has the
characteristics of high-strength concrete when subject to any subsequent
compression forces and of ductile high-strength steel when subject to
tension forces. This can result in improved structural capacity and/or
serviceability compared with conventionally reinforced concrete in many
situations. In a prestressed concrete member, the internal stresses are
introduced in a planned manner so that the stresses resulting from the
superimposed loads are counteracted to the desired degree. Prestressed
concrete is used in a wide range of building and civil structures where
its improved performance can allow for longer spans, reduced structural
thicknesses, and material savings compared with simple reinforced
concrete. Typical applications include high-rise buildings, residential
slabs, foundation systems, bridge and dam structures, silos and tanks,
industrial pavements and nuclear containment structures. First used in the
late-nineteenth century, prestressed concrete has developed beyond
pre-tensioning to include post-tensioning, which occurs after the concrete
is cast. Tensioning systems may be classed as either monostrand, where
each tendon's strand or wire is stressed individually, or multi-strand,
where all strands or wires in a tendon are stressed simultaneously.
Tendons may be located either within the concrete volume (internal
prestressing) or wholly outside of it (external prestressing). While
pre-tensioned concrete uses tendons directly bonded to the concrete,
post-tensioned concrete can use either bonded or unbonded tendons.
Hollow-Core Slab also known as a voided slab, hollow core plank or
simply a concrete plank is a precast slab of prestressed concrete
typically used in the construction of floors in multi-story apartment
buildings. The slab has been especially popular in countries where the
emphasis of home construction has been on precast concrete, Precast
concrete popularity is linked with low-seismic zones and more economical
constructions because of fast building assembly, lower self weight (less
material), etc. Precast hollow-core elements is also known as the most
sustainable floor/roof system and has far smaller CO2 footprint than even
CLT slabs. The precast concrete slab has tubular voids extending the full
length of the slab, typically with a diameter equal to the 2/3-3/4 the
thickness of the slab. This makes the slab much lighter than a massive
solid concrete floor slab of equal thickness or strength. The reduced
weight also lowers material and transportation costs. The slabs are
typically 120 cm wide with standard thicknesses normally between 15 cm and
50 cm. Reinforcing steel wire rope provides bending resistance. Slabs in
prestressed concrete are usually produced in lengths of up to 200 meters.
The process involves extruding wet concrete along with the prestressed
steel wire rope from a moving mold. The continuous slab is then cut to
required lengths by a large diamond circular saw. Factory production
provides the obvious advantages of reduced time, labor and training.
Another fabrication system produces hollow-core floor slabs in Reinforced
Concrete (not prestressed). These are made on carousel production lines,
directly to exact length, and as a stock product. However, the length is
limited to about 7-8 meters. Especially in Belgium, this method is widely
used in private housing. To meet modern standards (both hollow-core and
massive slab) of soundproofing the floor needs to be covered with a soft
floor covering that is able to dampen the sound of footsteps or a floating
floor screed should be installed. An alternative is to put a strip of
rubber underneath the floor slabs. Hollow-core slabs and wall elements
without prestressed steel wire can be formed by extruders. The size of
these elements will typically range in width from 600 to 2400 mm, in
thickness from 150 to 500 mm, and can be delivered in lengths of up to 24
m. The voids of the hollow core can be used as conduit for installations.
The interior of the core can be coated in order to use it as a ventilation
duct.
Precast Concrete is a construction product produced by casting
concrete in a reusable mold or "form" which is then cured in a controlled
environment, transported to the construction site and lifted into place
("tilt up"). In contrast, standard concrete is poured into site-specific
forms and cured on site. Precast stone is distinguished from precast
concrete using a fine aggregate in the mixture, so the final product
approaches the appearance of naturally occurring rock or stone. More
recently expanded polystyrene is being used as the cores to precast wall
panels. This is lightweight and has better thermal insulation. Precast is
used within exterior and interior walls. By producing precast concrete in
a controlled environment (typically referred to as a precast plant), the
precast concrete is afforded the opportunity to properly cure and be
closely monitored by plant employees. Using a precast concrete system
offers many potential advantages over onsite casting. Precast concrete
production can be performed on ground level, which helps with safety
throughout a project. There is greater control over material quality and
workmanship in a precast plant compared to a construction site. The forms
used in a precast plant can be reused hundreds to thousands of times
before they have to be replaced, often making it cheaper than onsite
casting when looking at the cost per unit of formwork. There are many
different types of precast concrete forming systems for architectural
applications, differing in size, function, and cost. Precast architectural
panels are also used to clad all or part of a building facades or
free-standing walls used for landscaping, soundproofing, and security
walls, and some can be prestressed concrete structural elements.
Stormwater drainage, water and sewage pipes, and tunnels make use of
precast concrete units. To complete the look of the four precast wall
panel types — sandwich, plastered sandwich, inner layer and cladding
panels — many surface finishes are available. Standard cement is white or
grey, though different colors can be added with pigments or paints. The
color and size of aggregate can also affect the appearance and texture of
concrete surfaces. The shape and surface of the precast concrete molds
have an effect on the look: The mold can be made of timber, steel,
plastic, rubber or fiberglass, each material giving a unique finish.
Carbon Friendly Concrete - Carbon Capture
Cement is the world’s most-used building material, and in 2016 alone,
we consumed 4.2 billion metric tons of it—roughly 115,000 Empire State
Buildings by weight. The problem is that
each ton of cement we use
produces more than half a ton of
carbon dioxide. In
other words, the cement industry contributes
5-6% of all global emissions
each year. Small amounts of sodium and potassium found in
Degerhamn’s limestone means the cement produced there can be sold as
“low-alkali”—known to last longer in ocean water because it can withstand
the corrosive effects of salty H2O. The premium low-alkali product, used
for building bridges or tunnels that traverse bodies of seawater, could be
sold at higher prices. Just like that, the factory came back from the
brink. The plant produces 3 million kg of cement every year, but is run by
a staff of just 75. They work in teams of 25-50, in two or three shifts
round the clock.

cement is being developed and utilized as an alternative to conventional
Portland cement for use in transportation, infrastructure, construction
and offshore applications. It relies on minimally processed natural
materials or industrial byproducts to significantly
reduce the carbon
footprint of cement production, while also being highly resistant to many
common concrete durability issues. Geopolymer cements exist which may cure
more rapidly than Portland-based cements.

roofs, although this is debated. Rooftop ponds are another form of green
roofs which are used to treat greywater. Vegetation, soil, drainage layer,

Winch is a mechanical device that is used to pull in (wind up) or let
out (wind out) or otherwise adjust the "tension" of a rope or wire rope
(also called "cable" or "wire cable"). In its simplest form it consists of
a spool and attached hand crank. In larger forms, winches stand at the
heart of machines as diverse as tow trucks, steam shovels and elevators.
The spool can also be called the winch drum. More elaborate designs have
gear assemblies and can be powered by electric, hydraulic, pneumatic or
internal combustion drives. Some may include a solenoid brake and/or a
mechanical brake or ratchet and pawl device that prevents it from
unwinding unless the pawl is retracted.

Metal Working
Metalworking
is the process of working with metals to create individual parts,
assemblies, or large-scale structures. The term covers a wide range of
work from large ships and bridges to precise engine parts and delicate
jewelry. It therefore includes a correspondingly wide range of skills,
processes, and tools.
Metallurgy
is a domain of
materials science and
engineering that studies the physical and
chemical behavior of metallic elements,
their intermetallic compounds, and their mixtures, which are called
alloys. Metallurgy is used to
separate metals from
their ore. Metallurgy is also the technology of metals: the way in
which science is applied to the production of metals, and the engineering
of metal components for usage in products for consumers and manufacturers.
The production of metals involves the processing of ores to extract the
metal they contain, and the mixture of metals, sometimes with other
elements, to produce alloys.
Metallurgy is
distinguished from the craft of metalworking, although metalworking
relies on metallurgy, as medicine relies on medical science, for technical
advancement. The science of metallurgy is subdivided into chemical
metallurgy and physical metallurgy. Metallurgy is subdivided into ferrous
metallurgy (also known as black metallurgy) and non-ferrous metallurgy
(also known as colored metallurgy). Ferrous metallurgy involves processes
and alloys based on iron while non-ferrous metallurgy involves processes
and alloys based on other metals. The production of ferrous metals
accounts for 95 percent of world metal production.
Alchemy.
Extractive
Metallurgy is a branch of metallurgical engineering wherein process
and methods of
extraction of
metals from their natural mineral deposits are studied. The field is a
materials science, covering all aspects of the types of ore, washing,
concentration, separation, chemical processes and extraction of pure metal
and their alloying to suit various applications, sometimes for direct use
as a finished product, but more often in a form that requires further
working to achieve the given properties to suit the applications. The
field of ferrous and non-ferrous extractive metallurgy have specialties
that are generically grouped into the categories of mineral processing,
hydrometallurgy, pyrometallurgy, and electrometallurgy based on the
process adopted to extract the metal. Several processes are used for
extraction of same metal depending on occurrence and chemical
requirements.

Kiln is a
thermally insulated chamber, a type of oven, that produces temperatures
sufficient to complete some process, such as hardening, drying, or
chemical changes. Kilns have been used for millennia to turn objects made
from clay into pottery, tiles and bricks. Various industries use rotary
kilns for pyroprocessing—to calcinate ores, to calcinate limestone to lime
for cement, and to transform many other materials.
Hearth is an open recess in a wall at the
base of a chimney where a fire can be built. Home symbolized as a part of
the fireplace. An area near a fireplace, usually paved and extending out
into a room.
Fireplace is an open
recess that bends inward in a wall at the base of a chimney where a fire
can be built.
Fireplace is a structure made of brick, stone or metal designed to
contain a fire. Fireplaces are used for the relaxing ambiance they create
and for heating a room. Modern fireplaces vary in heat efficiency,
depending on the design.
Chimney
is an architectural ventilation structure made of masonry, clay or metal
that isolates hot toxic exhaust gases or smoke produced by a boiler,
stove, furnace, incinerator or fireplace
from human living areas. Chimneys are typically vertical, or as near as
possible to vertical, to ensure that the gases flow smoothly, drawing air
into the combustion in what is known as the stack, or chimney effect. The
space inside a chimney is called the flue. Chimneys are adjacent to large
industrial refineries, fossil fuel combustion facilities or part of
buildings, steam locomotives and ships.
Refractory material is a material that retains its strength at high
temperatures. ASTM C71 defines refractories as "...non-metallic materials
having those chemical and physical properties that make them applicable
for structures, or as components of systems, that are exposed to
environments above 1,000 °F (811 K; 538 °C)." Refractory materials are
used in furnaces, kilns, incinerators, and reactors. They are also used to
make crucibles and moulds for casting glass and metals and for surfacing
flame deflector systems for rocket launch structures. Today, the iron- and
steel-industry uses approximately 70% of all refractories produced.
Fire Brick is a block of refractory ceramic material used in lining
furnaces, kilns, fireboxes, and fireplaces. A refractory brick is built
primarily to withstand high temperature, but will also usually have a low
thermal conductivity for greater energy efficiency. Usually dense
firebricks are used in applications with extreme mechanical, chemical, or
thermal stresses, such as the inside of a wood-fired kiln or a furnace,
which is subject to abrasion from wood, fluxing from ash or slag, and high
temperatures. In other, less harsh situations, such as in an electric or
natural gas fired kiln, more porous bricks, commonly known as "kiln
bricks" are a better choice. They are weaker, but they are much lighter,
easier to form, and insulate far better than dense bricks. In any case,
firebricks should not spall, and their strength should hold up well during
rapid temperature changes.
Smelting is a form of extractive metallurgy; its
main use is to produce a base metal from its ore. This includes production
of silver, iron, copper and other base metals from their ores. Smelting
makes use of
Heat and a chemical reducing agent to decompose the ore,
driving off other elements as gases or slag and leaving just the metal
base behind. The reducing agent is commonly a source of carbon such as
coke, or in earlier times charcoal.
Melting
is the process whereby
Heat
changes something from a
Solid to a
Liquid. Reduce or cause to be reduced
from a solid to a liquid state, usually by heating. Become or cause to
become soft or liquid.
Sublimation.
Furnace is a
device used to heat and melt metal ore to remove gangue. The name derives
from Latin word fornax, which means oven. The heat energy to fuel a
furnace may be supplied directly by fuel combustion, by electricity such
as the electric arc furnace, or through induction heating in induction
furnaces.
Blast Furnace
is a type of metallurgical furnace used for
smelting to produce industrial
metals, generally pig iron, but also others such as lead or copper. Blast
refers to the combustion air being "forced" or supplied above atmospheric
pressure. In a blast furnace, fuel (coke), ores, and flux (limestone) are
continuously supplied through the top of the furnace, while a hot blast of
air (sometimes with oxygen enrichment) is blown into the lower section of
the furnace through a series of pipes called tuyeres, so that the chemical
reactions take place throughout the furnace as the material falls
downward. The end products are usually molten metal and slag phases tapped
from the bottom, and waste gases (flue gas) exiting from the top of the
furnace. The downward flow of the ore along with the flux in contact with
an upflow of hot, carbon monoxide-rich combustion gases is a
countercurrent exchange and chemical reaction process. In contrast, air
furnaces (such as reverberatory furnaces) are naturally aspirated, usually
by the convection of hot gases in a chimney flue. According to this broad
definition, bloomeries for iron, blowing houses for tin, and smelt mills
for lead would be classified as blast furnaces. However, the term has
usually been limited to those used for smelting iron ore to produce pig
iron, an intermediate material used in the production of commercial iron
and steel, and the shaft furnaces used in combination with sinter plants
in base metals smelting.

Glass Forge
is to make or shape a metal object by heating it in a fire or furnace and
beating or hammering it.
Create by
hammering. Make something, usually for a specific function. Make out of
components, sometimes in an improvising manner. A furnace consisting of a
special hearth where metal is heated before shaping. A workplace where
metal is worked by heating and hammering.
Forging is a manufacturing process involving the shaping of
metal using localized compressive forces. The blows are delivered with a
hammer or a power hammer or a die. Forging is often classified
according to the temperature at which it is performed:
cold forging, which is a
type of cold working, warm forging, or
hot forging,
which is a type of hot
working.
Forged steel is generally
stronger and more reliable
than castings and plate steel due to the
fact that the grain flows of the steel are altered, conforming to the
shape of the part. Forging is generally tougher than alternatives and will
handle impact better than castings.

Casting is a manufacturing process in which a liquid
material is usually
poured into a mold, which contains a hollow cavity of
the desired shape, and then allowed to solidify. The solidified part is
also known as a casting, which is ejected or broken out of the mold to
complete the process. Casting materials are usually metals or various cold
setting materials that cure after mixing two or more components together;
examples are epoxy, concrete, plaster and clay. Casting is most often used
for making complex shapes that would be otherwise difficult or
uneconomical to make by other method.

Chemistry
Iron is a
chemical element with symbol Fe (from Latin: ferrum) and atomic number 26.
It is a metal in the first transition series. It is by mass the most
common element on Earth, forming much of Earth's outer and inner core. It
is the fourth most common element in the Earth's crust.
Iron Pillar of Delhi was made approximately 402 CE.
Adding carbon to iron to make steel does
make it stronger and tougher, up to a point. Then it will get stronger but
less tough (ie like cast iron). Carbon strengthens iron by distorting its
crystal lattice. This distortion is similar in effect to work hardening.
Steel is an alloy of iron and other
elements,
primarily
carbon, that is widely used in construction and other
applications because of its
high tensile strength and low cost. Steel's
base metal is iron, which is able to take on two
crystalline forms
(allotropic forms), body centered cubic (BCC) and face centered cubic
(FCC), depending on its temperature.
Stainless Steel is a steel alloy, with a minimum of 11% chromium
content by mass and a maximum of 1.2% carbon by mass. Stainless steels are
most notable for their
corrosion resistance,
which increases with increasing chromium content. Additions of molybdenum
increases corrosion resistance in reducing acids and against pitting
attack in chloride solutions. Thus, there are numerous grades of stainless
steel with varying chromium and molybdenum contents to suit the
environment the alloy must endure. Resistance to corrosion and staining,
low maintenance, and familiar luster make stainless steel an ideal
material for many applications where both the strength of steel and
corrosion resistance are required. Stainless steel is rolled into sheets,
plates, bars, wire, and tubing to be used in: cookware, cutlery, surgical
instruments, major appliances; construction material in large buildings,
such as the Chrysler Building; industrial equipment (for example, in paper
mills, chemical plants, water treatment); and storage tanks and tankers
for chemicals and food products (for example, chemical tankers and road
tankers). Corrosion resistance, the ease with which it can be steam
cleaned and sterilized, and lack of need for surface coatings has also
influenced the use of stainless steel in commercial kitchens and food
processing plants.
Galvanization is the process of applying a protective zinc coating to
steel or iron, to prevent rusting. The most common method is hot-dip
galvanizing, in which parts are submerged in a bath of molten zinc.

Steel utilizes a specially developed martensitic-aging stainless steel
alloy that can achieve
tensile
strength in excess of 2000 MPa, we’ve achieved a strength-to-weight
ratio that can take on the world’s best. The resilient ride of steel, very
high impact strength (similar to armour plating) and fatigue
resistance combine to provide an extraordinary material – 953 maraging

HY-80 is
a high-tensile, high yield strength, low alloy steel. It was developed for
use in naval applications, specifically the development of pressure hulls
for the US nuclear submarine program and is still currently used in many
naval applications. It is valued for its strength to weight ratio. The
"HY" steels are designed to possess a high yield strength (strength in
resisting permanent plastic deformation). HY-80 is accompanied by HY-100
and HY-130 with each of the 80, 100 and 130 referring to their yield
strength in ksi (80,000 psi, 100,000 psi and 130,000 psi). HY-80 and
HY-100 are both weldable grades; whereas, the HY-130 is generally
considered unweldable. Modern steel manufacturing methods that can
precisely control time/temperature during processing of HY steels has made
the cost to manufacture more economical. HY-80 is considered to have good
corrosion resistance and has good formability to supplement being weldable.
Using HY-80 steel requires careful consideration of the welding processes,
filler metal selection and joint design to account for microstructure
changes, distortion and stress concentration.
Metal is a material (an
element, compound, or
alloy) that is typically hard, opaque, shiny, and
has good electrical and thermal
conductivity. Metals are generally
malleable—that is, they can be hammered or pressed permanently out of
shape without breaking or cracking—as well as fusible (able to be fused or
melted) and ductile (able to be drawn out into a thin wire). About 91 of
the 118 elements in the periodic table are metals, the others are
nonmetals or metalloids. Some elements appear in both metallic and
non-metallic forms.
Alloy is a combination of metals or metals combined with one or more
other elements. For example, combining the metallic elements gold and
copper produces red gold, gold and silver becomes white gold, and silver
combined with copper produces sterling silver. Elemental iron, combined
with non-metallic carbon or silicon, produces alloys called steel or
silicon steel. The resulting mixture forms a substance with properties
that often differ from those of the pure metals, such as increased
strength or hardness. Unlike other substances that may contain metallic
bases but do not behave as metals, such as aluminium oxide (sapphire),
beryllium aluminium silicate (emerald) or sodium chloride (salt), an alloy
will retain all the properties of a metal in the resulting material, such
as electrical conductivity, ductility, opaqueness, and luster. Alloys are
used in a wide variety of applications, from the steel alloys, used in
everything from buildings to automobiles to surgical tools, to exotic
titanium-alloys used in the aerospace industry, to beryllium-copper alloys
for non-sparking tools. In some cases, a combination of metals may reduce
the overall cost of the material while preserving important properties. In
other cases, the combination of metals imparts synergistic properties to
the constituent metal elements such as corrosion resistance or mechanical
strength. Examples of alloys are steel, solder, brass, pewter, duralumin,
bronze and amalgams. An alloy may be a solid solution of metal elements (a
single phase, where all metallic grains (crystals) are of the same
composition) or a mixture of metallic phases (two or more solutions,
forming a microstructure of different crystals within the metal).
Intermetallic compounds are alloys with a defined stoichiometry and
crystal structure. Zintl phases are also sometimes considered alloys
depending on bond types (see Van Arkel–Ketelaar triangle for information
on classifying bonding in binary compounds). Alloys are defined by a
metallic bonding character. The alloy constituents are usually measured by
mass percentage for practical applications, and in atomic fraction for
basic science studies. Alloys are usually classified as substitutional or
interstitial alloys, depending on the atomic arrangement that forms the
alloy. They can be further classified as homogeneous (consisting of a
single phase), or heterogeneous (consisting of two or more phases) or
intermetallic.
Tungsten Carbide
is a chemical compound (specifically, a carbide) containing equal parts of
tungsten
and
carbon atoms. In its most basic
form, tungsten carbide is a fine gray powder, but it can be pressed and
formed into shapes for use in
industrial machinery, cutting tools, abrasives, armor-piercing rounds,
other tools and instruments, and jewelry. Tungsten carbide is
approximately two times stiffer than steel, with a Young's modulus of
approximately 530–700 GPa (77,000 to 102,000 ksi), and is double the
density of steel—nearly midway between that of lead and gold. It is
comparable with corundum (α-Al 2O3) in hardness and can only be polished
and finished with abrasives of superior hardness such as cubic boron
nitride and diamond powder, wheels, and compounds.
Damascus Steel was the forged steel comprising the blades of
swords smithed in the Near East from ingots of
wootz
steel imported from India and Sri Lanka. These swords are
characterized by distinctive patterns of banding and mottling reminiscent
of flowing water. Such blades were reputed to be tough, resistant to
shattering, and capable of being honed to a sharp, resilient edge.
Knives (eating utensils).
Ulfberht Swords are a group of medieval swords found in Europe, dated
to the 9th to 11th.

Graphene (nano technology)
Bronze is an alloy consisting primarily of
copper,
commonly with about 12% tin and often with the addition of other metals
(such as aluminium, manganese, nickel or zinc) and sometimes non-metals or
metalloids such as arsenic, phosphorus or silicon. These additions produce
a range of alloys that may be harder than copper alone, or have other
useful properties, such as stiffness, ductility, or machinability.
Copper is a soft,
malleable, and ductile metal with very high thermal and
electrical conductivity.
A freshly exposed surface of pure copper has a reddish-orange color.
Copper is used as a conductor of heat and electricity, as a building
material, and as a constituent of various metal alloys, such as sterling
silver used in jewelry, cupronickel used to make marine hardware and
coins, and constantan used in strain gauges and thermocouples for
temperature measurement. First source of the metal to be used by humans,
ca. 8,000 BC. It was the first metal to be smelted from its ore, ca. 5,000
BC. The first metal to be cast into a shape in a mold, ca. 4,000 BC and
the first metal to be purposefully alloyed with another metal, tin, to
create bronze, ca. 3,500 BC. Atomic number 29, Protons: 29 - Neutrons: 35

Anti-Microbial
Aluminium is a silvery-white, soft, nonmagnetic, ductile metal in the
boron group. By mass, aluminium makes up about 8% of the Earth's crust; it
is the third most abundant element after oxygen and silicon and the most
abundant metal in the crust, though it is less common in the mantle below.
Aluminium metal is so chemically reactive that native specimens are rare
and limited to extreme reducing environments. Instead, it is found
combined in over 270 different minerals. The chief ore of aluminium is
bauxite. Aluminium is remarkable for the metal's low density and its
ability to resist corrosion through the phenomenon of passivation.
Aluminium and its alloys are vital to the aerospace industry and important
in transportation and building industries, such as building facades and
window frames. The oxides and sulfates are the most useful compounds of
aluminium. Despite its prevalence in the environment, no known form of
life uses aluminium salts metabolically, but aluminium is well tolerated
by plants and animals. Because of these salts' abundance, the potential
for a biological role for them is of continuing interest, and studies
continue. Protons: 13 - Neutrons: 14 - Electrons per shell 2, 8, 3.
Metal Foam is a
cellular structure consisting of a solid metal (frequently aluminium) with
gas-filled pores comprising a large portion of the volume. The pores can
be sealed (closed-cell foam) or interconnected (open-cell foam). The
defining characteristic of metal foams is a high porosity: typically only
5–25% of the volume is the base metal, making these ultralight materials.
The strength of the material is due to the square-cube law. Metallic foams
typically retain some physical properties of their base material. Foam
made from non-flammable metal remains non-flammable and can generally be
recycled as the base material. Its coefficient of thermal expansion is
similar while thermal conductivity is likely reduced. Although many
patents describe feasible topological structures, constitutive materials,
and production methods, metal foams cannot be considered a commodity and
relatively few commercial producers are available worldwide.
Slag is
the glass-like by-product left over after a desired metal has been
separated (i.e., smelted) from its raw ore. Slag is usually a mixture of
metal oxides and silicon dioxide. However, slags can contain metal
sulfides and elemental metals.
Blacksmith is a metal-smith who creates objects from
wrought iron or steel by forging the metal, using tools to hammer, bend,
and cut (cf. whitesmith). Blacksmiths produce objects such as gates,
grilles, railings, light fixtures, furniture, sculpture, tools,
agricultural implements, decorative and religious items and cooking
utensils.
Boilermaker is a
trained
craftsman who produces steel fabrications from plates and tubes. The
name originated from craftsmen who would fabricate boilers, but they may
work on projects as diverse as bridges to blast furnaces to the
construction of mining equipment.
Pipefitter is a
tradesperson
who installs, assembles, fabricates, maintains and repairs mechanical
piping systems. Typical industrial process pipe is under high pressure,
which requires metals such as carbon steel, stainless steel, and many
different alloy metals fused together through precise cutting, threading,
grooving (Victaulic), bending and welding. A
Plumber concentrates on lower
pressure piping systems for sewage and potable water (tap water), in the
industrial, commercial, institutional, or residential atmosphere. Utility
piping typically consists of copper, PVC, CPVC, polyethylene, and
galvanized pipe, which is typically glued, soldered, or threaded. Other
types of piping systems include steam, ventilation, hydraulics, chemicals,
fuel, and oil.
Welder
Anvil is
a block with a hard surface on which another object is struck. The block
is as massive as it is practical, because the higher the inertia of the
anvil, the more efficiently it causes the energy of the striking tool to
be transferred to the work piece. On a quality anvil the smith's hammer
should rebound with almost as much energy as the smith puts into the
downward stroke, ultimately making the smith's job easier and less
physically strenuous. In most cases the anvil is used as a forging tool.
Before the advent of modern welding technology, it was a primary tool of
metal workers.

Machinist Tools
Annealing in metallurgy and materials science, is a
heat treatment that alters the physical and sometimes chemical properties
of a material to increase its ductility and
reduce its
hardness, making it
more workable. It involves heating a material to above its
recrystallization temperature, maintaining a suitable temperature, and
then cooling.
Tempering is a process of
heat treating, which is
used to increase the toughness of iron-based alloys. Tempering is usually
performed after hardening, to reduce some of the excess hardness, and is
done by heating the metal to some temperature below the critical point for
a certain period of time, then allowing it to cool in still air. The exact
temperature determines the amount of hardness removed, and depends on both
the specific composition of the alloy and on the desired properties in the
finished product. For instance, very hard tools are often tempered at low
temperatures, while springs are tempered to much higher temperatures.
Temper is to bring to a desired
consistency, texture, or hardness by a process of gradually heating and
cooling. The elasticity and hardness of a metal object; its ability to
absorb considerable energy before cracking. Harden by reheating and
cooling in oil.
Heat Treating is a group of industrial and
metalworking processes used to alter the physical, and sometimes chemical,
properties of a material. The most common application is metallurgical.
Heat treatments are also used in the manufacture of many other materials,
such as glass. Heat treatment involves the use of heating or chilling,
normally to extreme temperatures, to achieve a desired result such as
hardening or softening of a material. Heat treatment techniques include
annealing, case hardening, precipitation strengthening, tempering,
normalizing and quenching.
Quenching is the rapid cooling of a workpiece
to obtain certain material properties. A type of heat treating, quenching
prevents undesired low-temperature processes, such as phase
transformations, from occurring. It does this by reducing the window of
time during which these undesired reactions are both thermodynamically
favorable, and kinetically accessible; for instance, quenching can reduce
the crystal grain size of both metallic and plastic materials, increasing
their hardness.
Hardening is a metallurgical and metalworking
process used to increase the hardness of a metal. The hardness of a metal
is directly proportional to the uniaxial yield stress at the location of
the imposed strain. A harder metal will have a higher resistance to
plastic deformation than a less hard metal.
Alloy retains its memory at high temperatures. Even after the
hundredth time the material returns to its original shape when heated.
Grinding is an abrasive machining process that uses
a grinding wheel as the cutting tool. A wide variety of machines are used
for grinding: Hand-cranked knife-sharpening stones (grindstones). Handheld
power tools such as angle grinders and die grinders. Various kinds of
expensive industrial machine tools called grinding machines. Bench
grinders often found in residential garages and basements.
Sander is a power tool used to smooth surfaces
by abrasion with sandpaper. Sanders have a means to attach the sandpaper
and a mechanism to move it rapidly contained within a housing with means
to hand-hold it or fix it to a workbench.
Polishing and buffing are finishing processes for
smoothing a workpiece's surface using an abrasive and a work wheel or a
leather strop. Technically polishing refers to processes that use an
abrasive that is glued to the work wheel, while buffing uses a loose
abrasive applied to the work wheel. Polishing is a more aggressive process
while buffing is less harsh, which leads to a smoother, brighter finish. A
common misconception is that a polished surface has a mirror bright
finish, however most mirror bright finishes are actually buffed.

Welding
is a fabrication or sculptural process that joins materials, usually
metals or thermoplastics, by causing fusion, which is distinct from lower
temperature metal-joining techniques such as brazing and soldering, which
do not melt the base metal. In addition to melting the base metal, a
filler material is often added to the joint to form a pool of molten
material (the weld pool) that cools to form a joint that can be as strong,
or even stronger, than the base material. Pressure may also be used in
conjunction with heat, or by itself, to produce a weld.
Welder

fusing materials together. The term welder refers to the operator, the
machine is referred to as the welding power supply. The materials to be
joined can be metals (such as steel, aluminum, brass, stainless steel
etc.) or varieties of plastic or polymer. Welders typically have to have
good dexterity and attention to detail, as well as some technical
knowledge about the materials being joined and best practices in the
field.

Friction Welding is a solid-state welding process that
generates heat through mechanical friction between workpieces in relative
motion to one another, with the addition of a lateral force called "upset"
to plastically displace and fuse the materials. Because no melting occurs,
friction welding is not a fusion welding process in the traditional sense,
but more of a forge welding technique. Friction welding is used with
metals and thermoplastics in a wide variety of aviation and automotive
applications.
Cold
Welding is a solid-state welding process in which joining takes place
without fusion/heating at the interface of the two parts to be welded.
Unlike in the fusion-welding processes, no liquid or molten phase is
present in the joint. Cold welding was first recognized as a general
materials phenomenon in the 1940s. It was then discovered that two clean,
flat surfaces of similar metal would strongly adhere if brought into
contact under vacuum. Newly discovered micro- and nano-scale cold welding
has already shown great potential in the latest
nanofabrication processes. The
reason for this unexpected behavior is that when the atoms in contact are
all of the same kind, there is no way for the atoms to “know” that they
are in different pieces of copper. When there are other atoms, in the
oxides and greases and more complicated thin surface layers of
contaminants in between, the atoms “know” when they are not on the same part.
Distilling
Distill is remove
impurities from, increase the concentration of, and separate through the
process of distillation.
Distilling.
Distillation is a process of separating the
component or substances from a liquid mixture by selective
Evaporation and
condensation. Distillation may result in essentially complete separation
(nearly pure components), or it may be a partial separation that increases
the concentration of selected components of the mixture. In either case
the process exploits differences in the volatility of the mixture's
components. In industrial
chemistry,
distillation is a unit operation of practically universal importance, but
it is a physical separation process and not a
chemical reaction.
Sublimation is the transition of a substance
directly from the solid to the gas phase without passing through the
intermediate
liquid phase. Sublimation is an endothermic phase transition
that occurs at
temperatures and pressures below a substance's triple point
in its phase diagram. The reverse process of sublimation is deposition or desublimation, in which a substance passes directly from a gas to a solid
phase. Sublimation has also been used as a generic term to describe a
solid-to-gas transition (sublimation) followed by a gas-to-solid
transition (deposition).
Evaporation.
Condense is to undergo
condensation and change from a
gaseous to a liquid state and fall in
drops. Cause a gas or vapor to change into a liquid.
Become more compact or
concentrated.

Drinking Alcohol Dangers.
Four Major Steps to Making Spirits
Sourcing the initial
ingredient, which is a component of a mixture or compound.
Fermenting the sourced
material (that is, adding yeast which breaks down the sourced material to
create alcohol). Ending product is a drink with 4-15% alcohol.
Distilling the fermented wash from step 2
(that is,
boiling the liquid to separate out the alcohol and increase the
alcohol content to >40% alcohol). Distilling is a required step to make
spirits. Wine and beer are not distilled; hence are not called spirits and
have lower alcoholic content than spirits.
Aging of the distilled spirit. This is an optional step, but
storing the spirit in oak barrels will add some flavor and
gold/red/yellowish coloring. For example, whether or not a Tequila was
stored in oak barrels determines whether the Tequila is white (not stored
in oak barrels), or gold (was stored in oak barrels). This is also how
whiskey gets much of it's color and flavor.
Additionally,
flavoring drinks at various steps may in
turn make different spirits (gin is vodka that has been flavored with
juniper berries during distillation). Mixing different drinks also results
in new drinks (for example, wine + brandy = vermouth).
Drinks like
Wine and Beer that are not
spirits and do not need distilling.
Spirits
Whiskey: Grains (malted barley, wheat, corn) ->
fermentation ->
distillation -> aging. Note that whiskey is basically made by
distilling beer. Aging in
oak barrels is what gives whiskey the distinct
color. Prior to storage, the distilled liquid is clear. Some
whiskey tends
to be very smokey/peaty in
flavor. This is
because the grain was dried in a peat powered kiln prior to being
fermented, and the smoke from the peat imparts flavor. Islay scotch tends
to have an extremely strong smokey flavor and
smell.
Scotch is any
whiskey made in Scotland
(usually uses malted barley, though may also use wheat and rye). Bourbon
is an American whiskey made specifically from corn.
Brandy:
Grapes (sourcing) -> fermentation
-> distilling. Basically distilled
wine. Cognac is a variety of
brandy
from the Cognac region in France.
Rum:
Sugarcane or
Molasses -> fermentation -> distilling. Like you'd expect
out of something made from sugarcane or molasses, rum tends to
be on the sweeter side.
Rum is made by fermenting and distilling
cane sugar.
Vodka: Pretty
much anything (grapes, grains, potatoes) -> fermentation-> distilling.
In making
vodka, the liquid is distilled to 90%+ alcohol to remove most
taste and aromas of the source material. It is then diluted with water to
40% alcohol.
Tequila: Blue
Agave plant
-> fermentation -> distillation -> aging. White/silver
tequila has not
been aged in oak barrels. Gold tequila is aged in oak barrels (hence the
color).
Gin: Vodka with
juniper berries
added during distillation.
Gin, like the others
made with grain, starts life as a beer, which is then distilled to a
high proof like vodka. ...Gin is meant to be mixed, There are more classic
cocktails made with gin than with any other spirit.
Liqueur or cordials
(not
liquor, which is simply another word for spirits) is a generic term
for a spirit with added
sugar (or some other sweetener) and flavored with
fruit, cream, herbs, spices, flowers or nuts. Examples of common liqueurs
include Fireball, Fernet-Branca, and Jagermeister.
Schnapps.
Cognac
is produced by twice distilling white wines produced in any of the
designated growing regions. After the grapes are pressed, the juice is
left to ferment for 2–3 weeks, with the region's native, wild yeasts
converting the sugar into alcohol; neither sugar nor sulfur may be added.
At this point, the resulting wine is about 7 to 8% alcohol. Distillation
takes place in traditionally shaped Charentais copper alembic stills, the
design and dimensions of which are also legally controlled. Two
distillations must be carried out; the resulting eau de vie is a
colourless spirit of about 70% alcohol. Once distillation is complete, it
must be aged in Limousin oak casks for at least two years before it can be
sold to the public. It is typically put into casks at an alcohol by volume
strength around 70%. As the cognac interacts with the oak barrel and the
air, it evaporates at the rate of about 3% each year, slowly losing both
alcohol and water. This phenomenon is called locally la part des anges, or
"the angels' share". When more than ten years pass in the oak barrel, the
cognac's alcohol content decreases to 40% in volume. The cognac is then
transferred to "large glass bottles called bonbonnes", then stored for
future "blending." Since oak barrels stop contributing to flavor after
four or five decades, longer aging periods may not be beneficial. The
white wine used in making cognac is very dry, acidic, and thin. Though it
has been characterized as "virtually undrinkable", it is excellent for
distillation and aging. It may be made only from a strict list of grape
varieties. The age of the cognac is calculated as that of the youngest
component used in the blend. The blend is usually of different ages and
(in the case of the larger and more commercial producers) from different
local areas. This blending, or marriage, of different eaux de vie is
important to obtain a complexity of flavours absent from an eau de vie
from a single distillery or vineyard. Each cognac house has a master
taster (maître de chai), who is responsible for blending the spirits, so
that cognac produced by a company will have a consistent house style and
quality. In this respect, it is similar to the process of blending whisky
or non-vintage Champagne to achieve a consistent brand flavor.
Non-Sprits - No Distillation Needed
Beer: Grains (barley, wheat, corn) ->
fermentation "Hops" are added for bitter flavoring.
Wine:
Grapes (sourcing) -> fermentation
-> aging. Whether or not
grape skin was present during
fermentation
determines whether the wine is a white wine (grape juice without skin was
fermented), or a red wine (skin was included during fermentation).
Carbonated wine is called sparkling wine. Carbonated wine specifically
from the Champagne region of France is called Champagne.
