6. The Global Warming & Architecture Introduction

Introduction
In the first half of the twentieth century, most scientists did not believe that increased
CO2 levels would result in global warming. It was thought that at current atmospheric
concentrations, the gas already absorbed all the available long-wave radiation; thus any increases
in CO2 would not change the eradicative heat balance of the planet but might augment plant
growth.
Global warming is already taking place and has become the biggest challenge of our
time. The challenge is to find ways for the world to switch from a path of increasing emissions to
a path of more high advanced technologies where the majority of the GHG emissions are
eliminated.
Buildings have a significant impact on energy use and environment. Commercial and
residential buildings use almost 40% of the primary energy and approximately 70% of the electricity
in the United States (EIA 2005). The energy used by the building sector continues to increase,
primarily because new buildings are constructed faster than old ones are retired. Electricity
consumption in the commercial building sector doubled between 1980 and 2000, and is expected to
increase another 50% by 2025 (EIA 2005).
Zero carbon architecture (ZCA) is a popular term to describe a buildings use with zero
net energy consumption and zero carbon emissions annually. Zero carbon architecture can be
used autonomously from the energy grid supply – energy can be harvested on-site usually in
combination with energy producing technologies like Solar and Wind while reducing the overall
use of energy with extremely efficient HVAC and Lighting technologies.
The Zero-Net design principle is becoming more practical in adopting due to the
increasing costs of traditional fossil fuels and their negative impact on the planet's climate and
ecological balance.
Understandably the developing countries want the right to economically expand the
fastest way they can, like developed nations have been doing for the past 100 years. Developing
countries face a difficult decision, whether to sacrifice their economic development for
protection against possible ecological problems in the near future.
The Kyoto Protocol (2005) is a protocol to the United Nations Framework Convention
on Climate Change (UNFCCC), aimed at fighting warming. The objective of the Kyoto climate
change conference was to establish a legally binding international agreement, whereby all the
participating nations commit themselves to tackling the issue of global warming and GHG
emissions. The target agreed upon was an average reduction of 5.2% from 1990 levels by the
year 2012.
Nanotechnology, the manipulation of matter at the molecular scale, is bringing new
materials and new possibilities to industries as diverse as electronics, medicine, energy and
aeronautics. Our ability to design new materials from the bottom up is impacting the building
industry as well. New materials and products based on nanotechnology can be found in building
insulation, coatings, and solar technologies.

Century
Approach
In the first half of the twentieth century, most scientists did not believe that increased CO2 levels
would result in global warming. It was thought that at current atmospheric concentrations, the
gas already absorbed all the available long-wave radiation; thus any increases in CO2 would not
change the radiative heat balance of the planet but might augment plant growth.
Other mechanisms of climatic change, although highly speculative, were given more credence,
especially changes in solar luminosity, atmospheric transparency, and the Earth's orbital
elements.

INTRODUCTION
U1.1. The Global warming:U [37]
Global warming is the increase in the average temperature of Earth's near-surface air and
oceans since the mid-20th century and its projected continuation.Global surface temperature
increased 0.74 ± 0.18 °C (1.33 ± 0.32 °F) between the start and the end of the 20th century.
[FIG.1.1]
The greenhouse effect is a natural phenomenon that is essential to keeping the Earth’s
surface warm. Like a greenhouse window, greenhouse gases allow sunlight to enter and then
prevent heat from leaving the atmosphere. Water vapor (H2O) is the most important greenhouse
gas, followed by carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), halocarbons, and
ozone (O3). Human activities—primarily burning fossil fuels—are increasing the concentrations
of these gases, amplifying the natural greenhouse effect. Image courtesy of the Marion Koshland
Science Museum of the National Academy of Sciences.[2]

are changes in addition to rising temperatures.

U1.2. Global Warming Timeline & the Industrial Revolution:
The timeline of this slide is from 1870 to the present. It illustrates a steady increase in
concentrations of CO2 in the atmosphere. For thousands of years, the CO2 concentrations in the
atmosphere have been fairly constant at about 280 ppm .In the last 400 years or so,
corresponding to the start of the Industrial Age, CO2 has increased to about 380 ppm.[3]
[FIG.1.3]
The Industrial Revolution began in Britain in the 1700s, and spread to the rest of the
world, beginning with the United States. The use of machinery and factories led to mass
production, which in turn led to the development of numerous environmental hazards .[3]
Effects of Urbanization During the Industrial Revolution:
- Harmful to the Environment-Class Divide-Low Standard of Living
- Change in Family Structure-Catalyst for Socialist Revolution

12. The Global Warming & Architecture Part-one- The 20th
Century
Prior to the Industrial Revolution, the amount of carbon dioxide released to the atmosphere by
natural processes was almost exactly in balance with the amount absorbed by plants and other
“sinks” on the Earth’s surface.[3]
Model simulations of 20th century climate variations more closely match observed
temperature when both natural and human influences are included. Black line shows observed
temperatures. Blue-shaded regions show projections from models that only included natural
forcing (solar activity and volcanoes). Red-shaded regions show projections from models that
include both natural and human forcing.[3]

U1.3. Carbon Dioxide Emissions:
Since about 1750 human activity has increased the concentration of carbon dioxide and
other greenhouse gases. Measured atmospheric concentrations of carbon dioxide are currently
100 ppmv higher than pre-industrial levels.
Currently in the world 40% of all CO2 emissions are caused by power plants. These are
burning coal, natural gas and diesel fuel. Some power plants burn garbage, some burn methane
made from garbage. And discounting those super green electrical generating plants designed to
issue negligible pollutants, all of our power plants let loose into the atmosphere CO2.
33% of all the CO2 sent forth is the product of cars and trucks. Internal combustion
engines burning fossil fuels…gasoline and diesel spew forth a retching amount of
CO2.[6]

REASONS OF WARMING
U2.1. Cultural & Technical Transformation:U
Liberalism caused our environmental crisis:
Under liberal impetus, we removed social roles and allowed people to, just by having a
line of personal credit, take on responsibility for more things than they can biologically
understand.[8]
Approximately 90% of humanity do nothing but consume beyond reason, leave behind a
huge mess, and then blame those in authority for the disaster the 90% have created. Every
“revolution” fits this pattern, although they have a narrative that says otherwise.[8]
There was a sudden change and increase in man’s capacity to have control over nature,
which by 17th century had begun to advance beyond the technical frontiers of Renaissance.
There was change in the nature of human consciousness, in response to major changes taking
place in the society. It gave birth to the cultural transformation taking place in the society.[5]

Rotary steam power and the iron frame came into being at around the same time through the
interdependent efforts of three men:

The first cast-iron bridge was built which was 30.5m (100ft) span over the severn near
Coalbrookdale in 1779& The area around Iron bridge is described by those promoting it as a
tourist destination as the “Birthplace of the Industrial Revolution”[5]

15. The Global Warming & Architecture Part-one- The 20th

U2.2. The Buildings Sector:
The buildings sector encompasses both residential and commercial (including
institutional) buildings. The sector accounts for 15.3 % of global GHG emissions, including 9.9
% for commercial buildings and 5.4 % for residential; CO2 accounts for nearly all emissions
[FIG.2.2].
Emissions from the building sector are predominantly a function of energy consumption
for diverse purposes that can be organized into three broad categories: public electricity use,
direct fuel combustion, and district heating. Public electricity use includes lighting,
appliance use, refrigeration, air conditioning, and to some extent space heating and cooking.
Emissions from the building sector vary widely by country in both absolute and per
capita terms [FIG.2.3], and depend greatly on the degree of electrification, the level of
urbanization, the amount of building area per capita, the prevailing climate, as well as national
and local policies to promote efficiency.
In addition, building sector emissions vary by composition [FIG.2.4], reflecting different
space heating needs and carbon intensities in the electricity sector.
There is an important correlation between building emissions and socioeconomic
development levels. In general, building emissions are higher in industrialized countries, both in
per capita terms [FIG.2.3] and as a percentage of total country emissions [FIG.2.5] with
variances due to climate, fuel mix and other factors. Thus, development has an important effect
on emissions from the building sector, implying that building efficiency becomes more
significant as countries become more prosperous.[3]
[FIG.2.2.] Sources & Notes: IEA, 2004a.
Absolute emissions in this sector, estimated here for 2000, are 6,418 MtCO2.

17. The Global Warming & Architecture Part-one- The 20th
Century
U2.2.1. The U.S. Energy Consumption:
By creating a sector termed “Buildings,” which combines the residential and commercial
sectors and that part of the industrial sector containing industrial buildings and building
materials, a new and very different picture emerges.
This picture clearly illustrates the problem and the sectors that must be carefully investigated in
order to effect a change.
In this picture, Architecture consumes approximately 48-50 % of all U.S. the energy
produced and is responsible for 46 % of all U.S. CO2 emissions annually, almost double any
other sector. It’s also the fastest growing energy-consuming and emissions sector. Buildings are
among the most long-lived physical artifacts society produces. They are typically used for 50-
100 years, so their inertia has a major impact on future energy use and emissions patterns.
Today’s architecture will be with us for a long time. Architects design most buildings and
specify all the materials used in their construction. The design of a building—its form,
fenestration, construction materials and finishes—largely determines the building’s lifetime
energy consumption and gas emission.[2]
[FIG.2.6]

18. The Global Warming & Architecture Part-one- The 20th
Century
U2.3. The Human Sources:
The main sources of greenhouse gases due to human activity are:
-Burning of fossil fuels and deforestation leading to higher carbon dioxide concentrations.
-Land use change (mainly deforestation in the tropics) account for up to one third of total
anthropogenic CO2 emissions.
-Livestock enteric fermentation and manure management, paddy rice farming, land use and
wetland changes, pipeline losses, and covered vented landfill emissions leading to higher
methane atmospheric concentrations.
-Many of the newer style fully vented septic systems that enhance and target the fermentation
process also are sources of atmospheric methane.
-Use of chlorofluorocarbons (CFCs) in refrigeration systems, and use of CFCs fire suppression
systems and manufacturing processes.
-Agricultural activities, including the use of fertilizers that lead to higher nitrous oxide (N2O)
concentrations.[6]
[FIG.2.7]
The seven sources of CO2 from fossil fuel combustion are:
1. Solid fuels (e.g., coal): 35%
2. Liquid fuels (e.g., gasoline, fuel oil): 36%
3. Gaseous fuels (e.g., natural gas): 20%
4. Flaring gas industrially and at wells: <1%
5. Cement production: 3%
6. Non-fuel hydrocarbons: < 1%
7. The "international bunkers" of shipping and air
transport not included in national inventories: 4%

The US Environmental Protection Agency (EPA) ranks the major greenhouse gas
contributing end-user sectors in the following order: industrial, transportation, residential,
commercial and agricultural. Major sources of an individual's greenhouse gas include home
heating and cooling, electricity consumption, and transportation.

RESULTS AND EFFECTS
U3.1. The Urban Heat Island:
The principal reason for the nighttime warming is that buildings block surface heat from
radiating into the relatively cold night sky. Two other reasons are changes in the thermal
properties of surface materials and lack of evaporation aspiration (for example through lack of
vegetation) in urban areas. Materials commonly used in urban areas for pavement and roofs, such
as concrete and asphalt, have significantly different thermal bulk properties (including heat
capacity and thermal conductivity) and surface recitatives properties than the surrounding rural
areas.
This causes a change in the energy balance of the urban area, often leading to higher
temperatures than surrounding rural areas.[7]

In the last 25 years Dubai has grown by leaps and bounds. Billions of pounds have been pumped into Dubai.
21. The Global Warming & Architecture Part-one- The 20th

U3.2. The Green Land Melting:
Greenland is losing mass at 3% per decade and melting rates have accelerated. Melting in
2004 was occurring at 10 times the rates observed in 2000. Pools of melt water are visible on the
surface each summer and melt water is percolating down through crevasses to lubricate the ice.[8]
[FIG.3.2.]
As the “rivers of ice” speed up, the potential for slippage of large
glaciers from Greenland increases.
U3.3. Current Sea Level Rise:
Current sea level rise has occurred at a mean rate of 1.8 mm per year for the past century,
and more recently, during the satellite altimetry era of sea level measurement, at rates in the
range of 2.9-3.4 ± 0.4-0.6 mm per year from 1993–2010.[9]
Global average sea level has risen between 4 and 8 inches over the last 100 years. Active
summer ice is disappearing faster than expected. There has been widespread retreat of mountain
glaciers during the twentieth century.[9]
Loss of permafrost in Alaska is damaging roads, housing and pipeline structures. Loss of 60 % of
tropical corals is threatening barrier reefs.
Rising sea levels would adversely affect many coastal marshes and wildlife reserves.

IV GLOBALIZATION
U4.1. Globalization & Knowledge Society:
During the last decade, a great deal of news media attention has focused on informing the
world public about scientific findings on global warming (GW). Has learning this sort of
information led the public to become more concerned about GW?
Using data from two surveys of nationally representative samples of adults, among
people who trust scientists to provide reliable information about the environment and among
Democrats and Independents, increased knowledge has been associated with increased concern.
But among people who are skeptical about scientists and among Republicans more knowledge
was generally not associated with greater concern.
UDeveloped Countries & Developing Countries:U
[1]
Understandably the developing countries want the right to economically expand the
fastest way they can, like developed nations have been doing for the past 100 years. Developing
countries face a difficult decision, whether to sacrifice their economic development for
protection against possible ecological problems in the near future.
Many developing countries have neither the resources nor the technology to defend
against rising sea levels, increased incidence and ferocity of tropical storms, and expansion of
tropical diseases. Developing countries face a difficult decision, whether to sacrifice their
economic development for protection against possible ecological problems in the near future.
U4.2. Saving Our Planet:
U4.2.1. Agenda 21:[2]
Agenda 21 is an action plan of the United Nations (UN) related to sustainable
development and was an outcome of the United Nations Conference on Environment and
Development (UNCED) held in Rio de Janeiro, Brazil, in 1992.
It is a comprehensive blueprint of action to be taken globally, nationally and locally by
organizations of the UN, governments, and major groups in every area in which humans directly
affect the environment.
The Commission on Sustainable Development acts as a high level forum on sustainable
development and has acted as preparatory committee for summits and sessions on the
implementation of Agenda 21.
The United Nations Division for Sustainable Development acts as the secretariat to the
Commission and works 'within the context of' Agenda 21. Implementation by member states
remains essentially voluntary.
26. The Global Warming & Architecture Part-two- The 21st
Century
U4.2.2. Kyoto Protocol (2005):[3]
The Kyoto Protocol is a protocol to the United Nations Framework Convention on
Climate Change (UNFCCC or FCCC), aimed at combating global warming. The Protocol was
initially adopted on 11 December 1997 in Kyoto, Japan and entered into force on 16 February
2005.As of November 2009, 187 states have signed and ratified the protocol.[FIG.4.1.]
UObjectives:
Under the Protocol, 37 industrialized countries (called "Annex I countries") commit
themselves to a reduction of four greenhouse gases (GHG), Annex I countries agreed to reduce
their collective greenhouse gas emissions by 5.2% from the 1990 level. Emission limits do not
include emissions by international aviation and shipping, but are in addition to the industrial
gases, chlorofluorocarbons, or CFCs, which are dealt with under the 1987 Montreal Protocol on
Substances that Deplete the Ozone Layer.
U4.3. Green Buildings: U
[4]
Green building is the practice of creating structures and using processes that are
environmentally responsible and resource-efficient throughout a building's life-cycle from sitting
to design, construction, operation, maintenance, renovation and deconstruction. This practice
expands and complements the classical building design concerns of economy, utility, durability,
and comfort. Green building is also known as a sustainable or high performance building.

U5.1. Green Buildings Strategy:U
[5]
Green building brings together a vast array of practices and techniques to reduce and
ultimately eliminate the impacts of buildings on the environment and human health.
It often emphasizes taking advantage of renewable resources, e.g., using sunlight through passive
solar, active solar, and photovoltaic techniques and using plants and trees through green roofs,
rain gardens, and for reduction of rainwater run-off.
Many other techniques, such as using packed gravel or permeable concrete instead of
conventional concrete or asphalt to enhance replenishment of ground water, are used as well.
While the practices, or technologies, employed in green building are constantly evolving and
may differ from region to region, there are fundamental principles that persist from which the
method is derived: [FIG.5.1.]
- Sitting and Structure Design Efficiency,
- Energy Efficiency, Water Efficiency,
- Materials Efficiency,
- Indoor Environmental Quality Enhancement,
- Operations and Maintenance Optimization,
- Waste and Toxics Reduction.
FIG.[5.1.] the Green Buildings Strategy
28. The Global Warming & Architecture Part-two- The 21st
Century
U 5.2. Renewable Energy Generation
U 5.2.1. Solar panels:U
[6]
Active solar devices such as photovoltaic solar panels help to provide sustainable
electricity for any use. Typical efficiencies for commercially available PV panels range from 4%
to 28%. The low efficiency of certain photovoltaic panels can significantly affect the payback
period of their installation. A good rule of thumb for the cost of installing solar panels is roughly
about $4.30/Watt.
U5.2.2. Solar water heating:U
[7]
Solar water heaters-also called solar
domestic hot water systems can be a cost-
effective way to generate hot water for a home.
They can be used in any climate, and the fuel
they use sunshine is free. There are two types of
solar water systems- active and passive. An active
solar collector system will cost approximately
$2,500 to $3,500 installed and produce about 80
to 100 gallons of hot water per day. A passive
system will cost about $1,000 to $2,000 installed
but will have a lower capacity.
Electric-resistance water heaters that are common in homes today have an electrical
demand around 4500 kW·h/year. With the use of solar collectors, the energy use is cut in half.
The up-front cost of installing solar collectors is high, but with the annual energy savings,
payback periods are relatively short.[FIG. 5.3.]

29. The Global Warming & Architecture Part-two- The 21st
Century
U5.2.3. Wind turbines:U
[8]
A wind turbine is a device that converts kinetic energy from the wind into mechanical
energy. Developed for over a millennium, today's wind turbines are manufactured in a range of
vertical and horizontal axis types. The smallest turbines are used for applications such as battery
charging on sailing boats; while large grid-connected arrays of turbines are becoming an
increasingly large source of commercial electric power.[FIG.5.4.]
A small wind turbine can be installed on a roof. Small-scale rooftop wind turbines have been
known to be able to generate power from 10% to up to 25% of the electricity required of a
regular domestic household dwelling.
Turbines for residential scale use are available. They are usually approximately 2 m to 8 m in
diameter and produce electricity at a rate of 900 watts to 10,000 watts at their tested wind speed.
In the United States, residential wind turbines with outputs of 2-10 kW, typically cost
between $12,000 and $55,000 installed ($6 per watt),although there are incentives and rebates
available in 19 states that can reduce the purchase price for homeowners by up to 50 percent, to
($3 per watt).

U5.3. Sustainable materials:U
[9]
Some examples of sustainable building materials include recycled denim or blown-in
fiber glass insulation, sustainably harvested wood, Tress, Linoleum, sheep wool, concrete (high
and ultra high performance roman self-healing concrete), panels made from paper flakes, baked
earth, rammed earth, clay, vermiculite, flax linen, sisal, cork, expanded clay grains, coconut,
wood fiber plates, calcium sand stone, locally obtained stone and rock, and bamboo, which is
one of the strongest and fastest growing woody plants, and non-toxic low-VOC glues and paints.
UWaste management:
The management of waste is a key component in a business. Companies are encouraged
to improve their environmental efficiencies each year. One way to do this is by improving a
company’s waste management with a new recycling service. [FIG.5.5.]-Such as recycling: glass,
food waste, paper and cardboard, plastic bottles etc.
There are a number of concepts about waste management which vary in their usage between
countries or regions. Some of the most general, widely used concepts include: [FIG.5.6.]
- Waste hierarchy
- Extended producer responsibility
- Polluter pays principle

UWHITE ROOF:U
A physicist at the Lawrence Berkeley lab just released a study showing
that the average American 1,000-square-foot white roof could offset 10
metric tons of CO2. According to his data, roofs constitute 20 to 25 % of
urban surfaces, while pavement is about 40 %. Therefore, if all of those
surfaces were switched to a reflective material (or color) in the 100 largest
urban areas in America, his calculations show, this would offset 44 metric
gigatons of CO2. [FIG.5.7.]
UGREEN-SCREEN:
Green-screen is a type of metal structure that can be attached to
existing walls or used to create freestanding growing walls. By
integrating more trees and photosynthesizing plants within the
fabric of our existing cities, we harness the power of plants to
absorb carbon from the atmosphere. The surface area of buildings
multiplies the ground footprint of the city many times over,
making vertical gardening and the integration of growing walls
into our buildings an interesting practical solution. The roofs-cape
of most cities is an area that is often forgotten but that could
easily be used for the application of green technologies beneficial to all.[FIG. 5.8.]
UWIND-BELTS AND GREEN ROOF:
Wind belts are a recent technology which harnesses the power of the
wind to generate electricity. They are relatively inexpensive and
suitable for both developed and developing countries and are the
first wind technology not to employ turbines ,Wind-belts could be
used on the facades and roofs of existing buildings as a sculptural
element, taking advantage of the building envelope as an available
surface upon which to attach. Trees may be planted on the roof by
using either planters or by using a new Japanese soil substitute,
which is much lighter than earth.[FIG. 5.9.]
UROOF POND:U
Roof ponds can be used for cooling in areas that are warm and not very
humid. This technology has a lot of potential, but has been underused to
date because of a fear of leakage on the part of architects and clients,
however, if properly detailed it is a promising strategy and can help to
reduce the heat island effect in cities. Insulating panels cover the roof and
are opened during the day in the winter to absorb the heat of the sun, and
at night, the panels are closed, allowing heat to radiate to the building’s
interior. In the summer, the process is reversed.[FIG.5.10.]

UROOF SPRAY:U
This is another method for cooling which could be employed
in a retrofit of existing buildings. It can be used in
combination with the roof pond, or independently with the
water being stored in a tank. Here water is cooled by spray at
night, via evaporation and night sky radiation, and then stored
for use during the day in the building’s cooling system (Stein
& Reynolds, 379-80).[FIG.5.11.]
UWATER WALL, AND SOLAR PIPE:U
It is well known that electricity can be generated from fast
moving water. Here, we propose that a water wall be added
to a blank facade on an existing building as a means of
generating electricity. Water can be collected via a system of
gutters on the building, and then can be piped and recycled to
generate the necessary flow. This water can also be used to
flush toilets and for other non-potable applications. In
addition, the water provides cooling to the building’s
inhabitants. The roof in this scheme is envisioned as a space
in which the entire surface area is covered by solar coils.[FIG.5.12.]

U6.1. Nanotechnology for Green Building:
U6.1.1. Nanotechnology:U
[11]
Nanotechnology, the manipulation of matter at the molecular scale, is bringing new materials
and new possibilities to industries as diverse as electronics, medicine, energy and aeronautics.
Our ability to design new materials from the bottom up is impacting the building industry as
well. New materials and products based on nanotechnology can be found in building
insulation, coatings, and solar technologies. Work now underway in nanotech labs will soon
result in new products for lighting, structures, and energy.[FIG.6.1.]
Globally, nanotechnologies are expected to reduce carbon emissions in three main areas:
1) Transportation.
2) Improved insulation in residential and commercial buildings.
3) Generation of renewable photovoltaic energy.
U6.1.2. Nano-products at the Construction Site:U
[12]
The market for green building materials and technologies will of course be determined more by
market pull--the needs of architects, owners and contractors--than by the technological push of
new nanomaterials discovered and developed in the laboratory. But the convergence of green
building demands and green nanotechnology capabilities over the next 5-10 years appears very
strong.
It suggests some categories of nanotechnology for green building: [FIG.6.2.]
- Insulation
- Coatings
- Adhesives
- Solar energy
- Lighting
- Air and water filtration
- Structural materials
- Non-structural materials

U6.2. The Zero Carbon City: U
[13]
To become a zero carbon city, an established modern city must collectively reduce
emissions of greenhouse gases to zero and all practices that emit greenhouse gases must cease.
Also, renewable energy must supersede other non-renewable energy sources and become the sole
source of energy, so a zero-carbon city is a renewable-energy-economy city.[FIG.6.3.]

U6.3. The Energy Island: U
[14]
A single 250-megawatt OTEC plant can meet the energy demands of 250,000 households
and provide 600 million liters of drinkable water each day. Any surplus water can be used to
support local agriculture and industry.[FIG.6.4]
One strategy being used to alleviate this crisis involves compact, floating "energy islands".
These combine offshore power generation with desalination plants.

38. The Global Warming & Architecture Our Responsibility
Our Responsibility
To accomplish these challenges there are some URecommendationsU:
1-According to" UDohalandU " conference 10 THINGS WHICH MAKE A DIFFERENCE:
- Reduce garbage – approximately 44 percent of the world’s wastage disposal comes from
the Arab world.
- Reduce paper usage currently - 90 % of the world’s paper is manufactured from wood pulp.
- Use energy efficient light bulbs and save 150 pounds of CO2 per year.
- Turn off electrical devices and save 0.9 tons of CO2 annually.
- Car pool whenever possible.
- Plant a tree – it will absorb one ton of CO2 per year.
- Adjust your thermostat and save about 2,000 pounds of CO2 per year.
- Buy organic / Conserve water / Shop smart – avoid plastic and too much packaging.
2- The AUcademy of Architectural DesignU is supported on:
- Add to all design studio projects the following requirement:
"All design projects should engage the environment in a way that dramatically
reduces or eliminates the need for fossil fuel."
- Achieve complete ecological literacy in design education, including the following areas
of study:
Design / studio - history / theory - materials / technology - structures /
construction - professional practice / ethics
- Achieve a carbon-neutral design school campus.
3-UGovernmentsU can take several steps to reduce the threat of global warming:
- First and foremost, the United States and other industrial nations must use less of the
fossil fuels.
- Other steps, such as transferring technology to developing countries, preserving forests,
decreasing atmospheric methane, and slowing down population growth, are also
important.
39. The Global Warming & Architecture General Conclusion
General Conclusion
1- Global warming is the increase in the average temperature of Earth's near-surface air and
oceans since the mid-20th century and its projected continuation.
2- Addressing global climate change is a paramount challenge of the 21st Century. Since the
beginning of the industrial revolution, atmospheric concentrations of carbon dioxide (CO2),
the chief heat-trapping greenhouse gas, have risen 35 % , from about 280 to 377 parts per
million (ppm) , This increase is primarily from the burning of fossil fuels and from
deforestation.
3- There is no doubt that climate will continue to change throughout the 21st century and
beyond, but there are still important questions regarding how large and how fast these
changes will be, and what effects they will have in different regions.
4- Buildings alone are responsible for 15% of all human GHG emissions. It is the industrial
sector which contributes the most to Climate Change. But according to the IPCC, it is also
the sector which presents the most cost effective opportunities for GHG reductions.
5- Sustainability is the key to a survivable future on Earth: we must find ways to conserve our
resources, reuse the materials we have extracted from the Earth, and turn to renewable
resources for energy. Perpetual economic growth is physically impossible on a planet with
finite resources.
6- Technological solutions to both emission reductions and adaptation to climate change have
occurred at a faster and faster rate through the 21st century, producing a global developed
society unrecognizable from those a hundred years previous.
7- The next five to ten years will see a boom in nanotechnology for green building. Current
nanomaterials and nano-products show demonstrable environmental improvements
including energy savings and reduced reliance on non-renewable resources, as well as
reduced waste, toxicity and carbon emissions.
