WHY SUSTAINABLE BUILDINGS? Sustainable
building merges sound, environmentally responsible practices
to look at the environmental,
economic
and social effects
of a built project as a whole.
SUSTAINABILITY: “Meeting the needs of the present without compromising
the ability of future generations to meet their own needs” -
including nature
DESIGN: Designers include all those who change the environment
with the inspiration of human creativity. Design implies the
conception and realization of human needs and desires.
DESIGN FOR
SUSTAINABILITY: Designing for sustainability
requires awareness of the short and long-term consequences of
any kind of transformation of the environment.
The design, construction, and maintenance of buildings has a tremendous
impact on our environment and our natural resources. There are
more than 76 million residential buildings and nearly 5
million commercial buildings in the U.S. today. These buildings
together
use one-third of all the energy consumed in the U.S., and two-thirds
of all electricity.
By the year
2010, another 38 million buildings are expected to be constructed.
The challenge
will be to build
them smart, so they use a minimum of nonrenewable energy, produce
a minimum of pollution, and cost a minimum of energy dollars,
while increasing the comfort, health, and safety of the people
who live
and work in them -Smart

Buildings consume or are responsible for:
| 40% of the world's
total energy use, |
| 30% of raw materials
consumption, |
| 25% of timber harvest, |
| 35%
of the world’s
CO2 emissions, |
| 16%
of fresh water withdrawal, |
| 40% of municipal
solid waste destined for local landfills, |
| 50% of ozone-depleting
CFCs still in use |
Structures also affect watersheds, habitat, air quality, and
community transportation patterns. (Source:
