Sustainability, green building, going green—
you have almost certainly heard these terms used
frequently. Surprisingly, many people do not
have a clear understanding of their meanings.
Most of us are aware that our current lifestyles
have had unintended negative consequences on
the environment. We are beginning to realize that
practices that harm the environment, along with
the depletion of natural resources, will have a
long-term effect on our ability to survive on this
planet. Sustainability is a positive response to this
problem. It involves people who are looking for
ways to reduce our “footprint,” or impact on the
environment, and help preserve the Earth and its
resources for future generations. See Figure 11-1.
This chapter explains the concepts of sustainabil-
ity and green building as they apply to residential
architecture and construction.
