This first section is meant to provide a high-level understanding of the issues involved in

sustainable, high-performance building design.

Whats the problem?Why are buildings so important?How do building designers start to address these issues?

Let's start by understanding more about the environmental issues that make this work so

important...

A s ice core records from A ntarctica show that changes in carbon dioxide concentration

track closely w ith changes in temperature (red). C arbon dioxide levels are now higher

any time during the past 650,000 yea rs. (CRED IT : Marian Koshland Science Museum,

Environmental Issues & Building DesignAccording to the scientific community, climate change is happening and i

effects will have severe consequences for our society and environment.

Reducing energy use in buildings is one of the most important ways to r

humans overall environmental impact.

Nearly unanimous scientific consensus has

established that climate change is occurring

as a result of human activity. Mathematical

models of global climate change have

linked a human-driven increase in GHGs to

an increase in global temperatures

(especially in the past 250 years, since the

industrial revolution). The primary source

of this increase in GHCs has been attributed

to the emissions generated by the use of

fossil fuel-based energy.

Climate change has been linked observable

disturbances such as the loss of mountain

glaciers and ice cover on the Earths polar

regions, changes in the timing of the spring

bud-break, and an increase in the frequency and intensity of extreme weather events such as cold waves, heat w

large storms, hurricanes and tornadoes, floods, and droughts.

Climate scientists have theorized that human civilization is in danger of crossing a threshold or tipping point tha

lead to more radical changes in the global climate, and that could accelerate the onset of either a newhotter an

age similar to the Earths environment beforethe appearance of human beings, or a new ice age. (Intergovernm

Panel on Climate Change, IPCC Fourth Assessment Report [AR4]).

Scientific estimates place the window of opportunity for reversing this trend in the very near termaccording to s

briefly as over the next ten years. After that, the global climate may change irreversibly, and humans will just ha

adapt.

In many arenas of implementing real practical change, architects, engineers, and builders are the only ones with

and resources that provide real, practical, cost-effective, and inspiring solutions.
