This document discusses green building and indoor air quality. It notes that buildings account for a large percentage of energy, water and carbon emissions in the US. Building green provides healthier homes that cost less to operate. It also summarizes factors that affect indoor air quality like sources of pollution from building materials and HVAC systems. Finally, it discusses strategies for improving indoor air quality through design, maintenance and administrative controls.

3. When you build green,
1. You take affordable housing to the next level of
performance.
2. You give owners and residents more comfortable
homes that cost less to operate, last longer, and
keep occupants healthy.
3. You keep current with leading building techniques
and gain valuable experience with a team
approach that improves design and construction.
4. And of course, you help improve our environment
as your buildings become more efficient, use less
resources, and reduce their impact.
