We have been building since 1972 with the idea that each home we build can be better than the last. As you
think about the home you plan to build for your family, here’s some food for thought...
• The heating, cooling and operation of U.S. buildings accounts for more than 40% of CO 2
emissions.

• Research indicates that we spend approximately 90% of our time indoors. A growing body of scientific
evidence indicates the air within homes can be more seriously polluted than outdoor air.

• At thoughtforms, we are building homes that generate more energy than they use.
• We test air quality, not only to ensure we deliver healthy homes, but to help families understand how daily
living affects indoor air quality.
What kind of home will you build for your family, our community and the environment that supports us all?
It’s what we build next that matters.
