All American Homes recently kicked off The Living Zero Home Tour in conjunction with the U.S. Department of Energy.

• Traveling home features interactive and educational displays designed to be informative and fun
• Purpose is to showcase energy efficient, commercially available products to hundreds of thousands of consumers

The tour began in Chicago on July 1, 2009. It will travel to 15 locations (PDF) through the end of November.

The company has a page describing some of the benefits of systems-built (modular) housing:

Each custom-built home is made ... in a controlled environment. Your home is protected from weather and vandalism during the construction process. It arrives to your site about 70 to 85% complete, and in most cases is set on its permanent foundation and locked the same day.

... controlled construction saves time and money. Systems-built home construction allows you to plan, predict and control costs through better scheduling and more accurate planning.
