As green living becomes more popular, more U.S. communities are organizing tours of eco-friendly homes. For the 20th year, Washington, DC-area homes will be open for the public this weekend.

The 20th Annual Washington DC Solar Homes Tour is October 2-3, 2010. Explore more than 100 green homes in the area, including some that are currently on the market. The tour will showcase a remarkable variety of solar design, technology, and sustainable living concepts.

Each touring day has a variety of unique educational opportunities to put a true environmental “spin” on your experience. All the solar tour homes will be listed in your tour guide. Your tour guide will be both your map and “passport” to gain entry to the sites on the tour. The guide will have descriptions, features and directions to each home as well as helpful information on installing a system in your home.

Pick up tour guides throughout the area at these locations, or download a copy online here.
