Solar photovoltaic and thermal systems are far from the only way to save energy at home. Green building techniques are just as effective, and the third annual Green Buildings Open House is scheduled in collaboration with the American Solar Energy Society's National Solar Tour on Saturday, October 2, from 10 a.m. to 4 p.m.

Over 350 green homes, office buildings, schools, and wind farms from Maine to Washington, DC will be open to the public. Northeast Sustainable Energy Association (NESEA) organized the tour, and the Massachusetts Technology Collaborative Renewable Energy Trust is a major sponsor of the event. Visitors can qualify to win door prizes from Zoar Outdoors, Eastern Mountain Sports, and Maple Hill Farm B&B.
