Although you’ll have to wait until 2009 to find Helios Monroe on the tour, you can visit over fifty solar and environmentally friendly homes in DC, Maryland and Virginia this weekend.

The 2008 Solar Tour will be held on October 4th and 5th from 11:00 am to 5:00 pm. Homeowners and guides will be on hand to answer your questions and give you hints on how to go solar. Details on the tour here.

In conjunction with this event, the Takoma Park Green Homes Tour will be held on Sunday the 5th. This tour will include small-scale energy efficiency retrofits, green additions and new construction.  You can also see gardens with bio-retention systems, rain gardens, wildlife habitats and native plants.
