See the elements of a green home up close from 1 to 3 p.m., May 5, at Green House Fest. Talk with Brookline homeowners that have lived with and benefited from energy efficient and fossil fuel-free features such as solar panels, heat pumps, electric cars, electric water heaters and solar hot water. A print map along with an online version will direct individuals to the right stops in three easily walkable neighborhood clusters.

Sponsored by Mothers Out Front, the group believes that an information exchange among neighbors can be a powerful tool for change. Join them to fight climate change and protect our children’s future.

Cost: Free. Location: See website for Brookline location. For more information, call 617-429-7139 or visit GreenHouseFest.org.
