HEET is a Cambridge-based group that organizes energy-upgrade work parties in the buildings of nonprofits (such as churches, food pantries and preschools).
At the parties, HEET has team leaders teach volunteers hands-on skills in energy efficiency, while they work to make the building more efficient. Typical work items include decreasing the draftiness of a building and installing electricity- and water-saving measures. After the work is finished, the team shares food and celebrates.
An online survey showed over 70% of HEET’s volunteers use their new skills on their own home. Working with sister groups, HEET has trained over 2,000 volunteers in 150 buildings since 2009.
