What is ener-G-save?

Ener-G-save is the brainchild of Harold Grinspoon, a Longmeadow based philanthropist who for more than 2 decades has supported varied educational initiatives, as well as young entrepreneurs and regional farmers. More on Harold Grinspoon and his work here.

ener-G-save’s community based programs local energy conservation as an important lever to help people spend less on energy while reducing greenhouse gas emissions.

Collaborating with towns, grassroots groups, businesses, faith communities, and contractors we help residents navigate and take full advantage of existing utility incentives for energy efficiency.

Our Cooler Communities school grant program leverages classrooms’ curriculum work on climate change and energy to reduce the carbon pollution a community generates.  More about Cooler Communities fairs and the program is here.

Early History:

In 2016 Harold Grinspoon learned about a newly-developed thermal imaging technology that can identify energy leaks quickly and cost-effectively. He founded the Harold Grinspoon Charitable Foundation Energy LLC (short: Ener-G-save) and decided to make use of this thermal imaging technology to educate and inspire Pioneer Valley homeowners to save on energy.

The Foundation hired a company called Essess to collect thermal imaging data on 100,000 homes in the Pioneer Valley, using cars with roof-mounted thermal imaging cameras.

The data was analyzed to determine which Pioneer Valley homes stand to benefit the most from energy-saving retrofits, such as insulating walls and attics, air sealing windows, doors, foundations, and soffits, and replacing old heating and cooling equipment.

In partnership with 10 Pioneer Valley towns, Ener-G-save then sent individualized letters to homeowners whose homes were identified as the most promising for energy efficiency improvements. These letters include the thermal image of each homeowner’s house.

Ener-g-save is no longer providing these images, although some contractors use thermal cameras to check spots in the home and some towns are still using them to analyze their building stock’s potential for energy savings.

During our pilot year, ener-G-save reached over 1,600 homes.
