Multi-Family Assistance

855-472-0318
If you are the owner or operator of a residential multi-family facility with five (5) or more units on the property, energy efficiency should be a key part of your business plan. Regardless of your income, rate code, or whether the building currently exists or is scheduled for construction, you may be eligible for programs for reducing your facility’s energy usage.

CET offers Multi-Family Energy Assessments for facilities in western Massachusetts to identify cost-effective energy efficiency improvement opportunities.

We offer a range of services to the farming community to reduce energy use and produce renewable energy that focus on bringing projects from concept to completion.

The MA Farm Energy Program (MFEP) is a joint project of CET and the Massachusetts Department of Agricultural Resources (MDAR).

CET performed my first home energy audit in the 1970s, and their programs have been saving me money and reducing my environmental impact ever since.
