Savings for Multi-Family Units

If you are the owner or operator of a residential multi-family property with 5 or more units, 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 building’s energy usage.
Cape Light Compact offers Multi-Family Energy Assessments that identify cost-effective energy efficiency improvement or replacement opportunities. Utilizing a “whole building” approach, we focus on your building’s thermal envelope with insulation and air sealing, as well as lighting and mechanical systems. We will also assess the in-unit savings potential for your tenants.



Eligible multi-family facilities are defined as residential facilities with five or more dwelling units on the property, or buildings with income-eligible residents living in multi-family facilities with five or more units owned or operated by a non-profit entity, public housing authority, or where at least 50% of the tenants qualify as low-income. These facilities would qualify under the Mass Save® Low Income Multi-Family Program.
