Simple efficiency measures can reduce the amount of energy needed for heating, cooling, hot water, appliances, and lighting. They are applicable to all building sizes and types, and can save homeowners and renters money on energy bills. A home energy assessment or energy audit – during which an energy specialist visits your home – is available through Mass Save®.

Opportunities to reduce energy use include:

  • Instant Savings Measures or Products: Immediately save energy upon installation (e.g., LED lightbulbs, advanced power strips, low-flow showerheads, faucet aerators, and efficient thermostats, etc.)
  • Weatherization: Improve the building envelope and reduce energy loss by sealing air leaks (e.g., around doors, windows, or in the attic) or adding wall or attic insulation.
  • Equipment and Appliances: Replace inefficient equipment to save money and energy on heating, ventilation, and air conditioning equipment as well as hot water equipment and other appliances (e.g. clothes washers, refrigerators, etc.)

To meet customers’ unique needs, program options will vary based on building and occupant type. Learn more about program offerings applicable to you below.

Renters/Tenants

Benefits of Energy Efficiency:

  • Energy efficiency can help renters that pay their own utility bills save money on energy. Utility bill savings can come from “instant-saving” energy efficient products installed “in-unit”, such as LED light bulbs, advanced power strips, and efficient thermostats, as well as from “whole building” upgrades that must be authorized by the landlord such as weatherization and equipment/appliance replacement.
  • Energy efficiency can also help renters by improving comfort and indoor air quality. Certain energy efficiency improvements, such as weatherization and heating/cooling equipment upgrades, help make indoor space more comfortable and improve indoor air quality.
  • Reduced energy costs associated with energy efficiency may allow landlords to make other needed building improvements.

Most energy efficiency technologies require landlord permission in order to implement them.  Renters can maximize benefits from energy efficiency by referring their landlord to Mass Save or other applicable efficiency programs.

Energy efficiency programs offerings are based on the number of units in the building. Select the appropriate housing type below to learn more about offerings that may be available, including special programs that cover the full cost of recommended efficiency improvement based on your household income:
