Commercial Energy Recovery Ventilators

Receive rebates to keep indoor air fresh and comfortable year-round.

Upgrade to a more efficient ventilation system to improve your indoor air quality needs, with greater energy savings and improved comfort.

Commercial Energy Recovery Ventilators (ERVs) help bring fresh air into a building without wasting energy. They remove the stale indoor air and replace it with clean outdoor air, while using the outgoing air to warm or cool the incoming air.

Businesses are eligible for incentives for ERVs or Heating Recovery Ventilators (HRVs) when the system meets the minimum efficiency requirement of recovering at least 75% of energy in heating and/or cooling conditions (see specific efficiency requirements below).

Fresh air in, energy saved, comfort assured. ERVs keep every indoor space fresher and more energy efficient.

Preapproval is recommended for all participants. For customers where Cape Light Compact or National Grid is the Program Sponsor, projects with a combined total rated supply airflow of 60,000 CFM or greater require pre-approval. For customers where Berkshire Gas, Eversource, Liberty, or Unitil is the Program Sponsor, all projects require pre-approval. Contact your Sponsor to receive pre-approval as required.

 

Equipment Type1 Minimum Efficiency Requirements Rebate ($/CFM)1
Energy Recovery Ventilator (ERV) Enthalpy recovery ratio (ERR) of at least 75% at both cooling and heating design conditions $1.50
 Heat Recovery Ventilator (HRV)
(does not recover humidity/enthalpy)
Sensible energy recovery ratio (SERR) of at least 75% at heating design conditions $1.00


1
CFM measured as total rated supply airflow. Total rebate amount shall not exceed installed costs (inclusive of both equipment and installation).

  1. Determine Your ERV Needs
    Work with a licensed HVAC contractor to determine which equipment is right for your business and eligible for a rebate.
  2. Complete pre-approval as required*
    Preapproval is recommended for all participants. For customers where Cape Light Compact or National Grid is the Program Sponsor, projects with a combined total rated supply airflow of 60,000 CFM or greater require pre-approval. For customers where Berkshire Gas, Eversource, Liberty, or Unitil is the Program Sponsor, all projects require pre-approval.
  3. Apply for a rebate
    Upon completion of installation, apply for a rebate by submitting all required documentation to your Mass Save Sponsor. Find your Mass Save Sponsor contact details here.

    For equipment displacing natural gas heating, you should contact your Gas Sponsor, otherwise, you should contact your Electric Sponsor. See detailed eligibility requirements.

*Contact your Sponsor before installation if:

  • The proposed project includes a combined total rated supply airflow of more than 60,000 CFM. For Berkshire Gas, Eversource, Liberty, or Unitil customers, all projects require pre-approval.
  • The proposed project is for a new building being constructed or a major renovation (visit MassSave.com/CINCMR).
  • The proposed project is for a multifamily building, as rebate eligibility depends on facility metering.
  • The equipment is being installed to recover energy from exhaust air at an indoor pool, exhaust air at a laboratory, or from Class 4 exhaust air as defined by ASHRAE 62.1.
  • You or your contractor has questions about project eligibility.

Please review rebate form for detailed eligibility requirements.

  • Equipment must be installed in Massachusetts by a licensed contractor.
  • Equipment displacing natural gas eligible only for commercial or industrial metered customers receiving natural gas service from a Sponsor of Mass Save.
  • Equipment displacing oil, propane, or electric heat eligible only for commercial or industrial metered customers receiving electric service from a Sponsor of Mass Save.
  • When equipment is installed for a project that includes concurrently replacing an existing heating system with an electric heat pump, for determining eligibility, the heating fuel displaced is that of the previous heating system. For example, if energy recovery is installed alongside an electric heat pump which displaces a natural gas heating system, the energy recovery is eligible for a rebate only if the natural gas service was from a commercial or industrial metered gas account provided by a Sponsor of Mass Save.
  • Equipment is new and installed to recover heat from an existing oil, propane, natural gas, electric resistance, or electric heat pump heating system.
  • Equipment rebates are limited to air-to-air recovery using fixed-core or wheel-type energy recovery equipment; all equipment must be AHRI certified.
  • Equipment seeking to qualify for an Energy Recovery Ventilator (ERV) rebate must provide an enthalpy recovery ratio (ERR) of at least 75% at cooling and heating design conditions when tested in accordance with AHRI Standard 1060.
  • Equipment seeking to qualify for a Heating Recovery Ventilator (HRV) rebate must meet a sensible energy recovery ratio (SERR) of at least 75% at heating design conditions when tested in accordance with AHRI Standard 1060.
  • Combined total rated supply airflow rate of all energy/heat recovery equipment included in a project must not exceed 60,000 cubic feet per minute (CFM).
  • Equipment that has already received an incentive from a Sponsor of Mass Save is not eligible for a rebate.
  • Equipment that is being installed in a new construction project is not eligible for a rebate.
