HERS Rating Massachusetts | Stretch Energy Code Compliance

If you need a HERS Rating in Massachusetts, Home Energy Efficiency Consultants provides certified energy modeling, blower door testing, duct leakage testing, and final HERS certification for residential construction projects.

Our company works with builders, developers, and homeowners across the state to ensure compliance with the Massachusetts Stretch Energy Code and other energy efficiency requirements.

Energy modeling and field verification are commonly required to demonstrate compliance with energy standards administered by the Massachusetts Department of Energy Resources.

What Is a HERS Rating?

A Home Energy Rating System (HERS) Index measures the energy efficiency of a home compared to a reference home built to standard building code.

The rating system follows national standards developed by RESNET.

Typical HERS score ranges include:

• 100 – Standard new home built to minimum building code

• 70–55 – Energy-efficient home

• 45–42 – Common target for Massachusetts Stretch Energy Code compliance

• 0 – Net Zero Energy home

HERS ratings are widely used for energy code compliance, high-performance home construction, and Mass Save rebate qualification.

Massachusetts Stretch Energy Code Requirements

Many municipalities across Massachusetts follow the Stretch Energy Code, which requires homes to meet higher energy performance standards than the base building code.

The performance path often requires:

• Energy modeling during the design phase

• Verified insulation installation

• Blower door testing

• Mechanical system verification

• Final HERS certification

Working with a certified HERS rater early in the design process helps ensure projects meet code requirements and pass final inspections.

Mass Save Rebates and Energy Incentives

High-efficiency homes across Massachusetts may qualify for rebates through the Mass Save program.

Mass Save incentives are available for upgrades such as:

• Heat pump heating and cooling systems

• Heat pump water heaters

• Energy Star appliances

• High-performance insulation upgrades

These programs help homeowners reduce the cost of installing energy-efficient equipment.

HERS Rating Services in Massachusetts

Home Energy Efficiency Consultants provides complete energy compliance services including:

Energy Modeling

Energy modeling helps determine insulation levels, window performance, and HVAC equipment needed to meet the target HERS score.

Blower Door Testing

Blower door testing measures air leakage in the building envelope to confirm compliance with energy code air-sealing requirements.

Duct Leakage Testing

Duct testing ensures HVAC systems are sealed and operating efficiently.

Insulation Inspections

Field inspections verify insulation installation before drywall to ensure the building envelope matches the approved energy model.

Mechanical System Verification

Heat pumps, ERVs, and heat pump water heaters must match the equipment used in the energy model.

Final HERS Certification

After construction is complete, we perform final testing and provide the official HERS Index rating required for building code compliance.
