HERS Ratings in Boston, Massachusetts

Why They Matter for Stretch Code Compliance & Mass Save Rebates

If you’re building, renovating, or adding onto a home in Boston, Massachusetts, a HERS Rating is one of the most important steps to ensure your project passes energy code and qualifies for Mass Save rebates.

A HERS Rating (Home Energy Rating System) — also known in the building code as an ERI (Energy Rating Index) score — is a third-party energy performance evaluation completed by a certified HERS Rater. In Boston and throughout Massachusetts, HERS ratings are commonly used to demonstrate compliance with the state’s energy code pathways and to support rebate eligibility through Mass Save programs.

What Is a HERS Rating?

A HERS Rating measures the overall energy efficiency of a home. It evaluates:

Insulation levels
Air sealing performance
Windows and doors (U-factor & SHGC)
Heating and cooling systems
Ventilation systems (ERV/HRV)
Water heating equipment
Duct leakage (if applicable)

The rating includes field verification such as:

Blower door testing
Duct leakage testing (when required)
Insulation inspections
Equipment verification

This process creates official documentation used for building department approval and incentive programs.

Why HERS Ratings Are Important for Massachusetts Stretch Code

Massachusetts has multiple energy code pathways, including:

Base Energy Code
Stretch Code
Specialized (Opt-In) Code

Many municipalities, including Boston, follow enhanced energy requirements. One of the most common compliance paths is the ERI/HERS performance pathway, where your project must meet a specific energy score.

Here’s Why That Matters:

1. Clear Performance Target

Instead of only checking individual components, the ERI/HERS pathway evaluates total home performance. This allows flexibility — you can improve insulation, air sealing, HVAC efficiency, or windows to achieve the required score.

2. Prevent Final Inspection Failures

Without midpoint inspections and testing, projects often fail final blower door tests or fall short of the required score. A HERS Rater ensures issues are corrected before final inspection.

3. Required Documentation

Building departments often require official HERS documentation to verify compliance under performance-based energy code paths.

4. Higher Quality Construction

Homes built to meet HERS standards are typically:

More comfortable
More energy efficient
Quieter
Less prone to moisture issues

Why HERS Ratings Are Critical for Mass Save Rebates

Mass Save programs for new construction and renovations often require involvement from a certified HERS Rater.

HERS ratings help:

Optimize the home for higher rebate tiers
Verify insulation and air sealing upgrades
Confirm eligible HVAC and water heating equipment
Document performance improvements
Support incentive applications

New Construction

Mass Save new construction programs are structured around working with a HERS Rater to verify compliance and maximize rebates.

Renovations & Additions

Renovation and addition projects can qualify for incentives when improvements are verified and documented properly. HERS involvement ensures all requirements are met.

Always confirm eligibility with your participating utility (National Grid or Eversource) for your specific project type.

Our HERS Process for Boston Projects

1. Plan Review & Preliminary Report

We review architectural plans, insulation specs, windows, HVAC equipment, ventilation systems, and water heating to establish your target score.

2. Midpoint Inspection

We perform an insulation inspection and verify air sealing details before walls are closed. Optional midpoint blower door or duct testing can prevent final failures.

3. Final Testing & Certification

We complete blower door testing, duct testing (if required), and verify all installed equipment. Final documentation is provided for code compliance and rebate submission.

When Should You Hire a HERS Rater?

The best time to involve a HERS Rater is during the design or permitting stage. Early involvement prevents costly changes later and ensures all windows, HVAC systems, and ventilation equipment comply before ordering.
