Published: May 2026 | HERS ScoreEnergy EfficiencyMassachusetts Builders Under the MA Stretch Code, new residential construction must achieve a HERS score of 55 or below. If your energy model is coming in too high, here are the most effective strategies to improve your HERS score. What Is a Good HERS Score in Massachusetts? Under the MA Stretch Code, the maximum allowable HERS score is 55. A typical new home built to minimum code scores around 100. An Energy Star certified home typically scores 55–75. Net-zero homes score 0 or below. Highest-Impact Improvements 1. Air Sealing (Biggest Bang for Buck) Improving air tightness from 5.0 ACH50 to 2.0 ACH50 can drop your HERS score by 5–10 points. Focus on attic bypasses, top plates, band joists, electrical penetrations, and plumbing penetrations. Air sealing is typically the most cost-effective way to improve both HERS score and blower door results simultaneously. 2. Insulation Upgrades Adding insulation above code minimums — especially in the attic and walls — can significantly reduce the HERS score. Continuous exterior insulation (ci) is highly effective for wall assemblies. Spray foam in the attic and rim joist provides both insulation and air sealing value. 3. High-Efficiency HVAC Equipment Upgrading from a standard 80% furnace and 13 SEER AC to a 96%+ furnace and 16+ SEER AC (or heat pump) can drop the HERS score by 5–15 points depending on the home’s mechanical load. Cold-climate heat pumps have become increasingly popular in Massachusetts due to their very high HERS improvement and Mass Save incentives. 4. Windows and Doors Specifying triple-pane or high-performance double-pane windows (U-factor 0.25 or below) improves the HERS score, especially in homes with significant glazing area. 5. Mechanical Ventilation Switching from exhaust-only to balanced ventilation (ERV or HRV) improves indoor air quality and can modestly improve the HERS score by reducing the energy penalty of ventilation. Pro Tip: Work with your HERS Rater during the design phase, not after construction. Early energy modeling lets you evaluate these tradeoffs before they’re built in, when changes are cheap.

Published: May 2026 | MA Stretch CodeMunicipalitiesMassachusetts The Massachusetts Stretch Code has been adopted by over 300 cities and towns across the state. If you’re building in Massachusetts, you need to know whether your municipality requires it — and what that means for your project. Which Cities Require the MA Stretch Code? As of 2026, more than 300 Massachusetts municipalities have adopted the Stretch Code, including all of the state’s major cities and most suburban communities. Some of the largest Stretch Code municipalities include: Boston, Cambridge, Newton, Brookline, Somerville, Quincy, Worcester, Springfield, Lowell, Framingham, Brockton, Taunton, Plymouth, Barnstable, and hundreds more. Check with your local building department to confirm whether the Stretch Code applies to your specific project. Requirements can vary by project type and date of permit application. What Are the Requirements? HERS Index score of 55 or below Blower door test result of 3.0 ACH50 or less Duct leakage test meeting Stretch Code limits All testing performed by a RESNET-certified HERS Rater Certified compliance documentation for the building department What If My City Hasn’t Adopted the Stretch Code? If your municipality is on the base energy code rather than the Stretch Code, you still need to comply with the base Massachusetts energy code (IECC 2021 as adopted by Massachusetts). A HERS Rating may still be required or beneficial for Mass Save incentives and green building certifications even without the Stretch Code. Stretch Code Adoption Is Growing Massachusetts is moving toward making the Stretch Code the baseline for all municipalities. Builders and developers working in multiple cities should be prepared to comply with Stretch Code requirements across all their projects.

Published: May 2026 | HERS RatingEnergy StarMassachusetts Massachusetts builders often ask: do I need a HERS Rating, Energy Star certification, or both? While they’re closely related, they serve different purposes and have different requirements. What Is a HERS Rating? A HERS (Home Energy Rating System) Rating is a standardized measurement of a home’s energy efficiency, developed by RESNET. It produces a numerical HERS Index score — lower is more efficient. HERS Ratings are required for MA Stretch Code compliance and Mass Save programs in Massachusetts. What Is Energy Star Certification? Energy Star Certified Homes is a federal program run by the EPA that certifies homes meeting specific energy efficiency requirements. Energy Star Version 3.2 (current) requires homes to achieve a HERS score that meets the program’s requirements plus pass additional verification checklists covering HVAC, insulation, and windows. Key Differences Purpose: HERS is a measurement tool; Energy Star is a certification program. Requirement in MA: HERS Rating is required for MA Stretch Code; Energy Star is optional but provides additional marketing value and may qualify for federal tax credits. Cost: Adding Energy Star certification to a HERS Rating adds minimal cost since most of the work overlaps. Federal Tax Credits: Energy Star certified homes may qualify for the 45L New Energy Efficient Home Credit ($2,500–$5,000). Can You Get Both at the Same Time? Yes — and you should. Since a HERS Rating is already required for MA Stretch Code compliance, adding Energy Star certification requires only minor additional documentation during the same inspection visit. HERS Rating Company can provide combined HERS Rating + Energy Star certification services for Massachusetts builders. Bottom line: Get the HERS Rating for Stretch Code compliance. Add Energy Star for federal tax credits and marketing differentiation — the incremental cost is small relative to the benefits.

Published: May 2026 | Duct LeakageMassachusettsEnergy Testing Duct leakage testing is a required component of HERS Ratings and MA Stretch Code compliance in Massachusetts — but many builders don’t fully understand what’s being tested or how to ensure their duct systems pass. What Is Duct Leakage Testing? Duct leakage testing uses a device called a duct blaster to measure how much conditioned air escapes from the duct system before reaching living spaces. The duct blaster pressurizes the duct system to 25 pascals and measures the airflow required to maintain that pressure — revealing how much air is leaking. Why Does Duct Leakage Matter? Leaky ducts can waste 20–30% of a home’s conditioned air. In Massachusetts’s climate, this means heating and cooling systems work significantly harder, driving up energy bills and reducing comfort. For new construction, duct leakage above specified limits fails both HERS requirements and MA Stretch Code compliance. When Is Duct Leakage Testing Required? All HERS Ratings: Duct leakage testing is required for every HERS Rating in Massachusetts, regardless of Stretch Code adoption status. MA Stretch Code compliance: Required in all 300+ municipalities that have adopted the Stretch Code. Mass Save new construction programs: Required to document duct performance for incentive programs. What Are the Duct Leakage Limits? Under the MA Stretch Code and HERS Rating standards, duct systems must meet specific leakage limits measured in CFM25 (cubic feet per minute at 25 pascals). Your HERS Rater will calculate the allowable leakage based on your home’s conditioned floor area and verify compliance through testing. Tips to Pass Duct Leakage Testing Seal all supply and return duct connections with mastic sealant — not just duct tape. Seal around air handler cabinet seams and access panels. Insulate and seal duct boots where they connect to the floor, wall, or ceiling. Have your HVAC contractor pressure-test the duct system before the HERS inspection.

Published: May 2026 | Mass SaveRebatesHERS Rating Massachusetts homeowners and builders have access to some of the most generous energy efficiency incentives in the country through Mass Save. A HERS Rating is the key that unlocks most of them. What Is Mass Save? Mass Save is a statewide energy efficiency program funded by Massachusetts electric and gas utilities including Eversource, National Grid, and others. It provides rebates, incentives, and financing for energy efficiency upgrades to homes and businesses across Massachusetts. Which Mass Save Programs Require a HERS Rating? New Construction Program The Mass Save New Construction Program provides substantial incentives for new homes that achieve specific HERS scores. A certified HERS Rating is required to document and certify compliance. Homes achieving HERS 55 or below (required by Stretch Code) typically qualify for the highest incentive tiers. Zero Energy New Homes (ZENH) The ZENH program provides enhanced incentives for homes targeting HERS 45 or below with renewable energy systems. A HERS Rating is required to verify performance. Home Energy Assessment & Air Sealing For existing homes, Mass Save offers free home energy assessments and rebates for air sealing and insulation work. A blower door test documents air leakage before and after work to qualify for maximum rebates. How Much Can You Save with Mass Save? Incentive amounts vary by program and utility provider, but Mass Save rebates for new construction energy efficiency can reach thousands of dollars per home when combined with federal tax credits available under the Inflation Reduction Act. Pro Tip: HERS Rating Company works directly with Mass Save programs and knows exactly what documentation each program requires. We help ensure your project is documented correctly to maximize your incentives from the start. Federal Tax Credits + Mass Save = Maximum Savings Under the Inflation Reduction Act (IRA), new homes achieving ENERGY STAR certification (which requires a HERS Rating) may qualify for the New Energy Efficient Home Credit (45L), providing $2,500–$5,000 per home in federal tax credits. Combined with Mass Save incentives, the total savings can significantly offset the cost of the HERS Rating and energy efficiency upgrades.

Published: May 2026 | Blower Door TestMassachusettsAir Leakage If you’re building or renovating in Massachusetts, you’ll need a blower door test. But what exactly is it, how does it work, and what does the result mean? Here’s everything you need to know. What Is a Blower Door Test? A blower door test is a diagnostic procedure used to measure a building’s air tightness — specifically, how much air leaks through the building envelope (walls, windows, doors, ceiling, and floor). It gets its name from the large fan (blower door) that is temporarily mounted in an exterior doorway to pressurize or depressurize the building. Key Fact: The MA Stretch Code requires new residential construction to achieve 3.0 ACH50 or less on the blower door test. ACH50 means “air changes per hour at 50 pascals of pressure.” How Does a Blower Door Test Work? Step 1: Setup The technician mounts a calibrated fan in an exterior door frame, sealing the gap around it. All other exterior doors, windows, and intentional openings (fireplace dampers, exhaust fans) are closed. Interior doors are left open. Step 2: Pressurization or Depressurization The fan either blows air into the house (pressurization) or pulls air out (depressurization) to create a 50-pascal pressure difference. The amount of airflow required to maintain that pressure difference tells us exactly how much air is leaking through the building envelope. Step 3: Measurement & Calculation The fan speed and pressure readings are used to calculate CFM50 (cubic feet per minute at 50 pascals) and ACH50 (air changes per hour at 50 pascals). The lower the number, the tighter — and more energy-efficient — the building. What Does the Blower Door Test Measure? ACH50: Air changes per hour at 50 pascals. The MA Stretch Code maximum is 3.0 ACH50 for new residential construction. CFM50: Cubic feet per minute at 50 pascals. Used to compare across different home sizes. Leakage locations: Technicians can use smoke pencils or thermal imaging to identify where air is escaping. Why Is It Required in Massachusetts? The blower door test is required in Massachusetts for several reasons: MA Stretch Code: Any municipality that has adopted the Stretch Code requires a blower door test proving ≤ 3.0 ACH50 for new residential construction. HERS Rating: A blower door test is a required component of all HERS Ratings. Mass Save rebates: Mass Save air sealing rebate programs require a blower door test to document air leakage before and after air sealing work. When Should the Blower Door Test Be Performed? For new construction, the blower door test is typically performed after drywall installation is complete but before final finishes and interior trim. This timing allows any air sealing deficiencies to be corrected before the walls are closed up. What If the Test Fails? If a home fails to achieve 3.0 ACH50 or less, the builder must identify and seal air leakage points and then schedule a re-test. Common failure points include attic bypasses, top plates, plumbing penetrations, electrical boxes, and recessed lighting. Most failures can be corrected with targeted air sealing in a few hours.

Published: May 2026 | MA Stretch CodeBuildersEnergy Code If you’re building new residential construction in Massachusetts, you’ve probably heard about the MA Stretch Code. In this complete guide, we explain exactly what it requires, which municipalities have adopted it, and what you need to do to comply. What Is the MA Stretch Code? The Massachusetts Stretch Energy Code is an optional — but widely adopted — addition to the base Massachusetts energy code (IECC 2021). It sets more stringent energy efficiency requirements for new residential and commercial construction than the base code. The Stretch Code is administered by the Massachusetts Department of Energy Resources (DOER) and is required in any municipality that has adopted it. As of 2026, over 300 Massachusetts cities and towns require Stretch Code compliance for new construction. MA Stretch Code Requirements at a Glance 55 HERS Score or Below Maximum HERS Index score for new residential construction 3.0 ACH50 or Less Maximum air leakage rate measured by blower door test 4% Duct Leakage Max Total duct leakage to outside as % of total airflow The Three Core Tests Required 1. HERS Rating (HERS Index Score ≤ 55) A RESNET-certified HERS Rater must evaluate the home using energy modeling software and assign a HERS Index score. The score must be 55 or below. The average new home built to code scores around 100; a HERS 55 home uses roughly 45% less energy than average. 2. Blower Door Test (≤ 3.0 ACH50) A blower door test measures how airtight the home’s building envelope is. Under the MA Stretch Code, new residential construction must achieve 3.0 ACH50 or less. The test is typically performed after drywall is installed but before final finishes. 3. Duct Leakage Test Using a duct blaster device, the rater measures how much conditioned air escapes through duct leaks. Leaky ducts can waste 20–30% of heating and cooling energy. The Stretch Code requires duct systems to meet specific leakage limits. Does My City Require the Stretch Code? Over 300 Massachusetts municipalities have adopted the Stretch Code, including Boston, Cambridge, Newton, Framingham, Worcester, Springfield, Lowell, Quincy, and most other cities and larger towns. Check with your local building department to confirm requirements for your specific project. When Must You Comply? Stretch Code compliance is required for: New residential construction (single-family, multifamily, ADUs) Major renovations that trigger energy code review Projects seeking building permits in Stretch Code municipalities How Does the Process Work? Working with a RESNET-certified HERS Rater for full Stretch Code compliance typically follows this process: Plans Review: Before construction, your rater reviews plans and creates an energy model to verify the design will meet HERS 55. Construction Inspection: During construction, the rater verifies insulation, windows, and HVAC match the model. Blower Door Test: After drywall, the rater performs the blower door test.
