Helpful answers for homeowners, builders, and developers planning a project in Framingham.
Framingham is a city in the Commonwealth of Massachusetts, United States. Incorporated in 1700, it is located in Middlesex County and the MetroWest subregion of the Greater Boston metropolitan area. Framingham is located in Middlesex County, Massachusetts. The 01701 area, like the rest of Massachusetts, sits in IECC climate zone 5A, which shapes insulation, air-sealing, and HVAC requirements for HERS rating and energy code compliance.
Where does HERS rating apply in Framingham?
New construction, additions, and major renovations in Framingham, Middlesex County are reviewed against the Massachusetts energy code, and a HERS rating is the standard way to document compliance.
What climate zone is Framingham in?
Like all of Massachusetts, Framingham is in IECC climate zone 5A, which sets the insulation, air-sealing, and mechanical-system targets a HERS rater verifies.
Do existing homes in Framingham need a HERS rating?
Most existing homes only need a rating for major renovations, additions, or energy-code permits; new construction in Framingham almost always requires one.
How does a HERS rating help Framingham homeowners?
A lower HERS Index signals a more energy-efficient home, lower utility bills, and easier code compliance for projects in Framingham.
What is a HERS Rating?
A HERS Rating measures the energy efficiency of a home and is commonly used for new construction, additions, and major renovations in Massachusetts.
Who may need one?
Builders, homeowners, and developers in Framingham may need a HERS rating depending on project size, code path, and permit requirements.
Why local experience matters

What the process may include
Depending on the project, the process may include plan review, energy modeling, field verification, and final testing support.
Our 5-Step HERS Rating Process in Framingham
From permit-ready planning to your final certificate, here is exactly how we guide Framingham projects through HERS compliance — including the consulting step most raters leave out.
Plan Review & Preliminary Report
We start by reviewing your plans and issuing the preliminary HERS report your building department needs before a permit can be pulled.
Equipment Consulting
Before anything is installed, we confirm your appliances, HVAC and equipment are the right choices. Many companies skip this and just hand over a report — this step keeps you from buying the wrong gear.
Mid-Point Inspection
Once framing is done, we verify insulation and air sealing are installed correctly and to code, capturing what the HERS report depends on before drywall goes up.
Final Testing
We complete blower-door testing, duct-leakage testing and ERV balancing. Proper ERV balancing is critical, since an unbalanced system can create pressure problems throughout the home.
Final Certificate
Finally, we issue the signed HERS certificate to close out your building permit and set you up to apply for the Mass Save rebates you’ve earned.
Talk directly with the owner
Your Framingham rating is handled by Dominic Zammuto, owner of Home Energy Efficiency Consultants and a Mass Save partner. From the opening plan review to the final blower-door number, you deal directly with the person who signs your report — never a call center.
What a Framingham HERS Index Number Tells You
Home energy efficiency nationwide is boiled down to one figure, the HERS Index, and the twist is that a lower score is the better score.
The yardstick
The reference home — a standard new build — sits at 100. Every Framingham home is compared to that yardstick, which keeps scores meaningful from one property to the next.
Net-zero mark
A score of 0 means annual energy production equals annual use. The closer a Framingham home lands to 0, the closer it comes to running net-zero.
A point per percent
Each Index point is about one percent of modeled energy use, so a Framingham home scoring 60 is roughly 40 percent more efficient than the reference home — a gap you notice on every bill.
Inside the Framingham HERS Testing Process
A HERS rating is built on measurements taken at the home, not assumptions. Three diagnostics do the heavy lifting on any Framingham project.
- Energy modeling. Before ground is broken, we build a full model of the Framingham home — insulation, glazing, mechanical systems and air sealing — to project the score and reveal the best opportunities to improve it.
- Blower-door testing. A calibrated fan draws the house to a set pressure so leakage through the building shell can be measured exactly. A tighter Framingham envelope trims heating costs and lowers the score.
- Duct-leakage testing. Where ductwork carries heating and cooling, we pressurize it to find conditioned air slipping into unconditioned space — a frequent, costly loss that pushes a Framingham HERS score higher.
HERS Ratings and the Massachusetts Stretch Code in Framingham
Massachusetts holds new construction to one of the country's most rigorous energy codes, and a HERS rating is an accepted way to prove a Framingham home complies.
Built on IECC 2021
The Stretch Code takes the 2021 International Energy Conservation Code and layers on Massachusetts amendments under 225 CMR 22. A certified RESNET HERS rating is one recognized path for a Framingham project to satisfy it.
Your fuel choice shifts the target
All-electric and fossil-fuel homes face different requirements, and all-electric designs earn HERS-point credits. We help Framingham owners see how heating and hot-water decisions affect both the score and the code target.
Connected to Mass Save
A strong HERS score can also make a project eligible for rebates through Mass Save, the statewide efficiency program. As a Mass Save partner, we help Framingham homeowners match the rating to the incentives on offer.
Confirm the current code
Because the code is periodically updated, the Commonwealth's Stretch Energy Code page is the authoritative source. We keep every Framingham rating aligned to the edition currently in force.

FAQ About HERS Rating Framingham MA
Common questions about HERS ratings in Framingham, Massachusetts.
What is a HERS rating?
A HERS (Home Energy Rating System) rating is the national industry standard for measuring a home's energy efficiency. A certified HERS Rater reviews the plans and performs on-site inspections and testing, including a blower door test, to produce a score. Lower is better: a standard new home built to 2006 code scores 100, while a net-zero home scores 0.
What is a good HERS score?
Any score below 100 beats a standard new home, and the lower the number the more efficient the home. A score of 50 means the home is about 50% more efficient than a standard new build, while older unimproved homes often score 130 or higher. Massachusetts code targets are now well below 100.
How have Massachusetts HERS requirements changed in recent years?
Massachusetts has steadily tightened the maximum allowable HERS score. The required score for new homes was around 55 in 2022, dropped to 52 in 2023, and tightened to HERS 42 for mixed-fuel homes and 45 for all-electric homes as of July 1, 2024. The 2023 update also adopted the 2021 IECC as the base code and removed the earlier 5-point HERS credit for rooftop solar, pushing toward efficiency and electrification.
How much does a HERS rating in Framingham cost?
A HERS rating in Framingham typically costs:
- Single-family homes: $1,850–$2,500
- Accessory dwelling units (ADUs): $1,600–$1,850
- Multifamily: $900–$1,450 per unit
Final pricing depends on home size, complexity, and the number of required site visits.
What HERS score do I need to pass in Framingham?
As of July 1, 2024, new construction needs a HERS 42 for homes using any fossil fuel and a HERS 45 for all-electric homes, verified by a certified RESNET HERS rater. Low-emission concrete comes in around 45 with gas or 48 all-electric, an ADU is 55 all-electric or 52 with gas, and multifamily matches the single-family requirement.
What triggers a HERS rating in Framingham?
New construction almost always requires one. Under energy code Section R502, an addition triggers a HERS rating when the added conditioned floor area exceeds 1,000 square feet or doubles the size of your existing conditioned space (more than 100% of the existing conditioned floor area), requiring the combined dwelling to meet the maximum HERS ratings in Table R406.5.
Do renovations or alterations require a HERS rating?
They can. Under Section R503, extensive alterations (or IEBC Level 3 alterations) that exceed 1,000 square feet or double the size of the existing conditioned space (over 100% of the existing conditioned floor area) must meet the maximum HERS ratings in Table R406.5. Smaller alterations must still meet component requirements for insulation, replacement windows, water heating, and lighting.
Do I need a HERS rating in Framingham?
If Framingham has adopted the Massachusetts Stretch Energy Code, then yes for new homes, larger additions, and extensive renovations. A certified HERS rater can confirm whether your specific project triggers the requirement.
What kind of windows do I need to meet the new energy code?
All-electric homes favor a U-value of .25/.26 with an SHGC of .42 or higher, while gas homes favor tighter values. For replacements specifically, Section R503.1.1.1 requires new units, including sash and glazing, to meet the U-factor and SHGC in Table R402.1.3.
What kind of insulation do I need to pass a HERS rating?
You generally need around R-21 to R-30 depending on whether you go gas or all-electric.
What if I do not want to use spray foam?
You can use exterior insulation and then use mineral wool inside the wall.
How can I build to energy code in a cost-effective way?
Using low-emission concrete can reduce the HERS score by about 3 points, saving close to $20k or more between systems and upgrades.
What is an ERV system and do I need it in Framingham?
Yes, it is now required by code. You can use an ERV or HRV to satisfy the requirement for balanced mechanical ventilation.
How much CFM do I need for my ERV?
It is based on bedrooms, square footage, and insulation volume, along with the ACH from your blower door test.
What do I need to start a HERS rating?
You need a set of architectural plans and to know whether you will go gas or all-electric.
How can I improve my score and what affects my score?
Your score is affected by windows, insulation, HVAC, and appliances such as the washer, dryer, dishwasher, and fridge.
Does a HERS rating add value to my home?
Yes. Energy-efficient HERS-rated homes have been shown to sell at a premium over comparable standard homes, on top of ongoing savings from lower utility bills.
Are there rebates for a HERS rating in Framingham?
Yes. Working with a certified HERS rater can unlock Mass Save incentives for new construction and renovations.

HERS Score Requirements in Framingham by Year
Massachusetts Stretch Energy Code HERS thresholds have tightened over time. These are the maximum HERS Index scores required to pass for new construction, based on when the building permit was filed.
| Time Frame | Required HERS Score |
|---|---|
| 2022 | New homes: HERS 55 or lower |
| Effective Jan 1, 2023 | New homes: HERS 52 or lower |
| Effective July 1, 2024 (current) | HERS 42 for homes using any fossil fuel; HERS 45 for all-electric homes |
| Major remodels, additions & change-of-use | Generally HERS 65 to 75 |
| ADUs (per recent updates) | Around HERS 52 mixed-fuel / 55 all-electric |
Looking at the years together, you can see how much further a Framingham home has to go today than it did just a couple of code cycles ago. The 2022 standard was satisfied at HERS 55, the 2023 cycle brought it to 52, and the July 2024 update sharpened it to 42 for fossil-fuel homes and 45 for all-electric builds. Since your rating is measured against whichever code is live on your permit date, a Framingham design based on an older, gentler target can slip out of compliance — we head that off by modeling your home to the exact standard your permit sets.

Mass Save Rebates & Incentives
Here you can review the Mass Save incentives available to Framingham projects. Brand-new homes and major renovations move through separate tracks, and your rebate grows the further your HERS score beats the code target — a more efficient Framingham home means a bigger payout. We take on the modeling and the paperwork so your project claims every incentive it qualifies for.
A HERS rating can unlock Mass Save incentives for eligible projects in Framingham. Incentives are available for both new construction and for renovations and additions. Actual amounts depend on project type, number of units, efficiency level, and program eligibility.
For a Framingham project, the dollar figure depends on the efficiency path pursued and the number of units built. On the all-electric Base path, a new single-family home begins near $7,500 and rises toward roughly $11,250 for a four-unit building. Achieving the ENERGY STAR path — 30 percent or more energy savings, or a HERS Index of 45 — lifts that range to about $15,000 to $22,500, and a Passive House build can extend to between $25,000 and $40,000 depending on unit count. When it comes to renovations, Mass Save Pay-for-Savings incentives reach up to $10,000 on the base tier or $15,000 for all-electric homes, while larger Level 1 and Level 2 retrofits run from $20,000 to $60,000 according to scope and units. Because each incentive is contingent on verified energy modeling and field testing, we deliver the HERS documentation a Framingham project needs to earn the highest rebate available to it.
New Construction Incentives (Single-family, 1-4 units)
| Path | Single Family | 2-Unit | 3-Unit | 4-Unit |
|---|---|---|---|---|
| Base (all-electric) | $7,500 | $8,750 | $10,000 | $11,250 |
| ENERGY STAR (30%+ savings or HERS 45) | $15,000 | $17,500 | $20,000 | $22,500 |
| Passive House | $25,000 | $30,000 | $35,000 | $40,000 |
Incentives up to $25,000 are available for the construction of single-family homes.
Renovations & Additions Incentives (Single-family, 1-4 units)
| Tier | Incentive |
|---|---|
| Base | Pay-for-Savings ($0.30/kWh + $30/MMBtu + savings x $2,500); up to $10,000 total |
| All-Electric Base | Pay-for-Savings ($0.40/kWh + savings x $3,000); up to $15,000 total |
| Level 1 | Single-family $20,000; 2-unit $30,000; 3-unit $40,000; 4-unit $50,000 |
| Level 2 | Single-family $30,000; 2-unit $40,000; 3-unit $50,000; 4-unit $60,000 |
Eligibility: projects within Sponsor electric service territory. Renovations must be extensive (about 50% or more of the original home) or additions of at least 500 square feet. Full terms and conditions are available on the Mass Save website. Incentive programs can change.
