New Bedford is a city in Bristol County, Massachusetts, United States. It is located on the Acushnet River in what is known as the South Coast region, abutting Buzzards Bay. New Bedford is located in Bristol County, Massachusetts. The 02740 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 New Bedford?
New construction, additions, and major renovations in New Bedford, Bristol County are reviewed against the Massachusetts energy code, and a HERS rating is the standard way to document compliance.
What climate zone is New Bedford in?
Like all of Massachusetts, New Bedford is in IECC climate zone 5A, which sets the insulation, air-sealing, and mechanical-system targets a HERS rater verifies.
Do existing homes in New Bedford need a HERS rating?
Most existing homes only need a rating for major renovations, additions, or energy-code permits; new construction in New Bedford almost always requires one.
How does a HERS rating help New Bedford homeowners?

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 New Bedford may need a HERS rating depending on project size, code path, and permit requirements.
Why local experience matters
Local experience helps ensure your project is reviewed with Massachusetts requirements, practical construction details, and real jobsite conditions in mind.
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 New Bedford
From permit-ready planning to your final certificate, here is exactly how we guide New Bedford 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.
New Bedford and the Massachusetts Specialized Stretch Code
New Bedford sits in Climate Zone 5A, and under the Massachusetts Specialized Stretch Code new residential construction has to be built ready for a lower-carbon future — not just insulated well, but pre-wired and pre-planned for solar and EV charging.
Solar-Ready Requirements
New homes must set aside unshaded roof space and spare electrical capacity for a future photovoltaic array (provision RB102), so adding panels later in New Bedford is a plug-in job rather than a rebuild.
EV-Ready Requirements
Rough-in for electric-vehicle charging (provision RB103) has to be in place, giving New Bedford owners a ready circuit for a home charger without tearing open finished walls.
Talk directly with the owner
Have a question about how the Stretch Code or your rebates apply to a New Bedford project? You can speak directly with Dominic Zammuto, the owner and a registered Mass Save partner, rather than being passed to a call center. We’ll walk you through the numbers before you commit to anything.
Making Sense of the HERS Index for New Bedford Homeowners
The HERS Index is the yardstick every New Bedford rating comes back to. It turns a home’s modeled energy use into a single comparable number, so a lower score always means a tighter, cheaper-to-run house.
100 is the baseline
A brand-new home built exactly to the 2006 reference standard scores a 100. Most older New Bedford houses actually land above that, meaning they burn more energy than the baseline.
Zero is net-zero
A score of 0 means the home produces as much energy as it uses over a year. The closer a New Bedford project gets to zero, the less it leans on the grid.
Every point counts
Each point on the Index reflects roughly one percent of energy use, so shaving even a few points off a New Bedford home’s score shows up on the utility bill.
How We Verify Energy Performance in New Bedford
A HERS score is only as trustworthy as the testing behind it. On every New Bedford project we combine modeling with hands-on diagnostics so the rating reflects how the house really performs.
- Energy modeling: before construction we simulate the New Bedford home’s envelope, mechanicals and fuel choices to predict its score and flag weak points early.
- Blower-door testing: we depressurize the house to measure exactly how much air leaks through the shell — the single biggest driver of comfort and heating costs on the New Bedford coast.
- Duct-leakage testing: we pressurize the duct system to find conditioned air escaping into attics or crawlspaces, then verify it meets code before sign-off.
How HERS Ties Into the Stretch Code in New Bedford
In Massachusetts the HERS rating isn’t a standalone number — it is one of the compliance paths written into the state energy code, which is why New Bedford permits so often hinge on it.
- Built on IECC 2021: the Massachusetts Stretch Code layers extra efficiency onto the 2021 international base code, and a passing HERS score is an accepted way to demonstrate you meet it.
- Fuel choice moves the target: all-electric New Bedford homes are held to a slightly different score than fossil-fuel homes, so the design decision changes the math from day one.
- A doorway to rebates: the same verified rating that satisfies the code also unlocks Mass Save incentives — you can review the current rules on Mass.gov before you build.

FAQ About HERS Rating New Bedford MA
Common questions about HERS ratings in New Bedford, 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 New Bedford cost?
A HERS rating in New Bedford 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 New Bedford?
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 New Bedford?
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 New Bedford?
If New Bedford 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 New Bedford?
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 New Bedford?
Yes. Working with a certified HERS rater can unlock Mass Save incentives for new construction and renovations.

HERS Score Requirements in New Bedford 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 |
The pattern in New Bedford is a steady tightening: new-construction targets stepped from HERS 55 under the 2022 code down to 52 in 2023, and since July 2024 mixed-fuel homes must reach 42 while all-electric builds are allowed 45. Because the code applied is the one in force on your permit date, a New Bedford design drawn to an older figure can quietly miss today’s mark — so we model every home against the exact standard its permit triggers.
