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 Brockton
From permit-ready planning to your final certificate, here is exactly how we guide Brockton 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.
Brockton and the Massachusetts Specialized Stretch Code
As part of Climate Zone 5A, Brockton follows the Massachusetts Specialized Stretch Code, which asks new homes to do more than hit an insulation target — they must be laid out today for the solar panels and EV chargers owners are likely to add tomorrow.
Solar-Ready Requirements
Under provision RB102, a Brockton build has to keep a clear stretch of roof and reserve panel space in the electrical service, turning a later solar install into a straightforward add-on instead of a retrofit.
EV-Ready Requirements
Provision RB103 requires the conduit and panel capacity for a vehicle charger to be roughed in during construction, so a Brockton household can energize a charger later without opening walls.
Talk directly with the owner
Wondering how these rules shake out for your specific Brockton build? Reach Dominic Zammuto directly — he owns the company and is a registered Mass Save partner — for a straight answer on your score and rebate options before the shovels go in.
What a HERS Index Score Really Tells Brockton Owners
Think of the HERS Index as a miles-per-gallon rating for a house. It compresses a Brockton home’s projected energy use into one figure you can compare against any other home, where lower is always better.
The 100 mark
A home built precisely to the 2006 model code earns a 100. Plenty of the older housing stock in Brockton scores higher, a sign it wastes more energy than that benchmark.
Down to zero
Reaching 0 means the house generates as much energy as it consumes across the year. Every step a Brockton home takes toward zero trims its reliance on purchased power.
The value of a point
Roughly one percent of annual energy use hides behind each Index point, so even a modest drop in a Brockton score translates into real savings month after month.
The Testing Behind Every Brockton Rating
Numbers on paper only matter if the house backs them up. For each Brockton project we pair up-front modeling with physical diagnostics so the final score mirrors real-world performance.
- Energy modeling: we build a digital twin of the Brockton home early on, testing envelope, systems and fuel choices so problems surface on screen rather than on site.
- Blower-door testing: by pulling the house to negative pressure we quantify air leakage through the shell, the factor that most affects comfort and heating bills across Brockton.
- Duct-leakage testing: we pressurize the ductwork to catch conditioned air slipping into unconditioned spaces and confirm the system passes before certification.
Why HERS and the Stretch Code Go Hand in Hand in Brockton
In Massachusetts a HERS rating is baked directly into the energy code as a compliance route, which is exactly why so many Brockton permits come down to the number we deliver.
- An IECC 2021 base: the state Stretch Code stacks added efficiency on top of the 2021 international code, and a qualifying HERS score is one recognized way to prove compliance.
- Fuel type shifts the bar: a fully electric Brockton home answers to a different score than one burning gas or oil, so that choice reshapes the target from the outset.
- Rebates on the far side: the verified rating that clears the code is also your ticket to Mass Save incentives — the latest terms live on Mass.gov.

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

HERS Score Requirements in Brockton 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 |
In Brockton the trend line only points one way — downward. New homes cleared the 2022 code at HERS 55, had to reach 52 once 2023 began, and since July 2024 must hit 42 with any fossil fuel on board or 45 when fully electric. Since the applicable target is locked to your permit date, a Brockton plan drafted to a looser earlier number can fall short today, which is why we grade each home against the precise code its permit activates.
