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

HERS Score Requirements in Billerica
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.
| Project type | Mixed-fuel (gas) target | All-electric target |
|---|---|---|
| New construction | HERS 42 | HERS 45 |
| New construction with embodied carbon credit (carbon trade-off) | HERS 45 | HERS 48 |
| Accessory dwelling units (ADUs) | HERS 52 | HERS 55 |
| Major remodels, additions & change-of-use | HERS 65 | HERS 70 |
Historical thresholds: new homes required HERS 55 in 2022, HERS 52 as of January 1, 2023, and HERS 42 (mixed-fuel) / 45 (all-electric) as of July 1, 2024. Projects using the embodied carbon trade-off may build to HERS 45 with gas or HERS 48 all-electric.
When is a HERS rating required in Billerica?
Under the Massachusetts Stretch Code, a certified HERS rating is required in Billerica for the following residential projects:
- New construction: all new residential dwellings.
- Large additions: any addition exceeding 1,000 sq ft or increasing the conditioned floor area by more than 100%.
- Extensive alterations: renovations affecting more than 1,000 sq ft or more than 100% of the existing conditioned floor area, which trigger a whole-home rating of the entire dwelling unit.
The main exception is when a project only converts existing unconditioned basement or attic space into conditioned space by shifting the home's thermal boundary — this typically does not require a rating. When a whole-home rating is triggered, both the new and existing portions must meet the HERS target together, so we help balance the design to reach the score without unnecessary upgrades to the original structure.
Solar-ready and EV-ready requirements under the Specialized Stretch Code
Beyond the HERS score, Billerica's Specialized Stretch Code adds readiness requirements that we account for during plan review:
- Solar-ready zone (Sections RB102–RB103): new residential construction — including detached one- and two-family homes and townhouses with at least 600 sq ft of suitably oriented roof area — must reserve a solar-ready zone for the future installation of a solar photovoltaic or solar thermal system. Additions under 1,000 sq ft are exempt.
- EV-ready charging: the Specialized Stretch Code requires new residential parking to be electric-vehicle ready, with the electrical capacity, conduit, and panel space needed to add EV charging later without major rewiring. We confirm your electrical design leaves room for these provisions early, so they don't become a costly retrofit.
Planning for solar-ready and EV-ready provisions before permitting keeps your Billerica project fully compliant and avoids expensive changes once framing and electrical rough-in are underway.
Note: HERS requirements are set by the Massachusetts Stretch and Specialized Energy Codes and can change with code updates. Figures reflect the current code at the time of writing.
Mass Save Rebates & Incentives
A HERS rating can unlock Mass Save incentives for eligible projects in Billerica. 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.
In practice, Billerica new-construction incentives scale with efficiency and unit count. All-electric homes on the Base path earn roughly $7,500 for a single-family home, rising to about $11,250 for a 4-unit building. Hitting the ENERGY STAR path (30%+ savings or HERS 45) increases that to about $15,000–$22,500, and a Passive House project can qualify for roughly $25,000–$40,000 depending on unit count. For renovations and whole-home retrofits, Mass Save offers Pay-for-Savings incentives up to $10,000 (base) or $15,000 (all-electric), while larger Level 1 and Level 2 projects can reach $20,000–$60,000 based on scope and number of units. Because eligibility depends on verified modeling and field-tested performance, we document the HERS results needed to help your project capture the maximum available incentives.
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 |
