North Brookfield code requirements at a glance
- A HERS rating is required in North Brookfield for: new construction; additions over 1,000 sq ft (or greater than 100% of the existing conditioned floor area); and extensive Level 3 alterations over 1,000 sq ft affecting more than 50% of the conditioned floor area.
- New home, mixed-fuel (gas heat, hot water or cooking): must reach HERS 42 or lower.
- New home, all-electric: must reach HERS 45 or lower.
- Embodied-carbon materials credit: allows up to HERS 48.
- ADU, mixed-fuel (gas): HERS 52; ADU, all-electric: HERS 55; ADU with the embodied-carbon credit: HERS 58.
- Major additions and renovations: HERS 65 (mixed-fuel) or HERS 70 (all-electric).
- Air tightness: a blower door test at 3.0 ACH50 or tighter; duct leakage capped at 4.0 CFM25 per 100 sq ft total leakage (8.0 when all ducts are inside conditioned space - the test is still required).
- Also required in new homes: whole-house mechanical ventilation (ASHRAE 62.2) and EV-ready wiring; compliance runs through the HERS / Energy Rating Index path (2025 code section R406).
How compliance is verified
- Energy model from your plans, a pre-drywall (rough) inspection, blower door and duct leakage testing, then a final HERS certificate filed with the North Brookfield building department.
- Same-day preliminary HERS reports; blower door and duct results in 24-48 hours, with fail-fix guidance if a home misses the target.

Energy Code Path for North Brookfield Projects
North Brookfield's Building Inspector works out of 215 North Main St and shares office hours with a neighboring town, and residents may go to either office for a permit. Applications dropped off must include the fee and a self-addressed stamped envelope.
The state's adoption list shows North Brookfield on the base energy code, with no Stretch Code or Specialized (Opt-In) Code adoption. That changes which compliance path a project can take:
- New homes: the prescriptive path, REScheck or a performance/HERS approach; the Stretch Code HERS 42/45 caps do not apply
- Additions and renovations: REScheck or the prescriptive tables, with no HERS 65/70 target unless the town adopts the Stretch Code
- Commercial: COMcheck for buildings up to 20,000 sq ft
The town posts a building permit form online, so the energy compliance report can be printed and attached before the application goes in.
REScheck works well for a straightforward addition, but a design with a lot of glass or an unusual wall assembly can pass more easily on a performance model, so it is worth comparing both before the plans are stamped.
The energy paperwork is reviewed when the permit is issued and again before the certificate of occupancy, so the final report should match the approved plans.
Heat pump sizing, duct location and the ventilation plan are easiest to settle before framing, and those choices move the HERS score more than most finishes do.
A design change during construction, such as different windows or a new heating system, can change the score, so it is worth rerunning the model before the change is made.
A HERS rating scores the finished home against a reference house built to the 2006 energy code, which is set at 100, so a lower number means a more efficient home.
The closest HEEC office to North Brookfield is Marlborough, at 272 Lincoln St C1. We can review plans, run the model and schedule the pre-drywall and final tests around your inspection dates.
