Common Questions About the East Brookfield Energy Code
Is a HERS rating required in East Brookfield, MA?
Not by local code — East Brookfield is one of just 49 Massachusetts municipalities still on the Base Energy Code (10th Edition, IECC 2021 with MA amendments), so the Stretch Code HERS mandate does not apply. A HERS rating is still an accepted compliance path and is required for Mass Save® new-construction incentives.
undefined
There is no mandatory HERS maximum under the Base Code in East Brookfield, but the ERI compliance path follows IECC 2021 limits, and Mass Save incentive tiers require HERS 45 or better for the ENERGY STAR® tier.
undefined
East Brookfield follows the Massachusetts Base Energy Code (10th Edition, IECC 2021 with amendments) as of the June 2026 Mass.gov adoption list — one of only 49 communities statewide that have not adopted the Stretch Code.
Official Maximum HERS Index Scores (Table R406.5)
For comparison, here is the official maximum-HERS table that applies in Massachusetts Stretch Code and Specialized Code communities (Table R406.5, 2025 DOER Technical Guidance):
| Building type | New construction (permits after 7/1/2024) | New construction w/ embodied-carbon credit (R406.5.2) | Accessory Dwelling Units | Major alterations, additions, change of use |
|---|---|---|---|---|
| Mixed-fuel building | 42 | 45 | 52 | 65 |
| Mixed-fuel + solar electric | 42 | 45 | 55 | 70 |
| All-electric building | 45 | 48 | 55 | 70 |
| All-electric + solar electric | 45 | 48 | 58 | 75 |
Scores are measured before counting on-site renewable generation (per R406.5). Historic buildings may opt out for alterations under R503.1.1. Embodied-carbon credits (+3 points) come from low-GWP concrete and insulation EPDs per Table R406.5.3/R406.5.4.
What Base Code Status Means for East Brookfield Projects
As one of only 49 Base Code communities, East Brookfield projects follow the 10th Edition code (IECC 2021 with MA amendments) via the prescriptive path, the simulated-performance path, or the Energy Rating Index (HERS) path — without the Stretch Code’s lowered HERS caps shown above. Builders in East Brookfield still order HERS ratings for the ERI compliance path, for Mass Save® incentives (which always require HERS verification), and to document energy performance for buyers. If East Brookfield adopts the Stretch Code at a future town meeting, the table above becomes mandatory — surrounding towns already enforce it, so East Brookfield builders often test to those standards today.
