- REScheck documents the prescriptive residential path for Ashland additions, alterations and renovations (from $300); new-construction performance projects use a full HERS energy model instead.
- Commercial projects use COMcheck for the prescriptive path (from $600); larger new commercial buildings need third-party performance certification under the Stretch Code.

REScheck & COMcheck Ashland MA
Fast, accurate REScheck and COMcheck energy code compliance reports for residential and commercial projects in Ashland, Massachusetts. We prepare the documentation your building department needs to issue a permit — without the cost of a full performance-path energy rating when your project does not require one.
What we deliver
A stamped, signed compliance report matched to your plans and ready to upload with your Ashland building permit application.
REScheck vs. COMcheck: What’s the Difference?
Both are free compliance software tools developed by the U.S. Department of Energy (DOE) to demonstrate that a building meets the International Energy Conservation Code (IECC). They document your envelope, and for commercial work your lighting and mechanical systems, so a plan reviewer in Ashland can confirm compliance quickly.
What is a REScheck?
REScheck is DOE software for residential compliance — detached one- and two-family homes and multifamily buildings three stories or fewer. It runs a UA (insulation and window) trade-off calculation against the IECC, letting extra performance in one assembly offset another so the whole envelope still passes.
What is a COMcheck?
For commercial and four-plus-story residential buildings, COMcheck is required. It documents envelope, lighting, and mechanical compliance against the IECC or ASHRAE Standard 90.1 and produces the certificates a commercial plan reviewer expects.
When Do You Need a REScheck in Ashland?
REScheck is the simplest path for smaller residential projects in Ashland that do not trigger a full performance-path energy rating. It is typically the right tool when your project is:
- New residential construction or an addition under 1,200 square feet that does not require a HERS rating
- Window and insulation upgrades that must be documented for a building permit
- Permit applications needing residential envelope documentation on the prescriptive or UA trade-off path
- Detached accessory structures with conditioned space
- Multifamily buildings of three stories or fewer
When Do You Need a COMcheck in Ashland?
COMcheck is required for commercial and larger projects in Ashland. Reach for a COMcheck when your project involves:
- New mechanical (HVAC) or service water heating systems in commercial spaces
- Envelope work on commercial structures requiring IECC or ASHRAE 90.1 compliance
- Restaurant build-outs and retail white-box improvements
- Medical, dental, and professional office construction
- Warehouse, industrial, and light-manufacturing conditioned spaces

Ashland Specialized Energy Code — HERS Index Targets
Ashland enforces the Massachusetts Specialized (Opt-In) Energy Code. The required HERS score depends on fuel type and project scope — a lower index is stricter.
| Project type | Mixed-fuel | Mixed-fuel + solar | All-electric | All-electric + solar |
|---|---|---|---|---|
| New construction | HERS 42 | 42 | 45 | 45 |
| New construction — embodied-carbon credit | 45 | 45 | 48 | 48 |
| Accessory dwelling unit (ADU) | 52 | 55 | 55 | 58 |
| Major alteration / renovation / change of use | 65 | 70 | 70 | 75 |
A HERS rating is triggered by new construction, additions over 1,000 sq ft (or more than 100% of the existing conditioned area), and Level 3 alterations over 1,000 sq ft affecting more than 50% of the home. New homes must also pass a blower-door test at 3.0 ACH50 and include electrification-ready wiring for heat pumps, EV charging, and solar. We model your Ashland project up front so you know the exact target and the fastest path to hit it — call (617) 501-6788.
