REScheck & COMcheck Barre MA
Need a REScheck or COMcheck in Barre? We produce permit-ready energy code compliance reports for homes and commercial buildings across Worcester County, matched precisely to your plans so your project clears plan review the first time.
What we deliver
A signed compliance report matched to your plans and ready to upload with your Barre building permit application.
What Is a REScheck and What Is a COMcheck?
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 Barre can confirm compliance quickly.
What is a COMcheck?
COMcheck handles commercial work and high-rise residential of four stories or more. The DOE tool evaluates envelope, lighting (interior and exterior), and mechanical systems against either the IECC or ASHRAE 90.1, with trade-offs allowed across components.
What is a REScheck?
For homes, REScheck is the go-to. This DOE program checks residential envelopes — detached houses and multifamily up to three stories — and allows insulation and fenestration trade-offs to show prescriptive or component-based IECC compliance.
When Do You Need a REScheck in Barre?
REScheck is the simplest path for smaller residential projects in Barre that do not need a HERS rating. It is typically the right tool for:
- Residential additions of 1,000 sq ft or less that are not more than 100% of the existing home
- Basement and attic conversions that do not change the footprint or roofline
- Renovations and alterations to existing homes that need envelope documentation
- Detached accessory structures with conditioned space, where Barre's building department accepts REScheck
- New homes only in base-code towns; Stretch and Specialized Code towns require a HERS rating or Passive House for new homes
COMcheck Projects in Barre
COMcheck is required for commercial and larger projects in Barre. Reach for a COMcheck when your project involves:
- Medical, dental, and professional office construction
- Envelope work on commercial structures requiring IECC or ASHRAE 90.1 compliance
- New mechanical (HVAC) or service water heating systems in commercial spaces
- Warehouse, industrial, and light-manufacturing conditioned spaces
- Restaurant build-outs and retail white-box improvements

Which Energy Code Report Does a Barre Project Need?
Barre adopted the Massachusetts Stretch Code effective January 1, 2012 and is not one of the 60 communities on the Specialized (Opt-In) Code, so projects follow the Massachusetts Stretch Code (225 CMR 22.00 and 23.00). We confirm Barre's current code status against the state list before we prepare any report.
| Your Barre project | What the energy code paperwork usually is |
|---|---|
| New single-family home or low-rise residential building | In Stretch Code towns, a HERS rating (maximum HERS 42 mixed-fuel, 45 all-electric) or Passive House. REScheck is not accepted for new homes under the Stretch Code. |
| Residential addition of 1,000 sq ft or less (and not over 100% of the existing home) | REScheck (REScheck-Web, 2023 Massachusetts Stretch Code) or the prescriptive tables |
| Residential addition over 1,000 sq ft or over 100% of the existing home | A HERS rating of the whole house (HERS 65 or lower mixed-fuel, 70 or lower all-electric) |
| Basement or attic conversion with no change to footprint or roofline | No HERS rating required; REScheck or prescriptive documentation |
| Residential renovation or alteration | Prescriptive alteration rules; REScheck can document the envelope. Large "extensive" alterations over 1,000 sq ft may need a HERS rating. |
| New commercial building up to 20,000 sq ft | COMcheck: Envelope, Lighting and Mechanical certificates plus the Plan Review Inspection Checklist |
| New commercial building over 20,000 sq ft | COMcheck Lighting and Mechanical, with the envelope shown by backstop and thermal-bridge calculations, on a performance path (Targeted Performance/TEDI or ASHRAE 90.1 Appendix G) or Passive House |
| Commercial addition, alteration, or lighting/HVAC change | COMcheck for the altered systems |
| Multifamily building over 12,000 sq ft | Passive House or a HERS/performance path |
Based on 225 CMR 22.00 and 23.00 (Massachusetts energy code, 2025 edition). Building departments make the final call, so we confirm the path for your project before we start. Barre is in Worcester County, served from our Marlborough (272 Lincoln St) office.
How We Prepare Your Barre REScheck or COMcheck
Send your plans
Email the permit set for your Barre project. We tell you the same day whether you need a REScheck, a COMcheck or a HERS rating.
We model the building
We enter every assembly, window, light fixture and HVAC unit as designed and flag anything that fails before the plan reviewer sees it.
Permit-ready report
You get the signed compliance certificates and checklists, ready to upload with your Barre building permit application.
Plan review support
If the building department asks for changes, we revise the report and answer the reviewer's questions.
REScheck & COMcheck for Barre Permits
Barre does things on paper. The Barre Building Department states that it does not accept permit applications or documents online or by email. Everything goes in as a hard copy, by mail or dropped off at the Henry Woods Building, 40 West Street. If you want documents returned, the department asks for a self-addressed stamped envelope. Office hours are Monday through Thursday, 7 AM to 4 PM.
That changes how we deliver your report. We still prepare the REScheck, COMcheck or HERS documents digitally, but we send them in a print-ready format so you can include signed copies with your Barre application.
Barre's energy code
Barre has been on the Massachusetts Stretch Code since January 1, 2012, and has not adopted the Specialized (Opt-In) Code. Here is how that plays out:
- A REScheck covers small residential additions and alterations where the prescriptive path is allowed, such as an addition up to 1,000 sq ft that is not more than 100% of the existing home.
- A new home needs a HERS rating, with a target of HERS 42 mixed-fuel or 45 all-electric.
- Larger renovations also need a HERS rating, at HERS 65 mixed-fuel or 70 all-electric.
- COMcheck documents commercial buildings, and commercial buildings over 20,000 sq ft need more than a COMcheck under the Stretch Code.
The nearest HEEC location to Barre is our Marlborough office at 272 Lincoln St C1. Call or email us with your plans and we will confirm which document your Barre project needs.
Basement and attic conversions that stay inside the existing footprint and roofline are usually REScheck projects too, which keeps smaller Barre jobs simple.
REScheck & COMcheck Questions for Barre Projects
Do I need a REScheck or a HERS rating in Barre?
Under the Massachusetts Stretch Code, new homes need a HERS rating (HERS 42 mixed-fuel or 45 all-electric) or Passive House. REScheck is used for additions of 1,000 sq ft or less that are not over 100% of the existing home, basement and attic conversions, and renovations. We confirm Barre's code status before we start.
When is a COMcheck required in Massachusetts?
A COMcheck documents commercial energy code compliance for new commercial buildings up to 20,000 sq ft (envelope, lighting and mechanical), for lighting and mechanical on larger buildings, and for commercial additions and alterations such as fit-outs, lighting changes and HVAC replacements. Massachusetts commercial code is based on the 2021 IECC with state amendments in 225 CMR 23.00.
What does a COMcheck include?
The COMcheck Envelope Compliance Certificate, the Interior and Exterior Lighting Compliance Certificates, the Mechanical Compliance Certificate, and the Plan Review Inspection Checklist. Massachusetts 225 CMR 23.00 Section C103.2 lists these as the construction-document requirements for buildings up to 20,000 sq ft.
What does a REScheck include?
A REScheck compares your home's envelope (insulation R-values and window U-values) to the code using a total UA trade-off, so stronger performance in one assembly can offset another. The report includes the compliance certificate and inspection checklist. Mandatory items such as air sealing and duct sealing still apply.
What size addition needs a HERS rating instead of REScheck?
In Massachusetts, a residential addition over 1,000 sq ft, or over 100% of the existing conditioned floor area, needs a HERS rating of the whole house (225 CMR 22.00 R502.1.1). Converting an existing basement or attic without changing the footprint or roofline does not.
What information do you need to prepare a REScheck or COMcheck?
Plans with wall, roof and floor sections, insulation types and R-values, the window and door schedule with U-factors and SHGC, and for commercial work the lighting fixture schedule with wattages, lighting controls, and HVAC and water heating equipment schedules.
Which software version is used in Massachusetts?
REScheck-Web with the 2023 Massachusetts Stretch Code option for residential, and COMcheck-Web set to the 2021 IECC (or ASHRAE 90.1-2019) for commercial, matching the code Massachusetts enforces.
How much does a REScheck or COMcheck cost in Barre?
REScheck reports start at $300 and COMcheck reports start at $600. The final price depends on the size of the project and how many assemblies and systems need to be entered. Send your plans for an exact quote.
Can I email my REScheck to the Barre Building Department?
No. The Barre Building Department does not accept permit applications or documents online or by email. Hard copies go by mail or are dropped off at the Henry Woods Building, 40 West Street. We provide print-ready reports for your package.
Is Barre on the Stretch Code?
Yes. The Massachusetts adoption list shows Barre on the Stretch Code since January 1, 2012. It has not adopted the Specialized (Opt-In) Code. New homes need a HERS rating (HERS 42 mixed-fuel or 45 all-electric).
