REScheck & COMcheck East Longmeadow MA
Home Energy Efficiency Consultants prepares REScheck (residential) and COMcheck (commercial) compliance documentation for East Longmeadow projects. When your build does not trigger a full HERS rating, these DOE compliance reports are the fast, affordable path to your permit.
What we deliver
A signed compliance report matched to your plans and ready to upload with your East Longmeadow 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 East Longmeadow can confirm compliance quickly.
What is a REScheck?
REScheck is the DOE’s residential compliance tool. It covers one- and two-family dwellings and low-rise multifamily (three stories or fewer), using a UA trade-off so a stronger wall or roof can make up for a weaker window while the overall envelope still meets the IECC.
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.
REScheck Projects in East Longmeadow
REScheck is the simplest path for smaller residential projects in East Longmeadow that do not need a HERS rating. It is typically the right tool for:
- New residential construction or an addition of 1,000 sq ft or less that does not require a HERS rating
- Projects where insulation and window trade-offs are enough to demonstrate compliance
- Additions, alterations, or renovations to a one- or two-family home
- Finished basements, attic conversions, and dormer additions on existing homes
- Permit applications needing residential envelope documentation on the prescriptive or UA trade-off path
COMcheck Projects in East Longmeadow
COMcheck is required for commercial and larger projects in East Longmeadow. Reach for a COMcheck when your project involves:
- Envelope work on commercial structures requiring IECC or ASHRAE 90.1 compliance
- Warehouse, industrial, and light-manufacturing conditioned spaces
- New mechanical (HVAC) or service water heating systems in commercial spaces
- Medical, dental, and professional office construction
- High-rise residential buildings of four stories or more

Which Energy Code Report Does a East Longmeadow Project Need?
East Longmeadow is not one of the 60 Massachusetts communities on the Specialized Code, so projects follow the Massachusetts Stretch Code (225 CMR 22.00 and 23.00), which 242 communities have adopted, or the base energy code if East Longmeadow has not adopted the Stretch Code. We confirm East Longmeadow's current code status against the state list before we prepare any report.
| Your East Longmeadow 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. East Longmeadow is in Hampden County, served from our Marlborough (272 Lincoln St) office.

REScheck & COMcheck Questions for East Longmeadow Projects
Do I need a REScheck or a HERS rating in East Longmeadow?
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 East Longmeadow'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 East Longmeadow?
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.
