REScheck & COMcheck Marlborough MA
Need a REScheck or COMcheck in Marlborough? We produce permit-ready energy code compliance reports for homes and commercial buildings across Middlesex County, matched precisely to your plans so your project clears plan review the first time.
What we deliver
A stamped, signed compliance report matched to your plans and ready to upload with your Marlborough building permit application.
Understanding REScheck and 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 Marlborough can confirm compliance quickly.
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.
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.
Is a REScheck Right for Your Marlborough Project?
REScheck is the simplest path for smaller residential projects in Marlborough 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
- Finished basements, attic conversions, and dormer additions on existing homes
- Permit applications needing residential envelope documentation on the prescriptive or UA trade-off path
- Projects where insulation and window trade-offs are enough to demonstrate compliance
COMcheck Projects in Marlborough
COMcheck is required for commercial and larger projects in Marlborough. Reach for a COMcheck when your project involves:
- Commercial buildings — offices, retail, restaurants, warehouses, and mixed-use
- Tenant fit-outs and interior or exterior lighting alterations
- High-rise residential buildings of four stories or more
- Medical, dental, and professional office construction
- Warehouse, industrial, and light-manufacturing conditioned spaces
