What Is a REScheck and What Is a COMcheck?
REScheck and COMcheck are DOE-developed programs that show a building meets the IECC energy code. Which one your Westford project needs depends on whether the work is residential or commercial — here is how they differ.
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.
What is a COMcheck?
COMcheck is DOE software for commercial buildings and high-rise residential (four stories or more). It checks the building envelope, interior and exterior lighting, and mechanical systems against the IECC or ASHRAE Standard 90.1, and can trade off components across the design.
REScheck Projects in Westford
REScheck is the simplest path for smaller residential projects in Westford 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
- Projects where insulation and window trade-offs are enough to demonstrate compliance
- Detached accessory structures with conditioned space
- Additions, alterations, or renovations to a one- or two-family home
- Finished basements, attic conversions, and dormer additions on existing homes
COMcheck Projects in Westford
COMcheck is required for commercial and larger projects in Westford. Reach for a COMcheck when your project involves:
- Restaurant build-outs and retail white-box improvements
- Medical, dental, and professional office construction
- Warehouse, industrial, and light-manufacturing conditioned spaces
- High-rise residential buildings of four stories or more
- Tenant fit-outs and interior or exterior lighting alterations
