REScheck vs. COMcheck: What’s the Difference?
These are the two standard software tools plan reviewers accept for energy code compliance. Developed by the DOE, they let a Middlesex County project demonstrate that its envelope (and, for commercial, lighting and mechanical) meets the IECC.
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 Winchester
REScheck is the simplest path for smaller residential projects in Winchester 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
- Multifamily buildings of three stories or fewer
- Finished basements, attic conversions, and dormer additions on existing homes
- Additions, alterations, or renovations to a one- or two-family home
When Do You Need a COMcheck in Winchester?
COMcheck is required for commercial and larger projects in Winchester. Reach for a COMcheck when your project involves:
- New mechanical (HVAC) or service water heating systems in commercial spaces
- Restaurant build-outs and retail white-box improvements
- Warehouse, industrial, and light-manufacturing conditioned spaces
- Tenant fit-outs and interior or exterior lighting alterations
- Envelope work on commercial structures requiring IECC or ASHRAE 90.1 compliance
