REScheck vs. COMcheck: What’s the Difference?
REScheck and COMcheck are DOE-developed programs that show a building meets the IECC energy code. Which one your Mattapoisett 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 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.
Is a REScheck Right for Your Mattapoisett Project?
REScheck is the simplest path for smaller residential projects in Mattapoisett 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
- Multifamily buildings of three stories or fewer
- Finished basements, attic conversions, and dormer additions on existing homes
- Window and insulation upgrades that must be documented for a building permit
- Permit applications needing residential envelope documentation on the prescriptive or UA trade-off path
When Do You Need a COMcheck in Mattapoisett?
COMcheck is required for commercial and larger projects in Mattapoisett. Reach for a COMcheck when your project involves:
- Envelope work on commercial structures requiring IECC or ASHRAE 90.1 compliance
- High-rise residential buildings of four stories or more
- Warehouse, industrial, and light-manufacturing conditioned spaces
- Medical, dental, and professional office construction
- New mechanical (HVAC) or service water heating systems in commercial spaces
