Understanding REScheck and COMcheck
REScheck and COMcheck are DOE-developed programs that show a building meets the IECC energy code. Which one your Grafton project needs depends on whether the work is residential or commercial — here is how they differ.
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.
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.
When Do You Need a REScheck in Grafton?
REScheck is the simplest path for smaller residential projects in Grafton 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
- Detached accessory structures with conditioned space
- 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
COMcheck Projects in Grafton
COMcheck is required for commercial and larger projects in Grafton. Reach for a COMcheck when your project involves:
- Tenant fit-outs and interior or exterior lighting alterations
- Medical, dental, and professional office construction
- New mechanical (HVAC) or service water heating systems in commercial spaces
- Warehouse, industrial, and light-manufacturing conditioned spaces
- Commercial buildings — offices, retail, restaurants, warehouses, and mixed-use
