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 Harwich project needs depends on whether the work is residential or commercial — here is how they differ.
What is a REScheck?
REScheck is the DOE’s residential compliance tool. It covers one- and two-family dwellings and low-rise multifamily (three stories or fewer), using a UA trade-off so a stronger wall or roof can make up for a weaker window while the overall envelope still meets the IECC.
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.
REScheck Projects in Harwich
REScheck is the simplest path for smaller residential projects in Harwich 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
- Permit applications needing residential envelope documentation on the prescriptive or UA trade-off path
- Additions, alterations, or renovations to a one- or two-family home
- Detached accessory structures with conditioned space
- Finished basements, attic conversions, and dormer additions on existing homes
Commercial Work That Needs a COMcheck in Harwich
COMcheck is required for commercial and larger projects in Harwich. Reach for a COMcheck when your project involves:
- High-rise residential buildings of four stories or more
- New mechanical (HVAC) or service water heating systems in commercial spaces
- Commercial buildings — offices, retail, restaurants, warehouses, and mixed-use
- Restaurant build-outs and retail white-box improvements
- Warehouse, industrial, and light-manufacturing conditioned spaces
