Understanding REScheck and COMcheck
REScheck and COMcheck are DOE-developed programs that show a building meets the IECC energy code. Which one your Mendon 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?
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.
When Do You Need a REScheck in Mendon?
REScheck is the simplest path for smaller residential projects in Mendon 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
- Additions, alterations, or renovations to a one- or two-family home
- Detached accessory structures with conditioned space
- Projects where insulation and window trade-offs are enough to demonstrate compliance
- Multifamily buildings of three stories or fewer
COMcheck Projects in Mendon
COMcheck is required for commercial and larger projects in Mendon. Reach for a COMcheck when your project involves:
- Medical, dental, and professional office construction
- Restaurant build-outs and retail white-box improvements
- Warehouse, industrial, and light-manufacturing conditioned spaces
- Tenant fit-outs and interior or exterior lighting alterations
- New mechanical (HVAC) or service water heating systems in commercial spaces
