What Is a REScheck and What Is a COMcheck?
REScheck and COMcheck are DOE-developed programs that show a building meets the IECC energy code. Which one your Falmouth 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 Falmouth?
REScheck is the simplest path for smaller residential projects in Falmouth 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
- Multifamily buildings of three stories or fewer
- Finished basements, attic conversions, and dormer additions on existing homes
- Projects where insulation and window trade-offs are enough to demonstrate compliance
When Do You Need a COMcheck in Falmouth?
COMcheck is required for commercial and larger projects in Falmouth. Reach for a COMcheck when your project involves:
- New mechanical (HVAC) or service water heating systems in commercial spaces
- Envelope work on commercial structures requiring IECC or ASHRAE 90.1 compliance
- Commercial buildings — offices, retail, restaurants, warehouses, and mixed-use
- Warehouse, industrial, and light-manufacturing conditioned spaces
- High-rise residential buildings of four stories or more
