What we deliver
A stamped, signed compliance report matched to your plans and ready to upload with your Wilmington building permit application.
Understanding REScheck and COMcheck
These are the two standard software tools plan reviewers accept for energy code compliance. Developed by the DOE, they let a Middlesex County project demonstrate that its envelope (and, for commercial, lighting and mechanical) 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.
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.
When Do You Need a REScheck in Wilmington?
REScheck is the simplest path for smaller residential projects in Wilmington 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
- Window and insulation upgrades that must be documented for a building permit
- Additions, alterations, or renovations to a one- or two-family home
- Permit applications needing residential envelope documentation on the prescriptive or UA trade-off path
- Projects where insulation and window trade-offs are enough to demonstrate compliance
Commercial Work That Needs a COMcheck in Wilmington
COMcheck is required for commercial and larger projects in Wilmington. 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
- Tenant fit-outs and interior or exterior lighting alterations
- Restaurant build-outs and retail white-box improvements
- Warehouse, industrial, and light-manufacturing conditioned spaces
