REScheck & COMcheck Washington MA
Home Energy Efficiency Consultants prepares REScheck (residential) and COMcheck (commercial) compliance documentation for Washington projects. When your build does not trigger a full HERS rating, these DOE compliance reports are the fast, affordable path to your permit.
What we deliver
A stamped, signed compliance report matched to your plans and ready to upload with your Washington building permit application.
What Is a REScheck and What Is a COMcheck?
Both are free compliance software tools developed by the U.S. Department of Energy (DOE) to demonstrate that a building meets the International Energy Conservation Code (IECC). They document your envelope, and for commercial work your lighting and mechanical systems, so a plan reviewer in Washington can confirm compliance quickly.
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.
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 Washington?
REScheck is the simplest path for smaller residential projects in Washington 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
- Projects where insulation and window trade-offs are enough to demonstrate compliance
- Detached accessory structures with conditioned space
- Additions, alterations, or renovations to a one- or two-family home
- Finished basements, attic conversions, and dormer additions on existing homes
COMcheck Projects in Washington
COMcheck is required for commercial and larger projects in Washington. Reach for a COMcheck when your project involves:
- Warehouse, industrial, and light-manufacturing conditioned spaces
- Restaurant build-outs and retail white-box improvements
- Medical, dental, and professional office construction
- Commercial buildings — offices, retail, restaurants, warehouses, and mixed-use
- High-rise residential buildings of four stories or more
