REScheck & COMcheck Yarmouth MA
Home Energy Efficiency Consultants prepares REScheck (residential) and COMcheck (commercial) compliance documentation for Yarmouth 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 Yarmouth building permit application.
Understanding REScheck and 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 Yarmouth can confirm compliance quickly.
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 Yarmouth?
REScheck is the simplest path for smaller residential projects in Yarmouth 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
- Finished basements, attic conversions, and dormer additions on existing homes
- Detached accessory structures with conditioned space
- Multifamily buildings of three stories or fewer
- Additions, alterations, or renovations to a one- or two-family home
When Do You Need a COMcheck in Yarmouth?
COMcheck is required for commercial and larger projects in Yarmouth. Reach for a COMcheck when your project involves:
- Warehouse, industrial, and light-manufacturing conditioned spaces
- Medical, dental, and professional office construction
- New mechanical (HVAC) or service water heating systems in commercial spaces
- Envelope work on commercial structures requiring IECC or ASHRAE 90.1 compliance
- High-rise residential buildings of four stories or more
