REScheck & COMcheck Waltham MA
Fast, accurate REScheck and COMcheck energy code compliance reports for residential and commercial projects in Waltham, Massachusetts. We prepare the documentation your building department needs to issue a permit — without the cost of a full performance-path energy rating when your project does not require one.
What we deliver
A stamped, signed compliance report matched to your plans and ready to upload with your Waltham 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 Waltham 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 Waltham?
REScheck is the simplest path for smaller residential projects in Waltham 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
- Permit applications needing residential envelope documentation on the prescriptive or UA trade-off path
- Finished basements, attic conversions, and dormer additions on existing homes
- Detached accessory structures with conditioned space
- Additions, alterations, or renovations to a one- or two-family home
COMcheck Projects in Waltham
COMcheck is required for commercial and larger projects in Waltham. Reach for a COMcheck when your project involves:
- Warehouse, industrial, and light-manufacturing conditioned spaces
- Tenant fit-outs and interior or exterior lighting alterations
- Medical, dental, and professional office construction
- Envelope work on commercial structures requiring IECC or ASHRAE 90.1 compliance
- Restaurant build-outs and retail white-box improvements
