REScheck & COMcheck Westport MA
Fast, accurate REScheck and COMcheck energy code compliance reports for residential and commercial projects in Westport, 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 Westport 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 Westport 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 the DOE’s residential compliance tool. It covers one- and two-family dwellings and low-rise multifamily (three stories or fewer), using a UA trade-off so a stronger wall or roof can make up for a weaker window while the overall envelope still meets the IECC.
Is a REScheck Right for Your Westport Project?
REScheck is the simplest path for smaller residential projects in Westport 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
- Permit applications needing residential envelope documentation on the prescriptive or UA trade-off path
- Multifamily buildings of three stories or fewer
- Detached accessory structures with conditioned space
When Do You Need a COMcheck in Westport?
COMcheck is required for commercial and larger projects in Westport. Reach for a COMcheck when your project involves:
- Warehouse, industrial, and light-manufacturing conditioned spaces
- New mechanical (HVAC) or service water heating systems in commercial spaces
- Commercial buildings — offices, retail, restaurants, warehouses, and mixed-use
- Envelope work on commercial structures requiring IECC or ASHRAE 90.1 compliance
- Tenant fit-outs and interior or exterior lighting alterations
