REScheck & COMcheck Ashby MA
Need a REScheck or COMcheck in Ashby? We produce permit-ready energy code compliance reports for homes and commercial buildings across Middlesex County, matched precisely to your plans so your project clears plan review the first time.
What we deliver
A stamped, signed compliance report matched to your plans and ready to upload with your Ashby 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 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 Ashby Project?
REScheck is the simplest path for smaller residential projects in Ashby 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
- Finished basements, attic conversions, and dormer additions on existing homes
- Window and insulation upgrades that must be documented for a building permit
- Detached accessory structures with conditioned space
Commercial Work That Needs a COMcheck in Ashby
COMcheck is required for commercial and larger projects in Ashby. Reach for a COMcheck when your project involves:
- Commercial buildings — offices, retail, restaurants, warehouses, and mixed-use
- High-rise residential buildings of four stories or more
- Restaurant build-outs and retail white-box improvements
- Medical, dental, and professional office construction
- Warehouse, industrial, and light-manufacturing conditioned spaces
