REScheck & COMcheck Greenfield MA
Home Energy Efficiency Consultants prepares REScheck (residential) and COMcheck (commercial) compliance documentation for Greenfield 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 Greenfield 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 Greenfield can confirm compliance quickly.
What is a COMcheck?
COMcheck handles commercial work and high-rise residential of four stories or more. The DOE tool evaluates envelope, lighting (interior and exterior), and mechanical systems against either the IECC or ASHRAE 90.1, with trade-offs allowed across components.
What is a REScheck?
For homes, REScheck is the go-to. This DOE program checks residential envelopes — detached houses and multifamily up to three stories — and allows insulation and fenestration trade-offs to show prescriptive or component-based IECC compliance.
REScheck Projects in Greenfield
REScheck is the simplest path for smaller residential projects in Greenfield 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
- Window and insulation upgrades that must be documented for a building permit
- Additions, alterations, or renovations to a one- or two-family home
- Projects where insulation and window trade-offs are enough to demonstrate compliance
Commercial Work That Needs a COMcheck in Greenfield
COMcheck is required for commercial and larger projects in Greenfield. Reach for a COMcheck when your project involves:
- Commercial buildings — offices, retail, restaurants, warehouses, and mixed-use
- Warehouse, industrial, and light-manufacturing conditioned spaces
- Tenant fit-outs and interior or exterior lighting alterations
- Envelope work on commercial structures requiring IECC or ASHRAE 90.1 compliance
- High-rise residential buildings of four stories or more
