Residential Compliance Using REScheck

The REScheck materials have been developed to simplify and clarify code compliance with the Model Energy Code (MEC), the International Energy Conservation Code (IECC), and a number of state codes.

The REScheck residential compliance materials offer two ways to demonstrate compliance: the trade-off approach and the prescriptive packages approach.

Trade-off Approach

The REScheck software simplifies energy code compliance by automating the trade-off calculations for this approach.

The REScheck-Web online code compliance tool can also be used to show compliance using the trade-off approach. It performs just like the desktop version but requires no download or installation. REScheck can be used in states that require the MEC/IECC as their energy code for residential buildings.

The following states/jurisdictions have their own state-specific versions of REScheck, that include state-specific example files and contact information:

  • Arkansas
  • Georgia
  • New Hampshire
  • New York
  • Vermont
  • Wisconsin
  • and Pima County, Arizona

Prescriptive Approach

The REScheck Package Generator is a web-based application that allows you to generate your own code-compliant insulation and window packages rather than following pre-defined prescriptive packages.

The 2009 IECC residential prescriptive requirements are provided in a county drill-down map. The 2009 IECC is the residential code that must be met in order to qualify for federal stimulus tax credits.
