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.
