Residential Compliance Using REScheck™
The REScheck product group makes it fast and easy for builders, designers, and contractors to determine whether new homes, additions, and alterations meet the requirements of the IECC or a number of state energy codes. REScheck also simplifies compliance determinations for building officials, plan checkers, and inspectors by allowing them to quickly determine if a low-rise residence meets the code.
REScheck is appropriate for insulation and window trade-off calculations in residential detached one- and two-family buildings and multi-family buildings three stories or less in height above grade, such as apartments, condominiums, and townhouses. REScheck works by performing a simple U-factor x Area (UA) calculation for each building assembly to determine the overall UA of a building. The UA that would result from a building conforming to the code requirements is compared against the UA for your building. If the total heat loss (represented as a UA) through the envelope of your building does not exceed the total heat loss from the same building conforming to the code, the software generates a report that declares your building is compliant with the code.
REScheck Desktop can be downloaded and installed directly to your desktop, while REScheck-Web™ is accessible directly from the website without having to download and install.
REScheck™ for Windows®
Runs on Windows 7/8/10 in either single, multi-user, or network environments.
Note that the Mac version of REScheck has been discontinued. Mac users are advised to use REScheck-Web
Version 4.6.4 (build version 188.8.131.52)
REScheck version 4.6.4 corrects the U-factor requirements applied to crawl walls in climate zones 5-8 of 2015 IECC and 2016 New York City. Further, it includes a correction to 2016 New York City code that discontinues enforcement of the prescriptive SHGC requirement when using the C405 performance methodology.
2009, 2012 and 2015 IECC
Various state and county energy codes.
REScheck-Web simplifies residential energy code compliance by automating tradeoff calculations for the IECC and a number of state-specific codes. It performs just like the REScheck desktop version, but you don't need to download or install any software on your computer.

Updates to REScheck and COMcheck Building Energy Code Compliance Software
The U.S. Department of Energy (DOE) is directed to provide technical assistance to states to support the implementation of model residential and commercial building energy codes (42 USC 6833). As part of this assistance, the DOE Building Energy Codes Program provides ongoing support for REScheck and COMcheck compliance software, which are updated based on new editions of the model codes. DOE has published guidance surrounding its support for the software, including technical assistance requests for modified versions.
