Available from the Department of Energy EERE Building Energy Codes Program, 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 available in two formats:

  • REScheck-Web™ accessible directly online with no installation; and
  • REScheck™ Desktop for Windows® downloaded and installed locally.

REScheck supported Codes:

  • 2009, 2012, 2015, 2018 AND 2021 IECC (2018 and 2021 in REScheck-Web only)
  • State Energy Codes: Florida, Massachusetts, New York City, Puerto Rico, Utah, Vermont (2020 MA, 2020 VT and 2017 DC in REScheck-Web only)
