Dept. of Energy’s REScheck tool updated for the 2021 International Energy Conservation Code

REScheck, a U.S. Department of Energy (DOE) software application that helps builders, designers, and contractors demonstrate that a particular home complies with the latest provisions of the International Energy Conservation Code, has been updated.

The new version, REScheck 2.1.0, supports the 2021 International Energy Conservation Code—the latest version. DOE has determined that the provisions of the 2021 IECC will achieve savings of 9.4% in residential buildings (compared to the 2018 edition).

REScheck, a web-based platform, doesn’t require any software installation. Builders, designers, and contractors use the tool to document and calculate whether new homes, additions, and alterations meet the requirements of the IECC as well as some state energy codes.

The 2021 IECC was released by the International Code Council (ICC) and affirmed by the Secretary of Energy earlier this year.
