The 2021 International Energy Conservation Code
The 2021 International Energy Conservation Code (IECC) is regarded by many as a significant achievement in building energy efficiency compared to the prior two code cycles (IECC 2015 and IECC 2018). An initial U.S. Department of Energy determination estimates a national average of 9.38 percent site energy savings and 8.66 percent energy cost savings compared to the 2018 IECC, with variance dependent upon climate zones.
NEEP has released the following one-pager and modules concerning key changes to the 2021 IECC model code relative to the previous edition, the 2018 IECC. These high-level overview video modules are intended for informational purposes only and are not recommended to be used for training or compliance.
