The U.S. Department of Energy (DOE) released its preliminary determination of energy savings for ANSI/ASHRAE/IES Standard 90.1-2019.
The study affirmed that the updated code will increase energy efficiency in commercial buildings. The analysis, performed by Pacific Northwest National Laboratory (PNNL), indicates that buildings meeting Standard 90.1-2019 (as compared to the previous 2016 edition) would result in national average energy savings of about:
· 4.7% site energy
· 4.3% source energy
· 4.3% energy cost
· 4.2% carbon emissions
DOE will accept written comments and information on the analysis through May 21, 2021.
