Modeling Operational Carbon Emissions with the HERS Carbon Index

In 2022, RESNET published the third edition of its ANSI/RESNET/ICC Standard 301, which now includes a new CO2e Index. This first-of-its-kind index is based on hourly forward-looking CO2 emissions data from the National Renewable Energy Laboratory’s Cambium Database. The CO2e Index combines hourly energy simulations in RESNET®’s accredited software programs with Cambium’s hourly emissions data to provide a new metric that values when energy is used. This session will provide an overview of how the CO2e index works and show examples of how HERS® Index scores compare to CO2e Index scores.
