Carbon Dioxide Emission Rates

Submitted by Charles Eley on Sat, 08/29/2020 - 00:00

ASHRAE has published carbon dioxide emission rates and source energy conversion factors for fuels used in buildings and for electricity use in each of the 26 EPA eGRID subregions. The updated figures result from a couple of years of work by Working Group 7.5 of Standard 189.1, which I chair. These data will be published in the 2020 release of Standard 189.1 and will become part of the 2021 update to the International Green Construction Code (IgCC). The source enrgy conversion factors take account of the increased renewable energy on the U.S.
