Sounds like a good study, it’s important to give our clients the best available, regionally relevant info on carbon emissions. And 33 is a good EUI as well, much better than many buildings, so energy-related carbon emissions may be underreported in many cases compared to your study. As a reference for everyone else, the US average GHG is in the 800s, well below the 1300 lbCO2e/MWh dirty grid in the study. https://www.epa.gov/egrid/power-profiler#/ You can find your region easily in the link.
As another reference, the US electricity grid has decreased carbon intensity by more than 35% since the peak around 15 years ago.
We need urgent action on all strategies, embodied and operational. For energy, we need ‘efficient electrification’ that includes heat pumps (2x-3x more efficient than electric resistance or gas, sometimes up to 6x) to reduce carbon emissions from electricity.
