Embodied vs Operational LCA ghg emissions messaging..?

4

One of the common assumptions among designers that I see while working on projects, even the high performance ones that are aiming for Arch 2030 targets, is that low EUI means low emissions. In the past, we didn’t often take the extra step to analyze the regional grid mix, so the actual emissions remained hidden. Traditional LEED (v4 and earlier) calculations reinforced this bias with energy savings measured in cost. So we’re making sure now to do the “extra” step to reveal the full picture. I’m sure this is common knowledge among the forum…just sharing here that a lot of designers stop at EUI. We need to go much further in our analysis as a rule to understand buildings’ impacts beyond the property line.
