There were multiple proposals considered this week to add Life Cycle Assessment (LCA) provisions to the International Green Construction Code (IgCC). The only one that was approved was one that just added a definition of LCA. Proposals that required evaluation of characteristics such as Acidification, Eutrophication, Smog Potential, Ozone Deplection Potential and Primary Energy Use were all disapproved.
According to the testifiers at the hearings scientists around the world agree on how to measure these characteristics. Unfortunately this information had not been shared in the form of proposed code text. Therefore requirements for their measurement were determined to be vague and unenforceable.
