This is a great idea. I always envisioned something like this being developed for the whole US for the purposes of whole building LCA baseline. Something like ASHRAE’s baseline for energy modeling but for LCA, which would need to be more specific, hence, it’s a little more complex. It would definitely be valuable! I am not sure about funding sources but I wonder how much this would overlap with KieranTimberlake’s LCA benchmark initiative, @Roderick_Bates?
@lindselove, what is your planned approach to gathering the assembly information and determining how common they are? Would you send out a survey to the local builders?
