My biggest question about v4.1 right now is whether or not the benchmarking that takes place for the LT and EA prerequisites is transparent. Is there any way we can estimate a building's performance before registering for the rating system? I foresee most clients balking at the prospect of paying to register for a rating system when they have no idea if they'll qualify for the prerequisites. Previously, it was trivial to enter 12 months of data into Portfolio Manager and estimate a score.
At first blush, I support the move to use carbon as a more meaningful metric in LEED. But without transparency around the data set that is used for benchmarking, how can we have confidence that it is truly meaningfully implemented?
