Benchmarking Local Law 84 (LL84 of 2009): NYC   has   a self-reported   annual   building   energy   benchmarking   law   for   buildings   over   50,000   square   feet (SF).   The   data   is   logged in  the   Environmental   Protection   Agency’s   (EPA) ENERGY   STAR   Portfolio   Manager.   This   tool   compares   buildings   typologies   across   the nation   and   is   normalized   for   weather   and   usage   to   designate   a   score   based   on   a ranking   percentile. For this analysis a limitation is that many multi-family (MF) buildings are smaller than the 50,000 SF. However, because many people reside in larger MF, there are many residents impacted by the initiatives.
