Data:
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.
