Abstract: Since 2009, New York City's Local Law 84 (LL84) has required both city-owned and private buildings of a certain size to report their actual (not calculated) annual energy and water use. This paper summarizes the LL84 data available at the time of this study, including the scope and quality of the reported data. We cross-reference the LL84 database with the database of known LEED-certified buildings in NYC to see how well LEED-certified buildings perform in comparison to non-LEED buildings. The validity of performing such a comparison based on the information currently available is discussed. We also provide a general review of how energy codes and standards have evolved over time, and how they may be affecting the trends in energy use data.
