A STUDY OF ENERGY USE IN NEW YORK CITY AND LEED-CERTIFIED BUILDINGS
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.
