New York City has pledged to reduce 80% of its greenhouse gas (GHG)
emissions by 2050 (in relation to 2005 levels). Since about two thirds
of the city’s emissions come from building’s energy use, understanding
the energy performance of the city’s buildings is vital to meet that
target. To gauge this energy efficiency performance in a fair
comparison, this paper develops a new scoring method to rank the
buildings in terms of energy efficiency based on benchmarking data from
Local Law 84 (LL84) and NYC Primary Land Use Tax Lot Output (PLUTO).
This scoring method is based on a model built predict the energy use
intensity (EUI) of each building and trained on data corresponding to
one specific year. Once the EUI is predicted, the score is calculated
from the ratio between predicted and actual EUI, which is then ranked by
percentile. As a result, every building receives a score to evaluate its
performance. The score is an attempt of making a fair comparison of
energy performance among buildings with different physical
characteristics, occupancy and use patterns, which will be sent to the
each building owner in a scorecard to inform their performance and
foster behavioral change towards a more efficient use of energy.
