BENCHMARKING STUDY HIGHLIGHTS ENERGY DECLINE
ity-wide energy use per building is on the decline, ac-
cording to the third annual New York City benchmark-
Covering the energy consumption of the city’s
largest properties in 2012, the fall 2014 report notes a
significant change in energy data from the previous two years. The
variance is at least partially attributable to outside factors, includ-
ing the widespread outages, electrical and mechanical damage, and
losses incurred during Hurricane Sandy.

Distribution of Energy Use Intensity
In Year Three, multifamily properties had a median EUI of 121, lower than the national
median source EUI of 130 for the Residential Energy Consumption Survey (RECS)
2005 database. Office properties reported at the median EUI of 191, also lower than
the Northeastern Region median source EUI of 210 for the Commercial Building
Energy Consumption Survey (CBECS) 2003 database (Fig. 18).

However, the 2012 data does validate the success of NYC Clean Heat,
a city program seeking to eliminate the use of heavy fuel oil. The
initiative accelerated fuel oil conversions in buildings affected by the
ban “well in advance of the actual deadlines,” helping to dramatically
reduce particulate matter measurements, the study observes.
The third year of reporting also saw an increase in compliance
– 84%, compared to 75% in the previous two years, with 92% of
the compliant building owners from the second year continuing
to comply this time. This is likely due to increasing familiarity with
the benchmarking requirements and ongoing efforts by utilities to
streamline aggregated data requests, the study predicts. Manhattan
again had the highest percentage of compliant buildings, with 87%
of its 5,705 eligible buildings filing the required information; Staten
Island had the lowest compliance for the third year in a row with just
67% of its 220 buildings participating. This year’s data was collected
from 20,320 private sector buildings covering 2. 3 billion square feet
and 3,097 public ones covering 281 million square feet.
The benchmarking law also requires water consumption for properties equipped with an automated meter reading (AMR) device for
a full calendar year – in 2012, this included 5,385 properties, roughly
40% of all that were covered. There is not yet enough data to compare New York City’s water use to previous years. However, comparisons with the water data set from the EPA’s Portfolio Manager reveal
that the city’s median water use intensity ratings tend to be higher
than the national average, with the exception of hotels.
Future reports will include expanded building information courtesy of Local Law 87, which mandates periodic energy audits and
retrocommissioning reports for buildings over 50,000 square feet.
These reports, intended to shed more light on energy consumption
and highlight efficiency opportunities, are required every 10 years.
Additionally, Local Law 88 requires large commercial building owners to install submeters in non-residential tenant space, which will
generate more data and grant greater control over energy use and
costs to tenants.
IN YEAR THREE, multifamily properties boasted a mean energy
use intensity (EUI) of 121, lower
than the national median of 130
for residential. Office properties
reported a median of 191, lower
than the regional commercial
median of 210.
