48.3% of NYC’s buildings fail on energy efficiency according to Department of Buildings data


Energy efficiency among New York City buildings has improved a bit, but almost half of those forced to post a grade are still failing. According to The City’s analysis of preliminary data from the Department of Buildings, 48.3 percent of buildings received either a D or F grade. Receiving a D is essentially the worst a building can do, as Fs are reserved for properties that don’t submit data.

More than 20,000 buildings exceeding 25,000 square feet were surveyed. As reported by The Real Deal, the share of Ds dropped to 39.2 percent from 44.1 percent from the same time last year, indicating some of the least energy-efficient buildings made improvements. The share of F grades, however, increased from 7.6 to 9.1 percent. 

The grades are calculated based on an Energy Star metric comparing the energy consumption of buildings across the country with those of similar densities and uses. While landlords currently do not get fined for poor grades, beginning in 2024, Local Law 97 will subject building owners to a fine of $268 per ton of greenhouse gas emissions above a certain limit.
