Dive Brief:

• In the last days of the Bloomberg administration, New York City has issued energy consumption data for its largest residential buildings for the first time. 
• Each building has received a letter grade, with each grade reflecting how much energy each building uses per square foot.
• This is the first time a U.S. city has published energy use data like this, environmental groups have observed.

Dive Insight:

The city's survey looks at more than 26,600 buildings covered by a 2009 law advocated by outgoing Mayor Michael Bloomberg. The publishing of the data allows residents to compare their buildings' energy consumption with others. For example, some of Manhattan's newer residential addresses that market themselves as "green" actually received "D" grades.
