Reducing CO2 Emissions in NYC Buildings

Did you know that the majority of New York City’s CO2 emissions comes from buildings? Not exactly what you expected from an auto-dependent city? Heating, cooling, lighting, and general operations can use a vast amount of energy. To meet the goal of reducing carbon emissions by 30% before 2030, New York City is targeting energy reduction in the city’s largest buildings. Since 2010, buildings 50,000 sq. ft. and over have been required to benchmark their energy and water use as part of Local Law 84.

The Energy Locus map was created in collaboration with Mappler and the Community Mapping Initiative, a student interest group at the Edward J. Bloustein School of Planning and Public Policy, Rutgers. The map includes the 2011 EPA Energy Star score for hundreds of commercials buildings in New York City that were required to comply with Local Law 84.

This map allows users to search for addresses and determine a listing’s Energy Star Score. Buildings with a score of 75 and higher indicate the facility performs better than at least 75% of similar buildings nationwide when accounting for weather and operating conditions.
