NYC Accelerator is here to help you reduce costs in your building, improve occupant health and safety, and confront climate change. Our team of experts provide free, personalized guidance to make cost-saving, energy-efficiency upgrades and reduce carbon emissions across New York City's one million buildings. Since the NYC Mayor's Office of Sustainability launched the program in 2012, we have worked with thousands of buildings across the five boroughs to build a cleaner future by reducing pollution and cutting carbon emissions.
