Nearly 80 percent of our citywide emissions are attributed to buildings’ energy use. Many new sustainable technologies have recently come to the marketplace that help offset these emissions, increase a building’s efficiency, decrease energy dependence, and reduce costs for homeowners. Here you will find resources that review these technologies, describe the benefits they offer, and explain how they can be used within New York City.
NOTE: The effective date for the 2020 NYC Energy Conservation Code was May 12, 2020.
Local Law 97 of 2019, passed by the City Council as part of Mayor Bill de Blasio’s Green New Deal, is an unprecedented commitment to increase the sustainability of buildings, the single-largest source of greenhouse gas (GHG) emissions in New York City. The law became effective on November 15, 2019.
Local Law 97 will further the goal of achieving a 40 percent reduction in aggregate greenhouse gas emissions from covered buildings by calendar year 2030 and an 80 percent reduction in citywide emissions by calendar year 2050.
