New York City, New York 

Population: 8.5 Million

New York City is the largest city in the Unites States, with more than 8.5 million residents and more than one million buildings. In 2014, NYC Mayor Bill de Blasio committed to reduce citywide greenhouse gas emissions by 80% from 2005 levels by 2050 (80x50). The city estimates that to achieve 80x50, every building must reduce energy use by 40% to 60%. Over half of these buildings must also convert to high-efficiency electric heating and more than 90% will need to electrify their domestic hot water.


Through detailed market segmentation, the city identified over 175,000 small residential buildings that are the best candidates for heating electrification in the near-term based on a combination of technical, market, and socio-demographic characteristics. The city is partnering with its electric and gas utility, Consolidated Edison, the New York State Energy Research and Development Authority (NYSERDA), and Mitsubishi Electric, one of the world’s largest manufacturers of heat pumps, to complete market research to develop coordinated engagement programs for customers and contractors in the city.


New York City will pilot heat pump installations in larger multi-family and commercial buildings under the NYC Retrofit Accelerator program. The City has also compiled a list of technology needs to improve existing heat pumps for the NYC market, and has begun working directly with manufacturers to identify opportunities to develop these new systems. As a result, New York City expects to begin to unlock its huge market to accelerate installations of high efficiency electric heat pumps and drive the long-term transformation away fossil fuel use in buildings.
