New York City was the birthplace of the electrical grid. Today, our policy makers realize that the city’s survival depends on electrifying much more than lighting. But the heat pump transition has barely begun for the multifamily sector, which accounts for more than 30 percent of the city's carbon emissions from buildings. Urban Green, NYSERDA and a group of 30 heat pump experts are developing a roadmap for scaling heat pumps in NYC's large multifamily buildings. Financial and technical hurdles have kept archaic fossil fuel systems deeply rooted in multifamily buildings for decades. We have ideas on how to break this cycle and get owners and tenants onboard. Our project team will discuss practical solutions and explain our roadmap for electrifying the NYC multifamily building sector.
