Energy Management Success Stories: Demand Side Energy Management Strategies at NYC Health + Hospitals


Over the last decade, New York City (NYC) has instituted polices and measures to curtail energy consumption and mitigate the greenhouse gas (GHG) emissions that contribute to climate change. NYC Mayor De’Blasio has committed to reducing its GHG emissions 80% by 2050, compared to 2005 levels.
NYC Health + Hospitals is the largest integrated municipal healthcare system in the country. It is comprised of eleven acute care facilities, five skilled nursing facilities and six diagnostic and treatment centers. Over the last four years, NYC Health + Hospitals has implemented a combination of strategies and technologies designed to curtail energy consumption at facilities.

This presentation will evaluate the challenges and effectiveness of one such initiative –Demand Side Energy Management (DSEM), within a large healthcare system. Our discussion will provide a healthcare perspective to the DSEM technologies applied and cost of applying each technology. In addition, we will examine how the technologies were able to contribute to a 30% reduction of GHG emissions in 2018 over the base year 2007, and how these will further our efforts to achieve out 50% GHG emissions reduction goal by 2025.
