Energy audit data for privately owned buildings larger than 50,000 ft2, submitted by property owners in compliance with Local Law 87 of 2009. This data includes equipment inventory and recommended Energy Conservation Measures (ECMs) for base building systems: the building envelope, HVAC systems, elevators and escalators, domestic hot water supply, and electrical and lighting systems. This data does not include equipment owned by tenants or used for industrial processes within the building. This data represents energy audits collected between 2012 and 2018 using the City’s original, MS Excel-based, Energy Efficiency Report tool.
