Local Law 84 requires large buildings in New York City to track and report energy and water use annually through an automated benchmarking system developed by the NYC Environmental Protection. The system analyzes data from over 2.6 billion square feet of privately owned properties and 260 million square feet of public properties using automated meter reading. It provides accurate benchmarking data free of charge while protecting customer privacy and aims to identify opportunities for efficiency improvements and cost savings through comparisons of energy usage across different building types.
