Overview

This local law requires buildings to meet the most current energy code for any renovation or alteration project. LL 85 filled a loop hole found in previous regulations by no longer exempting projects affecting less than 50% of the building from following the most current code standards. Through this law, the New York City Energy Conservation Code (NYCECC) was established in 2009. Since its enactment, additional amendments have been added to NYCECC to increase its strength and scope. These amendments include LL 48, mandating occupancy sensors in small, infrequently used commercial spaces (2010), the 2010 Energy Conservation Construction Code of New York State (ECCCNYS), and Local Law 1 (2011).
