NYC Local Law 85 establishes the New York City Energy Conservation Code and eliminates a former loophole that permitted no energy efficiency improvements if the renovation applied to less than 50% of a building’s systems.

This requires buildings to meet the most current energy code for any renovation or alteration project. LL85’s requirement is based on a series of local energy laws, collectively called New York City Energy Conservation Code (NYCECC)

For all additions, alterations, renovations and repairs to an existing building or building system, the work must meet the current standards of the NYC Energy Conservation Code (NYCECC) at the time of construction.

Unless building energy use is increased as a result, the following building alterations need not comply with this code: storm windows installed over existing fenestration, replacements of glass in an existing sash and frame, construction where the existing roof, wall or floor cavity is not exposed, and existing ceiling, wall or floor cavities exposed during construction if filled with insulation.

A professional statement signed by a registered design professional (professional engineer, PE or registered architect, RA) or lead energy professional stating that the plans and specifications as installed are in compliance with the New York City Energy Conservation Code must be filed with the Department of Buildings.

During the initial application for the project, an energy analysis demonstrating the design’s compliance with the NYCECC, along with supporting documentation, must be provided. Contact us for Local Law 85 Support
