How NYC Building Energy Grades Are Calculated (And Why They Matter)

Walk into a large residential or commercial building in New York City and you may see a letter grade posted near the entrance: A, B, C, D, or F.

That grade is not decorative. It represents your building’s publicly disclosed energy performance.

Under NYC regulations, buildings over 25,000 square feet are assigned an annual energy efficiency grade under Local Law 95, using data submitted through Local Law 84 filings. The grade must be displayed prominently where tenants, visitors, lenders, and inspectors can see it.
