Benchmarking provides owners, tenants and operators with a greater understanding of their buildings' energy and water consumption.


If you own a building you may assign a representative in consultation with the building’s operating staff to benchmark your building’s energy use. When benchmarking is complete, you must electronically submit the report generated by the EPA's online tool - Portfolio Manager. Submit your report the results to the Department of Finance using the NYC portal.

If you received a Requirement to Benchmark Energy Usage notice from the Department of Finance or see your building on the list of buildings required to benchmark and believe this is inaccurate, or wish to dispute your building’s square footage or wish to dispute the number of buildings on a tax lot, contact the Department of Finance at If you are disputing the square footage of your building or the number of buildings on a tax lot, please include the following information in your email:

  • Your building’s borough, block and lot number
  • Your contact name
  • Your contact email address or telephone number
  • The reason you are disputing your building’s square footage
