Today is the last day to replace your existing label with the latest energy efficiency score. Local Law 33 of 2018 requires all large building owners subject to the benchmarking law to display the energy grade of each building annually, in a clearly visible location. This year DOB delayed the posting period for owners of large buildings from Oct. 1 – Oct. 31 to Dec. 1 – Dec. 31. This extension applies only to the 2025 filing year. New labels are available on the DOB Now portal beginning Dec. 1.
