New Jersey Clean Energy Act

As of Oct. 1, 2023, all New Jersey commercial properties and buildings larger than 25,000 square feet are mandated to benchmark their energy and water consumption for 2022. Benchmarking enables building owners and property managers to measure, track and analyze energy and water consumption and compare their performance on each factor to that of other properties.

Benchmarking requirement

With the data obtained from benchmarking, owners and operators can assess opportunities for improvements that reduce water and energy consumption, as well as realize additional benefits in the form of energy cost savings, reductions in greenhouse gas (GHG) emissions and property appreciation.

The law defines a commercial property as any building with Class 4A (commercial) or Class 4C (apartment) tax assessment classifications. New Jersey provides a publicly available “Covered Buildings Spreadsheet” that can be consulted to determine whether a building or facility is covered under the mandate.

How do I comply with the New Jersey Clean Energy Act?

In order to comply with the law, submissions must be made using the ENERGY STAR® Portfolio Manager, a tool for tracking and assessing energy and water use that’s utilized by property owners and managers representing nearly 25 percent of US commercial building space.1

Covered buildings should have received a notification from the Board of Public Utilities by July 1, 2023. While there are no financial penalties for noncompliance at this time, the board has stated it may revisit the issue depending on the voluntary compliance level achieved.
