Building Energy Benchmarking
Energy benchmarking is the process of measuring a building’s energy use over time. This allows owners and occupants to understand their building’s energy performance relative to similar buildings and helps identify opportunities to cut energy waste.

Rockville property owners must comply with the Montgomery County Benchmarking Law:
  • Owners of certain types of non-residential buildings 50,000 square feet and greater, or a group of buildings that share a parcel (have the same Tax ID) that are collectively 50,000 square feet or greater, are required to benchmark energy use in ENERGY STAR Portfolio Manager; 
  • Data must be verified by a Recognized Data Verifier the first year and every three years thereafter; and
  • Report data to Montgomery County annually by June 1st for public disclosure.

Montgomery County Benchmarking Requirements and Resources
On July 11, 2016, the Mayor and Council amended the Rockville City Code to allow Montgomery County’s building energy benchmarking requirements to apply within the City of Rockville and be administered by Montgomery County Department of Environmental Protection. To comply with the law, please see Montgomery County's resources and requirements:                Energy Financial Resources
Owners of Rockville commercial properties can take advantage of financial incentives to adopt energy-efficient practices and renewable technologies. Incentives are available from utilities, as well as local, state, and federal sources.
