The Montgomery County Department of Environmental Protection (DEP) has released the first year of building energy data for County buildings larger than 50,000 square feet. This is the first release of data, required under the County’s Building Energy Benchmarking and Transparency Law.

The data, which provides information on 14 County facilities totaling more than 1.9 million square feet, is available at

Benchmarking and transparency laws are established to assist the commercial building market in reducing energy use and enhancing building operations. By comparing one building’s energy use against comparable buildings across the Country, facility owners can improve energy performance, identify energy efficiency opportunities, and drive down utility costs over time.

Applying data to achieve measurable outcomes is essential to the Department of General Services’ (DGS’) approach to managing energy,” said David Dise, Director of DGS. “Better understanding the energy consumption patterns of our buildings helps the County prioritize investment resulting in energy saving projects with the greatest greenhouse gas emissions reductions and cost savings to our taxpayers.”

In April 2014, Montgomery County became the first county in the nation to adopt a building energy benchmarking and disclosure law for public County buildings and certain private commercial buildings that are greater than 50,000 square feet. Currently, using benchmarking and other means, the County has identified more than 15 major energy efficiency projects in its buildings, including three facilities covered under the Benchmarking Law.


“Through the Benchmarking Law, we anticipate Montgomery County’s building stock will improve in an efficient and sustainable way,” said Lisa Feldt, director of DEP. “The County has an ambitious goal to reduce greenhouse gas emissions 80 percent by the year 2050, and our government and commercial building community is a key component towards achieving that goal. It is important that Montgomery County government lead by example. We applaud the partnership with DGS to reduce our greenhouse gas emissions and address the challenge of climate change.”

    Where can I find the most up-to-date on green energy benchmarking for county owned buildings and fleet vehicles?

    1. Hi Patricia, thank you for your question about County building energy benchmarking data and fleet data. We emailed you and we are including the information here too, in case anyone else has the same question.

      The calendar year 2016 benchmarking data for County buildings should be released in the next week or so. Once it is available, we’ll send out a notice on the Commercial Energy News email list, which is the monthly newsletter for all things Benchmarking Law related and of interest to green building/commercial energy professionals. The County Public Information Office will also distribute a press release.

      The Department of Environmental Protection doesn’t manage the County’s fleet or data related to the fleet. You can reach out to Fleet Management Services within the Department of General Services by sending an email to

      Thanks for your question!
