Non-residential, 50,000 gsf and larger
Interim standard December 31, 2028, final standard December 31, 2033.
Montgomery County, Maryland Building Energy Performance Standards
Montgomery County BEPS: the first interim standard is December 31, 2028.
Commercial and multifamily buildings of 25,000 gross square feet and larger must bring site energy use intensity down to a standard for their property type. Non-residential buildings of 50,000 gsf and larger meet the interim standard at the end of 2028 and the final standard at the end of 2033.
Who is covered
Around 1,850 buildings in the County, grouped by size and type.
Smaller non-residential and multifamily
Later groups, with interim deadlines from 2030. We confirm your group on the first call.
The metric
Site energy use intensity. The interim standard sits halfway between the building's baseline and its final standard.
How we help
Two years is enough time to close most gaps, if the measures are in place early.
BEPS gap check
Baseline, interim standard and the distance between them, from your benchmarking history.
Retro-commissioning
Controls, schedules, setpoints and sequences tuned and verified device by device. Usually the fastest and least costly way to cut energy use and emissions.
CommissioningEnergy audit and assessment
The audit and retrofit plan a Building Performance Improvement Plan requires, with a qualified auditor.

Where a standard is not economically feasible, a plan of cost-effective measures the County can approve.
Benchmarking support
Your June 1 report prepared from clean data, so the EUI the County sees is the real one.

Montgomery County BEPS questions
What is the metric?
Site energy use intensity, energy use per square foot. Compliance under the performance pathway uses normalized net site EUI.
How is my interim standard set?
Halfway between the building's baseline and the final standard for its property type. The baseline comes from the building's benchmarking history.
What if we cannot meet the standard?
If meeting it is not economically feasible or is beyond your control, you can apply for a Building Performance Improvement Plan, based on an energy audit and a plan of cost-effective measures.
What counts as cost-effective?
Measures that pay back within the life of the equipment, or within 10 years for specially designated buildings such as affordable housing.
Does the Maryland state BEPS also apply?
Maryland has its own statewide building energy performance standards. We check which requirements apply to your building on the first call.
