How has Sm 4's energy performance changed over time?
BuildingCensus holds 2 Montgomery County disclosures for Sm 4, covering report years 2023–2024. Site EUI moved from 41.4 kBtu/ft² (2023) to 42.5 kBtu/ft² (2024), an 3% increase. Reported emissions went from 73 tCO₂e to 75 tCO₂e over the same span (up 4%).
What does a site EUI of 42.5 kBtu/ft² mean?
Site energy-use intensity (EUI) is the energy a building uses on site in a year divided by its floor area, in thousand Btu per square foot — lower is more efficient. Sm 4's 42.5 kBtu/ft² across 31,645 sq ft works out to about 1.3 billion Btu (394 MWh-equivalent) in 2024. Its source EUI of 50.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 32,122 kWh of electricity and 12,357 therms of natural gas for the year.
Which law requires Sm 4 to report its energy use?
Sm 4 reports under the Benchmarking Law (Bill 2-14) / BEPS (Bill 16-21), the legal basis of Montgomery County's Commercial Building Energy Benchmarking program, which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2024 disclosure (source record montgomery_county:54523592:2024).
