BuildingCensus holds 2 Montgomery County disclosures for Sg 9, covering report years 2023–2024. Site EUI moved from 65.2 kBtu/ft² (2023) to 60.0 kBtu/ft² (2024), a 8% decrease. Reported emissions went from 351 tCO₂e to 329 tCO₂e over the same span (down 6%).
What does a site EUI of 60.0 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. Sg 9's 60.0 kBtu/ft² across 66,440 sq ft works out to about 4 billion Btu (1,168 MWh-equivalent) in 2024. Its source EUI of 152.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 994,392 kWh of electricity and 5,968 therms of natural gas for the year.
Which law requires Sg 9 to report its energy use?
Sg 9 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:54544992:2024).
