What does an ENERGY STAR score of 12 mean?

ENERGY STAR scores run from 1 to 100 and are computed by the EPA's Portfolio Manager as a percentile against similar buildings nationwide, adjusted for climate, size and use: a score of 12 means the building performs better than about 12% of its national peers. BuildingCensus bands the score into report-card grades; 12 falls in band D — lowest band (1–54). It sits 63 points below 75, the threshold for ENERGY STAR certification. In Montgomery County, 53% of scored buildings are at 75 or above.

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. Crescent I's 88.9 kBtu/ft² across 25,020 sq ft works out to about 2.2 billion Btu (652 MWh-equivalent) in 2024. Its source EUI of 249.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 652,044 kWh of electricity and 0 therms of natural gas for the year.

Which law requires Crescent I to report its energy use?

Crescent I 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:22876629:2024). Montgomery County's BEPS (Bill 16-21; regulations approved in 2025) sets declining site-EUI standards for buildings of 25,000+ sq ft, with interim and then final standards later this decade and into the 2030s depending on building type.
