What does an ENERGY STAR score of 78 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 78 means the building performs better than about 78% of its national peers. BuildingCensus bands the score into report-card grades; 78 falls in band B — above median (70–84). Scores of 75 or higher meet the threshold for ENERGY STAR certification; certification itself is a separate, verified application that the disclosure does not record. 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. Lois Rockville's 190.3 kBtu/ft² across 56,496 sq ft works out to about 10.8 billion Btu (3,151 MWh-equivalent) in 2024. Its source EUI of 405.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,942,794 kWh of electricity and 41,205 therms of natural gas for the year.

Which law requires Lois Rockville to report its energy use?

Lois Rockville 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:16895385:2024). 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.
