What does an ENERGY STAR score of 44 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 44 means the building performs better than about 44% of its national peers. BuildingCensus bands the score into report-card grades; 44 falls in band D — lowest band (1–54). It sits 31 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. The Met Rockville's 49.9 kBtu/ft² across 243,000 sq ft works out to about 12.1 billion Btu (3,554 MWh-equivalent) in 2024. Its source EUI of 139.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,556,963 kWh of electricity and 0 therms of natural gas for the year.
