What does an ENERGY STAR score of 62 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 62 means the building performs better than about 62% of its national peers. BuildingCensus bands the score into report-card grades; 62 falls in band C — below median (55–69). It sits 13 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. 555 Thayer Associates, Ltd Partnership's 65.0 kBtu/ft² across 99,180 sq ft works out to about 6.4 billion Btu (1,889 MWh-equivalent) in 2024. Its source EUI of 105.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 617,515 kWh of electricity and 43,355 therms of natural gas for the year.
