What does an ENERGY STAR score of 61 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 61 means the building performs better than about 61% of its national peers. BuildingCensus bands the score into report-card grades; 61 falls in band C — below median (55–69). It sits 14 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. Westlake Park Condominium A's 32.9 kBtu/ft² across 95,494 sq ft works out to about 3.1 billion Btu (921 MWh-equivalent) in 2024. Its source EUI of 92.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 919,566 kWh of electricity and 0 therms of natural gas for the year.

Which law requires Westlake Park Condominium A to report its energy use?
