What does an ENERGY STAR score of 71 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 71 means the building performs better than about 71% of its national peers. BuildingCensus bands the score into report-card grades; 71 falls in band B — above median (70–84). It sits 4 points below 75, the threshold for ENERGY STAR certification. In Chicago, 35% 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. Park Alexandria Condominium Association's 62.9 kBtu/ft² across 418,371 sq ft works out to about 26.3 billion Btu (7,712 MWh-equivalent) in 2023. Its source EUI of 89.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,629,269 kWh of electricity, 207,576 therms of natural gas and 6,130 thousand gallons of water for the year.

Which law requires Park Alexandria Condominium Association to report its energy use?
