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 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. Pine Grove Apartments's 101.4 kBtu/ft² across 100,338 sq ft works out to about 10.2 billion Btu (2,982 MWh-equivalent) in 2023. Its source EUI of 136.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 510,059 kWh of electricity, 84,336 therms of natural gas and 7 thousand gallons of water for the year.

Which law requires Pine Grove Apartments to report its energy use?

Pine Grove Apartments reports under the Building Energy Use Benchmarking Ordinance, the legal basis of the Chicago Energy Benchmarking program, which publishes each covered building's annual benchmarking results.
