What does an ENERGY STAR score of 89 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 89 means the building performs better than about 89% of its national peers. BuildingCensus bands the score into report-card grades; 89 falls in band A — high performer (85–100). Scores of 75 or higher meet the threshold for ENERGY STAR certification; certification itself is a separate, verified application that the disclosure does not record. 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. 1720 South Michigan Condominium Association's 63.0 kBtu/ft² across 528,647 sq ft works out to about 33.3 billion Btu (9,761 MWh-equivalent) in 2023. Its source EUI of 103.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,294,121 kWh of electricity and 220,904 therms of natural gas for the year.

Which law requires 1720 South Michigan Condominium Association to report its energy use?
