What does an ENERGY STAR score of 19 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 19 means the building performs better than about 19% of its national peers. BuildingCensus bands the score into report-card grades; 19 falls in band D — lowest band (1–54). It sits 56 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. Ambassador House Condominium Association's 96.5 kBtu/ft² across 191,825 sq ft works out to about 18.5 billion Btu (5,425 MWh-equivalent) in 2023. Its source EUI of 145.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,405,826 kWh of electricity and 137,158 therms of natural gas for the year.

Which law requires Ambassador House Condominium Association to report its energy use?

Ambassador House Condominium Association 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.
