What does an ENERGY STAR score of 23 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 23 means the building performs better than about 23% of its national peers. BuildingCensus bands the score into report-card grades; 23 falls in band D — lowest band (1–54). It sits 52 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. Mahalia Jackson Apt's 187.0 kBtu/ft² across 103,330 sq ft works out to about 19.3 billion Btu (5,663 MWh-equivalent) in 2022. Its source EUI of 258.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 946,318 kWh of electricity and 138,180 therms of natural gas for the year.

Which law requires Mahalia Jackson Apt to report its energy use?

Mahalia Jackson Apt 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. The record shown here is the report-year 2022 disclosure (source record chicago:159982:2022). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
