How has Grace St.'s energy performance changed over time?

Its ENERGY STAR score went from 55 in 2016 to 87 in 2023 (+32 points); its best year on file was 2019, at 89. Site EUI moved from 112.5 kBtu/ft² (2016) to 76.4 kBtu/ft² (2023), a 32% decrease. Reported emissions went from 1,108 tCO₂e to 715 tCO₂e over the same span (down 36%).
What does an ENERGY STAR score of 87 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 87 means the building performs better than about 87% of its national peers. BuildingCensus bands the score into report-card grades; 87 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. Grace St.'s 76.4 kBtu/ft² across 125,820 sq ft works out to about 9.6 billion Btu (2,817 MWh-equivalent) in 2023. Its source EUI of 113.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 690,061 kWh of electricity and 72,559 therms of natural gas for the year.
Which law requires Grace St. to report its energy use?
Grace St. 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 2023 disclosure (source record chicago:252252:2023).
