What does an ENERGY STAR score of 51 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 51 means the building performs better than about 51% of its national peers. BuildingCensus bands the score into report-card grades; 51 falls in band D — lowest band (1–54). It sits 24 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. 1055 W Granville's 111.2 kBtu/ft² across 80,600 sq ft works out to about 9 billion Btu (2,627 MWh-equivalent) in 2023. Its source EUI of 154.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 506,920 kWh of electricity and 72,357 therms of natural gas for the year.

Which law requires 1055 W Granville to report its energy use?

1055 W Granville 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:173868:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
