How has Hotel Zachary's energy performance changed over time?
BuildingCensus holds 6 Chicago disclosures for Hotel Zachary, covering report years 2018–2023. Its ENERGY STAR score went from 3 in 2019 to 4 in 2023 (+1 points); its best year on file was 2021, at 10. Site EUI moved from 179.5 kBtu/ft² (2019) to 157.4 kBtu/ft² (2023), a 12% decrease. Reported emissions went from 3,612 tCO₂e to 2,937 tCO₂e over the same span (down 19%).
What does an ENERGY STAR score of 4 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 4 means the building performs better than about 4% of its national peers. BuildingCensus bands the score into report-card grades; 4 falls in band D — lowest band (1–54). It sits 71 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. Hotel Zachary's 157.4 kBtu/ft² across 184,703 sq ft works out to about 29.1 billion Btu (8,520 MWh-equivalent) in 2023. Its source EUI of 317.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 4,702,236 kWh of electricity and 130,342 therms of natural gas for the year.
Which law requires Hotel Zachary to report its energy use?
Hotel Zachary 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:255949:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
