How has Astor House's energy performance changed over time?
BuildingCensus holds 9 Chicago disclosures for Astor House, covering report years 2015–2023. Its ENERGY STAR score went from 35 in 2015 to 34 in 2023 (-1 points); its best year on file was 2021, at 39. Site EUI moved from 119.8 kBtu/ft² (2015) to 91.4 kBtu/ft² (2023), a 24% decrease. Reported emissions went from 2,266 tCO₂e to 1,409 tCO₂e over the same span (down 38%).
What does an ENERGY STAR score of 34 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 34 means the building performs better than about 34% of its national peers. BuildingCensus bands the score into report-card grades; 34 falls in band D — lowest band (1–54). It sits 41 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. Astor House's 91.4 kBtu/ft² across 206,150 sq ft works out to about 18.8 billion Btu (5,522 MWh-equivalent) in 2023. Its source EUI of 139.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,483,490 kWh of electricity and 137,881 therms of natural gas for the year.
Which law requires Astor House to report its energy use?
Astor House 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:158644:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
