How has Astor Villa Condominium Association's energy performance changed over time?

What does an ENERGY STAR score of 78 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 78 means the building performs better than about 78% of its national peers. BuildingCensus bands the score into report-card grades; 78 falls in band B — above median (70–84). 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. Astor Villa Condominium Association's 40.6 kBtu/ft² across 111,150 sq ft works out to about 4.5 billion Btu (1,323 MWh-equivalent) in 2023. Its source EUI of 103.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,128,824 kWh of electricity and 6,643 therms of natural gas for the year.

Which law requires Astor Villa Condominium Association to report its energy use?

Astor Villa Condominium Association 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:254151:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
