School_HolyAngelsSchoolAnnex's ENERGY STAR score of 96 compares with an average of 45 across the 365 that report a score; it scores higher than 97% of them and lower than 2%. Its site EUI of 36.6 kBtu/ft² is about half of the average of 72.7 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 2.5 kgCO₂e/ft² is about 60% below the group average of 6.2 kgCO₂e/ft².

At 105,351 sq ft, it is about 14% below the average floor area of 121,824 sq ft for those buildings. It was built in 1950, 7 years later than the group's average year built (1943).

What does an ENERGY STAR score of 96 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 96 means the building performs better than about 96% of its national peers. BuildingCensus bands the score into report-card grades; 96 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. School_HolyAngelsSchoolAnnex's 36.6 kBtu/ft² across 105,351 sq ft works out to about 3.9 billion Btu (1,130 MWh-equivalent) in 2023. Its source EUI of 50.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 208,386 kWh of electricity and 31,421 therms of natural gas for the year.

Which law requires School_HolyAngelsSchoolAnnex to report its energy use?

School_HolyAngelsSchoolAnnex 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:166547:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
