How does Glenwood Apartments compare with other multifamily housing buildings in Chicago?

The latest disclosures cover 1,515 multifamily housing buildings in Chicago, out of 3,852 buildings citywide. Glenwood Apartments's ENERGY STAR score of 95 compares with an average of 62 across the 1,472 that report a score; it scores higher than 88% of them and lower than 10%. Its site EUI of 61.7 kBtu/ft² is about 14% below the average of 72.0 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 4.8 kgCO₂e/ft² is about 17% below the group average of 5.8 kgCO₂e/ft².

At 54,770 sq ft, it is about 73% below the average floor area of 206,097 sq ft for those buildings. It was built in 1917, 54 years earlier than the group's average year built (1971). Across all 24 jurisdictions BuildingCensus covers, the 59,945 multifamily housing buildings average an ENERGY STAR score of 70 and a site EUI of 59.0 kBtu/ft².

What does an ENERGY STAR score of 95 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 95 means the building performs better than about 95% of its national peers. BuildingCensus bands the score into report-card grades; 95 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. Glenwood Apartments's 61.7 kBtu/ft² across 54,770 sq ft works out to about 3.4 billion Btu (990 MWh-equivalent) in 2016. Its source EUI of 88.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 181,179 kWh of electricity and 27,612 therms of natural gas for the year.

Which law requires Glenwood Apartments to report its energy use?

Glenwood Apartments 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 2016 disclosure (source record chicago:102644:2016). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
