The latest disclosures cover 387 office buildings in Chicago, out of 3,852 buildings citywide. 1700-GGP Headquarters's ENERGY STAR score of 97 compares with an average of 69 across the 320 that report a score; it scores higher than 98% of them and lower than 2%. Its site EUI of 51.8 kBtu/ft² is about 26% below the average of 70.4 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 6.7 kgCO₂e/ft² is about 11% below the group average of 7.5 kgCO₂e/ft².
At 221,383 sq ft, it is about half of the average floor area of 488,124 sq ft for those buildings. It was built in 1998, 42 years later than the group's average year built (1957). Across all 24 jurisdictions BuildingCensus covers, the 15,264 office buildings average an ENERGY STAR score of 73 and a site EUI of 59.3 kBtu/ft².
How has 1700-GGP Headquarters's energy performance changed over time?
BuildingCensus holds 2 Chicago disclosures for 1700-GGP Headquarters, covering report years 2015–2016. Its ENERGY STAR score went from 96 in 2015 to 97 in 2016 (+1 points). Site EUI moved from 56.6 kBtu/ft² (2015) to 51.8 kBtu/ft² (2016), a 8% decrease. Reported emissions went from 1,657 tCO₂e to 1,484 tCO₂e over the same span (down 10%).
What does an ENERGY STAR score of 97 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 97 means the building performs better than about 97% of its national peers. BuildingCensus bands the score into report-card grades; 97 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. 1700-GGP Headquarters's 51.8 kBtu/ft² across 221,383 sq ft works out to about 11.5 billion Btu (3,361 MWh-equivalent) in 2016. Its source EUI of 117.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,952,445 kWh of electricity and 48,145 therms of natural gas for the year.
Which law requires 1700-GGP Headquarters to report its energy use?
1700-GGP Headquarters 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:160229:2016). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
