The latest disclosures cover 10 wholesale club/supercenter buildings in Chicago, out of 3,852 buildings citywide. LZ Products's ENERGY STAR score of 92 compares with an average of 60 across the 9 that report a score; it scores higher than 78% of them and lower than 11%. Its site EUI of 22.8 kBtu/ft² is about 70% below the average of 76.8 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 2.3 kgCO₂e/ft² is about 71% below the group average of 8.0 kgCO₂e/ft².
At 72,000 sq ft, it is about 43% below the average floor area of 126,360 sq ft for those buildings. It was built in 1900, 91 years earlier than the group's average year built (1991). Across all 24 jurisdictions BuildingCensus covers, the 482 wholesale club/supercenter buildings average an ENERGY STAR score of 71 and a site EUI of 79.1 kBtu/ft².
How has LZ Products's energy performance changed over time?
BuildingCensus holds 3 Chicago disclosures for LZ Products, covering report years 2015–2017. Its ENERGY STAR score was 92 in both 2015 and 2017. Site EUI moved from 23.0 kBtu/ft² (2015) to 22.8 kBtu/ft² (2017), a 1% decrease. Reported emissions went from 177 tCO₂e to 163 tCO₂e over the same span (down 8%).
What does an ENERGY STAR score of 92 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 92 means the building performs better than about 92% of its national peers. BuildingCensus bands the score into report-card grades; 92 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. LZ Products's 22.8 kBtu/ft² across 72,000 sq ft works out to about 1.6 billion Btu (481 MWh-equivalent) in 2017. Its source EUI of 40.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 168,879 kWh of electricity and 10,628 therms of natural gas for the year.
Which law requires LZ Products to report its energy use?
LZ Products 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 2017 disclosure (source record chicago:137157:2017). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
