Its site EUI of 2.4 kBtu/ft² is about 88% below the average of 19.8 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 0.1 kgCO₂e/ft² is about 89% below the group average of 1.3 kgCO₂e/ft².
At 125,700 sq ft, it is about half of the average floor area of 238,298 sq ft for those buildings. It was built in 1986, 8 years earlier than the group's average year built (1994). Across all 24 jurisdictions BuildingCensus covers, the 4,082 distribution center buildings average an ENERGY STAR score of 65 and a site EUI of 24.2 kBtu/ft².
How has Wiegman Distribution Center 2's energy performance changed over time?
BuildingCensus holds 7 California disclosures for Wiegman Distribution Center 2, covering report years 2018–2024. Its ENERGY STAR score went from 100 in 2021 to 99 in 2024 (-1 points); its best year on file was 2021, at 100. Site EUI moved from 1.5 kBtu/ft² (2021) to 2.4 kBtu/ft² (2024), an 60% increase. Reported emissions went from 12 tCO₂e to 17 tCO₂e over the same span (up 49%).
What does an ENERGY STAR score of 99 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 99 means the building performs better than about 99% of its national peers. BuildingCensus bands the score into report-card grades; 99 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 California, 65% 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. Wiegman Distribution Center 2's 2.4 kBtu/ft² across 125,700 sq ft works out to about 0.3 billion Btu (88 MWh-equivalent) in 2024. The disclosure also reports 88,110 kWh of electricity for the year.
Which law requires Wiegman Distribution Center 2 to report its energy use?
