Its site EUI of 47.0 kBtu/ft² is about 74% below the average of 181.8 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 3.0 kgCO₂e/ft² is about 73% below the group average of 11.1 kgCO₂e/ft².
At 55,703 sq ft, it is about half of the average floor area of 121,485 sq ft for those buildings. It was built in 1988, 4 years earlier than the group's average year built (1992). Across all 24 jurisdictions BuildingCensus covers, the 795 laboratory buildings average an ENERGY STAR score of 29 and a site EUI of 231.7 kBtu/ft².
How has 4 Cromwell's energy performance changed over time?
BuildingCensus holds 7 California disclosures for 4 Cromwell, covering report years 2018–2024. Site EUI moved from 35.3 kBtu/ft² (2021) to 47.0 kBtu/ft² (2024), an 33% increase. Reported emissions went from 105 tCO₂e to 169 tCO₂e over the same span (up 60%).
What does a site EUI of 47.0 kBtu/ft² mean?
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. 4 Cromwell's 47.0 kBtu/ft² across 55,703 sq ft works out to about 2.6 billion Btu (767 MWh-equivalent) in 2024. The disclosure also reports 744,199 kWh of electricity for the year.
Which law requires 4 Cromwell to report its energy use?
