Its site EUI of 32.0 kBtu/ft² is about 43% below the average of 56.4 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 2.1 kgCO₂e/ft² is about 42% below the group average of 3.6 kgCO₂e/ft².
At 75,292 sq ft, it is about half of the average floor area of 151,937 sq ft for those buildings. It was built in 2019, 34 years later than the group's average year built (1985). 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 Carlsbad E2's energy performance changed over time?
BuildingCensus holds 3 California disclosures for Carlsbad E2, covering report years 2021, 2022, 2024. Its ENERGY STAR score was 94 in both 2021 and 2024. Site EUI moved from 35.1 kBtu/ft² (2021) to 32.0 kBtu/ft² (2024), a 9% decrease. Reported emissions went from 126 tCO₂e to 157 tCO₂e over the same span (up 25%).
What does an ENERGY STAR score of 94 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 94 means the building performs better than about 94% of its national peers. BuildingCensus bands the score into report-card grades; 94 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. Carlsbad E2's 32.0 kBtu/ft² across 75,292 sq ft works out to about 2.4 billion Btu (706 MWh-equivalent) in 2024. The disclosure also reports 387,303 kWh of electricity and 13,115 therms of natural gas for the year.
Which law requires Carlsbad E2 to report its energy use?
