How has La Jolla Executive Tower's energy performance changed over time?
BuildingCensus holds 7 California disclosures for La Jolla Executive Tower, covering report years 2018–2024. Its ENERGY STAR score went from 90 in 2018 to 92 in 2024 (+2 points); its best year on file was 2023, at 94. Site EUI moved from 50.5 kBtu/ft² (2018) to 40.2 kBtu/ft² (2024), a 20% decrease. Reported emissions went from 876 tCO₂e to 695 tCO₂e over the same span (down 21%).
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 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. La Jolla Executive Tower's 40.2 kBtu/ft² across 268,407 sq ft works out to about 10.8 billion Btu (3,162 MWh-equivalent) in 2024. The disclosure also reports 2,168,919 kWh of electricity for the year.
Which law requires La Jolla Executive Tower to report its energy use?
La Jolla Executive Tower reports under AB 802 (Public Resources Code §25402.10), the legal basis of California's Building Energy Benchmarking Program (statewide), which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2024 disclosure (source record california:1585336:2024).
