One Del Mar's ENERGY STAR score of 94 compares with an average of 75 across the 4,912 that report a score; it scores higher than 75% of them and lower than 22%. Its site EUI of 31.5 kBtu/ft² is about 44% 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 1.7 kgCO₂e/ft² is about half of the group average of 3.6 kgCO₂e/ft².
At 122,551 sq ft, it is about 19% below the average floor area of 151,937 sq ft for those buildings. It was built in 2001, 16 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 One Del Mar's energy performance changed over time?
BuildingCensus holds 7 California disclosures for One Del Mar, covering report years 2018–2024. Its ENERGY STAR score went from 95 in 2018 to 94 in 2024 (-1 points); its best year on file was 2020, at 99. Site EUI moved from 33.7 kBtu/ft² (2018) to 31.5 kBtu/ft² (2024), a 7% decrease. Reported emissions went from 291 tCO₂e to 208 tCO₂e over the same span (down 29%).
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. One Del Mar's 31.5 kBtu/ft² across 122,551 sq ft works out to about 3.9 billion Btu (1,131 MWh-equivalent) in 2024. The disclosure also reports 830,826 kWh of electricity for the year.
Which law requires One Del Mar to report its energy use?
One Del Mar 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:6838465:2024).
