How has 18100 Von Karman's energy performance changed over time?
BuildingCensus holds 7 California disclosures for 18100 Von Karman, covering report years 2018–2024. Its ENERGY STAR score went from 90 in 2018 to 95 in 2024 (+5 points).

What does an ENERGY STAR score of 95 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 95 means the building performs better than about 95% of its national peers. BuildingCensus bands the score into report-card grades; 95 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. 18100 Von Karman's 34.5 kBtu/ft² across 244,718 sq ft works out to about 8.4 billion Btu (2,474 MWh-equivalent) in 2024. The disclosure also reports 1,478,194 kWh of electricity and 35,158 therms of natural gas for the year.
