How has The Langham Huntington Pasadena's energy performance changed over time?
BuildingCensus holds 3 California disclosures for The Langham Huntington Pasadena, covering report years 2022–2024. Its ENERGY STAR score went from 68 in 2022 to 76 in 2024 (+8 points).

What does an ENERGY STAR score of 76 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 76 means the building performs better than about 76% of its national peers. BuildingCensus bands the score into report-card grades; 76 falls in band B — above median (70–84). 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. The Langham Huntington Pasadena's 76.0 kBtu/ft² across 549,198 sq ft works out to about 41.7 billion Btu (12,233 MWh-equivalent) in 2024. The disclosure also reports 4,794,834 kWh of electricity and 244,539 therms of natural gas for the year.
