How has Ambassador: Ambassador's energy performance changed over time?
BuildingCensus holds 3 California disclosures for Ambassador: Ambassador, covering report years 2019, 2020, 2024. Its ENERGY STAR score went from 88 in 2019 to 86 in 2024 (-2 points); its best year on file was 2020, at 92. Site EUI moved from 53.3 kBtu/ft² (2019) to 56.0 kBtu/ft² (2024), an 5% increase. Reported emissions went from 236 tCO₂e to 245 tCO₂e over the same span (up 3%).
What does an ENERGY STAR score of 86 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 86 means the building performs better than about 86% of its national peers. BuildingCensus bands the score into report-card grades; 86 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. Ambassador: Ambassador's 56.0 kBtu/ft² across 76,609 sq ft works out to about 4.3 billion Btu (1,257 MWh-equivalent) in 2024. The disclosure also reports 370,266 kWh of electricity and 30,258 therms of natural gas for the year.
