How has 11450 CALVERT ST's energy performance changed over time?
BuildingCensus holds 8 Los Angeles disclosures for 11450 CALVERT ST, covering report years 2018–2025. Its ENERGY STAR score went from 98 in 2019 to 100 in 2025 (+2 points); its best year on file was 2024, at 100. Site EUI moved from 19.0 kBtu/ft² (2018) to 34.7 kBtu/ft² (2025), an 83% increase. Reported emissions went from 24 tCO₂e to 43 tCO₂e over the same span (up 81%).
What does an ENERGY STAR score of 100 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: 100 is the top of the scale. BuildingCensus bands the score into report-card grades; 100 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 Los Angeles, 63% 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. 11450 CALVERT ST's 34.7 kBtu/ft² across 22,494 sq ft works out to about 0.8 billion Btu (229 MWh-equivalent) in 2025. Its source EUI of 61.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 994 thousand gallons of water for the year.
