How has 4540 HAZELTINE AVE's energy performance changed over time?
BuildingCensus holds 8 Los Angeles disclosures for 4540 HAZELTINE AVE, covering report years 2018–2025. Its ENERGY STAR score went from 74 in 2018 to 95 in 2025 (+21 points); its best year on file was 2021, at 95. Site EUI moved from 39.4 kBtu/ft² (2018) to 33.4 kBtu/ft² (2025), a 15% decrease. Reported emissions went from 56 tCO₂e to 43 tCO₂e over the same span (down 23%).
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 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. 4540 HAZELTINE AVE's 33.4 kBtu/ft² across 23,606 sq ft works out to about 0.8 billion Btu (231 MWh-equivalent) in 2025. Its source EUI of 59.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,171 thousand gallons of water for the year.
