The latest disclosures cover 3,538 multifamily housing buildings in Los Angeles, out of 11,498 buildings citywide. 1150 S WESTMORELAND AVE's ENERGY STAR score of 75 compares with an average of 78 across the 3,344 that report a score; it scores higher than 34% of them and lower than 65%. Its site EUI of 35.6 kBtu/ft² is roughly in line with the average of 37.2 kBtu/ft² — it uses less energy per square foot than the typical building in that group.
At 31,648 sq ft, it is about half of the average floor area of 60,540 sq ft for those buildings. It was built in 1987, 12 years later than the group's average year built (1975). Across all 24 jurisdictions BuildingCensus covers, the 59,945 multifamily housing buildings average an ENERGY STAR score of 70 and a site EUI of 59.0 kBtu/ft².
How has 1150 S WESTMORELAND AVE's energy performance changed over time?
BuildingCensus holds 8 Los Angeles disclosures for 1150 S WESTMORELAND AVE, covering report years 2018–2025. Its ENERGY STAR score went from 100 in 2018 to 75 in 2025 (-25 points); its best year on file was 2018, at 100. Site EUI moved from 3.6 kBtu/ft² (2018) to 35.6 kBtu/ft² (2025), an 889% increase. Reported emissions went from 7 tCO₂e to 62 tCO₂e over the same span (up 745%).
What does an ENERGY STAR score of 75 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 75 means the building performs better than about 75% of its national peers. BuildingCensus bands the score into report-card grades; 75 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 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. 1150 S WESTMORELAND AVE's 35.6 kBtu/ft² across 31,648 sq ft works out to about 1.1 billion Btu (330 MWh-equivalent) in 2025. Its source EUI of 62.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,454 thousand gallons of water for the year.
Which law requires 1150 S WESTMORELAND AVE to report its energy use?
1150 S WESTMORELAND AVE reports under LA Municipal Code Div. 97, §91.9701 (EBEWE), the legal basis of Los Angeles's Existing Buildings Energy & Water Efficiency (EBEWE) program, which publishes each covered building's annual benchmarking results.
