The latest disclosures cover 392 non-refrigerated warehouse buildings in Los Angeles, out of 11,498 buildings citywide. 2309 E 15TH ST's ENERGY STAR score of 93 compares with an average of 68 across the 352 that report a score; it scores higher than 79% of them and lower than 19%. Its site EUI of 2.8 kBtu/ft² is about 86% below the average of 19.5 kBtu/ft² — it uses less energy per square foot than the typical building in that group.

At 21,000 sq ft, it is about 64% below the average floor area of 57,664 sq ft for those buildings. It was built in 1955, 17 years earlier than the group's average year built (1972). Across all 24 jurisdictions BuildingCensus covers, the 4,723 non-refrigerated warehouse buildings average an ENERGY STAR score of 66 and a site EUI of 26.0 kBtu/ft².

How has 2309 E 15TH ST's energy performance changed over time?

BuildingCensus holds 8 Los Angeles disclosures for 2309 E 15TH ST, covering report years 2018–2025. Its ENERGY STAR score went from 4 in 2018 to 93 in 2025 (+89 points); its best year on file was 2022, at 100. Site EUI moved from 25.7 kBtu/ft² (2018) to 2.8 kBtu/ft² (2025), a 89% decrease. Reported emissions went from 36 tCO₂e to 3 tCO₂e over the same span (down 90%).

What does an ENERGY STAR score of 93 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 93 means the building performs better than about 93% of its national peers. BuildingCensus bands the score into report-card grades; 93 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. 2309 E 15TH ST's 2.8 kBtu/ft² across 21,000 sq ft works out to about 0.1 billion Btu (17 MWh-equivalent) in 2025. Its source EUI of 8.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 72 thousand gallons of water for the year.

Which law requires 2309 E 15TH ST to report its energy use?

2309 E 15TH ST 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. The record shown here is the report-year 2025 disclosure (source record la:491672830442:2025). EBEWE requires annual benchmarking plus audits/retro-commissioning every five years for privately owned buildings of 20,000 sq ft or more; non-compliance carries a $202 fee (LAMC §91.9712) plus possible late fees.
