11651 HART ST

How does 11651 HART ST compare with other non-refrigerated warehouse buildings in Los Angeles?

The latest disclosures cover 392 non-refrigerated warehouse buildings in Los Angeles, out of 11,498 buildings citywide. 11651 HART 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 3.1 kBtu/ft² is about 84% below the average of 19.5 kBtu/ft² — it uses less energy per square foot than the typical building in that group.

At 110,684 sq ft, it is about twice the average floor area of 57,664 sq ft for those buildings. Its 1973 construction date is close to 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 11651 HART ST's energy performance changed over time?

BuildingCensus holds 10 Los Angeles disclosures for 11651 HART ST, covering report years 2016–2025. Its ENERGY STAR score went from 99 in 2016 to 93 in 2025 (-6 points); its best year on file was 2017, at 100. Site EUI moved from 2.1 kBtu/ft² (2016) to 3.1 kBtu/ft² (2025), an 48% increase. Reported emissions went from 17 tCO₂e to 19 tCO₂e over the same span (up 12%).

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. 11651 HART ST's 3.1 kBtu/ft² across 110,684 sq ft works out to about 0.3 billion Btu (101 MWh-equivalent) in 2025. Its source EUI of 7.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 76 thousand gallons of water for the year.

Which law requires 11651 HART ST to report its energy use?

11651 HART 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:444885894819:2025). 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.
