How does 170 W 39TH ST compare with other distribution center buildings in Los Angeles?

The latest disclosures cover 172 distribution center buildings in Los Angeles, out of 11,498 buildings citywide. 170 W 39TH ST's ENERGY STAR score of 80 compares with an average of 65 across the 149 that report a score; it scores higher than 62% of them and lower than 35%. Its site EUI of 7.5 kBtu/ft² is about 65% below the average of 21.5 kBtu/ft² — it uses less energy per square foot than the typical building in that group.

At 21,775 sq ft, it is about 75% below the average floor area of 86,482 sq ft for those buildings. It was built in 1970, 7 years earlier than the group's average year built (1977). Across all 24 jurisdictions BuildingCensus covers, the 4,082 distribution center buildings average an ENERGY STAR score of 65 and a site EUI of 24.2 kBtu/ft².

How has 170 W 39TH ST's energy performance changed over time?

BuildingCensus holds 8 Los Angeles disclosures for 170 W 39TH ST, covering report years 2018–2025. Its ENERGY STAR score went from 92 in 2024 to 80 in 2025 (-12 points); its best year on file was 2024, at 92. Site EUI moved from 19.3 kBtu/ft² (2019) to 7.5 kBtu/ft² (2025), a 61% decrease. Reported emissions went from 28 tCO₂e to 9 tCO₂e over the same span (down 66%).

What does an ENERGY STAR score of 80 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 80 means the building performs better than about 80% of its national peers. BuildingCensus bands the score into report-card grades; 80 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. 170 W 39TH ST's 7.5 kBtu/ft² across 21,775 sq ft works out to about 0.2 billion Btu (48 MWh-equivalent) in 2025. Its source EUI of 20.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 73 thousand gallons of water for the year.

Which law requires 170 W 39TH ST to report its energy use?

170 W 39TH 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:478126826763:2025). 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.
