451 S HARVARD BLVD

How does 451 S HARVARD BLVD compare with other multifamily housing buildings in Los Angeles?

The latest disclosures cover 3,538 multifamily housing buildings in Los Angeles, out of 11,498 buildings citywide. 451 S HARVARD BLVD's ENERGY STAR score of 82 compares with an average of 78 across the 3,344 that report a score; it scores higher than 44% of them and lower than 53%. Its site EUI of 36.5 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 125,928 sq ft, it is about twice the average floor area of 60,540 sq ft for those buildings. Its 1972 construction date is close to 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 451 S HARVARD BLVD's energy performance changed over time?

BuildingCensus holds 10 Los Angeles disclosures for 451 S HARVARD BLVD, covering report years 2016–2025. Its ENERGY STAR score was 82 in both 2016 and 2025. Site EUI moved from 40.9 kBtu/ft² (2016) to 36.5 kBtu/ft² (2025), a 11% decrease. Reported emissions went from 304 tCO₂e to 253 tCO₂e over the same span (down 17%).

What does an ENERGY STAR score of 82 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 82 means the building performs better than about 82% of its national peers. BuildingCensus bands the score into report-card grades; 82 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. 451 S HARVARD BLVD's 36.5 kBtu/ft² across 125,928 sq ft works out to about 4.6 billion Btu (1,347 MWh-equivalent) in 2025. Its source EUI of 69.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 8,220 thousand gallons of water for the year.

Which law requires 451 S HARVARD BLVD to report its energy use?

451 S HARVARD BLVD 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:469414846471:2025). 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.
