How has 251 S OLIVE ST's energy performance changed over time?

BuildingCensus holds 10 Los Angeles disclosures for 251 S OLIVE ST, covering report years 2016–2025. Its ENERGY STAR score went from 3 in 2016 to 88 in 2025 (+85 points).

What does an ENERGY STAR score of 88 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 88 means the building performs better than about 88% of its national peers. BuildingCensus bands the score into report-card grades; 88 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. 251 S OLIVE ST's 57.9 kBtu/ft² across 540,028 sq ft works out to about 31.3 billion Btu (9,164 MWh-equivalent) in 2025. Its source EUI of 110.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 24,686 thousand gallons of water for the year.

Which law requires 251 S OLIVE ST to report its energy use?

251 S OLIVE 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:485753841576:2025). 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.
