Its ENERGY STAR score went from 2 in 2016 to 21 in 2025 (+19 points); its best year on file was 2021, at 99. Site EUI moved from 53.4 kBtu/ft² (2016) to 61.1 kBtu/ft² (2025), an 14% increase. Reported emissions went from 383 tCO₂e to 318 tCO₂e over the same span (down 17%).

What does an ENERGY STAR score of 21 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 21 means the building performs better than about 21% of its national peers. BuildingCensus bands the score into report-card grades; 21 falls in band D — lowest band (1–54). It sits 54 points below 75, the threshold for ENERGY STAR certification. 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. 512 ROSE AVE's 61.1 kBtu/ft² across 93,840 sq ft works out to about 5.7 billion Btu (1,680 MWh-equivalent) in 2025. Its source EUI of 125.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 5 thousand gallons of water for the year.

Which law requires 512 ROSE AVE to report its energy use?

512 ROSE AVE 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:418283821910:2025). 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.
