How has 709 S MARIPOSA AVE's energy performance changed over time?

BuildingCensus holds 8 Los Angeles disclosures for 709 S MARIPOSA AVE, covering report years 2018–2025. Its ENERGY STAR score was 98 in both 2024 and 2025.

What does an ENERGY STAR score of 98 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 98 means the building performs better than about 98% of its national peers. BuildingCensus bands the score into report-card grades; 98 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. 709 S MARIPOSA AVE's 30.4 kBtu/ft² across 26,370 sq ft works out to about 0.8 billion Btu (235 MWh-equivalent) in 2025. Its source EUI of 49.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,021 thousand gallons of water for the year.

Which law requires 709 S MARIPOSA AVE to report its energy use?

709 S MARIPOSA 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:471141844144:2025). 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.
