How has 947 N ORANGE DR's energy performance changed over time?

What does an ENERGY STAR score of 100 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: 100 is the top of the scale. BuildingCensus bands the score into report-card grades; 100 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. 947 N ORANGE DR's 4.9 kBtu/ft² across 57,595 sq ft works out to about 0.3 billion Btu (83 MWh-equivalent) in 2025. Its source EUI of 13.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 145 thousand gallons of water for the year.

Which law requires 947 N ORANGE DR to report its energy use?

947 N ORANGE DR 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:457919854854:2025). 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.
