At 594,104 sq ft, it is about 881% above the average floor area of 60,540 sq ft for those buildings. It was built in 2010, 35 years later than 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 1 W CENTURY DR's energy performance changed over time?

BuildingCensus holds 10 Los Angeles disclosures for 1 W CENTURY DR, covering report years 2016–2025. Its ENERGY STAR score went from 2 in 2016 to 33 in 2025 (+31 points). Site EUI moved from 53.5 kBtu/ft² (2016) to 43.7 kBtu/ft² (2025), a 18% decrease. Reported emissions went from 1,841 tCO₂e to 1,442 tCO₂e over the same span (down 22%).

What does an ENERGY STAR score of 33 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 33 means the building performs better than about 33% of its national peers. BuildingCensus bands the score into report-card grades; 33 falls in band D — lowest band (1–54). It sits 42 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. 1 W CENTURY DR's 43.7 kBtu/ft² across 594,104 sq ft works out to about 26 billion Btu (7,609 MWh-equivalent) in 2025. Its source EUI of 91.7 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 9,532 thousand gallons of water for the year.

Which law requires 1 W CENTURY DR to report its energy use?

1 W CENTURY 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:436131843133:2025). 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.
