Its emissions intensity of 3.9 kgCO₂e/ft² is about 86% above the group average of 2.1 kgCO₂e/ft².

At 88,517 sq ft, it is about 41% below the average floor area of 150,919 sq ft for those buildings. Its 1988 construction date is close to the group's average year built (1988). 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 Las Casas Ii's energy performance changed over time?

BuildingCensus holds 2 California disclosures for Las Casas Ii, covering report years 2023–2024. Its ENERGY STAR score was 93 in both 2023 and 2024. Site EUI moved from 39.1 kBtu/ft² (2023) to 41.1 kBtu/ft² (2024), an 5% increase. Reported emissions went from 336 tCO₂e to 346 tCO₂e over the same span (up 3%).

What does an ENERGY STAR score of 93 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 93 means the building performs better than about 93% of its national peers. BuildingCensus bands the score into report-card grades; 93 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 California, 65% 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. Las Casas Ii's 41.1 kBtu/ft² across 88,517 sq ft works out to about 3.6 billion Btu (1,066 MWh-equivalent) in 2024. The disclosure also reports 827,929 kWh of electricity and 10,114 therms of natural gas for the year.

Which law requires Las Casas Ii to report its energy use?

Las Casas Ii reports under AB 802 (Public Resources Code §25402.10), the legal basis of California's Building Energy Benchmarking Program (statewide), which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2024 disclosure (source record california:36039439:2024). AB 802 requires every California commercial building over 50,000 sq ft to report energy use to the CEC annually; the CEC publicly discloses the results statewide.
