How has Alta Vista Villas's energy performance changed over time?
BuildingCensus holds 2 California disclosures for Alta Vista Villas, covering report years 2023–2024. Its ENERGY STAR score went from 92 in 2023 to 99 in 2024 (+7 points). Site EUI moved from 22.9 kBtu/ft² (2023) to 21.6 kBtu/ft² (2024), a 6% decrease. Reported emissions went from 107 tCO₂e to 95 tCO₂e over the same span (down 12%).
What does an ENERGY STAR score of 99 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 99 means the building performs better than about 99% of its national peers. BuildingCensus bands the score into report-card grades; 99 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. Alta Vista Villas's 21.6 kBtu/ft² across 74,876 sq ft works out to about 1.6 billion Btu (474 MWh-equivalent) in 2024. The disclosure also reports 203,188 kWh of electricity and 9,181 therms of natural gas for the year.
Which law requires Alta Vista Villas to report its energy use?
