Its ENERGY STAR score went from 60 in 2019 to 75 in 2024 (+15 points); its best year on file was 2021, at 89. Site EUI moved from 32.5 kBtu/ft² (2019) to 25.9 kBtu/ft² (2024), a 20% decrease.

What does an ENERGY STAR score of 75 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 75 means the building performs better than about 75% of its national peers. BuildingCensus bands the score into report-card grades; 75 falls in band B — above median (70–84). 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. The Villas At Monarch Beach's 25.9 kBtu/ft² across 250,000 sq ft works out to about 6.5 billion Btu (1,898 MWh-equivalent) in 2024. The disclosure also reports 785,224 kWh of electricity and 40,207 therms of natural gas for the year.
