How has Vali-Hai Apartments's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Vali-Hai Apartments, covering report years 2015–2025. Its ENERGY STAR score went from 5 in 2015 to 31 in 2025 (+26 points); its best year on file was 2023, at 68. Site EUI moved from 98.2 kBtu/ft² (2015) to 105.6 kBtu/ft² (2025), an 8% increase. Reported emissions went from 134 tCO₂e to 218 tCO₂e over the same span (up 63%).
What does an ENERGY STAR score of 31 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 31 means the building performs better than about 31% of its national peers. BuildingCensus bands the score into report-card grades; 31 falls in band D — lowest band (1–54). It sits 44 points below 75, the threshold for ENERGY STAR certification. In Seattle, 69% 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. Vali-Hai Apartments's 105.6 kBtu/ft² across 43,346 sq ft works out to about 4.6 billion Btu (1,341 MWh-equivalent) in 2025. Its source EUI of 165.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 395,068 kWh of electricity and 32,280 therms of natural gas for the year.
Which law requires Vali-Hai Apartments to report its energy use?
