How has Pacific Building's energy performance changed over time?
BuildingCensus holds 2 Portland disclosures for Pacific Building, covering report years 2023–2024. Its ENERGY STAR score went from 89 in 2023 to 86 in 2024 (-3 points); its best year on file was 2023, at 89. Site EUI moved from 50.8 kBtu/ft² (2023) to 50.3 kBtu/ft² (2024), a 1% decrease. Reported emissions went from 1,104 tCO₂e to 1,021 tCO₂e over the same span (down 8%).
What does an ENERGY STAR score of 86 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 86 means the building performs better than about 86% of its national peers. BuildingCensus bands the score into report-card grades; 86 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 Portland, 66% 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. Pacific Building's 50.3 kBtu/ft² across 181,453 sq ft works out to about 9.1 billion Btu (2,675 MWh-equivalent) in 2024. The disclosure also reports 1,504,737 kWh of electricity and 39,856 therms of natural gas for the year.
Which law requires Pacific Building to report its energy use?
