How has ZIBA Headquarters's energy performance changed over time?
BuildingCensus holds 2 Portland disclosures for ZIBA Headquarters, covering report years 2023–2024. Its ENERGY STAR score went from 76 in 2023 to 86 in 2024 (+10 points).

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. ZIBA Headquarters's 28.8 kBtu/ft² across 71,867 sq ft works out to about 2.1 billion Btu (607 MWh-equivalent) in 2024. The disclosure also reports 593,788 kWh of electricity and 454 therms of natural gas for the year.
