Frequently asked questions

What is the most energy-efficient large building in Seattle?

SWEDISH MEDICAL CENTER FIRST HILL - Campus tops the list with an ENERGY STAR score of 100 among Seattle buildings over 50,000 sq ft in the latest Seattle Energy Benchmarking Ordinance (SMC 22.920) disclosure.

Why only large buildings?

Restricting the ranking to buildings over 50,000 sq ft keeps it meaningful — perfect scores are common among small buildings, while running a high score at scale is the real efficiency achievement.
