Frequently asked questions

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

null tops the list with an ENERGY STAR score of 100 among Boston buildings over 50,000 sq ft in the latest BERDO 2.0 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.
