Frequently asked questions
What is the most energy-efficient large building in Montgomery County?
The Astrid (As147) tops the list with an ENERGY STAR score of 100 among Montgomery County buildings over 50,000 sq ft in the latest Benchmarking Law (Bill 2-14) / BEPS (Bill 16-21) 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.
