What do Cambridge's most efficient buildings have in common?

21 of them post a perfect 100. By property type the list is led by multifamily housing (68), office (14) and K-12 school (5). Their average site EUI is 43.9 kBtu/ft², about 63% below the citywide average of 117.2 kBtu/ft². Combined they cover 16.9 million square feet; the median ranked building has 109,285 sq ft.

The ranking covers buildings of 50,000 sq ft or more that report an ENERGY STAR score, ordered by score and then by floor area. Cambridge's 2023 BEUDO amendments require non-residential buildings of 100,000+ sq ft to reach net-zero emissions by 2035 (reductions starting 2026) and those of 25,000–100,000 sq ft by 2050 (starting 2030).

Frequently asked questions

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

130 Cambridge Park Dr, tops the list with an ENERGY STAR score of 100 among Cambridge buildings over 50,000 sq ft in the latest BEUDO 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.
