Located in Boston’s Back Bay neighborhood, the 157 Berkely Street Liberty Mutual Tower is one of two major building complexes that comprise the Liberty Mutual Home Office campus. The 22-story, 757,000 SF tower was completed in 2013 and is structurally connected to the adjacent 330 Stuart Building, integrating the 130,000 SF historic building with the new construction. From initial occupancy to the present, CMTA has helped this LEED Gold certified building consistently decrease its energy use and operating costs through continuous commissioning, making Liberty Mutual Tower one of Boston’s highest-performing commercial office buildings.
From 2014 to 2022, the owner reduced the total annual energy consumption by an impressive 60.7%, bringing the EUI down from 89 to 35 and saving the owner $4.5 million in utility costs. This impressive achievement is a result of the owner’s ongoing efforts and strategic approach to energy reduction and building system optimization.
