200 Clarendon Street, Transforming a Boston Landmark


Delivering the highest standards in environmental performance and customer experience.

200 Clarendon Street is an iconic office building located in Boston’s Back Bay neighborhood. Designed by Henry Cobb and I. M. Pei in the late 1960s, 200 Clarendon Street was completed in 1976 and has stood as New England’s tallest building and one of Boston’s most iconic landmarks for over 40 years. The building offers 1.7m square feet of office space with dramatic views over downtown Boston and the Charles River. Its central location close to public transportation and cultural centers results in a uniquely desirable place to work. Though the minimalist, modernist project was a true architectural achievement and the design had proven ageless, the original mechanical and control systems had long exceeded their useful life and were in need of replacement.

After completing the acquisition in 2010, BXP committed to a multi-year capital improvement and modernization plan to systematically repair or replace all major mechanical and control systems with a goal of reducing energy consumption and maintenance costs while improving overall operational efficiency and occupant comfort. The capital improvement plan for 200 Clarendon Street was developed with a focus on both the immediate building needs and the desire to establish a new operating methodology that would effect permanent reductions in utility (electricity and steam) consumption, greenhouse gas generation, and improve the customer experience. With over $13M in capital improvements completed since 2012, the building has markedly increased its operational efficiency and customer experience – reflected in the Energy Star Label and the LEED-Existing Building Gold certification awarded to the building in 2017 – to a point befitting its stature as a destination of choice for those seeking commercial office space in the Boston market.
