601 Congress Street is the corporate headquarters for a leading global services group. The LEED® certified mid rise office building is located on a redevelopment brownfield site in South Boston.

SOM began the building performance rating process early in the design with the intent of reducing first cost for green initiatives. The building is in the 95th percentile, or the top 5%, of performance based on predicted annual energy costs and metrics found using the EPA Energy Star target finder.

The design for the exterior skin of the building utilizes a double-skin façade which facilitates dynamic flow of air to enhance the curtain wall’s energy performance. The six-story glass atrium provides workers with an interior landscaped space, increases daylight into interior occupied floor areas and provides added energy benefits. Additional sustainable strategies include drip irrigation for landscaping, sensors on faucets to achieve significant water conservation and a landscaped green roof adjacent to the outdoor terrace on the 12th floor.
