Located in Hartford's central business district, the Phoenix Companies headquarters makes a dramatic statement on the Hartford skyline with a style, grace and elegance that is as fresh today as when the building opened in 1963. This landmark is the world's first two-sided office building.  Developed, owned and occupied by the Phoenix, the building was a key component in the renewal of Hartford's business district and the creation of the adjacent Constitution Plaza.   The building was designed by the renowned architectural firm of Harrison and Abramovitiz. This firm designed other significant buildings such as the United Nations and the Lincoln Center for the Performing Arts, both in New York.


Generally known in the Hartford area as the "Boat Building", the Phoenix Companies headquarters is a stunning architectural statement located between downtown and the Connecticut River, adjacent to Interstate 91.  The 454,000 gross square foot building has a nearly square, three floor base that houses the largest contiguous workspace in the building as well as below-grade parking for 275 cars.  The base supports the 13 story all glass tower, technically called a lenticular hyperboloid.  The distinctive tower comprises approximately 230,000 square feet of usable space. Heating and cooling utilities are provided to the building by a district heating and cooling plant.

In 2003, a corporate real estate strategy was adopted.  This initiative sought to maximize the utilization of owned assets and included the funding for renovations of One American Row.  In March of 2004, the first phase of the project began. In the workspace areas, the existing lighting system was converted to the higher efficiency GE Ultra Max F28 T-8 technology. In addition, the lighting systems were then wired to control relays, so that the lighting can now be controlled by the energy management system.  The original air distribution system was a high pressure, dual duct design, engineered during a period in time when energy economics were not a prime consideration. This was replaced with a single cold deck, variable volume system, with electronic VAV terminal boxes.  The tower system relies primarily on the exterior convector system for controlling interior climate conditions. The original single loop system was ineffective due to the large southern exposure on one side of the curtain wall. That system was replaced with a split loop system that now allows each side to heat or cool independently of the other. Cooling coils in the large fan systems were replaced and all other central fan system cooling coils were cleaned.

All the original fan motors were replaced with premium efficiency units, and variable speed drives were added to several systems. A carbon monoxide ventilation control system was installed in the garages to minimize fan operating hours. The current TAC building automation system was upgraded, fully commissioned, and all of the HVAC control strategies were revised. Phoenix received over $160,000 in energy efficiency incentives from Connecticut Light and Power's energy conservation program.  In November 2007, the property qualified for the ENERGY STAR Buildings award.
