San Francisco, California
The GAP Headquarters consists of a 15 story office building totalling 540,000 sq. ft. with two levels of underground parking. The building also offers its employee's a cafeteria, several outdoor decks, and an art gallery and exhibition hall.
Two Folsom Street is an exemplar of environmentally sustainable design. The 540,000 sq. ft building was the first high-rise in San Francisco to utilize operable windows as well as a highly economical low-pressure underfloor air-supply system that takes advantage of the building’s thermal mass to reduce peak cooling loads. Both the atrium and the ten-foot-eight inch ceilings bring natural light deep into the building’s interior.
As a sustainably designed project, all the MEP systems were designed with energy conservation and flexibility in mind. For this project, CB Engineers designed an HVAC system which included a 1,100-ton central plant with multiple chillers and boilers. The building's main air handling system of 500,000cfm consists of six custom air handlers, utilizing a space-saving design, thus minimizing the impact on office space.
As a result, the office space now supports Gap’s mission of providing their employees, with a working environment, that clearly inspires and motivate all employees to excel.
