building

Completed in 1990, 343 Sansome occupies a full block in San Francisco's Financial District, combining a new 16-story building with an existing, historically significant building and offering 232,000 square feet of net rentable office space. At the lobby level, 343 Sansome includes approximately 13,000 square feet of retail space, which is open on three sides to the surrounding neighborhood and a sculpture court. A landscaped rooftop garden is open to the public during business hours, providing a significant amenity to tenants and visitors.

The new construction's sensitivity to its adjoining building reflects the care with which the project was conceived. John Burgee Architects, with Philip Johnson as design consultant, designed 343 Sansome in accordance with San Francisco's Downtown Plan, which emphasizes "meeting the housing, open space, and transportation needs created by downtown development, and preserving significant older buildings and their settings." As a result, the building's scale and design are sympathetic to the character of the other buildings in the Financial District, and 343 Sansome further avoids casting new shadows on public park spaces in the area.

The building owner and management have exercised similar attentiveness in managing the energy use at the site. By retrofitting select building systems, 343 Sansome Street earned the ENERGY STAR for superior energy performance. Climate control systems include high-efficiency chillers and variable frequency drives (VFDs) on all of the building's air handling units, which allow the volume of air moved in the building to vary depending upon demand. Other areas of significant energy savings include the use of high-efficiency T-8 fluorescent bulbs, and the installation of a Windows-based building energy management system incorporating Direct Digital Control (DDC). This system enables centralized, real-time monitoring of building systems, zone by zone, and gives management the ability to monitor and maintain building conditions at optimal levels, improving tenant comfort while simultaneously improving energy efficiency.

343 Sansome's exterior design is sensitive to its impact on its neighborhood, and its interior energy use is managed to reduce environmental impact--making the building a model of progressive, sustainable thinking.
