UCSF Gateway Bldg 23B

San Francisco, CA

Geometry means to “measure the earth,” and the science of geometry has always served to rationalize nature. For the ancients, it was the disk of the sun that inspired the circle. In Egypt, the four corners of the rising and setting sun at the summer and winter solstices marked the square mat of flat earth. In the Renaissance, the mechanics and proportions of the human body were translated into mathematical systems. Currently, knowledge of nature has evolved from the scale of the mechanical to the intricacies of the molecular, to subtle and complex mapping that has changed our under-standing of the nature of nature. It is this contemporary conception of order that this gateway parking structure expresses. Translucent channel glass arranged in DNA-derived patterns with open voids encloses the facades and provides ventilation for the parking, also conferring on the building a distinctive and memorable image. The glass has a stippled surface that radiates light, forming a shimmering veil around the concrete structure. At night, the channel glass is illuminated from within. On the south facade are photovoltaic panels arranged in the same patterns. These, along with photovoltaic panels on a trellis on the roof, generate energy for the building. This airy glass box of light is an entry and front door to the campus. The lobby is an eighty-five-foot void containing the elevator core and stairs. The structural system consists of precast columns eighty-five feet high. Sixty-foot beams fit into haunches on the columns. The precast system supports poured-in-place floors. Paul Valéry claimed that it is the skin that is the deepest; this project is about a skin that provides an image protected from the building’s function.
