Hyatt Regency Hotel Atrium Renovation San Francisco, California The renovation of the landmark Hyatt Regency Hotel Atrium in San Francisco occurred during a brief 4 month period in the spring and summer of 1993. For the first time vertical surfaces, stepped ceilings and pedestrian paths are illuminated to reveal the unique architecture of this 1971 Portman hotel. The central sculpture and fountain, trees and task areas were relit. A grazing techniques which loosely simulates the effect of sunlight rakes the walls. A low voltage open conductor wire system illuminates the cafe and bar, as well as dramatically uplights the horizontally stepped ceiling that rises seventeen floors, 170', above the atrium floor.
