Window shapes in the Social Sciences and Humanities Building (top photo) reveal their functions: vertical for public spaces like libraries, square for faculty offices and narrow horizontal bands offering privacy for restrooms. Windows in AOB4 (below left) and Shields Library (below right) tell stories about life on campus. Windows have practical functions. They let people see out (unless you are looking out Briggs Hall's angled ones) and let the light come in. But for architects, windows are an opportunity to sculpt, says Campus Architect Robert Strand. They offer texture and scale, light and shadow. Perhaps the most obvious building sculpture at UC Davis, Strand points out, is the sunscreen. To offset our hot Mediterranean summers, architects have had a heyday designing ways to keep the heat out, ranging from the heavy concrete structures found on Olson and Briggs halls to the deep insets found in the Life Sciences Addition or the Art Building. You can find gems throughout campus-in the original float-glass, double-hung windows on North and South Halls, the north wall of light in the old Mission Revival-style boiler plant near the Music Building or Sproul Hall's "seismic solution" with its tower of glass offices.
