Typical breezeway cross section, showing interior program spaces to each side, below the flat, turf roofs. Each of these spaces has operable clerestory windows that provide indirect light and fresh air from the breezeways. At night, the windows are opened to take advantage of the large diurnal change in temperatures to flush the building with fresh, cool air. The interior spaces all have raised floors to accommodate supply of conditioned air. Return air is drawn in through steps in the otherwise curved ceilings. The ceiling geometry works with the natural convection currents created by warming air in the spaces. - West Edge Architects, Peter M. Mitsakos & Associates
