All high efficiency window systems have a shading coefficient of 0.29 and a solar heat gain coefficient (SHGC) of 0.25. An important part of the building’s envelope is a highly reflective roofing system. The flat roof membrane, which covers 24% of the roof area, consists of four layers. The top is a tough, high-UV blocking white acrylic, which keeps the roof surface cool; the second and the bottom layers are high quality asphalt, which provides waterproofing; and the third layer is a fiberglass mat, which provides a solid, dimensionally stable substrate for the other roofing membrane components. The nonflat portion of the roof is composed of tile with a steel frame. The roof has an overall R-value of 39.2 and a solar reflectance of 49%. The exterior walls are brick, cast stone and clay tile. The brick and cast stone are part of a cavity wall system, composed of structural steel studs with glass mat gypsum sheathing and a self-adhering sheet air barrier that form the structural wall to which the brick and cast stone are attached. The brick is supported by shelf angles at each slab level and the cast stone bears on the foundations spring 2012 State-of-the art technology, such as the video wall in the open court, permeates the building, promoting and supporting both individual and team-oriented discussion, research, and interaction. wherever it covers the full height of the wall.
