The prototype is designed for a south exposure on the ground floor. The horizontal louvers are bent slightly to accommodate a random, or a specifically designed, pattern. The louvers themselves are translucent which will minimize their visual impact, but will still block direct sunlight passing through the glass. These lovers would be made of polycarbonate or other plastic material to increase durability. Additionally, the louvers can be replaced independently by releasing the clips on either side. The louvers are attached every 5 feet to a vertical rod by a cast stainless steel clamp which is then tied into the foundation below and the steel frame above. The stainless steel rod is held back against the wall by way of "yoke" pieces every 6 feet vertical.
The curtain wall structure is provided by vertical beam pieces made from milled stainless steel with circles cut out. These circles are spaced every 8" and are interspersed with slotted attachment points for the yoke. The connections are all made using slots or set-screws which can be adjusted in the field for a perfect fit. The unit is designed to be adjusted; vertically by way of the yoke’s position on the vertical rod, as well as the position of the louver clamps; horizontally (front/back) by way of the slotted connection to the frame; and horizontally (side-to-side) by the yoke’s position on the cross piece. Additionally, the louvers are pinned by a single point on either end so they can be pushed front to back.
The mullion is integrated with the frame to provide support and is constructed of aluminum and stainless steel components. The glass, which is insulated, has a horizontal frit pattern on the outside gradually becoming denser as it nears the bottom.
This project won a second place award in the SARUP Student Design Competition in 2009.
