Edith Green-Wendell Wyatt Building "Fins" Taking Shape
The General Service Administration’s Edith Green-Wendell Wyatt Federal building in Portland is getting "fins." Sort of. The unique "fins" and reeds are going up on the west façade of the building currently undergoing a major renovation including tons of green and sustainable features. The reed and "fin" design provides shading for the building. There will be seven "fins" across the west façade of the building each covered with 30 panels of reeds for a total of 1,730 reeds (a total of 52,445 linear feet). Each façade of the building will have unique shading systems tuned for its orientation to the sun. The west façade is covered with the reeds on the fins. The south and east facades will have smaller reeds mounted vertically that also provide shading. The north façade does not have any shading as it is not needed. The reeds provide an average of 50% shading on the west façade to reduce solar heat gain on the building minimizing the energy needed for cooling. A model of the reeds was tested in the light lab to determine the reed profile and frequency needed to achieve the required shading. The reeds, made of extruded aluminum, will be installed through November. The 35-year-old Edith Green-Wendell Wyatt building is undergoing a major modernization project to be completed in 2013.
