Cleveland’s 32-story Celebrezze Federal Building will get a new exterior wall [http://www.chicagotribune.com/news/local/ct-met-kamin-stimulus-0201-20110131,0,2393681.story] of aluminum and glass that will boost the 1960s-era structure’s energy efficiency. A gap of air will be left between the old stainless steel and glass walls and the new walls. The new outer skin will increase the insulation of the building, and is projected to reduce annual energy costs by 17 percent.
The $121 million project will be funded by federal stimulus money. The double wall design will filter out harsh sunlight and create an insulating layer of air that moderates temperatures. Office buildings in Europe have used double walls for more than a decade, but the technology remains unusual in the US.
Interactive Design Eight Architects [http://www.idea8.com/site/] designed the project that will yield an updated look, making the building’s appearance appear to change with light conditions.
