A complete renovation design was provided for the nine-story building, Edward Zorinsky Federal Building in Omaha, Nebraska, USA. The renovation included the replacement of the building facade and heating/cooling, plumbing, lighting and electrical systems. The project contemplated reuse and revitalization of the structure, replacement of windows with energy-efficient windows, installation of sun-shelves and sun-shade devices at exterior windows.
Design and energy-saving features of the building include a three-story atrium and a four-foot-wide daylight corridor around the perimeter of the operating levels. These areas allow the building’s workers ample access to natural sunlight. In addition, exterior lighting shelves reflect light into the building’s core at the ceiling level, while exterior light louvers control excess light and glare from entering the building.
