Edward Zorinsky Federal Building Renovation

Omaha, Nebraska

Complete renovation design was provided for the nine-story building, including replacement of the building facade and heating/cooling, plumbing, lighting and electrical systems. Although not seeking LEED certification, the project followed the principles of the US Green Building Council. Sustainable design features include reuse and revitalization of the structure, replacement of windows with energy-efficient windows, installation of sun-shelves and sun-shade devices at exterior windows, use of recyclable and recycled renovation materials, rooftop rainwater collection as greywater to flush toilets, photo-voltaic rooftop solar collectors, and installation of a highly energy efficient HVAC system.
