Smithsonian Institution

Washington, DC and New York City

Supporting the Nation’s Preeminent Museums and Galleries

Mueller Associates has been privileged to work on many renovation projects for the Smithsonian Institution, the world’s largest museum and research complex. Our work spans several decades, more than two dozen venues throughout the Washington metropolitan area, and more than 100 projects.

In recent years we have completed award-winning upgrades at the National Museum of Natural History and the National Postal Museum, both landmark historic buildings in Washington, D.C. Currently, we are engineering the modernization of the popular National Air and Space Museum, a renovation that will significantly improve energy efficiency and environmental controls for this iconic Modernist structure. Our work at the National Zoological Park has included multiple upgrades to facilities such as the Great Ape House, Giant Panda Habitat, American Bison Yard, Great Cats Exhibit, and visitor center. We recently engineered the award-winning Conservation Pavilion and are now providing MEP engineering for the renovation of the historic Bird House.
