Lansing, Mich. — The Christman Company announced that it has been awarded LEED Platinum certification by the U.S. Green Building Council (USGBC) for The Christman Building, its recently rehabilitated national headquarters located in downtown Lansing, Mich. The building was formally certified with certifications in two categories, Commercial Interiors and Core and Shell. This is the world’s first building project to achieve this “double Platinum” distinction.

Listed on the National Register of Historic Places, the building is an example of sustainable green historic building practices. The many green features of the project include water use reduction, optimized energy performance, construction waste management, a focus on daylighting and a healthy indoor environment.

The 1928-built former Mutual Building was recently rededicated as The Christman Building following a major historic rehabilitation which preserved its many historic features — including Pewabic tiled stairways and exterior limestone detailing — while upgrading its interior to a Class A office building. The building is headquarters to Christman as well as long-term tenants Kelley Cawthorne and Michigan Municipal League.

Design services provided by SmithGroup for the building’s historic rehabilitation, included architectural design; mechanical, electrical and structural engineering; lighting and interior design; historic preservation design; LEED certification services; and State Historic Tax Application services.
