The Old Capitol is a national historic landmark located on the heart of the University of Iowa's campus. During the renovations efforts of the Old Capitol, Gessner Group took extreme care in assuring that all mechanical, plumbing, electrical and fire protections systems were concealed so as to preserve the 19th century interior period décor. Ductwork and slot diffusers are completely concealed within the architectural design elements. Electrical receptacles are obscured within wooden baseboards, accessible via a removable panel. The Old Capitol basement historical archive utilizes a dry-agent fire suppression system. Thus, in the event of a fire, fire and water damage to the documents will be minimal. Specialty lighting designs were also implemented. Chandeliers and wall sconces are electrified yet match the details of the original candle type. Lighting design concepts also incorporated concealed fixtures to vary lighting levels as required for anticipated space use.
