This multi-use building contains offices for the California Secretary of State as well as facilities for the State Archives and Golden State Museum. The Offices of the Secretary of State include the Legislative Bill Annex, a 100-seat multimedia auditorium, cafeteria and banquet facilities, and a childcare facility. The Archives includes the 32,000 square foot Golden State Museum, a main research room, document processing and storage, and laboratories. The exhibit, research, and document areas are served by environmental control systems designed for preservation of documents and artifacts. The Golden State Museum brings California’s rich history to life with a mix of traditional exhibits and state-of-the-art technology. Multimedia exhibits tell the stories of California’s people, places, promises and politics. Like the Archive space, the exhibit areas are served by environmental control systems designed for preservation of documents and artifacts. The museum was the first of the new generation of exhibit environments that feature "immersion experiences," which integrates the visitor with the exhibitry. This provided a challenge to provide cooling and ventilation to awkward spaces, which required careful design of such parts as slot diffusers that are concealed within the exhibits.
