The Missouri Historical Society purchased the historic, former United Hebrew Temple for retrofit into an archival library and curatorial office/storage/research center. Mechanical system design with strict environmental requirements was necessary to properly house and maintain artifacts. The project was designed for energy efficient preservation of rare books, tapes, photos and other artifacts. Project features include:

• Design of HVAC system to allow space temperatures to be maintained at 65 degrees Fahrenheit, 50 percent relative humidity year round
• Installation of an ice harvesting system to limit demand loads and to provide a proper medium to generate low temperature air
• Clean steam humidification system to minimize carcinogen exposure
• Central systems eliminate water piping in collection areas
• Building automation system (BAS) for control and monitoring of mechanical systems
• Addressable fire alarm system with central computer and tie to off-site central monitoring station
• New security system including motion sensors, glass breakage sensors, door monitors, keypads, card readers, video cameras and a central console
