The Church of Jesus Christ of Latter-day Saints, Church History Library - Total Building Commissioning (TBC ) is providing building commissioning services including LEED™ (Leadership in Energy and Environmental Design) commissioning at the new five-floor, 250,000 sq. ft. Church History Library. Mechanical systems that are being commissioned include HVAC for library, office, archive, and holding storage areas. The holding storage areas include secure and high-security holding and storage facilities which require high levels of protection from contaminants as well as extremely high levels of temperature and humidity control.

Constant and variable air volume air handlers with desiccant dehumidifiers and heat recovery systems are used to ensure the high levels of temperature and humidity control necessary for a library and archives facility of this caliber. The building houses long-term storage using cryogenic storage capabilities that require very strict temperature (maintaining constant -4 degrees F) and precise humidity control.
Also commissioned are high-level gas fire suppression and early detection fire alarm systems which utilize an air sampling smoke detection system and sprinkled and inert gas suppression systems.
TBC commissioned the following:
• LEED™ commissioning
• Gas fire suppression systems
• Early fire detection systems
• HVAC systems
• Constant and variable air volume air handlers with desiccant dehumidifiers
• Electrical power distribution systems
• Emergency and UPS power systems
• Plumbing systems
