    To safeguard its archive of more than five million artifacts, the Church of Jesus Christ of Latter-day Saints commissioned the new 230,000 SF Church History Library. Sophisticated lighting/daylighting strategies were used throughout the building to conserve energy, to preserve treasured artifacts, and to satisfy the wide age range of facility users. For artifact preservation, all building lighting systems were designed with UV filtering, and lighting levels were kept to a minimum to limit artifact degradation. Occupancy sensor controls limit exposure time of materials to the deteriorating effects of the visible light spectrum. To promote energy efficiency, a relay-based control system allows for lighting to be automatically turned off in perimeter areas when sufficient daylight is present. Low-ballast-factor ballasts in combination with Super T8 lamps were used to maximize energy conservation and to reduce operating costs. The Church History Library’s lighting power density is 0.84 watts/SF which is well below ASHRAE energy standards and helped the building achieve LEED-NC Silver certification. To provide an open, welcoming atmosphere for visitors and staff, custom fluorescent pendant lights were designed for the main lobby entrance. Each of the individual custom fluorescent pendant lights are controlled separately via a networked relay control system to harvest daylight. Special care was taken in the selection of decorative lighting pendants in the reception area to accentuate the building’s sophisticated interiors while avoiding glare to building occupants. For the Church History Library’s exterior, building-integrated ceramic metal halide uplights accentuate the building façade. LED lighting was specified for the exterior garden trellises, entry lobby millwork, and outer reading room reception area millwork to reduce energy usage and to minimize maintenance.
