The Church of Jesus Christ Latter Day Saints - North Phoenix Temple

The new temple is approximately 58,000 square feet including four floor levels with an additional small sub-basement. The high end level of finishes and one of a kind detail in the architecture required significant coordination between all disciplines during the design and construction process. In order to accommodate the reduced available space required for the building systems, a variable refrigerant flow (VRF) system was implemented for the mechanical design. The use of VRF allowed for the ceiling space, vertical shafts and exterior penetrations throughout the building to be minimized, and it also allowed for smaller zones with critical temperature control as occupancy loads vary throughout the spaces in the building. The VRF system was given an additional efficiency boost by tempering the ventilation air using a dedicated outside air unit. Plumbing systems include domestic hot and cold water, sanitary sewer, roof drainage, natural gas, font system including circulation, heating and chemical treatment, and a fire sprinkler system.

The building electrical systems include lighting, power, life safety, telephone/data, security and CCTV, special audio/visual systems, and a standby emergency generator for life safety and owner-specific requirements. Lighting systems include multiple level automated general illumination systems, specialty, accent, task, decorative, exterior and landscape. Special lighting control was provided to allow for the dimming and control of architectural and accent lighting. Upon completion of installation, LSW assisted with the site lighting aiming and commissioning to achieve the desired architectural lighting effects.
