Prism completed a feasibility study which provided the scope and scheduling for a retrofit project under the BC Hydro PowerSmart Program. Energy efficiency measures included conversion of incandescent and fluorescent lighting, recommissioning of the direct digital control (DDC) system, and conversion of the main air handling system. Ductwork changes were made to the Omnimax air handling system to provide better air movement and distribution, thus improving both energy use and comfort in the theatre. A professional mountain climber was even contracted to replace the exterior dome bulbs with more energy-efficient lighting!
