The Napa Valley College Performing Arts Center is comprised of a fully functional performance stage with a 500 seat auditorium, a small black box theater, performance rehearsal and individual practice spaces, music instruction rooms, a costume and scene shop, dressing rooms and shower facilities and support staff office spaces. The building design uses energy efficient systems and lighting wherever possible, passive systems including natural daylighting in office and perimeter spaces as well as natural ventilation within the corridors and lobby are also employed.

Radiant heating and cooling were used where possible to improve occupant thermal comfort, reduce energy consumption, and reduce air system size. Radiant ceiling panels are used in the office spaces and rehearsal rooms to provide occupant comfort. One common air-handling unit (AHU) will condition and provide the required ventilation air for the radiant ceiling spaces with 100% OSA. Radiant floors will be provided in the Main Lobby area. We utilize displacement ventilation systems in high occupancy areas to also provide optimal occupant thermal comfort and reduce the conditioning load on the AHU's. Three diffusion technologies will be used in the displacement systems, including standard perforated duct, Ductsox® and floor diffusers integrated into the main House seating area over a large concrete pressurized plenum. All AHU's will use a variable-frequency drive to increase efficiency.
