Sadler Center Lighting Upgrade
Centrally located in the heart of campus, the Sadler Center serves as William & Mary’s primary student union and hub for student life and campus activity. The facility supports dining, studying, student organization activities, lectures, film screenings, formal presentations, and large campus events. As the building aged, its original 1994 lighting systems and controls became inefficient, unreliable, and inadequate for modern campus operations.

Project Info Continued ….
The existing pendant and downlight fixtures were still powered by incandescent lamps and no longer provided the performance, efficiency, or flexibility required for today’s dynamic use patterns. The legacy ETC lighting control system had reached the end of its service life, frequently requiring manual workarounds and offering limited programmability. The project was initiated to modernize the lighting and control systems in the multipurpose rooms and Commonwealth Auditorium while enhancing visual quality, operational flexibility, and long-term maintainability.
The lighting design was developed to support a wide range of use cases, from small lectures and study sessions to student events and formal presentations. In each multipurpose room, all incandescent fixtures and ineffective indirect wall-mounted luminaires were removed and replaced with a new multi-layered lighting approach consisting of:
-
Indirect lighting to provide uniform ambient illumination and gently wash the wood ceiling surfaces.
-
Direct lighting to support reading, writing, speaking, and collaborative activities.
-
Track lighting systems to provide adaptable, reconfigurable illumination for changing room layouts.
-
Accent and lectern lighting, including ETC Source Four Mini fixtures, to highlight speakers and presentation areas.
Lighting controls were a central component of the design. The existing control units were replaced with a modern system providing four-button preset scene controls in each.
The system allows simple room-level operation while also providing centralized configuration and programming via laptop for facilities staff. Zoned control was provided around roll-down projector screens to allow selective dimming for presentations while maintaining appropriate illumination in surrounding areas. The system was designed to support future integration with the campus QSC audio-visual infrastructure.
The Commonwealth Auditorium received a parallel upgrade to support larger gatherings and performance events. House lighting, including pendant fixtures, wall-mounted luminaires, and downlights integrated within sound baffles, was replaced with high-efficiency, dimmable LED fixtures. The control system was designed to coordinate both ambient house lighting and stage lighting, including center-stage PAR fixtures, while maintaining DMX communication with the mixing board to support live performances, ceremonies, and special events.
Life safety coordination was incorporated into the design, including provisions for connection to the building fire alarm system where required for code compliance. This ensured appropriate lighting response during emergency conditions while maintaining compatibility with normal operational modes.
The completed lighting and control upgrades provide flexible, energy-efficient, and programmable systems that support the full range of academic, social, and performance activities within the Sadler Center while preparing the facility for future technology integration.
