UC Riverside School of Medicine Research Building Wins IES Lighting Control Innovation Award Of Merit

The Lighting Control Innovation Award was created in 2011 as part of the Illuminating Engineering Society’s Illumination Awards program, which recognizes professionalism, ingenuity and originality in lighting design. LCA is proud to sponsor the Lighting Control Innovation Award, which recognizes projects that exemplify the effective use of lighting controls in nonresidential applications. In this award’s second year, 13 projects were recognized with an Award of Merit.

This month, we will explore the role that digital addressable lighting controls play at the University of California Riverside School of Medicine Research Building. Lighting design by Nino De La Rosa, LC, LEED-AP, Lighting Designer, Pivotal Lighting Design / Affiliated Engineers, Inc. Control manufacturers/products: Lutron Electronics’ Quantum Digital Addressable Lighting and shade control system, Wattstopper occupancy sensors.

The UC Riverside School of Medicine 60,000-sq.ft. Biomedical Sciences building utilizes innovative daylighting strategies to optimize natural light and energy efficiency while preserving views. A complete digital addressable lighting control system was used to reduce lighting energy consumption while providing maximum controllability by the users of laboratories, support spaces, conference rooms and open offices.

Working closely with the user group, the design team established a uniform 20-footcandle maintained ambient light level for occupied lab spaces.

Interior light shelves allow for deeper daylight penetration into laboratory spaces while preserving daylight views. Integrated motorized shades in the clerestory section above 9 ft. eliminate unwanted glare.

Integrated motorized shades deploy from the sill upwards, and a sophisticated control system using rooftop and interior photosensors coupled with a rooftop weather station responds dynamically to actual sky conditions. The daylighting system is integrated with the electric lighting, thereby ensuring a uniform level of ambient light regardless of time of day or changing exterior conditions.

LED task lighting with integral occupancy sensors increases task illuminance to 100 footcandles.

Task tuning was utilized building wide. Initial illuminance within lab support spaces is 80% of the available illuminance. Higher illuminance levels are achieved by pressing and holding wall switches to increase
light levels.

The lighting in all circulation areas is controlled by occupancy sensors.

Public area lighting is programmed to reduce illuminance to minimum levels when occupancy is not detected.

Multiscene lighting controllers provide lighting scenes with integral shade control within conference rooms.

Wall-mounted occupancy sensors and fixture-integral light level controllers are utilized in perimeter office spaces.

The building is on track to receive LEED Gold certification, exceeding the client’s expectations and UC Riverside’s initial criteria for LEED Silver. This project was designed within budget and exceeds California’s Title 24 building energy code by 25%.
