DPR Construction – one of the country’s leading general contractors – needed to upgrade the ground floor of a two-story office building for its Newport Beach, California location. The 17,000-square-foot floor plan provided a working canvas for DPR’s open office, embracing lighting as a critical element of the design.
Due to a number of factors about their leased office space, complete natural lighting was not an option. They company decided to use a balance of dimmable direct and indirect LED lighting.
The Substance and Style Lighting Solution
The goal was to provide lighting that was aesthetically and acoustically pleasing for the open ceilings. DPR Construction selected 93 Lithonia Lighting® VT Series LED 2’x 2’ fixtures with Sensor Switch® nLight® controls for their main office space and conference rooms. Gotham® ALED EVO LED downlights were installed throughout hallways, bathrooms, stadium seating BIM lab and showers. To promote out-of-the-box thinking, brainstorming, and collaboration, they developed an Innovation Room, which includes Mark Architectural Lighting™ Slot 2 fixtures to add to the ambiance of the unique, non-traditional space.
Occupancy sensors from Sensor Switch are placed every six to eight workstations and daylighting sensors around the glazed perimeter of the open office automatically dim the intensity of the LED fixtures based on light levels from outside.
One Step Further
As a part of its conservation strategy and initiatives to improve the comfort of its staff, DPR Construction took lighting functionality to the next level. “Through the nLight Virtual WallPod application, every user has dimming capabilities at his or her desk through an iPhone or the task bar of a computer. This application allows users to control fixtures individually, so instead of turning up 10 fixtures for someone to look at a drawing, they only turn up one” said Jason King of DPR Construction.
Looking back on the final lighting design, based on California’s Title-24 2005 calculations, DPR Construction’s space is averaging 0.56 watts per square foot, or a mere 35,600 kilowatt-hours on an annual basis. This is over a 40 percent reduction in lighting power density compared to Title-24 baseline requirements. Furthermore, because DPR Construction was able to capitalize on LED dimming, initial energy consumption data from the Building Dashboard shows an annual projection of only 16,500 kilowatt-hours, under half the consumption predicted in design.
