In 2019 Princeton University engaged the services of Circadia Group to design and oversee the replacement of Frick Chemistry Laboratory lighting and lighting controls. The project, defined by three stages started in June of 2019 and is anticipated to be completed in early 2020.
Phase 1 consisted of replacing over 1300 linear T5 fluorescent fixtures with new energy-efficient LED fixtures that utilize a specialized trunking system. The fixture trunking system overcame mounting challenges and provided flexibility for locating fixtures directly above the lab workbenches.
The new fixtures are controlled with a wireless, hybrid 0-10v control system allowing for occupancy sensing and scheduling. The controls system was programmed and commissioned by Circadia Group to have a 40% high-end trim. This trim equaled existing foot-candles, will extend the product life, and will achieve unanticipated energy savings shortening the ROI.
Phase 2 scheduled to start in August of 2019 will comprise replacing additional fluorescent lab pendant fixtures with linear direct/indirect LED pendants. These fixture upgrades will also share the same hybrid, wireless control system and be programmed to match.
Phase 3 to start in spring 2021 will include replacing all remaining incandescent and fluorescent fixtures throughout the building with LED technology. This will include the 4 story atrium, corridors, offices, common areas, bathrooms, dining, and conference areas. This existing controls system will be replaced with the same wireless hybrid system installed in the previous two phases and will be merged to form a uniform and intuitive lighting control system.
