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.
This month, we explore a detailed lighting control solution installed at Brookhaven Service Center in Brookhaven, NY. Lighting control design by CEG Solutions LLC. Photography by Samuel Ross. Lighting controls by Acuity Brands.
Complexity: Brookhaven Service Center is a 500,000 square foot call center on Long Island with 3,000 employees who work in 24/6 staggered shifts. The existing lighting system required all fixtures in the large open areas to be On, even during periods of low occupancy.
Concept: 3,425 fixtures were upgraded to LED retrofit kits with integrated network controls. Each fixture was individually programmed and grouped into a zone of four to six surrounding fixtures, allowing for individual control of smaller groups of fixtures: (1) dim zone to 20% after 15 minutes of no detected occupancy, (2) turn zone off after an additional 15 minutes of no detected occupancy, and (3) program emergency fixtures to remain at 80% of maximum lumen output.
Integration: The solution was developed with flexibility in mind. Building operators can manually adjust light levels on a per-fixture basis to accommodate specific tasks, and wall switches allow building occupants to temporarily override fixture operations. Because the solution involved programming of each individual fixture controls, the zones can be easily adjusted based on future space utilization requirements.
Performance Criteria: Prior to installation, a mockup was performed in a small area of the facility to ensure that the final solution achieved expected savings and satisfied space functionality requirements. The controls solution has now been installed for over six months with no reported issues.
Energy Impact: This lighting solution reduces total building annual electricity consumption by 3.5MM kWh, or 25%. Savings have been measured and verified post-installation. In addition, more efficient fixtures were installed than originally specified, which further increased total realized savings.
Discretionary Bonus: The final solution created a visually pleasing “spotlight” effect for occupants walking through the building during periods of low occupancy.
