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 will explore an innovative installation of lighting and controls as part of an office renovation at Bristol-Myers Squibb in Lawrenceville, NJ. Lighting and control design by HDR.

Health is the heart of the pharmaceutical industry. Corporate health for this client indicated a need for renovation to accommodate additional employee workstations and improve energy efficiency. The design team viewed this 275,730 square foot office renovation as a way to also improve the health of employees who’ve dedicated their careers to improving the health of others.
The existing buildings are built into a sloping terrain, presenting a unique challenge for maximizing natural light to workplaces where entire floors and large portions of floors are located below grade with no access to daylight. Tunable white LED fixtures back-light frosted glass placed in the same curtain wall system used elsewhere, and mimic the natural circadian color shift of light through a 24-hour cycle. This strategy allowed 25,000 square feet without access to daylight, previously used for storage and support, to be reclaimed for open office workstations. Success of this design was best illustrated by observing an employee walk toward this glass wall while talking on his phone saying, “Can you hear me now?”
Design began February 2016 and construction was complete September 2018; 5 months ahead of schedule at a cost of $15/sq ft. This project has a LPD 32% below ASHRAE 90.1- 2015, and was awarded LEED Silver. Additionally, high-end trim settings assured target illumination levels were achieved day one without the need to
over-illuminate to accommodate LED lumen depreciation. High end trim adjustments reduced the connected LPD from 0.56 watts/square foot to 0.44 watts/square foot. The new distributed relay control system utilizes a central time clock to control the circadian wall, daylight harvesting in all areas with natural light, and occupancy or vacancy sensors controlling every light, further reducing energy consumption. Furthermore, the distributed relay approach allows for easy expansion to other portions of the campus via network connection.
Prior to renovation, perimeter enclosed offices blocked access to daylight. Switched fluorescent parabolic troffers and high partitions isolated workers and decreased lighting efficiency.
Linear LED slot lights perpendicular to exterior windows direct your eye to captivating views. Daylight harvesting conserves energy by dimming and turning off electric lighting.
High end trim settings were programmed for each driver to ensure uniform delivery of 40fc and capture the energy needed to accommodate lamp lumen depreciation.
Employees arrive and depart to a warm 2700K, shifting to a 5500K peak between 11am and 1pm. Extended fades subtly blend changes without alerting occupants.
Documents provided detailed riser diagrams for lighting and shade controls, as well as a sequence of operation for each relay.
