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 application of lighting controls in nonresidential spaces.
This month, we will explore the role that an innovative lighting control solution plays at the Cleveland Clinic’s Fairview Hospital Intensive Care Unit.

Holistic patient care was the design criteria at Cleveland Clinic Fairview ICU. Through automatic lighting controls and patient centered design considerations, patient satisfaction, employee efficiency and energy savings were improved.
One aspect of the holistic design was to select luminaires that accentuated the linear and nonintrusive architectural details of the space while providing non-obtrusive illumination to corridors, work areas and patient rooms. Another aspect was the innovative lighting controls employed with the corridor lighting to mimic the day/night light cycle utilizing an astronomical time clock and automatic dimming controls. Lighting levels begin at 3 fc at dawn …
Night …
Dusk …
Mid morning …
Noon: slowly increase to 35 fc at noon, and finally dim back down to 3 fc at dusk and through the night to repeat again the next day. This cycle helps to maintain the patient’s circadian rhythm which improves recovery time. Nurses’ stations are equipped with override controls to bring the corridors to full brightness in the event of an emergency. The performance of the system has provided patients and staff an improved experience. The dimming of the corridors occurs seamlessly. Patients and nurses are oblivious to it occurring.

Patients typically only have control of the ambient fixture above their bed. Design at Fairview allows for control of all luminaires in the room from the patient bed. This control is made possible using low voltage relays and switching. Non-critical nurse calls are reduced by the increased control the patients have over their environment. The project was within budget and certified LEED/NC v2.2. Return on investment is expected through energy savings and improved efficiencies. The added benefit of efficiency provides an energy cost savings of over 40% and lamp life is calculated to be increased by over 30%.
