There is a dearth of case studies relative to Control Room lighting, however, Control Rooms are important work environments which must ensure the safety of critical processes. As an indicator of their importance to organizations, Control Rooms have been referred to as the “brains” or “nerve centers” of facilities. Generally, lighting has been found to influence work performance, alertness and safety within a very wide range of facility types. The Illuminating Engineering Society (IES) makes recommendations for light levels for various types of applications, including Control Rooms. Researchers conducted in situ case studies in two Control Rooms of different vintages at the same facility in an effort to determine how well one transportation and storage company’s older and newer Control Rooms’ lighting levels met current recommendations. An Extech LT300 light meter was used to empirically measure horizontal footcandles (lux) on task surfaces and AutoCAD software was employed to document existing conditions and associated light levels. The findings revealed empirically that the older Control Room illuminated with “static” lighting did not meet industry standards for light levels while the newer Control Room illuminated with “dynamic” lighting met the industry standards and also allowed for user adjustments now and in the future.
