There is no Building Automation System (BAS). 5 LIGHTING SYSTEMS The building lighting types are listed in Table 4. There is no overall building lighting control system for automatically shutting down lights based on time of day or other controls. There are occupancy sensors only in the shower rooms as well as some cycle timers. There are limited areas with large windows, except the service bay which provide an opportunity for daylight harvesting there. There are several areas under lit due to fixture with poor or no optics. Many areas do not take advantage of ceiling reflectance to increase the light levels. Also dull and non-reflective finishes reduce the lighting effectiveness. The existing parabolic fixtures are less optically efficient than other fixtures. Figures 12 and 13 shows some of the elements of the lighting system located in the SRE building.
