OFFICE Office BUILDINGS OF-OP2.0 Open Office: occupancy sensing Control Needs Automatically turn pendant lights on and off based on occupancy Manual control of wallwash luminaires with automatic off based on occupancy Occupancy-based control of mechanical system Emergency lighting controlled with general lighting; automatic on during power outage Occupancy-based control of workstation plug loads Solution Ultrasonic occupancy sensors and power packs (UT series, BD series) Low Voltage Switch and power pack (BD series) Isolated relay in occupancy sensor Emergency Lighting Control Unit (ELCU) to switch loads based on occupancy when normal power is available Isolé power strip with personal sensor Application Description Space use: Office activities including general administration, clerical, filing, copy areas, financial, engineering, sales Dimensions: Based on 30’ bays, irregular shape; approx. 16,500 sq. ft. Ceiling height: 10’ Cubicle dimensions:8’ x 8’ x 5’ Windows: View windows along south facade with horizontal blinds provided Lighting Pendant mounted indirect/direct luminaires using two T8 lamps and two-lamp 277-volt electronic, program start ballasts. Compact fluorescent wallwashers highlighting the north and south interior walls, using 42-watt triple tube lamps and 277-volt electronic ballasts. Open Open Office Lighting Plan LEGEND Design Solution Description Pendant lighting is automatically turned on and off using the UT-300 series ultrasonic occupancy sensors. The sensors are spaced on a 20’ x 16’ grid to control individual zones, and to assure adequate coverage with partitions. Wallwashers are manually turned on using the L1S single button low voltage switch connected to a BD-100M power pack. While the area is occupied, the occupancy sensor will hold the lighting on. After the area is vacated and after the sensor’s time delay expires, the sensor will turn the wallwashers off. Integration between the lighting and mechanical system is achieved by connecting the sensor’s isolated relay directly with the HVAC system to provide occupancy-based ON/OFF control of HVAC. Power packs are DIN-rail mounted in an enclosure in an accessible location. Emergency lighting is controlled with general lighting; in the event of ordinary power loss, the ELCU will force emergency lighting on.
