1 LIGHTING CONTROLS PART 1: GENERAL 1.01 SUMMARY COMMENTS A. CU has developed this lighting control guideline to direct design professionals toward standard solutions that meet the University s performance requirements. This document defines typical space functions (i.e. laboratory) and provides lighting control solutions based on the room architecture, desired technology, cost, and performance. B. This document is intended to be used as a reference for design professionals working for CU; and as such should not be used as a technical specification. C. All Lighting Control System (LCS) projects shall meet the energy and control requirements outlined in the most current edition of the Energy Conservation Construction Code of New York State. For LEED projects, comply with the requirements of Credit EQc6.1: Controllability of Systems Lighting and coordinate the design of lighting controls as required for Credit EAp2 Minimum Energy Performance and EAc1 Optimize Energy Performance. D. This document does not define products for replacement or preventative maintenance, and should only be used for renovation and new construction projects. E. Any proposed deviations from this standard shall be submitted in writing to CU Facilities Engineering and Energy & Sustainability departments for approval RELATED SECTIONS A.

B. The design professional shall coordinate with the Commissioning Agent to ensure that the contract documents include the scope of work associated with commissioning efforts. C. Refer to the IES DG document for additional information GENERAL SYSTEM GUIDELINES A. Interior spaces enclosed by walls or floor-to-ceiling partitions will have at least one accessible lighting control to manually control lighting within the space. Controls may be toggle switches, low-voltage switches, dimming controls, or multi-scene controls. B. Interior spaces that are normally occupied shall allow the occupant to reduce the connected lighting load by at least 50%. Lighting reduction may be achieved by any of the following: dual switching of alternate rows of luminaires, alternate luminaires, or alternate lamps; switching the middle luminaire lamps independently of the outer lamps; switching each luminaire or lamp; luminaire dimming. C. Interior spaces that are required to have manual control will also include automatic controls to automatically turn off the lights when the space is not occupied via a sensor or time based schedule. 1. Vacancy sensors shall be used for all interior, occupied spaces, unless otherwise directed. 2. In lecture spaces, specify occupancy sensors for the first 5 rows of seating only. 3. Ceiling-mounted sensors shall be used for spaces over 100-square feet in area. Sensors will utilize Passive Infrared (PIR); dual-technology sensors are not permitted. 4. Wall-mounted sensors shall be used for spaces under 100-square feet in area. Sensors will utilize Passive Infrared (PIR); dual-technology sensors are not permitted. 5. Ceiling-mounted ultrasonic sensors shall be used for ganged toilet rooms with partitions. DATE: 11/16/17 DATE: 11/16/17 Page 5 of 11

6 6. Sensors shall be placed to provide the most effective coverage area and prevent nuisance operation. 7. Occupancy sensors shall be used in public spaces, corridors, hallways, and stairs to adjust light levels automatically based on occupancy. 8. Multi-scene control systems (i.e., Crestron controlled for a lecture or auditorium space) shall be configured to automatically turn off the lights when the space is not occupied, and interface with the BACS via dry contacts for occupied/unoccupied sensor status to enable HVAC temperature setback and airflow control strategies and lights on/lights off status. 9. Do not use sensors in rooms containing electrical distribution equipment (switchboards, switchgear, motor control centers, and panelboards), mechanical rooms, or in spaces where the sudden loss of illumination may pose a life safety hazard. D. Interior spaces that are normally occupied and with sufficient natural light shall include daylighting and dimming controls. E. Exterior luminaires shall be controlled by photocells, astronomic controls, or the BACS. F. Luminaires used for emergency egress shall not be connected to the LCS BACS INTERFACE A. The requirements in this Section apply to an LCS that integrates with the Building Automation and Control System. B. Integrated and Networked LCS s shall use the BACS interface as the primary method to perform all system programming, control, and monitoring. C. Auxiliary relays shall be used in all occupied spaces to interface the lighting control system to the BACS for occupied/unoccupied HVAC temperature setback and airflow control strategies. D. The BACS interface shall display graphic zones for each lighting zone with the location of all equipment. E. The BACS interface shall include floor plans, and display the status of all luminaires, including room occupancy, lights on/off, and a foot-candle level for dimmed spaces.
