The final circuiting and channel numbers shall be defined in the design documentation and record drawings to ensure the metering tags are correct and accurately setup on the Satec System and the BMS.
C. Lighting: 1. Target LPD of 0.5W/SF or less. This can be achieved in most cases through efficient lighting design, use of low wattage fixtures and lamps and reflective surfaces as well as LED task lights.
2. Specify 100% LED lamps.
3. Implement lighting controls, including daylight dimming controls for all daylit areas and vacancy/occupancy sensors for all connected lighting load. Daylight-responsive controls shall be provided to control lighting within 15 feet of windows and under skylights. 4. Vacancy sensor controls shall be installed to control lights in enclosed offices, training rooms, conference/meeting/multipurpose rooms, copy/print rooms, lounges, employee lunch and break rooms, storage rooms, closets, other spaces enclosed by floor-to-ceiling height partitions. As per code the lights in the rooms shall be switched on by switch and go off after 15 min of no occupancy
5. Occupancy sensor (dual technology) controls shall be installed to control lights in open plan office areas and restrooms and to turn lights off after 15 minutes.
6. Provide a BACnet license for all new lighting control panels and any existing lighting control panels which have this capability and provide a connection to the BMS to communicate the status of the occupancy sensors and to allow a remote on/off cycling of the lights to refresh the lighting control panels in the event of ‘freezing’ . Co-ordinate with the HVAC layouts to ensure both lighting and HVAC zones align. Document occupancy sensor zone names on floor plans to allow automatic energy saving in the HVAC system using lighting system data. 7. Consider optimizing daylight and views for occupants, which may be achieved through a design that includes interior rather than perimeter offices or perimeter offices with glass fronts if perimeter offices are a design requirement. 8. Lighting calculations to demonstrate alignment with circadian rhythm and electric lights maintain illuminance equivalent melanopic lux of 150-300 at workstations (measured on the vertical plane facing forward four feet above the finished floor to simulate the view of the occupant). 9. Consider furniture partitions to be 42” or lower in height in order to allow for access to daylight and views. Additional privacy may be achieved through clear partition glass installed above the furniture panels. 10. Design and build to offer occupants control of lighting. Consider providing task lights with dimmers or at least three light levels (on/off/mid) at all workstations. Consider providing multi- zone controls in multi-occupant spaces (such as conference rooms) with at least three lighting levels or scenes.
11. Use light sources with a CRI of 90 or higher.
12. Consider providing manual or automatic glare control devices (shades or blinds) in all regularly occupied spaces.
