2 As can be seen here, the intent of this credit is to allow occupants to control their lighting at their individual workstations and in common areas. 35

3 For NC: Provide individual lighting controls for 90% (minimum) of the building occupants to enable adjustments to suit individual task needs and preferences Provide lighting system controls for all shared multi occupant spaces to enable adjustments that meet group needs and preferences. For Schools, there are two cases to consider: CASE 1. in Administrative Offices and Other Regularly Occupied Spaces, the project must Provide individual lighting controls for at least 90% of the building occupants to enable adjustments to suit individual task needs and preferences AND Provide lighting system controls for all learning spaces to enable adjustments that meet group needs and preferences. This includes classrooms, chemistry laboratories, art rooms, shops, music rooms, gymnasiums and dance and exercise studios. CASE 2. Then in all Classrooms, the project must provide a lighting system that operates in at least 2 modes: One for general illumination and one for A/V situations. 36

5 For EBOM:, the project has to meet the following two requirements: First, provide individual lighting controls for at least 50% of the building occupants to enable adjustments to suit individual task needs and preferences and then Provide lighting system controls for 50% of all shared multi occupant space to enable adjustments that meet group needs and preferences. 37

6 For CI: (same as NC) Provide individual lighting controls for 9o% (minimum) of the building occupants to enable adjustments to suit individual task needs and preferences Provide lighting system controls for all shared multi occupant spaces to enable adjustments that meet group needs and preferences. 38

7 Remember that the operation of automatic occupancy sensors, daylight sensors, and other lighting controls might be adversely affected by items such as office equipment and furnishings that are installed during and after construction. Coordinate the final calibration of these items with the installer and commissioning agent early in the construction phase to ensure that the system operates as intended and provides lighting controls to 90% of occupants. Also remember that lighting system designs should comply with all illumination levels and uniformity requirements recommended by the Illuminating Engineering Society And finally, during building operation, the owner should provide training for building maintenance staff in the calibration of systems and relamping. Property management and building engineers should periodically review lighting systems, as well as conduct surveys to ensure that occupants' needs are met and that lighting and the lighting controls are working according to design. 39

8 Regarding workstation lighting, at a minimum, the occupant must be able to turn the fixture on and off. Ideally, the occupant can easily reposition the fixture and have multiple light levels. In conference rooms, classrooms, lounges, and indoor spaces used for presentations and training, the group should have access to adequate controls to suit their activities. Specific types or numbers of controls are not listed in the credit requirements to allow for flexibility in designing to the specific uses of each project. Meeting spaces must be designed so that occupants have control of their individual area; subdivide these spaces with movable walls or partitions where appropriate. When daylighting is used as a component of an ambient lighting scheme in either type of space, provide glare control, lighting level controls, and room darkening shades as appropriate. 40

9 In making your compliance calculation, remember to include every individual workstation. 41

10 We see here that for this credit, exemplary performance is only available under EBOM. 42

11 Buildings in regions with strong sunlight may need to use less electric lighting by day but require greater controllability in their lighting systems. Because daylight levels may range from the low to very intense during the course of a day, building occupants may experience discomfort if light levels fluctuate widely. Project teams in these regions should consider incorporating passive design strategies, such as good building orientation and the use of light shielding devices like canopies, to control daylight. Daylight sensors that automatically adjust to artificial lighting so to compensate are also effective. 43
