Is the building designed for maximizing daylight penetration, or are we “getting what we can?” 2. Do I have adequate daylight illuminance to warrant lighting control? 3. Are the light fixtures circuited to facilitate control? 4. Have I provided separate control zones for teaching areas and/or display walls? 5. Have I provided the necessary manual override controls? (lighting and windows) 6. Am I controlling the system in a manner that will not disturb occupants? 7. Have I complied with energy codes? 8. Have I considered start up and commissioning?
