regardless of where these spaces fall within in a building. Functionally, a classroom differs from a restroom, so the entire site, including interior and
exterior spaces, should be segregated based on the way the space is used. Similarly used spaces may share basic lighting control needs.
3. How will occupants want to control lighting to best utilize the space?

4. What type of lighting is to be controlled?
If dimming is required, the type of lighting must be considered when selecting a dimmer.
5. When is lighting used?

holidays, inventory, shutdown and other events that may occur only once per year.
6. Is occupancy predictable?
If an area has predictable days and hours of occupancy, it may be best to use a time of day schedule to control lighting in this area. For areas with less
predictable occupancy patterns, occupancy-based control may be required, or a combination of control schemes may best meet the functional needs

control. Understanding the functional requirements as dened by the governing energy code is essential in the planning and design phase. Oversights
at this point could result in costly changes later to bring lighting and lighting control systems into compliance with building codes. In most energy codes,
lighting and lighting control requirements are intermingled, with some codes providing prescriptive lighting control requirements to bring otherwise non-
complying lighting systems into compliance.
8. What are the functional lighting control requirements for each space?
