Lighting SystemsScope

• Applies to the design of:

– First installed lighting systems in conditioned or unconditioned spaces

– Altered systems as part of alteration– Altered system that increases the

lighting load if change of occupancy– Exterior lighting systems

IECC 2003 Interior lighting controls

• At least 1 manual control for each area enclosed by walls, or ceiling height partitions

• Must be located in the space• Remote location OK if

– the switch identifies the lights being controlled and– indicates status

Exceptions• Areas that must be continuously lit• Spaces part of means of egress (stairway, corridor, etc.)

Additional Controls

• Additional controls for each area required to have a manual control

• Additional controls include:– Light Reduction Controls, and– Automatic shut-off, and– Guestroom controls (when suits application)

Exceptions– Areas with 1 luminaire– Areas controlled by occupancy sensors– Corridors, storerooms, restrooms, public lobbies

Light Reduction Controls

• 50% load reduction via the following:– Controlling all lamps or luminaires (Dimming – Daylighting)

– Dual switching of alternate rows, luminaires, or lamps– Switching independent lamps within a luminaire– Switching each luminaire or lamp

Exceptions:

• Areas with 1 luminaire

• Areas controlled by occupancy sensors

• Spaces that use < 0.6 W/ sq. ft

• Corridors, storerooms, restrooms, public lobbies, guestrooms
