Scope: 

Scope Applies to the design of the: first installed lighting systems altered system that increases the lighting load if change of occupancy Lighting systems used for specialized commercial, display and emergency use purposes are exempt (Section 805.4.1)

Interior Lighting Compliance: 

Interior Lighting Compliance Mandatory Requirements Controls Switching Interior Lighting Power Requirements Entire Building Partial Building Total Connected Power (805.4.1) Interior Lighting Power (805.4.2) < The building complies if its total connected power is no greater than the interior lighting power. and

Interior Lighting Controls: 

Interior Lighting Controls Lighting controls required for each area enclosed by ceiling height partitions Switch locations In view of lights “On” or “off” indication from remote location Occupancy sensor Section 805.2.1

Interior Lighting Controls: 

Interior Lighting Controls Exceptions Emergency/security lighting Stairway or corridor lighting for egress Section 805.2.1

Additional Controls: 

Additional Controls Each area with mandatory controls must have: Light reduction controls (805.2.2.1) included in 2003 Automatic lighting shutoff (805.2.2.2) 2001 Supplement Guestrooms (805.2.2.3) included in 2003 Exceptions Areas with only 1 luminaire Areas with an occupant-sensing device Corridors, storerooms, restrooms, or public lobbies Section 805.2.2

Bi-Level SwitchingLight Reduction Controls: 

Bi-Level Switching Light Reduction Controls Areas that are required to have manual control shall also Reduce connected lighting load uniformly by 50% for each space Exceptions Area has one luminaire Occupancy sensor controls area Area is corridor, storeroom, restroom, or public lobby Guest rooms Spaces that use less than 0.6 Watts per square foot (in 2001 IECC requirement applied to areas < 250 ft.2) Section 805.2.2.1

Bi-Level Switching: 

Bi-Level Switching Compliance Examples

Bi-Level Switching: 

Bi-Level Switching Compliance Examples Example: Alternate Lamps (a/b) Example: Dimmer Control Option

Automatic Lighting Shutoff: 

Automatic Lighting Shutoff In buildings > 5000 ft2 must have automatic control devices to function either on Scheduled basis using time-of-day Unscheduled basis by occupant intervention In 2001 IECC requirement for spaces >250 ft2 in buildings larger than 5,000 ft2 Section 805.2.2.2

Occupant Override: 

Occupant Override Where automatic time switch control devices are installed to comply with Automatic Lighting Shutoff, device shall be equipped with an override switching device that: Readily accessbile Located so that person using the device can see the lights or area controlled by the switch Manually operated Allows lighting to remain on for no more than 2 hours when an override is initiated Controls an area <5,000 square feet Some Exceptions Section 805.2.2.2.1

Holiday scheduling: 

Holiday scheduling If automatic time switch is installed: Automatic holiday scheduling feature that turns off all loads for at least 24 hours and then resumes to normally scheduled operation Exceptions Retail stores and associated malls, restaurants, grocery stores, churches and theaters

Guest Rooms: 

Guest Rooms Master switch required at entry Section 805.2.2.2 Standard Room Suite

Exterior Lighting Controls: 

Exterior Lighting Controls Automatic switching or photocell controls shall be provided for all exterior lighting not intended for 24 hour operation. Automatic time switches shall have a combination Seven-day and seasonal daylight program schedule adjustment A minimum 4-hour power backup

Tandem Wiring: 

Tandem Wiring Exceptions Luminaires with electronic high-frequency ballasts Luminaires not on same switch controls or not in the same area Section 805.3 Center to Center

Exit Signs: 

Exit Signs Internally illuminated exit signs shall not exceed 5 Watts per side Section 805.4

Interior Lighting Power Requirements: 

Interior Lighting Power Requirements Mandatory Requirements Controls Switching Interior Lighting Power Requirements Entire Building Partial Building Total Connected Power Interior Lighting Power < The building complies if its total connected power is no greater than the interior lighting power. and Section 805.4/805.5

Total Connected Power: 

Total Connected Power Total connected lighting wattage includes: Lamp wattage Ballast wattage Sources of bulb/ballast wattages Manufacturer’s literature Industry default tables Exceptions Specialized medical, dental, and research lighting Professional sports arena playing field lighting Display lighting for gallery exhibits, museums, and monuments Guest room lighting in hotels, motels, boarding houses, or similar buildings Emergency lighting automatically off during normal building operation

Interior Lighting Power: 

Interior Lighting Power Mandatory Requirements Controls Switching Interior Lighting Power Requirements Entire Building Partial Building Total Connected Power Interior Lighting Power < The building complies if its total connected power is no greater than the interior lighting power. and Entire building Building is all one occupancy or a majority occupancy exists (Section 101.4.3) Tenant area or partial building Use for tenant spaces in larger building or divide whole building into area types Table 805.4.2/Table 805.5.2
