(1)   Controls. These are department rules in addition to the requirements in IECC section 505:

(a) General. Except as provided in par. (b) , daylight zones in any interior enclosed space greater than 250 square feet and a lighting density more than 0.6 W/ft 2 shall have at least one control that meets all of the following requirements:

1. Controls only luminaires in the daylight zones.

2. Controls at least 50% of the lamps or luminaires in the daylight zone, in a manner described in IECC section 505.2.2.1.

(b) Exceptions. The requirements of this subsection do not apply to any of the following:

1. Daylight zones where the effective aperture of glazing is equal or less than 0.1 for vertical glazing and 0.01 for horizontal glazing.

2. Daylight zones where existing adjacent structures or natural objects obstruct daylight to the extent that effective use of daylighting is not feasible.

(2)   Line-voltage lighting track and plug-in busyway. Substitute the following for the requirements in IECC section 505.5.1.4: The wattage of line-voltage lighting track and plug-in busway which allows the addition or relocation of luminaires without altering the wiring of the system shall be the volt-ampere rating of the branch circuit feeding the luminaries or an integral current limiter controlling the luminaires, or the higher of the maximum relamping rated wattage of all of the luminaires included in the system, listed on a permanent factory installed label, or 30 W/linear foot.
