				General Notes on Lighting System Design and Enforcement of Table 305.B
a. For design in new and significantly
				renovated schools, the designer shall utilize the Illuminating Engineering
				Society of North America (IESNA) Lighting Handbook; however, the standards
				contained in Table 305B of this Part shall control if there is a
				conflict.
b. Enforcement of the
				lighting standards is based upon the average illumination level in each room or
				area.
c. For instructional spaces
				utilizing digital "smart boards" or outfitted for audio-visual presentations,
				the designer should consider the installation of lighting controls readily
				accessible to the instructor having capability to reduce the illumination on
				the screen to seven footcandles or less, while maintaining an average of 20
				footcandles within the remaining functional areas of the room or
				area.
d. For instructional spaces
				utilizing dry-erase whiteboards, the designer should consider the installation
				of separately controlled, dedicated luminaries mounted parallel to the
				whiteboard, providing 30 footcandles average on the vertical plane of the
				whiteboard.
