Footnotes to Table 305.B

1. 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.La.
