I'm working on a Auditorium and classroom addition for a High School. I have to use Option 3 and want to get clarification on the theater space. On page 559 it states "Dedicated theater spaces (not multipurpose rooms) must meet an illuminance of 10 footcandles, as recommended in the IESNA Lighting Handbook Reference and Application". I'm assuming the "Auditorium" in this case would be classified as a "theater", does that seem appropriate? I've been in a number of school theaters and I cannot think of one that had windows. For this project, it appears the "Auditorium" will eliminate this credit. Any thoughts?
