LEED requirement says that Lighting for any presentation or projection wall must be separately controlled. Our project have small multiple meeting room where hanging on the wall TVs are used for presentation. As meeting room are small (4-6 person capacity), the engineer don't plan to design separate control for presentation wall. Besides, as presentation tool is a TV, lighting adjustment can be made on the TV to optimise visibility of the screen while occupants have enough light to take notes. Is it essential to have Lighting control for presentation wall? Tks
