We have a space about 5000 ft2 for about 160 people. It is a true open office; no cubicles, no walls, just long rows of tables & chairs. Could this be considered a single space for lighting (and thermal control)? It seems that there should be some individual controllability, but there is no way to reasonably sub-divide the space, and 160 desk lamps would be too expensive. Is IEQ c6.1 possible here?
