We have a project that is a large outdoor amphitheater, with a roof, but an unconditioned outdoor space. It has an adjoining building for all of the back of house uses. When calculating the occupancy, how does the outdoor seating get calculated? Is it included or not? In particular, we are having some trouble reconciling the occupancy against the WEc1, because the back of house has its own internal wash room facilities, but also has additional wash rooms that are externally accessible for users of the amphitheater space. It is a fairly large facility so the amount of fixtures is substantial.
