We're working on a LEED Volume prototype for our campus and received this feedback on MRc4: Only up to 10% of the floor area under separate control may be excluded from the calculations, so if residential spaces making up the majority of the building are excluded, this credit cannot be earned.

This is disappointing as we are great with purchasing low-mercury bulbs as a campus but have no real way to track the lamps that students are purchasing or using in personal lamps. I suppose we could do a sweep of all rooms to determine the types of bulbs used during the performance period, but have no way of tracking whether their personal purchases comply with our lamp purchasing plan.

I realize we are supposed to include all lamps, including "portable fixtures," but does anyone see a way around including the residents' personal lamps? Perhaps we could prove that they make up less than 10% of lamps in the building? Thanks
