Daylight controls in tenant areas

Good question! I am not certain how this is being interpreted by GBCI. Here is our opinion on the fairest way to deal with this issue. If you are not claiming any savings related to the tenant lighting you model the lighting power density identically and don't model the daylighting controls in the baseline. This is a conservative approach. The alternative would require that you develop a typical layout for the tenant spaces and apply daylighting controls to both models since this is a mandatory provision. The later strikes me as busy work for no real effect on savings but technically it is probably how it should be addressed. If you are claiming savings for tenant lighting through a lease agreement then I think you should be required to model the baseline daylighting controls based on a typical layout.
