Yes, this scenario would meet the credit requirements. The intent is for the building to have automated control over the major building systems, not that one system controls everything. If a building has areas with distinct usage patterns (i.e. an arena), then it is reasonable to have another BAS controlling the functions related to that space. Make sure that HVAC and lighting is controlled for the entire building and that the system has a user interface that provides trend information.

Question
My project has a BAS for the main building HVAC and lighting, but then a separate BAS for an attached arena’s HVAC and lighting. Would this meet the credit requirements?
