AIR ECONOMIZERS AND SERVER ROOMS

Hello everyone, I’m working on a Commercial Interior Project following the simulation´s path, in section 11.3.2 item e, says: “Budget Building system listed in table 11.3.2A shall have outdoor air economizers or water economizers, the same as in proposed building, in accordance with section 6.5.1.” therefore I don’t have to simulate any economizer if I don’t have any in my Propose Building Design? In the same project there is a Server Room, I’m not sure how to simulate its HVAC system. In the appendix G in section G3.1.1, exception b it refers to spaces like server rooms can have an independent HVAC system, however, in chapter 11 there isn’t any section related to Server Rooms. I don’t know if I have to model different HVAC system for the Server Room or include it within the HVAC of the overall project. Thanks for your advice.
