HI, The client requesting to have DX air conditioning system for each space in the building. My questions: 1. Could I use the sliding door as operable wall/window to supply the fresh air? 2. Do we need to concern about the fresh air to the other rooms which do not have the conditioning system? Thanks in advance

Yes, sliding doors can be used as operable windows to meet the 4% min; however, you must also verify that these and other openings are at least 25' away. If not those areas will require mechanical ventilation or a combination of mechanical & natural to comply.
