Hi Nagaraj, I would complete the VRP calculator using the "100% outdoor air" system, and provide mechanical drawings showing that the whole space is ventilated. Ideally, you should have outdoor air intake louvers on one side of the room and the exhaust grills on the opposite side.  I hope this helps,
