  • I understand this. My problem is how do I tell if the space is being used for "environmental air" or is this beyond the scope of this forum.

    It's easy, if the return air is moving above the ceiling, and there are 'registers' to allow the air to enter the ceiling to be transported to the air handler, then it's used for enviromental air. If the return air is not flowing above the ceiling and returning via a duct, then the air is not flowing through the ceiling, then it's not used for enviromental air.
