Hi,

Im currently engaged in the design on a new project where we are falling in a dilemma with the HVAC design team about what spaces should be supplied with fresh air.

This conflict has come up due to some unreasonbale design requirements given by the client and I want a clear reference that clearly defines what spaces should receive treated fresh air.

I know that ASHRAE 62.1 has given a clear reference to all types of applicable spaces, however, it doesnt say anywhere that supplying fresh air to any unoccupiable space is incorrect. Is there a clear reference that further explains and defines this ?
