With Option 1, Path 1, we are expected to flush-out 14,000 cf/sf of outdoor air at 60 degrees temp. and 60% humidity min. Is there a minimum ventilation rate as with Path 2 which is 0.30 cf/min.? Our project just happens to have some extra time and we thought we would have to meet the after occupancy requirments (which we could not, based on the design of the HVAC in the base building). I believe it would be a manner of calculating the corrent amount of time to meet the 14,000, but could go to a lower outdoor air of o.15 cf/min. as this is the maximum output of the original system. Your thoughts?

There is no minimum ventilation rate for Path 1. Just create a Flush Out Plan In writing, execute, trend the measurements in the space, and document.
