Good morning,
We have a project that has two cold rooms at -17 and 0 degrees Fahrenheit. These rooms are temporary storage locations of perishable product.
They will be regularly occupied but only for short shifts (around half an hour).
These cold rooms (as with most cold rooms) do not have a fresh air supply to them. It would not be practical to supply fresh air to them, as this would result in huge energy uses and a much more expensive system. The rooms are very large, will frequently have doors opened and closed, and are only occupied by a few occupants
I can find no reference anywhere in ASHRAE 62.1 regarding cold rooms.
Is there anyway in which I can exclude these rooms from the requirements of ASHRAE 62.1 for IEQp1?
I can find no other interpretation result speaking to this.
Also the cold rooms are acceptable according to the local code.
Thank you

We are about to submit a similar project for LEED certification.
We are not providing any fresh air to cold rooms and freezers. Will let you know about the outcome as I exactly have the same question.

ASHRAE Addendum L provides information regarding freezer spaces. If they are not occupied then the area rate =0, no ventilation needs to be supplied. If they are occupied, then 10 CFM per person is required, but only for the duration of occupancy if beyond 15 minutes. 15 minutes would be the threshold for an unoccupied space. See Section 3 of the standard for the definition of occupied space. That's my read on it.
Mehdi: Any word on your project sir?
