Mechanical Ventilation in a Warehouse

Hello,

Maybe this question has already been done, and many times, but can´t find it.

I am modeling a Warehouse which is not conditoned nor heated. It has intake fans to comply with ASHRAE 62.1 and exhaust fans for some specific areas.

The question is: how do I model the Baseline for these fans? Are they process loads for the warehouse or do I have to model them as per Appendix G, G3.1.2.9? and if so, with which baeline system do they match?

Thank you!

They are process fans so the baseline is modeled identically to the proposed design.

Marcus,

I have a question related in warehouse process fan.
Our project team consider process fan consumption (supply, jet, exhaust). The expected that's consumption is so high..
so I'm Under review about ashrae standard, G3.1.1 exceptions e : "Thermal zones designed with heating only systems in the proposed design, serving storage rooms, stairwells, vestibules, electrical/ mechanical rooms, and restrooms not exhausting or transferring air from mechani cally cooled thermal zones in the proposed design shall use System type 9 or 10 in the baseline building design." Is that point isn't related our case? (Out project space is warehouse which is designed only fans, not heating or cooling)
Best Regards,

If you have no heating only spaces in your project then this exception does not apply.
