CI-2009 IEQp1:Minimum IAQ Performance

IEQp1 VRP Calculator

Greetings, Regarding IEQp1 and VRP Compliance Calculator there is a question on how to enter an AHU having the following characteristics: The AHU is a constant volume device; supplying to several rooms, but with one and the same temperature; It is 100% OA unit. The question is: Should such AHU be entered as "Single Zone Unit" or as "100% Outside Air". Thanks.

Vassil, this should be modeled as a 100% outside air system, which will simplify some of the calculations.

Thanks for the reply. Regarding the simplicity of calculation, the Single Zone is even more simpler than 100% OA. Besides, the AHUs for these zones are the only HVAC equipment to cover the thermal loads there and that was the reason for the question. Thanks
