CI-2009 IEQp1: Minimum IAQ Performance
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.

Is outdoor air quality testing required in a space using natural ventilation?
What options are available to projects outside the US to meet this prerequisite?
Can LEED 2009 projects elect to follow ASHRAE 62.1-2010 for this prerequisite?
Which units should be included in the calculations for this prerequisite?

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
