CI-2009 IEQp1: Minimum IAQ Performance
Hi,
For one of the LEED CI project, the developer has provided louvers with motorized dampers in the AHU for fresh air intake. Can the louvers qualify for fresh air intake? if Yes, then how do we account this in the VRP calcualtion. Or is it necessary the fresh air inline fans to be provided in the AHUs.

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?

Absolutely, that is how outdoor air is supplied by most package units. The multi-zone calculation only needs the total supply air and the amount of that air that is distributed to each zone. The minimum required outdoor air flow determined by the calculation informs what position the dampers have to be set at. AHUs will always provide the same amount of total air. The dampers only adjust what percentage of the air is OA.
