CI-2009 IEQp1: Minimum IAQ Performance
Hi,
In our project, a particular zone (Board Room) is being served by 2 systems: central chiller plant through an AHU & by Cassette Units. This additional system was introduced due to additional cfm requirement in that particular area. Please do let me know how do we need to zone this system in the VRP calculator and document.
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?

Yes you need to zone the space in the VRP. Is the AHU's air ducted to the room directly or into the Cassette unit. If the former then just proceed as if the cassette is not there. It is just conditioning the air not changing the ventilation rates.
