NC-2009 IEQp1: Minimum IAQ Performance
I am having troubles understanding what is a single zone system and a multiple-zone system and how to fill out the forms. Example: I have a zone with eight individual offices and corridor on a air handler and another zone with restrooms, library, records and corridor fed from a different air handlers.

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?

1.A single zone is when a fan is providing outdoor air for a unique zone, for instance a dinning room. In this case you should complete the ventilation calculator in the LEED form.
2.A multiple zone is when a fan is providing outdoor air for different spaces at the same time (restrooms+library+records+corridor...). In this case you should use the excel calculator (.xls file) downloadable from this web and upload it to LEED online.
