CI-2009 IEQp1: Minimum IAQ Performance
Hi all,
We have a small LEED:CI project in a CS certified shopping mall. We don't have any direct outdoor air intakes, we take the air from the main atrium and give it to our space. The base building has even achieved increased ventilation credit by natural ventilation, so air in atrium is quite acceptable.
How can we document compliance with this prerequiste?
Thank you!

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?

Aaron, you'll want to see if you can find out the outside air percentage in the air distributed to the atrium. ASHRAE 62 does allow you to use transfer air to meet ventilation requirements in certain cases, with a zone air distribution effectiveness of 0.8 if you're transferring air from the opening of the store to the back of the store.
