NC-2009 IEQp1: Minimum IAQ Performance
We are working on a major renovation project and the restrooms have natural ventilation. Do we have to provide additional mechanical exhaust to comply with ASHRAE? Will having natural ventilation and mechanical exhaust help comply with the IEQ P1 requirements? I'll greatly appreciate any comments. 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?

ASHRAE 62.1 defines exhaust air as air removed from a space to the outside via mechanical or natural means.
Remember to comply with Section 5.1 when using a natural ventilation system.
Also check with local code requirements, our local code does not allow for natural ventilation of restrooms.
