Has anybody used exhaust from public washrooms (no showers/baths) from an air-conditioned building to ventilate its crawlspace? Article 126.96.36.199 of both NBC 2005 & 2010 basically states that all exhaust needs to discharge directly to the outdoors (unless it is directed into a storage garage) - has anybody gotten an exception to this rule with regards to my above described crawlspace ventilation system? I have seen this done on a school in SW Manitoba and I thought it was a pretty good idea to ventilate its crawlspace: has the ability to utilize relatively dry air when outside air is humid (humid air not good for ventilation of crawlspaces), and ASHRAE 62.1-2004 seems to allow this if you consider crawlspace air to be Class 2 or 3 air.
