LEED NC v2009 Comml Bldg Does LEED concern itself with VOCs from treated wood used inside the weatherproofing? If so, what are the VOCs limits for treated wood? Also, does LEED restrict the use of any particular type of wood treatment for use on wood that will be within the envelope? Thanks!

I'm not aware that LEED is concerned with this issue.

Yes, according to Rule 1113, Wood Preservatives maximum VOC 350 g/l

But would the rule only apply to wood preservatives applied on site? and not to, say, treated wood manufactured elsewhere?

A bit of a grey area, a few elements to consider: 1. If IAQ testing is to be performed, treated wood could create a fail, 2. The wood preservative would be required to be provided for EQc4.4, to comply with NAUF requirements,
