Who can help to clarify? I am in a discussion with consultants who state that for paints and coatings, wet-applied on-site on walls, floors and ceilings, the VOC emissions requirements and the VOC content requirements stand as alternatives.
But I read from rom the credit: Threshold "At least 90%, by volume, for emissions; 100% for VOC content". And I read "In addition to meeting the general requirements for VOC emissions (above), on-site wet-applied products must not contain excessive levels of VOCs, for the health of the installers and other tradesworkers who are exposed to these products."
In my reading, the VOC content requirements are not an alternative, they are additional to the emissions requirements; and I remember from my time in EQ TAG that this was the intention when we wrote this wording.
My discussion partners now say that the LEED APs are satisfied if paints and coatings fulfil the VOC content requirements and then they do not require compliance with the VOC emissions criteria. In Europe this means that all paints and coatings would qualify automatically because they all have to comply with European law, here with the European Decopaint Directive (2004/42/EC), which is one of the options to show compliance with the VOC content requirements - even if they are emitting large amounts of VOCs.
Is there any official US GBC statement on this? And - do the LEED APs know about this change from LEED 2009 to LEED v4? How would GBCI handle project documentation regarding paints dealing only with VOC content, not with VOC emissions?
And one additional question: I am hearing that almost no paints had been AgBB-like VOC emissions tested. Well, I know of some ... but please would you kindly report your experience whether you are receiving documentation on VOC emission testing of paints and coatings when you ask for it?
