The 30% increase in ventilation above ASHRAE 62.1-2007 is a good idea in dry climates. Our issuse is that we have several projects that are seeking LEED Silver with client (GSA) demanding the increased ventilation credit be applied. Since most of these projects are located in southeastern humid climates we are concerned that even with ERVs our system loads will demand too much additional tonnage and dehumidification to be prevent mold concerns. Has anyone addressed these concerns and is there a reference in the LEED V3 manual where this is noted so we may reflect such to our owner?
