VOC budget shortcut

You can do the VOC budget method to prove you've offset the one product. No need to do all products in this credit.

See EQc4.1 LI# 1822, dated July 7, 2007.
The Inquiry includes the question, "If a VOC Budget calculation becomes necessary, is it sufficient to demonstrate that low emissions from a limited number of low-VOC products offset excess emissions of a few non-compliant products, without calculating emissions for EVERY applicable product on the Project? . Similar issues with...VOC Budgets exist in...EQc4.2"
The Ruling states that this question is inquiring "whether all adhesive and sealant products are required for the VOC budget calculation. In this case, if VOC emissions from a few products can be offset through VOC budget calculation with VOC emissions from a different set of products due to the scale of application, the project is not required to include all other adhesives and sealants used in the project in the VOC budget calculation. Applicable Internationally."
This interpretation was under LEEDv2.1. I believe that the abbreviated VOC Budget calculation has been incorporated into the current 2009 LEEDonline Credit Forms, so I am not sure that citing the LI is absolutely necessary. To be safe, citing the LI couldn't hurt.
