Will compliance with the ASHRAE 62.1-2013 standard be acceptable for LEED v4 projects (even though the credit currently references ASHRAE 62.1-2010)? Where would the USGBC include an interpretation or clarification like this on their website?

Hi Adam, If you double-check the ventilation rates for each of the spaces in your project in both the 2010 and 2013 versions of the standard, and they're the same or more stringent in 62.1-2013, then you should be able to meet the requirements. You can always check current interpretations on the Credit Library page (http://www.usgbc.org/credits), but there's not much there yet for v4! If the situation for your project ends up being tricky, I would use the Contact Us form on the USGBC website or even submit a CIR for confirmation.
