Can please anybody explain whether Iunderstand this correctly?

In another dicussion I learned that any LEED project team can apply for either the established LEED credit, or the pilot credit, or both - even under LEED 2009 and LEED 2.2 projects, see http://www.leeduser.com/strategy/using-leed-pilot-credit-library#comment....

Am I right in translating this into PC21 by saying that for EQ credits 4.x, already today the new surface/system approach of PC21 can be applied, including VOC emissions evaluation of adhesives, sealants, paints and coatings? And outside North America the AgBB criteria can be applied for VOC emissions, and the EU Decopaint Directive can be applied for VOC content determination? Or did I miss something? And it is free choice for any project team, GBCI auditors will accept this?

Looking forward to your comments.
