PNNL Re-Tuning Methodology

Shane, It's not that they are different. It was not my intention to suggest that it be a pilot credit in the sense that it's some thing different. It could be a extension to the existing credit then ? In any case, it's more about the PNNL approach being a complete and self-contained process. Compliance and adherence to the PNNL approach should be sufficient with out requiring us to jump though more hoops in terms of documentation ? Take the NC EAc1 credit for example - there are 3 different approaches that can be used - each option originating from a different organisation yet with the same goals in mind ? I guess my argument also involves EBOM EAc2.1 too. As LEED goes international, there is no harm in having many different options either, to cater for the different approaches around the world.
