Hello Modelers.
 
I am looking for information/experience with applying the ASHRAE
90.1-2004 , Appendix G for labs. 
 
It is well known that  Appendix G cannot be used properly for labs. The
ECB and Labs 21 fixed many of the problems and now they are part of the
2007 version ( not as addenda to the 2004 version). USGBC refers to the
2004 version , but also allows the use of 2004 addenda (per USGBC memo
from April 26 2007). I am wondering if anybody knows what is the
position of USGBC regarding the 2007 appendix G changes. 
 
Thanks  
 
Itzhak
