Hi, we are certifying a new C&S building, in v2009. The version of Ashrae 90.1 to follow is 2007? Or do we have to change to 2010? Also, do you know if Trnsys is an accepted software to modelling in EAc1 and EAp2? Thanks

ASHRAE 90.1-2007 is currently used in LEED 2009 projects. TRNSYS is an accepted software. Appendix G defines the characteristics that the software must process in order to be acceptable.
