Hi All
Anyone have any recent experience modeling for compliance with the US Code 179D?
I am looking for some insight into what version of ASHRAE 90.1 and what path (Energy Cost Budget, Appendix G..) to use for compliance with the US Code 179D Energy Efficient Commercial Buildings Deduction for an existing Retrofit Property (EEBRP) that is over 30 years old and undergoing substantial retrofit.
Any information would be appreciated.
Thank you
