LEED Reference Guide For Green Interior Design And Construction says in chapter EAc1.3 (# 6. Calculations) on p.168 that the standard has 2 energy comparison methods, both of which are appropriate for demonstrating energy cost savings to earn this credit. They are refering to the ECB method and the Performance rating method.
As I understand this are two dofferent methods. In my case I want to use the BPRM since I've already done this calulation for the CS-certification. But when I am about to fill in the form on LEED Online I can only see options for how to report the ECB-method. They want me to provide the ASHRAE Interactive ECB Compliance Report. I don't understand how to do the report when not using the ECB-method, but BPRM.
Can anyone help me to clarify this?
