The energy cost offset from onsite renewable energy cannot be used to demonstrate compliance with the prerequisite. Can this cost offset still be credited to the proposed energy cost savings for this credit?

ASHRAE 90.1-2016 and v4

Has anyone used ASHRAE 90.1-2016 as a baseline for a v4 project and know what the adjustment in points would be for this baseline? I know USGBC made adjustments for a 90.1-2013 baseline, but I haven't seen anything for 2016.

LEED v4.1 uses ASHRAE 90.1-2016 so my guess is that you would need to use the v4.1 scale. ASHRAE 90.1-2016 introduces the Performance Cost Index (PCI) calculation so the savings would not align the same way to a v4 project that uses 90.1-2010.
