LEED v4.1 allows onsite renewables to contribute to EAp Minimum Energy Performance and offsite Tier 2 renewables to contribute to EAc Optimize Energy Performance. 

This opens up more available points on my scorecard.  

Wonder what the slip would be when going from 2010 to 2016.

For example: 10% better than 2010 = 5% better than 2016. 

anyone have experience with a comparison between the two versions?

I've read through the "Developing Performance Cost Index Targets for ASHRAE Standard 90.1 Appendix G - Performance Rating Method" but it looks like there many factors that influence various versions of 90.1.


My guess is that the difference from 2010 to 2016 will be 'case-by-case' and that a blanket statment "10% hit" by going to 2016 is not accurate.
