Not to hi-jack the thread, but we are undertaking a study currently comparing 90.1-2016 Appendix G results within the new LEEDv4.1 rating system and projects we have completed under 90.1-2010 Appendix G for LEEDv4. The results are not pretty.
A project which achieved 16 points in v4 is achieving 3 points in v4.1. That's with energy & carbon. This an office project, climate 4A, really great envelope, well designed shading, 50% lighting reductions, and decoupled DOAS + Air-source VRF. While the study is on-going and we are going to look at more project types & climates; I'm not real sure how I can 'sell' this to teams that 'hey, this is a great building, and you get no LEED points.' More projects will be going LEED prescriptive; which is fine, but isn't an energy model. And 'just add renewables' isnt a solution to every job.
Has anyone else done this study on their projects yet?
