Public comment drafts of the Minimum Energy Performance prerequisite and Optimize Energy Performance credit under v4 BD+C and ID+C are now available on the U.S. Green Building Council (USGBC) website. The Annual Energy Use credit under BD+C Homes: Multifamily Midrise is also included.

USGBC will be considering the comments on this LEEDuser post to be official public comments.

Comments close January 13.

These updates are about increasing stringency, but that's not all: they also add a greenhouse gas emissions metric. To learn more about what is behind the updates, see our coverage from Greenbuild 2022 in San Francisco: Harder v4 Energy Requirements to Be Balloted in Spring.

Hi.

Compliance with the mandatory provisions of ANSI/ASHRAE/IESNA Standard 90.1–2010 has been in this prerequisite for a long time, but does not meet reality for projects outside the US. I'm aware that we have USGBC-approved equivalent standard for projects outside the U.S.) added to the requirement language, but as the regulations in other countries are usually different, equivalency is very hard to prove.
In addition to inumerous references of US standards, ASHRAE 90.1 mandatory requirements include items that make construction and maintenance more expensive. 
My suggestion would be making the mandatory provisions included in the baseline model only. The design model should comply with the actual legal and engineering requirements of the country or region it is being buit at.

I made a redline copy of the prereq and credit, sharing here to help others dive in :) This does not include the points table or the v4 prescriptive options that got removed.
