For LEED energy analysis, will the ASHRAE reference change to 90.4 instead of 90.1?

Whole-building energy simulation Demonstrate a 5% improvement in the proposed performance rating over the baseline performance rating. To determine total energy cost savings, model two systems, one for building energy cost and the other for IT equipment energy cost. Calculate the baseline building performance according to ANSI/ASHRAE/IESNA Standard 90.1–2010, Appendix G, with errata (or a USGBC-approved equivalent standard for projects outside the United States), using a simulation model for the whole building and data center modeling guidelines. Determine the power utilization effectiveness (PUE) value of the proposed design. For this prerequisite, a minimum of 2% of the 5% energy savings must come from building power and cooling infrastructure. Projects must meet the minimum percentage savings before taking credit for renewable energy systems. The proposed design must me...
