90.1-2010 Appendix G - Systems Type 5-8. Based on G3.1.3.13 and G3.1.3.14 I have interpreted this as A Single Max - Single Min VAV Box control strategy. This is reinforced by the 90.1 PRM - Guide from PNNL (PNNL-25130), Section 3.5.5.1, which explicitly states Single Max at 30% minimum. I am getting push back from a Peer Review that this is wrong and since my Proposed has a mix of Single Max and Dual Max boxes, the Baseline Boxes should be the same control logic. They (properly) points out that the PNNL Guide isnt officially part of 90.1-2010. Which, while accurate, is pretty poor since IMO its a pretty good guide and appears to have been coordinated with ASHRAE and GBCI.

So - VAV Box Type & Controls in the Baseline - Single Max Single Min? Single Max dual Min? Dual Max Single Min? dual Max Dual Min?
