[Equest-users] How to model VAV boxes and Parallel PIU boxes in one RTU

[Morteza Kasmai]

Hi Brian,



For EAp2 we have to use Section 11 but to achieve EAc1.3 (Optimize Energy
Performance – HVAC) there is an option that allows you to use Appendix G.
Following paragraph is from page 171 of the reference guide.



Thanks,

Morteza
