<DIV><FONT size=2 face=Arial>Here's another opinion (non-authoritative): I
believe the VRV efficiency requirements would match best with the "air cooled,
cooling and heating modes" requirements in Table 6.8.1B (for heat pumps).
In the ECB method, this would most likely be system 8, Packaged terminal
heat pumps. I agree that the ventilation should be modeled separately as a
DOAS.</FONT></DIV>

<DIV>Well, there seems to be no ARI standard for testing VRV yet. So, you won't
find it in 90.1. </DIV>
<DIV>The closest you can get is packaged single zone (match cooling
capacity) i believe but you'll have to figure out a way of modelling the
fresh air side- as DOAS or others. </DIV>

<DIV>Hi to all!</DIV>
<DIV> </DIV>
<DIV>Where can we find the Minimum Requirement System Efficiency of a VRV
System in ASHRAE 90.1?</DIV>
<DIV>Which of those systems mentioned in the ASHRAE 90.1 can we use to compare
such equipment?</DIV>
<DIV> </DIV>
