[Equest-users] eQUEST unconditioned spaces

[Dakota Kelley]

Amber,

 

If I’m following your description, you must be specifying the unconditioned zone in Shell Wizard/Screen 2/Zone Characteristics button.  Then you’re obviously specifying system-per-floor in the HVAC wizard.  This sounds like it should work, but what is happening is Shell Wizard/Screen 14 settings are trumping Shell Wizard/Screen 2.  There are two solutions:

 

1)      Simply change the zones to unconditioned in the detailed interface.

2)      Create a new zone group in Shell Wizard/Screen 14.  Assign the unconditioned zones to this group, and then make sure the “Conditioned” check box is not checked.  Assign the group to whatever system makes sense and move on (making sure that at least one conditioned zone group is also assigned to that system).  All zones have to belong to a system, but if they’re unconditioned their parent system is irrelevant.  This method is only slightly longer than the one above, but it lets you stay in the wizard.

 

If you try to leave an unconditioned “on its own”, which I interpret as being assigned to its own single-zone system, you’ll get an error saying every system has to have at least one conditioned zone.  Let me know if I have misunderstood you.

What is the best way to handle unconditioned spaces in eQUEST?  Right now, I am zoning it separate and calling it unconditioned in the WIZARD.  Then, when I assign systems, I am putting the unconditioned zone in a system with a conditioned space and saying “ one system per floor”.  Is this the proper way to do it?

 

I have tried just leaving the zone as unconditioned and on its own, but then when I do the “permit submittal” calculation it still asks for the fan flow and cooling capacity for that zone.
