[Equest-users] Heating Hours Unmet

[Nisonger, Kyle M NWK]

John,

I've attached the two files you requested, but I don't think they are
necessary because my parametric runs only incorporate rotating the building
to meet LEED.

Thanks for your help, sorry for the confusion.

Kyle:
 
We need the.INP file, not the -2.INP file. It also appears with that, you are
running parametrics. We also then need the .PRD file as well.

	I have assigned each zone it's own single zone system, but I still am
coming
	up with about the same number of unmet hours.  I can manually adjust
the
	design cfm to lower them, but this seems futile trying to play around
with it
	to get it just right.  Shouldn't eQuest automatically size the equip.
and
	cfm's to meet the load?  Another question I have is why doesn't the
percent
	of hours outside of the throttling range on the BEPS report match up
with the
	number of unmet hours on the SS-R report?  I have attached my project
files
	if anyone has time to look at them.  I appreciate your help.
	
	Thanks,

	Kyle,
	
	
	
	Try this first: eQuest expects a single-zone system to serve just
that - a
	single zone.  You'll need to have a separate single zone system
created for
	each zone you need to assign to that system.  Once that is done,
eQuest will
	then be able to address the thermostats in each zone adequately and
you
	should see a rather dramatic drop in your unmet heating hours,
possibly
	eliminating them altogether.
	
	
	
	After that, if unmet heating hours remain there are a number of other
things
	to look at.  Let us know if the above works first.

	Equesters, 
	
	I have a packaged single zone system using DX cooling and Furnace
heating
	that serves 7 different zones and is controlled by the corridor zone.
This
	is supposed to replicate "System 3" in ASHRAE 90.1 appendix G.  I
have many
	unmet heating hours (including my system control zone).  I have let
eQuest
	auto size equipment capacities and and cfm. I have tried doing
everything I
	can think of to reduce the number of unmet hours.  My OA volumes are
pretty
	small and shouldn't be affecting it.  I expected possibly a few unmet
hours
	in some of the zones, but not in my control zone, the corridor, and
not to
	this magnitude.   I get the following warning message seen below, I'm
not
	sure what it means by "Baseboard-Rating"?  Any ideas on what this
means or
	how I could reduce the number of unmet heating hours?
	
	
	
	
	
**WARNING********************************************************************
	** 
	             ZONE EL1 Food Storage Zn (G.S2)      
	             might have insufficient heating capability. 
	             Check that the SYSTEM or ZONE HEATING-CAPACITY plus this

	             ZONEs BASEBOARD-RATING is adequate to maintain the ZONE 
	             specified DESIGN-HEAT-T for the calculated peak ZONE
load 
	             (see LS-A or LS-B for the ZONE peak load.) 
	
	
	
	Thanks for your help,
