[Equest-users] Reproducing Unmet Hours

[John Aulbach]

Steve:

The NO. 1 thing I have found effective is to increase the deanband in the thermostat. I don't thin USGBC has any problem with that.

It also depends on wheather it is COOLING or HEATING unmet housers. Sometimes, you haven't provided a reheat vaule.

Try those first.

Subject: [Equest-users] Reproducing Unmet Hours

It seems I spend a great deal of time with eQuest trying to reduce unmet hours in a model.  One thing I’ve tried is having eQuest produce an hourly report of a problem zone’s temperature and T-stat setting, exporting the data to Excel and then searching it for patterns.  This approach has a few problems:


	1. I can barely figure out how to create the hourly report I’m looking for.  The reporting function (in the Detailed Data Edit mode, under Project & Site, Hourly Reports) isn’t very intuitive, and I can’t find any documentation on it.  Has anyone found the docs on this?  (I’m currently working through the relevant sections of the DOE 2-2 Dictionary, trying to cross reference between the inputs to eQuest and the BDL file generated from those inputs.  I’m just wondering if there’s a short-cut somewhere.) 
	2. Once I get the data in Excel and do some filtering, I can never get the exported data to match the unmet hours found in report SS-R.  The Excel analysis seems to always overstate the unmet hours.  Has anyone had any luck reproducing the SS-R values?  Any ideas? 
	3. I’d like to hear other user’s experience.  Do you find that resolving unmet hours is a significant part of your modeling time?
