[Equest-users] Anyone have trouble opening eQuest files in Windows 8.1?

[Nathan Miller]

I'm only running measly Windows 7,  but for most recent versions of Windows, it helps if you run eQUEST in compatibility mode, I believe the "Windows XP (Service Pack 3)" option works. 

Again, I'm not sure of how to get there in Windows 8, but in my version of windows, if you right click on the .exe file for eQUEST you can select the compatibility tab from the window that pops up, tell Windows to "Run this program in compatibility mode" and then select which versions of compatibility mode to try. If you've already done this, then I am out of ideas.

I sent normal 3.64 files to a colleague and he says he cant open them. Any thoughts?

I have the vague impression that "maximum tracked changes" messages have something to do with the user interface and do not generally seem to affect an actual simulation (erroneous warnings).  I've encountered the same warning across many projects without any apparent detrimental effects.

I don't think I've seen this warning addressed in any official capacity however, so it would be prudent to maintain a backup of your project prior to or immediately after receiving this message for the first time, and take note of what change evoked that response, in case you later want to backtrack.

I'd reinforce Patrick's response, and also layer on to consider pressure drop / fan heat while you're at it...  Fred Betz summarized this pretty well a few months ago (attached).  It's tempting to assume a cooling energy "jump" must be solely caused by additional outside air loads, when adding ERV, but your fans working harder can easily be a good chunk of that figure as well.

how is the erv controlled?  if you take the default on when ahu supply fan unit is on then it will cost you more energy as the erv runs continuously even when there is a) no advantage to do so, and b) when it is detrimental to do so.  try changing control to a delta t between exhaust air and outside air temp via a eem & play with the delta.  my experience in southern arizona is that a 27 d t is optimum where i am at.

Hi Group,

My system is a simple VAV. When I click to add an ERV, it ties up my machine completely for about 3-4 minutes and then throws up the error for "maximum number of tracked changes exceeded."  But it accepts the ERV and lets me configure it.  This results in a vast decrease in heating energy, but a large increase in cooling energy. Weather is Atlanta.  I don't understand why cooling energy would increase with the simple addition of an ERV.

Any thoughts?

Thanks!

Dave
