I am going to show how uneducated I am with eQuest…I was able to reduce my
unmet hours on my baseline case by autosizing the equipment. Now, I’m having
problems with my proposed case. I finally looked at the PS-A report and it’s
showing that my heating and cooling are not coming on at all. I don’t even
know where to start changing controls in detailed mode. My systems are 5 split
system single zone heat pumps. The hours are only showing up in one room per
system (and these rooms have no significant loads). I’ve tried changing the
control space and it does nothing. Also, this is the error showing up every
time I run the simulation:<o:p></o:p></span></p>

<p class=MsoNormal>Don't know what is "legal" in LEED, but try
reducing your semsible loads fraction for the kitchen and laundry down (say to
0.1). Perhaps assuming much heat goes out the exhausts for these items.<o:p></o:p></p>

<p class=MsoNormal>Hello everyone. I’m working on a baseline 2-story
residential model using PTAC’s for LEED. I’m having problems complying
with the unmet hours in several locations. I have commercial cooking
equipment and laundry machines as my only large loads. I have entered my
calculated heating and cooling capacities and my calculated CFM for each space
into detailed mode. To help with my unmet hours, I bumped my sizing ratio
up to 1.25 and set my throttling range at 6. Still high unmet
hours. I was wondering if there is a way to switch heating and cooling
capacities back to auto-size from detailed mode or do I just have to bump my
capacities up until they cover my hours?<o:p></o:p></p>
