<p class="MsoNormal">My baseline model requires system 5 from 90.1 app G table G3.1.1A, packaged VAV with HW reheat with 2 boilers. I believe I’ve followed all the instructions from 90.1 but I’m having trouble sizing it properly. I get thousands of unmet heating
hours in every single zone, and my coil heating load from SS-D (-279 kBtu/hr) is less than my total space load from LS-D (-311 kBtu/hr). In addition, it appears that only one of my boilers ever runs.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I feel that I do not fully understand how to properly size systems in eQuest, and can identify the problem but not always solve it. Are there resources out there for system sizing? Also, has anyone had experience with the problem I described
above and might know how to start solving it?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thank you,<o:p></o:p></p>
