<p class="MsoNormal">Hey there Nick,<o:p></o:p></p>
<p class="MsoNormal">Weather files such as TMY2 and TMY3 include monthly ground temperature data. I don’t know how the data is generated but I believe it’s based on methodology in ASHRAE Handbook – Fundamentals.<o:p></o:p></p>
<p class="MsoNormal">According to the help documentation, the DHW-INLET-T and DHW-INLET-T-SCH default to the monthly ground temperatures from the weather file. You can create a custom hourly report block to report the ground temperature -ground temp is one
of the global variables. You can also use DOE2 weather utilities to convert weather files to readable text files. For example, STAT.BAT generates a summary of statistical data that includes the monthly ground temperatures.<o:p></o:p></p>

<p class="MsoNormal">Hi everyone,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have a situation where I want to estimate the seasonal <u>
variance</u> in the potable domestic water supply as a function of atmospheric drybulb temperatures. I *think* eQuest has some algorithm to derive 12 (monthly average) temperatures from the weather file data for makeup/DHW purposes… however after scanning
the 2.1e engineers manual and a first pass at trying to find some helpful entry in the resource manual, I’m coming up dry so far.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m trying hoping to source the equations & assumptions used for this estimation, so that I can modify it to fit my project. I’m not specifically married to matching eQuest’s output – any similar process/formulae would be welcome.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Any suggestions?<o:p></o:p></p>
