[Equest-users] Estimating groundwater temps

Mon Mar 4 05:24:23 PST 2019

Hi Nick,
I use the 1 meter ground temperatures reported by eQuest. eQuest will estimate the monthly ground temperatures from the weather file is not explicitly listed in the .inp file. 1 meter is likely not deep enough for most locations but it does illustrate the lag in ground temperature from the outdoor air temperature. The .epw file also includes ground temperatures.

Hi everyone,

I have a situation where I want to estimate the seasonal variance 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.

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.

Any suggestions?

~Nick
