<p class="MsoNormal">Every building is obviously quite different, but I was involved with logging indoor and outdoor humidity levels in a new near-passive residence recently, and am posting the results as an image (assuming that an image can be posted here).
There was an extremely high correlation between average indoor and outdoor humidity levels in the month of Dec 2017 (look at slopes of the two values, which are both absolute humidity levels). There is significantly less variability in the indoor levels than
the outdoor levels. I guess this speaks to the ability of indoor components to absorb moisture and provide a dampening effect on the outdoor humidity variations.<u></u><u></u></p>

<p class="MsoNormal">Hello Ibrahim,<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">If it’s an existing/built building, you’ll want to acquire a quantity of these to measure directly:
<a href="http://www.onsetcomp.com/products/data-loggers/ux100-003" target="_blank">http://www.onsetcomp.com/<wbr>products/data-loggers/ux100-<wbr>003</a>. Very useful for objectively quantifying occupant comfort issues and operation/malfunctions of building or space-level humidity
controls, which can then support energy savings/costs associated with correcting those kinds of issues.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">If it’s a new building or else only on paper at the moment, any number of energy simulation software can report temperature and RH of airstreams at a system or zonal resolution. eQuest/doe2 is among them, however I’m inclined to suggest/request
you to be more specific about your purpose and end-goals, supplemented with any existing building simulation experience/skillsets. eQuest comes with a definite learning curve before it’s outputs can be leveraged with confidence, and there might be software
more purpose-built options appropriate to your task(s) at hand that I or others could suggest.<u></u><u></u></p>
