It seems to me there are two distinctly different sources of
"infiltration" through a revolving door - <br>
(1) leakage through the cracks and imperfect seals<br>
(2) bulk air exchange when the door is used and acts like a piston
bringing in Pi*(r2/4)*ht volume of outdoor air and exhausting the
same of indoor air. <br>
<br>
The relative importance of the 2 depends entirely on how much the
revolving door is being used. <br>
It might be interesting to do some back-of-the-envelope calculations
to see. <br>

</div>
<div>
<p class="MsoNormal"><span style="color:blue">For this one
can do peak load calculations and try to find out the
cooling load requirement of any space at desired time.</span><o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><span style="color:blue">I have also
referred ASHARE 90.1 and have found that the swinging
door has 1 cfm / sq. ft. and windows have 0.40 cfm / sq

<div>
<p class="MsoNormal"><span style="color:blue">eQUEST have
the option to input the required infiltration in
Internal load tab and input it in as cfm /sq. ft for the
space.</span><o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><span style="color:blue">The
infiltration being input is the total infiltration in
that space.</span><o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><span style="color:blue">You need to
have proper weather file as per location, have some
cooling system as per project and proper infiltration as
input.</span><o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><span style="color:blue">Then from the
hourly report being derived from the File< Export
File< Hourly result (CSV) and have the finding in
cooling end-use energy.</span><o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><span style="color:blue">This will help
you to find out whether that space at any desired time
needs the cooling or not. Additionally one needs to have
proper schedules.</span><o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><span style="color:blue">The better
software to have these kind of analyses is IES-VE but
eQUEST can also help.</span><o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><span style="color:blue">The design
time is the cooling load having the most peak value of
cooling energy in Hourly report.If the Cooling
requirement is less than 300 hours over the year then
may be you can ignore installing cooling system.</span><o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><span style="color:blue">If it is for
the major part of year then you can choose to have
cooling system. Also have a go on the cooling plant
requirement size.</span><o:p></o:p></p>

requires to do a thermal simulation for a two-story
atrium/staircase to check if the cooling system is
required for it. The atrium has a revolving door, which
revolves once every 30 minutes, and the swing door opens
for 30 minutes every 8 hours for shift change. My
question is how to simulate the revolving door and swing
door in eQuest? I noticed that ASHRAE 90.1-2010
mentioned the infiltration from these two types of doors
is 1.0 cfm/ft2 tested at a pressure of at least 1.57
pounds per square foot (psf), but I do not quite
understand what this means and how to use this number in
my model. If any one has an idea, please give the
comments. Thank you so much!</span><o:p></o:p></p>
