Sambhav,<br><br>There is a range of cfm/sf depending on type of space, etc. A really good resource for them is a little book that ASHRAE publishes that has all kinds of "rules of thumb" in it, although I just looked for it in their publication catalog and didn't see it, <br>
<br>Anyway, it depends of type of space, space usage, whether it is an interior or exterior space, etc., and seems to hover around 1 cfm/ft. It has always made me wonder why the eQUEST default is 0.5 cfm/sf, because that number in almost all cases will be too small. Since we're dealing with Q = 1.08 cfm delta T a lot in our annual energy calculations this points to a high probability that the hours of cooling/heating will be outside of their throttling range. I almost always raise the cfm/sf right away when I start a model.<br>
<br>Hope this helps,<br><br>Carol</p><div><p class="MsoNormal">On Thu, Mar 3, 2011 at 4:18 AM, sambhav tiwari <<a href="mailto:tiwari.sambhav@gmail.com">tiwari.sambhav@gmail.com</a>> wrote:</p><p class="MsoNormal">Hi All,<br>
