correctly?<o:p></o:p></span></p>

<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I have another question about whether people have gotten
wind speed to have an effect on crack infiltration.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Below is an hourly report for a few hours of January 1<sup>st</sup>.
I have a building set up with each space’s infiltration based on the
crack method, with an infiltration schedule of all 1.0s. Exterior walls
are set up with crack coefficients pretty high (leaky building) – the
coefficient is about 7.5, which corresponds to a 0.6” crack around the
entire perimeter of the wall (it’s a leaky corrugated metal wall
construction).<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>This report is for a typical west (270) facing wall, about
45 feet by 8 ft tall. 70 feet below the neutral level. As expected,
there is CFM infiltration, which is great. The CFM values decrease as you
go up the building (12-story), which is perfect. Means the whole crack
method vs neutral height is working. However, there appears to be NO
impact of the infiltration based on wind speed. The CFM for this given
wall is entirely dependent on the OA DB temp, and does not change at all with
wind speed. See below. Highlighted areas show similar temp hours
but with varying wind speed. CFM for this 1<sup>st</sup> floor exterior
wall doesn’t change at all with differing wind speeds. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I thought that the crack method was supposed to alter CFM
based on wind speed, but NOT alter based on difference in indoor and outdoor
temp.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>What am I doing wrong here? For a leaky building, wind
speed SHOULD have a greater impact on CFM than stack effect.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
