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?
