<p class="MsoNormal">The 0.038 cfm/ft2 is the Wizard Default. We typically override it to a higher value, but not to 0.4 cfm/sf. That’s at a pressure well above typical building pressurization. We’ve used 0.04 and 0.05 in the past with no questions asked. ASHRAE
90.1-2016 G3.1.1.4 has defined a method to determine the infiltration rate.<o:p></o:p></p>
