<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">Further to Jakob’s reply, I have done some experiments on a real building to determine the relationship between infiltration rate and wind speed. I found for this particular
building a very linear relationship between the two variables. I performed a gas tracer decay experiment to calculate the infiltration rates at various wind speeds. Once you have an idea of the magnitude of infiltration rates for several wind speeds, you can
use wind speed as an input to the infiltration in TRNBuild using your derived linear coefficients. And similarly for the convective heat transfer rates on the external walls.<o:p></o:p></span></p>
