style="FONT-SIZE: 10pt; COLOR: black; FONT-FAMILY: 'Arial','sans-serif'">I told
them I wanted to use one of their building design templates and change only the
parameter for infiltration. We used an elementary school in Wisconsin with
a CMU back-up wall and brick cladding. TRANE showed me where the default
air leakage parameter for that building design template was located, and they
showed me how to change it to match the air leakage rate called out by the Air
Barrier Association of America. We ran the model before and after, and it
showed a 58% decrease in natural gas consumption and a 22% decrease in
electricity consumption. Right in line with the NIST study. They
confirmed to me that no matter what design was created for the model, a default
air leakage rate would be generated by the software.<o:p></o:p></SPAN></P>
