So if we model the base case with 2L/s.m2 per window area, then we can set the infiltration rate as 1 L/s.m2 per exterior wall area in the base case. Is this method applicalbe?</FONT></div> <div><FONT face="Comic Sans MS" color=#000080></FONT> </div> <div><FONT face="Comic Sans MS" color=#000080>Regards,</FONT></div> <div><FONT face="Comic Sans MS"

As we simulate the base case building energy use, we try to find out what is the reference infiltration rate setup up by ASHRAE 90.1-2004. However, we only find in section 5.4.3.2 (page 180) value is "2.0 L/s.m2 for other products". When we use e-QUEST to simulate the building energy use, we found that the default infiltration rate is set as 0.038 CFM/ft2 for exterior wall area, which is about 0.2 L/s.m2 per exterior wall area.<o:p></o:p></SPAN></FONT></div></DIV> <DIV> <div class=MsoNormal style="MARGIN-LEFT: 0.5in"><FONT face="Times New Roman" size=3><SPAN style="FONT-SIZE: 12pt"> <o:p></o:p></SPAN></FONT></div></DIV> <DIV> <div class=MsoNormal style="MARGIN-LEFT: 0.5in"><FONT
