<p class=MsoNormal>Hello all,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I am interested in modeling the energy savings that occurs
when windows are replaced with lower-infiltration alternatives. In the wizard
mode, the only place that I see infiltration is under the “Building
Envelope Constructions” Screen. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’m hoping someone can confirm my methodology:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Can I input a weighted average of window and wall air
infiltration here? If I’m looking at a building with 20% Window to Wall
Ratio, and the windows have 0.1 CFM/ft² while the walls have 0.04 CFM/ft²can I
apply an area weighted average into this box? I would take (20%*0.1+80%*0.04)
as the <i>façade </i>infiltration value.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>That way I could use the same formula to determine the area
weighted infiltration of the façade if better windows were installed.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>How do other people model this?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks in advance!<o:p></o:p></p>
