the maximum level for new windows of 0.3, then it doesn’t sound as high…
new windows must be 3x less leaky than old ones – that sounds like the
right reduction to me. <o:p></o:p></span></p>

A colleague converted this to leakage area in CFM/SF at 75 pa. His number was
1.4 CFM/SF based on the table (not sure which value he used). <o:p></o:p></span></p>

it as the infiltration for a whole wall, when in actuality it only applies to
the window? Assuming the wall has little infiltration, a 25% WWR would bring 1
CFM/SF (window) to around 0.25 CFM/SF (whole façade) – probably a little
higher if accounting for the wall leakage, but not significantly so. Does that
number still raise alarm bells? Not to me, but I don’t have as good a
feel for this as Carol does. <o:p></o:p></span></p>

percentage reduction without some more information. I believe that the
requirement to meet the DOE’s VPP for windows is a maximum infiltration
of 0.3 CFM/SF – this leads me to believe that some new windows have more
infiltration than this. My company manufacturers windows with infiltrations as
low as 0.01 CFM/SF. I’m having a hard time finding a source, but
I’m pretty sure I’ve heard of modeling existing windows with
infiltration as high as 1 CFM/SF. A building with a large WWR and very leaky
windows could substantially reduce whole-building infiltration values.</span><o:p></o:p></p>

eQUEST changed the infiltration between the two cases you would be able to see
the change in your .inp deck. I'm not sure what the impact of doing the change
using the EEM Wizard vs. simply copying and renaming your input deck and making
the change in it's own .inp deck would be. You could experiment and see if there's
a difference. If it doesn't change your infiltration I would lower the
perimeter infiltration rate conservatively by a fixed percent. You might Google
infiltration rates on line and find some information related to how much to
expect for a single pane window to a double pane window. Also, be sure to
account for your frames, too. Are they thermally broken? Does the frame
material change, etc.<br>

all,<o:p></o:p></p>

<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>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 style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'> <o:p></o:p></p>
<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>I’m
hoping someone can confirm my methodology:<o:p></o:p></p>
<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'> <o:p></o:p></p>
<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>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 style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'> <o:p></o:p></p>
<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>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>
