has nothing to do with actual infiltration in a constructed building. How much
infiltration results in an actual building is 99.9% construction and 0.1%
design and specification. A well design building to minimize infiltration,
with poor attention to details during construction and sloppy workmanship can
end up having more infiltration than an average design with a good construction
team. <o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color=black face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:black'>The National Institute of Standards and
Technology (NIST) did an extensive study documenting a greater than 40% natural
gas savings and a greater than 25% electricity savings across the nation for
building energy consumption if buildings were uniformly constructed with air
barrier systems installed. They evaluated 116 existing buildings and computer
modeled several different building types. The purpose of their study was
to provide information to ASHRAE concerning whether it would be desirable to
add an air barrier requirement to ASHRAE 90.1.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=black face=Arial><span style='font-size:

<p class=MsoNormal><font size=2 color=black face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:black'>As a result, I’ve always thought that
Appendix G to ASHRAE 90.1 allows you to change the air leakage rate off the
default and onto a rate corresponding to an air barrier installation, so that
you could claim LEED points for the corresponding energy savings.
However, an architect at a presentation I did said you could not do that under
the LEED and ASHRAE requirements. (I know the models will do it, because
I’ve done it on the TRANE model and obtained results that support the NIST
findings.)<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color=black face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:black'>I see in Appendix G that:
“G3.1.2.5. <b><span style='font-weight:bold'>Ventilation</span></b>.
Minimum <i><span style='font-style:italic'>outdoor air</span></i>
ventilation rates shall be the same for the <i><span style='font-style:italic'>proposed</span></i>
and <i><span style='font-style:italic'>baseline building designs</span></i>.”
However, I searched the document for “outdoor air ventilation” and the phrase
occurs only in the context of mechanical systems that are designed to
intentionally bring air into the building. If this section is the basis
for concluding that air leakage barriers should be left out of the modeling,
then I have trouble understanding why.<o:p></o:p></span></font></p>

<p class=MsoNormal style='text-autospace:none'><font size=2 color=black
face=Arial><span style='font-size:10.0pt;font-family:Arial;color:black'>Appendix
G says that all components of the building are to be modeled as designed.
That would preclude modeling as if an air barrier system did not exist in the
design. It says the baseline building model is to have steel-framed
above-grade walls, and it is silent about the design building, but the User’s
Manual says that if the design building walls are block or cast concrete, then
“the mass is credited in the building performance rating method.”
Likewise, if the walls are wood stud instead of steel, then the Manual says
credit is given for the superior energy performance of wood frame versus steel
frame. The User’s Manual states that it: “</span></font><font

information on the intent and application of Standard 90.1.”</span></font>
<font size=2 color=black face=Arial><span style='font-size:10.0pt;font-family:
Arial;color:black'>Given these examples in the Manual based on existing thermal
mass energy-saving data and wood-versus-steel stud energy data, it is difficult
to conclude that a wall that is constructed with materials meeting the air
leakage limits and installation requirements of the Air Barrier Association of
America and determined to produce significant energy savings by the NIST study
based on those same limits and requirements should be modeled as if it leaked
air like a building without an air barrier. </span></font><o:p></o:p></p>

you know of any reason why it is not proper to change the air leakage rate
through the building envelope in the design model to show the benefit of air
barriers.<o:p></o:p></span></font></p>
