<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>We can and have to take account of infiltration reductions within
our UK building regulations calculations and indeed in certain circumstances
they can be the difference between different grades for the buildings when thermal
mass and other passive design techniques or super efficient HVAC systems have
been taken into account.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>At the design stage you “choose” an infiltration
rate that the design team is willing to take the risk on achieving and if not
you can use a default infiltration rate which equates to a reasonably well built
modern building (this obviously gets reviewed and reduced a little over time to
increase the requirements). The key to it being that in order for the
builder to obtain the building regulations and occupation certificates, the
actual measured air infiltration rates have to be put into the design simulation
model post build to ensure that what the design team has said will be achieved,
is actually achieved. In fact it is possibly at the moment one of the
most successful parts of our regulations.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>This has 2 main benefits, it means that contractors have to
think about the quality of their build and good detailing from the start and subsequently
if they allow a poor building to be built that exceeds the minimum standards or
their chosen design value, they have to go and identify the air leakage paths
and bring the building up to that standard before they can get an occupation
certificate.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>When you consider that our default air leakage rate is 10m3/hr and
we see many large commercial warehousing projects (a good example where
composite panels are often used for air tight seals) that have leakage rates of
less than 2m3/hr.m2 it is possible to see that large benefits might be possible
in some instances. On a large warehouse with perhaps background heating
for the operatives, this reduction in infiltration can result in very large
reductions in energy use/carbon emissions for heating, etc.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>I am slightly surprised that a USGBC/ASHRAE baseline rate doesn’t
exist to allow benefits to be taken into account, especially when it is
possible to use the test results to enforce improvements to be made, in a way it
acts as both carrot and stick.<o:p></o:p></span></p>

reduction in air leakage will not be considered, but that increases in thermal

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></p>

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></p>

color:black'>I see in Appendix G that: “G3.1.2.5. <b>Ventilation</b>.
Minimum <i>outdoor air</i> ventilation rates shall be the same for the <i>proposed</i>
and <i>baseline building designs</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></p>

style='font-size:10.0pt;font-family:"Arial","sans-serif";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><span lang=EN-US style='font-size:10.0pt;font-family:

Standard 90.1.”</span><span lang=EN-US> </span><span lang=EN-US
style='font-size:10.0pt;font-family:"Arial","sans-serif";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><span lang=EN-US><o:p></o:p></span></p>

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></p>
