to demonstrate or document air leakage rates after construction. So that
is typically leaving us with two variables in a model that are based on the

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>

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 lang=EN-GB 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 lang=EN-GB 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>

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
mass energy-savings from using concrete walls or energy benefits from using
wooden studs will be used to compute building energy performance. This
obviously rewards concrete block producers and wood stud suppliers and
penalizes air barrier suppliers. <o:p></o:p></span></p>

establish a base line condition for air leakage so no savings can be

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>

<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif";
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'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif";
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>

<p class=MsoNormal style='text-autospace:none'><span 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
style='font-size:10.0pt;font-family:"Arial","sans-serif"'>Offers information on
the intent and application of Standard 90.1.”</span> <span
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><o:p></o:p></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>
