<p class=MsoNormal>eQuesters:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Because eQuest assigns the exterior air film R-Value as a
function of orientation and wind speed, what is the best practice for
specifying the baseline model exterior above grade wall U-Value? It is my <i>assumption</i>
that 90.1 baseline 5.5 Tables includes an R-Value of 0.17 for the exterior
U-Value (See Appendix A3.3.1-General). Can anyone else confirm this assumption?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>To make a correct comparison of U-Values between the proposed
and baseline, it would seem to me that this air film R-value should be
subtracted from the 5.5 Tables baseline U-Value specification when input in
eQuest. Otherwise, there would be a double counting of air film R-Values in the
baseline calculation. Does anyone have insight into the USGBC perception of
this calculation methodology? I assume that USGBC might require proof that the
R-Value does not fall below 0.17. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Are there any prohibitions in 90.1 to simulating the
baseline building envelope without the thermal mass effects? For example, is it
permissible to specifying eQuest walls using the U-Value input in lieu of the
layers input? <o:p></o:p></p>
