I am re-phrasing my question:<br><br><pre><i> </i>
</pre><p class="MsoNormal" style="margin-bottom: 0.0001pt; line-height: normal;"><i><span style="font-size: 10pt;">In "Building Envelope
Constructions" window (3 of 25) I put an Overall R-Value of 30
h-ft2-°F/Btu...</span></i></p>
<p class="MsoNormal" style="margin-bottom: 0.0001pt; line-height: normal;"><i><span style="font-size: 10pt;">But, when I go into the .inp file in
the roof construction details, I see a U Value of 30 Btu/h-ft2-°F!?</span></i></p>
<p class="MsoNormal" style="margin-bottom: 0.0001pt; line-height: normal;"><i><span style="font-size: 10pt;">It is not the same thing!</span></i></p>
<p class="MsoNormal" style="margin-bottom: 0.0001pt; line-height: normal;"><i><span style="font-size: 10pt;"> </span></i></p>
<p class="MsoNormal" style="margin-bottom: 0.0001pt; line-height: normal;"><i><span style="font-size: 10pt;">Does it mean I enter the U value
though eQuest is asking for R-value (DD wizard). </span></i></p>
<p class="MsoNormal" style="margin-bottom: 0.0001pt; line-height: normal;"><i><span style="font-size: 10pt;">Why is eQuest not converting the
R-value entered to U-value.</span></i></p>

<p class="MsoNormal"><span style="font-size: 11pt; color: rgb(31, 73, 125);">U-value is the inverse of R value. A U-30 is the equivalent of
R-0.03. Likewise, if you have an R-30 roof, you would have a U-(1/30) =
U-0.03. Is it possible you entered in R-value where you were meant to enter U?
I would check, and maybe try to change what you’ve entered.</span></p>

<p class="MsoNormal"> </p>
<p class="MsoNormal">Hello All -<br>
<br>
I don't know whether I am understanding the R value input in eQuest in the way
its supposed to be.<br>
<br>
In the Building Envelope Constructions <b>(3-25) in the DD Wizard:</b><br>
<br>
Construction: Custom, layer by layer construction<br>
<br>
Layer-by layer: Arena Roof (name of the roof I have created)<br>
<br>
In the layer by layer window I use the 'Specify Resistance' (under the spec
method) option and insert the overall R value of the roof directly below in the
box. <br>
<br>
When I go to the.inp file, I see the following -<br>
<br>
"EL1 Roof Construction" = CONSTRUCTION<br>
TYPE =
U-VALUE<br>
U-VALUE = 30<br>
ABSORPTANCE = 0.6<br>
ROUGHNESS = 1<br>
<br>
It says the U -value is 30 which is really low. Am I missing something here in
understanding the U-value and R value. (I have inserted the r value as 30 not
the U value)<br>
<br>
Thank you for your comments in advance.<br>
