<font size=2 face="sans-serif">Hello Faustine,</font>
<br>
<br><font size=2 face="sans-serif">thanks for your quick reply. So the
value asked by trnsys is the heat transmission resistance in hm²K/(kJ)
(in this case the unit is wrong in TRNBuild), right?</font>
<br>
<br><font size=2 face="sans-serif">I still have the problem that I would
like to add a factor of 0.05 W/(m²K) for the heat transmission resistance
for all surface areas. Does anyone have a solution how to implement that?</font>

Thermal bridges/Cold bridges in TRNBuild</font>
<br>
<hr noshade>
<br>
<br>
<br><font size=3>Hello Anne,</font>
<br><font size=3> </font>
<br><font size=3>To enter ur cold bridge here there is a solution :</font>
<br><font size=3>Create ur coldbridge in ur zone, the value asked by trnsys
for a coldbridge is in h.m.K / kJ is the value (1 / thermal
linear transmission). Basically in France u will find this value in the
thermal regelmentation. Then ur coldbridge is automatically created in
ur wall type manager.</font>
<br><font size=3> </font>
<br><font size=3>Then call, in the concerned zone, ur coldbridge and enter
the lenght corresponding to the coldbridge. For exemple for a vertical
coldbridge between two walls (consider the angle of two vertical walls),
it will correspond to the height of the walls...</font>

<br><font size=3 face="sans-serif">Dear Users,</font><font size=3> <br>
</font><font size=3 face="sans-serif"><br>
I know that this problem has been discussed before so I know that there
is a bug, but am not sure how to handle it:</font><font size=3> <br>
</font><font size=3 face="sans-serif"><br>
1. When you add a new massless layer with coldbridge effect you have to
enter the "resistancy" in hmK/(kJ). Do you actually have to enter
the resistancy, which would be in hm²K/(kJ) or does TRNBuild asks for the
conductivity, which would be in hmK/(kJ)?</font><font size=3> <br>
</font><font size=3 face="sans-serif"><br>
2. The layer type manager shows the same value for "resistancy"
as typed in before in hm²K/(kJ). It´s just a problem of showing the units
right, isn´t it? So is it actually the resistancy that is shown in both
cases?</font><font size=3> <br>
</font><font size=3 face="sans-serif"><br>
3. What is meant by the length? Is it the part where the walls connect
or is it the edge length? Independently of the entered value of the length,
the u-value doesn´t change. How does TRNBuild calculate with this value?</font><font size=3>
<br>
<br>
</font><font size=3 face="sans-serif"><br>
I would like to add a common used factor of 0,05 W/(m²K) for all surface
areas. How do I implement that?</font><font size=3> <br>
<br>
</font><font size=3 face="sans-serif"><br>
Thank you very much for you help in advance,</font><font size=3> <br>
</font><font size=3 face="sans-serif"><br>
