<DIV>Hello, </DIV>
<DIV> </DIV>
<DIV>According to TRNsys my building file (.bui) doesn't work because it have got "a error in automatic heat transfert calculation for surface 1 or its adjacent surface : automatic heat transfert calculation is only allowed on surfaces within a zone".</DIV>
<DIV>I tried to exchange the orientation of the surface, no effect, the same error msg.</DIV>
<DIV>And I don't understand the last sentence because a surface is always descripted in a zone.</DIV>
<DIV> </DIV>
<DIV>If somebody met this error and solved it, can I have a replay, please.</DIV>
<DIV> </DIV>
<DIV>Elodie</DIV><p>
