Users,</span></p>
<p class="ydp7ca4ff0aMsoNormal"><span lang="EN-US">I’m using
TRNSYS 16.</span></p>
<p class="ydp7ca4ff0aMsoNormal"><span lang="EN-US">I simulated
a building with the four type EXTERNAL walls facing respectively due Northeast,
Southeast, Southwest, Northwest. I notice in the file “T56_Std-Output.sum” that
“SOLAR_RAD” is equal to “zero”. I understand that it means no solar radiation
is received on external walls, which is impossible.</span></p>
<p class="ydp7ca4ff0aMsoNormal"><span lang="EN-US">Could you
please address this problem. How can I solve this?</span></p>
<p class="ydp7ca4ff0aMsoNormal"><span lang="EN-US"> </span></p>
<p class="ydp7ca4ff0aMsoNormal"><span lang="EN-US">Best
regards,</span></p>
