<p>Elise,</p>
<p> There are a lot of things that could cause this behavior. If the
building is sitting on the ground, the most likely problem is that
the ground temperature under the building is (incorrectly) set to
0C. In any case I cannot think of a physical reason why this would
happen so my guess is that there is an incorrect assumption or
connection. If you aren't able to find the cause then perhaps your
Trnsys distributor can assist.</p>
<p>kind regards,</p>
<p> David</p>
