<p class=MsoNormal>Dear all,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><span lang=EN-US>I need your help.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>I have simulated with TRNSYS a small quadratic
office building.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>One of my Outputs in TRNSYS is the heat
demand (Qheat).<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Can someone explain me, how TRNSYS
calculate the heat demand (Qheat) ?<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>If I calculate the heat demand with a “static
calculation tool” or per hand, then I have a difference of 40 percent to
the dynamic result of TRNSYS.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Are only the dynamic effects (e.g. storage
capacity) the reasons? And are 40 - 60 percent realistic<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Thank you for your answers.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
