It is not clear what weather data is used in that test. My friend said, it is TRY for Wuerzburg (weather region 5). I built the model and used this weather data, but the results are different. Same trend but not close (see VDI6020.jpg). My question is: is that the correct weather data for VDI 6020 test? if yes, why is so much different between VDI's results and ESP-r's results? I have checked construction and schedule of my model are according to VDI 6020 (Example 1). Thank you for your help.<br><br>regards<br>Adhi<br></div>  </div><br> <p class="MsoNormal"> </p> <tbody><tr> <td style="padding: 0.75pt;"> <div class="MsoNormal" style="text-align: center;" align="center"><font face="Times New Roman" size="3"><span style="font-size: 12pt;"> <hr align="center" size="1" width="100%"> </span></font></div> <p class="MsoNormal"><font face="Times New Roman" size="3"><span style="font-size: 12pt;"><img id="_x0000_i1026" src="http://us.i1.yimg.com/us.yimg.com/i/ca/iotg_search.jpg" align="absbottom" border="0" height="25" hspace="4" width="25"><a href="http://ca.toolbar.yahoo.com/" target="_new"><b><span style="font-weight: bold;" lang="NO-BOK">Yahoo!
