Now, I'd like to force steady oustide conditions, so that I can make a first analyze of my building.<br>My question is : how can I do that ? It seems that the building model impose that I use a weather file. So I see 2 options : 1) I create a "steady" weather file that I then use in my project, but this doesn't seem that easy to do (or does such a weather file already exist ? I didn't find one..), or 2) I try to modify my project so that my building receives steady conditions instead of time varying conditions from the weather file. I tried to do that, and I could almost do it. I used "equations" modules to impose constant conditions for TAMB, TGROUND, and so on.. it works. But then, when I monitor the temperature in a room, it is not completely flat. I don't understand why, because there is no gain/heating in any room, and all inputs to the building are constant, except for "AZEN" which is related to solar position. This parameter, I can't impose constant because TRNSYS tells me it HAS to be connected to the weather file.. So, that's the only thing actually varying, so I guess this is the reason why I don't get steady temperature in my monitored room.<br><br>In other words : how can I "disconnect" solar calculations from my project ?<br>Or even a more generic question : how can I impose steady outside conditions on my building, knowing that I created my project from a 3D building from Google Sketchup... ?<br>I mean, it seems to me like a quite simple problem, but the solution seems quite complicated...<br><br>Thank you for your help,<br><br>Arnaud.<o:p></o:p></p></div></body></html>
