Hello! Dr. Li,
The IDF run on our computer does not have any severe erros and very few warnings. I don't know why it has 5 severe erros on your computer. Jim's advice is very helpful and we will try to do that.
I am not quite sure what you meant by "do not use the IDFeditor". We set up the model using IDFeditor and copied some objects from the example file provided by E+. We then changed some objects based on our building. Are you saying we should not do this?
Thanks!

> Hi, Xing Your building entry still hve problems (5 severe errors). It is possible that the exported IDF text is not the same as the IDF in the third party software. You should follow the steps given by Jim Dirkes to display the variables and to trace the program operation. It is not possible to control five zones of a large building and hope to get the correct answer. You may ignore the basement, the EPlus simulation will not. I mentioned to you last time that, if you use templates in the IDF, do not use the IDFeditor to sort or change the expIDF and then send me the IDF. It is quite difficult to un-sort the groups and zones. The temperture control does not work for DesignDay simulation, because you have changed some schedules again.

> Dear All, We have an ASHRAE 90 system 8 baseline building. The E+ model appears to be correct but the "unmet hours" is a little too high. Cooling and heating unmet both exceed 200. According to ASHRAE 90, we should increase the system capacity incrementally until unmet (cooling + heating) is below 300. We changed the sizing factor in Sizing:Parameters but surprisingly found that it had very little effect on the unmet hours.
