Temperature problems

Hey all,

This is a pretty significant problem that I ran into and will have to supply the files I have been working with. So whoever thinks they can investigate this problem and help me out let me know and I can email the files to you.

Basically I have a finished OpenStudio model that was using autosize to size the equipment. That was all fine aside from me being able to investigate the temperature profile in the various zones of my building. I couldn't figure out how to do that aside from putting the autosize values into my .idf file and running it then. Which should be working fine. The problem is that I am getting crazy temperatures in zones that are related to one of my rooftop units. Like 33+C in zones where the cooling setpoint is 26.6 at maximum. I have went back and looked over the inputs I placed in the .idf file and everything looks good and there shouldn't be any problems. Also I am using a weather file that a colleague of mine created and this may be the problem but the zones being affected are only supplied by one AHU so the weather file format and information should be working correctly.

When I run my .idf file with an E+ weather file from the website there are no zones that go outside of the setpoints which makes me believe that the weather file I am wanting to use may be incorrect. That being said, above I also described that the weather file seems to be working correctly. I am stuck basically and can't figure out what the problem is.

If anyone is able to give me a hand let me know. I will send the .idf, .osm, and the two weather files I am using.

Thanks so much
