[EnergyPlus_Support] Re: A possible bug or I am doing somethinh wrong

Dear REZA,

I am not sure if the negative values have anything to do with the fact I created the file first in energy plus with relative coordenates and then I openned the file in openstudio and I did the geometric. when I created my zones, after I defined each surfice to what was connected to, this is why I put for example parttion wall connected to zone storage (example) What I should do to correct the problem? change the surface property for example change outside boundery (now set as "zone") for surface? 

Thanks and sorry to be a pain
