2015-02-11 11:59:47 -0500 commented answer The space referenced by this surface does not exist.

I have problems in the simulations, E+ give the materials and assigment of this surfaces.

2015-02-11 09:39:09 -0500 asked a question The space referenced by this surface does not exist.

I am trying to reduce the size of my model. I have 15 stories so I am removing the similar stories and using the multiplication tool, but I've received the message: "The space referenced by this surface does not exist." I have searched this surfaces but I can't view it. Has someone fixed this problem?

Hi, Stephanie Egger, I still receive this error

hi Icing, have you fixed it?

2015-01-17 11:55:16 -0500 commented answer Openstudio Run Time

@Amir Roth. Yes, I have run my model in a laptop with E+ v8.2. The same file I send to the cloud.

2015-01-16 13:38:11 -0500 commented answer Openstudio Run Time

@Amir Roth, the E+ is the V8.1 (used with OS 1.5), but when I send the file, I change the version to V8.2 with the EnergyPlus Version Updater. I donĀ“t know if before to sent the IDF i have to change something in the file, please could you guide me how use correctly the cloud?

@Amir Roth, I am trying to use the Cloud, I have access to input my files, but I have not been able to run the simulation successfully. I always get the error:

Have you try to use the cloud? or do you have any procedure to use the IDF file generated for OS?

yes, it is autosized.

Hi!, thank for your answer. My model have 24 thermal zones, the building have 15 stories (HVAC=Chiller), and there are others spaces where the hvac equipment works independent, like cocktail lounge or auditorium.

The model have 1134 spaces, 9733 surfaces and 1009 subsurfaces. Referent to the shading surfaces, I am not considering it. Respect to the selected solar distribution option in the building object, the quantity of output, daylighting, thermal comfort models (KSU model is slow), could you share me some link for read how apply it en OS?

I have not been performing my project with Software Trainer, I've developed by trial and error, then when I did the model have been learning what works and what does not.

Now I make the necessary changes to my model resembles reality, but want to know the impact of changes, and that I should further adjust

Thanks, I already have used the OSM diagnostic, now I am setting my model to the real condition, because in my model I have different occupancy per story. I am running the simulation, for check if the energy consumption is approaching for the real.

thank you for your answer, but I am detailing each story because is my graduation project and I must include the information.

2014-11-20 08:59:09 -0500 asked a question Openstudio Run Time

I am developing a model of a large office building in Open Studio 1.4. It has 1000 spaces and 15 story. The problem is the run time. The simulation delays 7 - 9 hours. How can I fix it?
