Energy Simualtion with Open Studio component using Airwalls for ceilings



Hello everyone!

I have looked the diretories and I wonder if you are still answering the doubts that come up from users, because all the discussions seens to be from 2016 rs.

I have an issue. I need to set the ceilings as airwalls, and I have done that through the solve adjacencies component. However, the simulation only works when I use the Run Energy Simualtion component. I am using conditioned zones as well, and I need to use the Open StudiO Component, but the ceilings as airwalls doesn’t work when I run the simulation with Open Studio. I really need help with that. Does anyone have the same problem? Any ideas how to fix this?

Hope anyone have an answer for that :slight_smile:


@iris_loche Please upload some images or documents about your issue.


Hello @minggangyin. Here’s my file:
When I use Energy Plus to simulate it works, but when I use Open Studio the airwalls doesn’t work.
I need to conditionate the zones and I need to use the Open Studio component.

Thanks for the reply :slight_smile:


@mostapha @chris I think it is a bug in the open studio component.
Please, help me. I really need this to work


@iris_loche ,

You are right that this was a situation that we were not catching, which we should be. I just pushed a fix that allows models to run when there are no floors for the zone and the loads are set to 0:

Thank you for reporting this bug.

As, @minggangyin was pointing out, having both the sample file and the component error message in your post are helpful for quickly identifying bugs like this.


Thank you very much for the quicly reply and for the help!
