Trying to split up an existing larger zone into several thermal zones. I have a very large open area with several tstats everytime I try to split it into smaller zones surface and surface match it I have problems such as boundary conditions changing, white surfaces, etc. I split up the space copied it then created a new space and selected Paste In Place that works fine but when I try to match surfaces it does not like that.

Thank you in advance.

@Luna. Please tag this question with something. 'openstudio', 'multi-zone'. something. Thanks.

I'd recommend tagging with 'zoning' since 'multi-zone' can refer to specific types of HVAC equipment.

@Luna, is your question geared to a specific simulation tool, e.g. OpenStudio? I'm removing the tag for 'openstudio' and let you revise your question or add a tag yourself.

Here is a video that goes over this process, including surface matching. Since the video was made we added a user script that moves selected surfaces to a new space. If you do this with a subset of surfaces in a space it splits a space. If you do it with multiple spaces selected it merges them into one space. You still have to manually clean up shared surfaces. I never had time to go back and enhance the script for this. Still it should be useful.

I wasn't sure if there was a way to embed the video vs. linking to it?

@David Goldwasser Embedded video is not supported by UH at this time. The link will do fine for now.

Hi David I followed the video drawing another surface inside one space, but it didn't split my space. When I click the space it is still one space with another surface inside of it rather than two different spaces

@Brianna the video has you manually make a new space, and then pasting content in place into that space. So I don't know how a space didn't get made. If something went wrong you might have a new space without any surfaces in it, but I don't see how a space would not be made. How are you determining you don't have a space, is this based on E+ output? If that is the case make sure the new space is assigned to a thermal zone.

thank you for this detailed reply David !

I have the same problem with a project that I have, the solution that I find was to create the amount of spaces that I need to split the zone and then intersect them so i don't leave any vertex or surface on the air, finally match the entire model. I hope it works for you :) . In advance i apologize for my English.
