Hello all,
I am trying to build a building surface by surface. Using points as reference to create these surfaces. Somehow I get the below error:
1. Input _faces do not form a closed volume.
Room volume must be closed to access most honeybee features.
Preview the output Room to see the holes in your model.
But when I use the same points and instead of surfaces I create volumes and use the Create HB Room from Geometry, I don’t get any error message.
The final model is exactly the same. But the Surface by Surface component gives back an error, even though I know my model is a close volume.
Any solutions?

Thanks.
Hi @Barbarur,
For generating rooms by faces you will need to organise all faces which enclose the room into one list. So the input for creating 4 rooms should be a tree containing 4 lists. Otherwise honeybee does not understand which faces belong to one room.
Another issue regarding your model is that rooms with a hole in it are not accepted by energyplus. You should split the room into multiple rooms.

Understood. Thank you @Erikbeeren
Hi all,
I have a comparable issue, see the image. Should I divide this kind of geometry into two objects?
edit:
So I found the solution.
The problem:
The exterior walls and the extruded walls (from the HB Add Subface) where both added to the _faces of the HB Room. This created an error because of the double walls.
Solution
Only use the hb_obj of the HB Add subface in the HB Room component. 
, it automatically uses windows + doors + walls, so do not add the walls double in the _faces.HB Room component.

Hi all,
I face the same problem every time my facade opening is more than 0%, but if the facade opening 0% this warning did not show up. Could you guys help me with this warning? Hereby I am attaching my file.

I would start a new topic for this. This topic is fairly old and is marked as solved!
