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.
Surface by Surface Model.gh (29.2 KB)
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
I have a comparable issue, see the image. Should I divide this kind of geometry into two objects?
So I found the solution.
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.
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.
