Yard at underground level

[Powerenergie]

Hi there,

I've having a problem when modulating a building that have a yard attached to one facade of the building. The problem is that that facade and yard are at an underground level. So, when I go to the model viewer, the top of the room that is intended to be the yard is filled by the ground plane, althought I've set a hole at the top of that room.

How can I modulate this kind of situations?
Below are two images of the situation I'm dealing with.
Can anyone help me solve this problem?

Thank you very much.

Hi,

For visuals in modelviewer you can just switch off the Ground Plane so you can see the rooms below. Unfortunately having a hole against the groundplane won't cut a hole out of it (this should get improved in future but I can't say when).

What I've Seen in the past as an alternative to using the Ground Plane would be to model a ground surface and make it a shading object in ModelIT, this way you have more control over it.

Note for thermal simulations you shouldn't be modelling external holes like this but if it's only for lighting or visuals then it's no problem.

Hi to all,

I'm currently having the same problem but what i really want is to do thermal simulations in my model.

Can anyone help me?

Thanks in advance.

we don't model courtyards as thermal spaces, thermally VE is only interested in conditioned spaces. The answer is you don't model the courtyard, it is only defined by the rooms adjacent to it.

Just in addition to Phil's sensible advice "switch the ground plane off as it's only a visual thing"...

You want to set the external walls and the "ground" floor condition to be "temperature from profile" rather than "external air". This was you can assign a schedule profile to the surface to represent the ground condition.
Check google for what the temperature of the ground will be (2-6m depth is a good enough approx I think) in the country your model is based.
