Floor that is situated partly below the grade

I am modeling a two-storied building. It has one floor that is situated partly below the grade. Upper part of this floor lying above the grade and contains few windows. I have not found how to model this in eQUEST. I have tried to make 2 floors instead of the lower floor: one is below and other is above the earth surface, but then they have a ceiling between them! It is wrong, I think! I do not need this additional ceiling in the model.

Is there anybody who speak Russian here? :)

Sincerely yours,

Read DOE2.2 Volume, you can build that wall separately, some underground -
you can see it in eQuest 3D view, in green color, and some part is upground.
Just cut the wall and input the accurate coordinate in detail mode.

Hi Mikhail,

It is not a straight-forward process in eQuest but it can be done. If I
were in your shoes however I wouldn't separate these two constructions in
eQuest. I would do some pre-processing of my inputs on my own with a
pencil & calculator. My approach would be to calculate the area-weighted
average for my U-value of the wall based on the following:

(U-value underground const * X% of total wall area) + (U-value above-ground
const * 1-X% of total wall area) = Model Wall U-value for my simplified
input value.

Where you "manipulate" or process your input data outside of eQuest using
sound engineering & mathmatically theory you can simplify your input process
significantly. The challenge & balance to remember is that we have to be
careful not to over-simplify our input assumptions too much if they may skew
our model results in anyway. Just like life, good simulation skills are a
balancing act.

Also, my Father speaks Russian and if you need more detailed assistance with
your energy modeling & eQuest skills I could have him translate for me from
English to Russian if this would help you.

Pasha, Thanks for advice.
But probably there are any possibility to make "two rows of windows" floors? I mean, to do something look like atrium (one volume on few floors).

Pasha, thanks. I have found "atrium" checkbox.

But, now I have new questions about atrium.
If I have two floors shell (one above and one below grade) and "atrium" checkbox is switched on. Are my floors going to be merged in one volume and so I`ll fix my problem with floor that is situated partly below the grade?

Sincerely yours,

Thank you, Pasha!

I understood)

I wasn`t write right. I already have one shell with two floors (below & above grade). And I did as You written in first way.)

Sincerely yours,
