The TMH has a strongly simplified geometry. In our problem each thermal zone describes one half of the TMH, which has in total an inner dimension
of 1.0 m x 0.5 m x 0.5 m. So each opaque construction element (walls, bottoms and ceilings) has a height of 0.5 m and a width of 0.5 m.
Double-click on each component and fill in these values in the *General tab* in the *Geometry* group.

Both thermal zones have an air volume of 0.5 m x 0.5 m x 0.5 m = 0.125 m3. The height of the zone is 0.5 m.
Fill in these values into the zone model's *zone1* and *zone2*.

Each of the windows of the THM has a width of 0.378 m and a height of 0.33 m, which leads to a window area of approx. 0.125 m2.
Each of the windows of the TMH has a width of 0.378 m and a height of 0.33 m, which leads to a window area of approx. 0.125 m2.
The thickness of the window pane is 0.003 m. Assign these three values to both window models.

Because *window1* is enclosed in *wall6* and *window2* in *wall5* the area of the window models has to be communicated from the window to the wall models.
