I agree with you that the design of specially large buildings may require special considerations for simulation.
For heat balance calculation, the walls are considered as uniform and in one piece. Therefore, there is no additional information to take care of the room air model.
I have tried splitting the external wall into three horizontal pieces, top, windows, and bottom.
The exterior termperature values are different. However, the average or mean value of the three number were still about the same as the one value case. The difference is larger when the top portion is in the shaddow. I was thinking of splitting the internal zone into three sections to match. I did not do it because it would be similar to a low multi-storoey building. The top floor would be hotter, due to roof heating and ground cooling.
For an atrium where the walls are all internal, the position (height) of the thermostat in the room model should be chosen with care. It will be interesting to measure the temperature gradient of a real building. The skylight would be hot, and the ground floor would be cool.

In theatre or building for sports activity, there are always some zones whose internal height is much bigger than conventional zone.
What is the energy simulation strategy for these kinds of spaces? Does the well-mix still work?
Hope to get your advices.
Thanks very much
