I think it's easiest to start with your second example when you move the wall out of the space. The program itself doesn't understand that the original space bounded by the floor, ceiling and 4 walls consisted of a volume. Therefore, when the wall is moved it doesn't understand that there is a hole. The wall is still in the program, it is still facing the same cardinal direction, it is still assigned by the same zone, and in both cases, it is not shaded by any other objects, so the program will model model conduction through the wall and solar gain through the windows. The program does not understand the hole.<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>When you delete the wall, the program no longer models conduction through the wall or solar gain through the windows. Basically, there is no longer a boundary there, although it's easier to think of it as an adiabatic boundary with no mass. This effect can be advantageous because if you need to create custom geometry in detailed mode and need to change the polygons, it can be difficult to get all walls to match exactly. Having a small gap or small hole is acceptable and doesn't lead the program to model natural ventilation. If you want to model natural ventilation, I believe you do this in detail mode under the "Internal Loads" tab.<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Your first example is the only one that should show a tiny amount of difference in the result - this is because I believe that the elevation of the building is accounted for in the calculation.
