For your situation, you should create an interzone ceiling/floor so that the heat transfer through the surface will work properly. Your 2nd floor boundary condition is neither "Ground" nor "Outdoors".

> Generally, the problem is when I set 'outside boundary condition' of roof and floor from 'surface' to 'outdoor' AC load of winter increases as expected. However,the AC load of summer decreases other than 'increase'. After all, while all set 'outdoor', AC load of winter is larger than that of summer. This is very wired. Can anybody explain for me? Or there is something wrong with my configuration. Thanks very much!
