Hi, first off a simple question – when defining the thermal zone, what are the boundaries suppose to correspond to - the exterior facade or interior wall?
I have a house model situated on a sub terrain, meaning a "half-cellar" where the back wall is placed into a ground. How can I define a thermal zone so that the back-wall is set as a foundation? The side-walls are obviously half-exposed to air and the front wall as an exterior wall to the outside air. Any other suggestions how to simulate the energy loads of a sub terrain-level?
