Hello Daniel, The easiest way is to model the
ground using a ‘boundary’ with a constant temperature. The difficulty is in determining
the ground temperature. When the wall is thermally well
isolated, the ground temperature will roughly become equal to the annual average
ground temperature of the area (provided the wall is large enough for edge
effects to be negligible). When the wall is not thermally
isolated, the ground temperature will gradually increase, and after a couple of
years the ground temperature just below the wall will get close to the average
temperature of the zone.(again neglecting edge effects) The heat loss will
become less every year. Arie Van:
