-In the case of a specific building the position of the interior wall is known. The Ψ-value can then be calculated based on the same method as in the [[basics:building_physics_-_basics:heat_transfer: what_defines_thermal_bridge_free_design:thermal_bridge_calculation:Examples:EWFS|section on  "Exterior wall on floor slab"]]. For this, first a conductance without taking the interior wall into account is determined and then the conductance with the interior wall taken into account at the corresponding point. However, this requires a three-dimensional calculation which will be too time-consuming in most cases.

However, this requires a three-dimensional calculation which will be too time-consuming in most cases.
 As a two-dimensional approximation, which is also used in the context of certification for a construction system, it is recommended that the ground is taken into account and the distance of the interior wall from the floor slab edge assumed to be 1.5 metres. This procedure is demonstrated below using an example.
