In the norms DIN EN ISO 13370 and DIN EN ISO 10211, only one Ψ-value is determined for a heated basement. This includes the upper connection of the basement ceiling and the connection of the basement wall to the basement floor slab.

In practice, pre-prepared Excel templates are used here also for determining the Ψ-values. The heat flows and necessary lengths can be entered here and the desired Ψ-value is received as the result directly: | In practice, pre-prepared Excel templates are used here also for determining the Ψ-values.

Note: this is not a thermal bridge free connection. In the example given here it is relatively clear that the basement wall connection to the basement floor slab has not been implemented in an ideal manner. | Note: this is not a thermal bridge free connection.
