Abstract: Energy efficiency in buildings has become a key goal of any energy policy. Europe relies on the Energy Performance of Buildings Directive (EPBD), which has been converted by Flanders into the ‘Energy
Performance and Interior Climate’ (EPB). Taking into account this Flemish EPB-standard (in terms of
maximum U-values, E-level and K-value), this study seeks the economically most profitable combination
of insulation - facade, roof, floor and glazing - for the Flemish citizen. For this purpose, a scenario-analysis is conducted using the EPB-software Flanders and a self-designed Excel file. Based on some
important profitability criteria, the most profitable combination is determined for three representative
types of dwellings studied. The scenario-analysis generates some well-founded guidelines for the
Flemish citizen when building a house. It shows that in order to ensure the maximum profitability from
investment in insulation, the key factor for the semi-detached dwelling is the insulation of roof and floor,
whereas for a detached dwelling the key factor is the insulation of facade and floor. As a subsidiary
consideration, the study also indicates that the U-values resulting from the more stringent E-level are still
not sufficiently stringent because the U-values obtained for the most profitable combination are far
below their maximum value. The same consideration applies in the case of the K-value.
