The energy assessment should be carried out in a quick and simple way by the user of the tool. On the other hand it should consider all properties of the fa? ade influencing the overall energy demand in an adequately accurate manner. This task was solved by a methodological approach in two steps:

Step one is a detailed dynamical thermal simulation for the complete fa? ade variety of the morpholgical box, carried out as a preparatory work within the development of the assessment system. The results are stored by an EXCEL tool.

Step two allows the user of the assessment system to retrieve the energy data of any given fa? ade system via its definition in the morphological box respectively consideration the main six physical properties.
