All over Europe building operators are forced to reduce operating costs and to reduce CO2 emissions of a building. In order to reach these central objectives the central when operating buildings a building must be seen as a complex technical system; it needs a systemic approach where all aspects from building to operating must be considered. A resulting field of activity is the Building Service Engineering (BSE) that is of growing importance in Europe although there have been just a few training and further education facilities in BSE explicitly based on the systemic approach so far. Therefore new qualification demands have to be fulfilled by the employees. The project is targeted at the empirical recording of these specific demands and to describe them competence-oriented. By this means the future job training and further education structures are supposed to be coordinated in a better way with the demands of the job market. Furthermore, the transfer of acquired competences should be promoted among the different European countries and the cooperation between the world of work and the VET-system will be intensified. Each trainee in the occupational filed of GST should be enabled to do parts of his job training in a different European country and it should be possible to acknowledge all acquired skills and competences as part of his training frameworks. Since BSE combines and reinforces qualifications of different existing jobs that require training on the basis of its systemic approach, there is a need to make acquired competences transparent and easy to describe for new vocational training profiles within the BSE. Thus the model of the Vocational Qualification Transfer System (VQTS) is transferred to the field of BSE. Job-related competences are described in learning units, already existing training profiles in Europe are made transparent. Each trainee in the occupational filed of BSE should be enabled to do parts of his job training in a different European country and it should be possible to acknowledge all acquired skills and competences as part of his training frameworks.
