The EvEnEf project supported the development of innovative and competitive professional approaches in the field of energy efficiency in the building sector. As most of actors in the realization of buildings are SMEs, the training of entrepreneurs and managers is a major issue to meet the target of the Energy Performance of Buildings European Directive. The different national building thermal regulations are more and more innovative and demanding, but the professionals who are in charge of the realization of buildings are not well informed or trained. Even if some of these professionals are aware of the challenge concerning the energy efficiency and can be considered as leaders in this sector, the training is not always a priority for the majority of them because of economical constraints. A significant effort remains to be done concerning the attractiveness and the accessibility of continuing training modules in the building sector. In this context this project adapted and integrated innovative training courses to improve energy efficiency in buildings alleviating the lack of knowledge of entrepreneurs and managers of the building industry. The project brought together VET providers, higher education institutions, SMEs, chamber of crafts in the sector to assess future skills needs and promote business input into course design and delivery, as stated in the "New Skills for New Jobs" initiative and to adapt/develop special modules in the energy efficiency of buildings and its evaluation for upgrading knowledge in the sectors of construction, energy supply and water supply. Through job analysis the necessary knowledge, skills and competences in thermal insulation and air-tightness, innovative and efficient systems for heating ventilation and cooling, thermal comfort, and the evaluation of the performance of all these technological solutions, were specified, developed and tested during this project. The transferred pedagogical content was adapted, upgraded and implemented on an e-learning platform. The project helped to improve the competitiveness of SMEs of the construction sector and to improve the employability of the professionals on a European scale. This objective has been met by helping professionals through vocational training to improve the quality of their work according to the new standards in the different European countries concerning the energy efficiency.
