BUILD UP Skills UPSWING aims at developing three large scale fully functional training and qualification schemes for 3 professions with substantiated great impact on the energy upgrade of buildings in Greece. Initially, the specific training schemes will be designed according to the identified needs. The relevant occupational profiles will be updated and validated. Next, the training materials and guidelines, and the assessment criteria and tools for the exams leading to certification will be developed, while the “train the trainers” courses will be designed and piloted. Then, the schemes will be tested in pilot courses, to be evaluated and revised before launching to a fully functional large-scale level. In order to ensure the sustainability and enhancement of the training schemes after the project’s end, a number of accompanying measures in support of their coordination and operation are planned.
