This proposal entitled: "Energy upgrading and maintenance of buildings" refers to the education of students of 1st EPAL Lavrion to the specialties of Engineering, Electrology and Building projects. The program involves in principle theoretical training of scientific staff of the host organization, as well as scheduled visits to companies for internships and cultural visits. The training program was designed according to the characteristics and needs of the participants in order to obtain the specialized knowledge required in relation to the energy upgrading of buildings, so that in conjunction with the received practical skills and attitudes required by their specialty, to become competitive and be able to pursue and achieve their integration into the labor market. In the proposed project we expect to achieve multiplier effects and benefits, both to the participants and for the abroad actors involved. This gives added value to the proposal, contributing to the development of the European dimension in vocational training and vocational guidance and dissemination of the importance of mobility programs and transfer of European culture in the sending country. The training needs of students who are covered by the plan and which are directly related and relevant to the needs of the labor market focus on the upgrading of building facilities with the aim of improving the overall energy efficiency of buildings. The plan is expected to involve 20 students per stream, who for a period of two (2) weeks will go to Germany and Spain, February 2015 and October 2014 respectively. With the approval of the proposed project , our organization intends to organize a series of activities that will involve the preparation phase (publicity , collection requests to participate , a structured interview , selection of beneficiaries , seminar linguistic and cultural preparation , training guides, training materials , preparation of beneficiaries , organization and procedural travel and subsistence ) , the implementation phase ( going abroad , theoretical training, internships ) and phase after the end of training ( assessment , dissemination of results , administrative documents to the National Unit of the Erasmus +). By the end of the project, the trainees are expected to gain valuable experience and important skills and identified in the following results: * Checks and measurements for capturing energy demands * Techno-economic feasibility studies and energy consumption targets * Support in finding suitable financing * Installation of upgrade program * Provision of maintenance services * Monitoring and drafting energy reports. After the end of the main implementation activities of the mobility, for the proposed project, the expected impact for the participants will be to gain knowledge and skills for the subject they were trained, strengthening self-esteem, active participation in society and development of critical thinking, personal development and strengthening European citizenship. The project has an impact on partner organizations where participants carry information about the needs of local labor markets and the opportunity for networking and further exchange of experiences in similar bodies. Finally, the impact on the target groups is detected in the incentives created in the wider local community to participate in lifelong learning activities and exploiting opportunities to participate in educational activities to enhance knowledge and skills with participants and ensure professional experiences and personal development. The proposed mobility will generate significant long-term benefits both at the individual level and in the general developmental level, contributing to the added value of local and regional development, by investing in human capital, proven demand for energy upgrade of buildings due to the successful training of the participants and the elimination of disparities by promoting equal opportunities for men and women.
