In Europe, the 2020 Energy policy for reducing CO2 emissions by 20%, raising the share of renewable energy resources by 20% and improving by 20% EUs energy efficiency, aims not only to fight against Climate Change but also to reduce EU energy’s importation. The construction sector plays a big role in these targets; as buildings are long-lasting products, they represent an enormous impact in the consumption of resources, energy, and CO2 emissions. Thus, an Energy Efficiency (EE) policy was designed in order to control the energy performance in buildings. Despite actions were taken, and buildings were built with some EE criteria, the only way to reduce impacts was acting on existing buildings. A new sector was created: the Energy-Efficient Building Retrofitting. Are the businesses ready for the market? Are the new professionals ready for the sector? While the Energy policy was changing the construction sector, the training and education programmes related to this new field were still the same. The demands from the sector for skilled and qualified professionals in the energy efficient (ee) building retrofitting market have to be answered as the regulations and tendencies for reducing carbon dioxide emissions and energy savings are motivated by EU. nEBULA will provide added value to the students and professionals with higher education levels in the areas of building, construction and energy with the skills and competences to upfront in a professional matter projects related to Energy Efficient Retrofitting. The project starts with a capacity analysis applied to students and young professionals and a needs analysis applied to the building construction and energy companies’ representatives (future employers) a novel ICT tool, i.e a pilot mobile learning app, which is developed and tested throughout the lifetime of the project. During the project the target groups will be defined and reached via surveys and the small number of focus groups will be deeply analyzed both in country level and international level. The functional requirements of the nEBULA app, the most suitable methods for assessment to be included in and its platform will be defined. After the pilot testing of the app with the representatives of the target group, the nEBULA app will be available for education of students and young professionals and adapted to the interested higher education institutes’ curriculum. The project will be carried out by 6 partners from Turkey, Spain, Greece, The Netherlands and Belgium including universities, research institutions and SMEs. All partners have direct access, or are representatives of higher level educational institutions (universities & VET) in their countries, thus guaranteeing the realisation and reach of the target public. The main impact of nEBULA on (future) engineers, architects and technical experts dealing with retrofitting is to increase their awareness on ee and direct them towards design including the ee-concepts and regulations. By using the nEBULA app and through its networking they will be able to embed energy efficiency into their retrofitting designs, applications and/or related products and be able to access the guidelines and technical to-do tips during their professional life. Expected long-term benefits of the project are; adaptation of the mobile learning application to different higher education institutes’ curriculum, increased number of course materials and increased skills and competence of the students/young professionals related to ee retrofitting and entrepreneurship, to get accustomed to ICT tools as teaching materials.
