Cultural Heritage has moved into focus of the European Union as engine for employment, economic drive and development. According to the report of the Horizon 2020 Expert Group on Cultural Heritage “Cultural heritage must be seen as a special, but integral, component in the production of European GDP and innovation, […]”. To guarantee longevity & usability of European heritage it is inevitable to look at all options. The role of Cultural Heritage for climate protection and the climate impact on Cultural Heritage are also in the focus of the OMC report “Strengthening Cultural Heritage Resilience for Climate Change”. Ensuring and increasing biodiversity will also be a major task for Cultural heritage site owners/managers. The INTERREG project “Cities. Gardens. Diversity” is working on reducing heat hotspots in historic sites, like the Imperial Palace Vienna district by identifying appropriate measures to reduce the solar entry and increase the biodiversity in the district. All these experiences will be integrated into a Vocational Education and Training programme which will be developed by Burghauptmannschaft Oesterreich (BHOe), who is responsible for the district. These course modules will be integrated in the training offers by The European Heritage Academy (EHA), which was established in 2017, and are accessible online and in person. All further education offers by EHA provide certification by ECQA, participants can obtain their certificate through validation of prior learning, eLearning and participation in course modules before passing an exam.
