The 2ISECAP project will maintain and enhance the functionalities and the content of the Database of Practice developed within INTENSSS-PA project (INTENSSS-PA 2018). The added value of the specific database is that further to an already meaningful content of research work and case-studies on ISEP it provides guidelines on how to implement participatory integrated energy-spatial planning, while its search engine provides a functionality that is based on a clustering of European regional areas, where a European municipality/city/region can find case studies and references that correspond to its socio-economic, environmental and morphological characteristics.
