For many years now the importance of introducing energy space planning in communities has been emphasized with regard to the sustainable development of urban and municipal structures. However, little progress has been made concerning the transfer of the findings into practice. Actually, the topic is gaining momentum, not only in Switzerland, where there has been experience in dealing with so-called energy master plans for several years, but also in Austria. In the province of Salzburg, the topic of energyspace planning is fixed in so-called “spatial development concepts (Rämliche Energiekonzepte – REK’s)”, which are mandatory for municipalities. In Styria, the topic was introduced as a contribution to the local development concept (ÖEK); and in Vienna, the mandatory implementation of energy master plans was already decreed in eight districts in 2020. The new magazine „nachhaltige technologien“ presents success factors for this development in respect of the availability of special digital planning tools as well as the establishment of suitable framework conditions and process flows in public administration.
