Buildings’ performance simulations for urban scale energy demand modelling in the Interreg projects Idee and Ueb

The paper describes methods and resultsof aprocedure for estimatingthe energy demand of urban areas by calculating energy performace of each individualbuildings usinga bottom-up approach. The procedure was developed in the framework of the European transnational project IDEE funded by the Interreg IV Italy-Austria programme. The devised methodology usesGIS procedureto analyze the characteristics of the building stock and aseries of parametric dynamic energy simulations to calculate the energy demand of individual buildings. Results are compared with the outcomes of aprevious research project that used the same city as case study.
