Use of Energy Performance Certificates data repositories in Urban Building Energy Models

The development of building stock energy models still suffers from the lack of information about the existing building stocks. The article is focused on the creation of an Urban Building Energy Model (UBEM) from accessible information sources, accompanied by input data from the Energy Performance Certificates (EPCs). Guidelines addressed to future developers, regarding the establishment of an urban-scale energy model in case of data lacking, are provided. This methodological approach was applied to an urban block in Northern Italy. Once the virtual environment had been defined on the UMI software, the energy performance for space heating (EPH;nren) was assessed and compared to that derived from the EPCs. Despite different calculation methods are compared, an acceptable deviation (10%) occurs for the residential building units.
