La segmentazione e caratterizzazione del patrimonio costruito della Città di Carbonia per la realizzazione di un modello energetico urbano

The paper describes the results of the research project “Urban Abacus of Building Energy performances – Abaco Urbano Energetico degli Edifici (AUREE), funded by the 2019-21 Triennial Plan for the fulfilment of the Agreement between Ministry for Economic Development and Italian National Agency for New Technologies, Energy and Sustainable Economic Development (ENEA) – Project 1.5 “Technologies, techniques and materials for energy efficiency and energy saving in the electrical end uses of new and existing buildings”. The concept of AUREE project is a Web – GIS GeoBlog portal with customized interfaces aimed at sharing information on urban built environment and promoting the participation of local stakeholders to its improvement. The methodological approach is specifically addressed to small and medium urban centres, characterized by a low availability of basic data on buildings energy performance. The portal is implemented with a Uban Energy Model (UBEM) based on spatial Open Data, on a typological survey of the built heritage and a participative web framework. After an overview on the theoretical background the paper illustrates the general framework of AUREE project and focuses on the methodological approach adopted to for the creation of a typological abacus necessary for the energy model definition and its representation through the portal. The town of Carbonia is selected as a relevant case study. The application of the methodology on its heritage shows how an archetypification approach based on historical information provides a complete segmentation and classification of urban buildings. The results are transferred on the web portal that can represent the information on the buildings stock and facilitate the processes necessary to its improvement.
