Abstract

The paper describes an analytical procedure which allows the characterization of the energy performance of new and existing buildings, in a large urban context, through Geographic Information Systems (GIS). The methodology tries to codify a new process of integrated urban planning, aimed at identifying and designing energy efficient new buildings and the refurbishment of existing ones, for sustainable urban development and growth. The multidisciplinary of various boundary conditions, within an incomplete/unapplied legislative framework about building energy efficiency, makes a very interesting scientific study regarding the sustainability of town planning and urban retrofit, guaranteeing: environmental stewardship and economic development targets; global goals of an environmental sustainability; introduction of procedures for a global view of the construction process that has to be declined in each local context for focused territorial planning. Therefore, the paper suggests a geo-referenced model, through which it will be possible to determine the energy consumption of each building and then to support the management of territorial transformations. The new methodological approach has been applied to the historical center of Benevento. With reference to each building, the energy demand was determined by crossing census data, (ISTAT/ENEA) and the results of predictive physical correlations, with thermo-physical properties, cooling/heating needs and energy requests. The achieved results and their reliability allowed us to obtain \“urbanenergy maps” (MEU), which represent an important tool for advanced energy planning, in terms of both territorial control and evaluation of the energy retrofit potential. Keywords: inner city, energy audit, energy retrofit, GIS, sustainable urban development.
