Abstract

[automatically translated] Public Administrations are constantly engaged to evaluate the feasibility of interventions of energy retrofitting of existing buildings sector, in order to achieve the energy efficiency targets set by European directives. As known, the building industry is a high potential field in this direction. This potential, however, can only be verified from a knowledge of the actual energy consumption of existing buildings, which is not always easy because the demand for energy, and its energy consumption, depend on difficult to standardize factors. In order to highlight the possible differences between assessments of standardized energy consumption and real consumption, We were carried out an experimental study on a sample of 25 buildings of the Sicilian Region with different characteristics from the geometric point of view, construction and plant engineering. The estimate of energy consumption for heating and hot water was carried out through the application of technology UNI TS legislation 11300: 2008, while real energy consumption have been deducted from energy bills. It 'was also proposed a possible categorization of existing buildings on the basis of energy consumption and of geometrical and architectural characteristics, in order to identify the analytical parameters that can be of reference to make the energy savings assessments in a large scale. The estimate of energy consumption for heating and hot water was carried out through the application of technical rules UNI TS 11300: 2008, while real energy consumption have been deducted from energy bills. It 'was also proposed a possible categorization of existing buildings on the basis of energy consumption and of geometrical and architectural characteristics, in order to identify the analytical parameters that can be of reference to make energy savings in large scale assessments.
