Energy Retrofit of a non-residential and historic building in Rome

The purpose of this manuscript is to analyze the interventions of energy retrofit of a non-residential and historic building, through a dynamic simulation by the use of the TRNsys code. The study is made up of some steps: • the analysis of the building and utility data, including study of the installed equipment and analysis of energy bills; • the survey of the real operating conditions; • the selection and the evaluation of energy saving measures; • the identification of interventions of energy retrofit; • TRNsys simulation of the effects of these interventions on energy behavior of the building. The paper aims to show the results of the study, to discuss the expected energy behaviour of the building and to comment on the options for introducing energy saving techniques
