Energy performance certificates analysis in Piedmont Region (IT). A new oil field never exploited has been discovered

Abstract

In recent years, the high energy consumptions and the excessive use of fossil fuels has led the European Community to adopt new policies aimed at reducing greenhouse gas emissions. In particular, the Energy Performance Certificates (EPCs) were introduced in the first European EPBD Directive in order to improve the level of energy efficiency of buildings reducing energy consumptions and relative emissions. In this work an analysis on the database of EPCs of residential buildings was performed. The objective of this work was to evaluate the type of retrofit action and the impact retrofit interventions for the Piedmont Region and for the city of Turin. The data used for this analysis were extracted from the EPC database of the Piedmont Region with 867,131 certificates in about 10 years. Geo-referencing of the EPCs it was also possible to correlate the energy performance of the buildings with other variables such as building and climate characteristics. The results of this work show that, through retrofit interventions 33-48% energy savings can be achieved. Moreover, there is still a high potential because the 33-48% of energy savings affects less than 6% of the total certified buildings, which are about 50% of the total buildings
