EPCs (Energy Performance Certificates) are important tools to identify the performance of the building. In many countries, it is compulsory to have EPCs while selling, renting, or constructing a building or a part of it. This research thesis under the shelter of the TIMEPAC project aims to broaden the array of the energy performance indicators within the Energy Performance Certificate. It aims to underscore a holistic approach to assessing the building’s overall performance. There are several Transversal Deployment Scenarios such as generation, storage, analysis, and exploitation that are included in the stages of EPC workflow. This research thesis aims to perform an energy audit in a residential building in Torino with possibilities to implement energy efficiency measures for the upgradation of energy classification in Energy Performance Certificates.
