This presentation investigates the energy-saving potential and cost-effectiveness of energy efficiency measures in the residential sector in Europe. To provide answers to relevant research questions, the DREEM model was used to simulate the energy performance of buildings in 8 EU countries (Greece, Italy, Spain, Croatia, Romania, Latvia, France and Ireland). Nine energy efficiency measures were assessed in each building and a technoeconomic analysis followed to assess the cost-effectiveness of each measure.
The application aimed to identify retrofit measures that are not only beneficial for the environment but will also incentivise the owner of the buildings and will ensure effective private and public budget spending. According to the modelling results, the replacement of an old heating system with an energy-efficient heat pump system is among the most cost-effective measures for all countries, while it also illustrates high energy-saving potential.
