Abstract:
Recently the concept of energy efficiency in buildings is a topic of great interest due to several factors, including the expensive costs of energy and environmental issues related to pollutants emissions. Nowadays, energy efficiency and passive system are appraised for improving the environment. In this work will be conducted a comparative study on the energetic efficiency of various building typologies involving assessments on important factors like active building envelope technologies and the models of heat transfers via the thermal bridges. Throughout this research, a comparative analysis will be conducted not only on direct measurements using several forms of sensors in the selected buildings, but also several mathematical models for evaluating the heat transfer within a building, among which we inspect multidimensional analysis.
These evaluations will stress the importance of understanding the impact of passive systems applied in these house typologies that we are going to study. In this study, there are three post-communism residential buildings, built in recent decades using different construction technologies. These residential buildings will be a villa massively affected by the 2019 earthquake and reconstructed later, an old villa with an extension added in the recent years and a brand-new villa which is still under construction. The study will comprise these building typologies' energy efficiency in various seasons, thus estimating both heating and cooling energy efficiency.
