In recent years, the energy problem on the planet has become more and more intense, as the demands for energy consumption are constantly increasing. It has been found that the greatest burden, in terms of the environment, comes from the building sector. The need to reduce the environmental impact has led to measures to improve the situation through a regulatory framework focusing on the energy design of buildings. The purpose of this dissertation is to study the energy behavior and performance of an existing structure as a case study to improve its energy efficiency. The building examined in this thesis is a typical building, maisonette , house, located in the area of Halkidiki and specifically in Nea Iraklia (climate zone C '). First we present some general information regarding the building energy as well as the passive systems. Then a detailed presentation is made for the energy upgrade that we will do in the existing building. Finally we will draw a conclusion and make a comparison of the energy upgrade efficiency of the old house with the new.
