“…At present, in the European Union (EU), energy production and consumption are responsible for approximately 75% of the entire volume of greenhouse gases emissions. Out of all economic activities, the construction sector is responsible for almost 40% of the entire energy consumption registered at the EU level [4][5][6][7][8][9][10]. Moreover, upon analyzing all activities specific to this sector, the built environment is responsible for 36% of EU GHGs emissions [8,9,11,12].…”

The present state of the natural environment is significantly influenced by the construction sector. Due to the large amounts of consumed natural resources and materials as well as the high volume of emitted pollutants, the building industry is considered to have a key influence in achieving a global sustainable development. A considerable part of the ecological impact of the built environment is influenced by the energy consumed for creating appropriate indoor conditions as well as by the greenhouse gases that are emitted during the operation stage of a building’s life cycle. Therefore, the energy performances of existing buildings must be significantly improved in the near future. This paper analyzes the influence of the thermal insulation thickness of walls on the linear thermal transmittances and the heating demand of an existing building. The resulted values show that while increasing the insulation of the walls leads to a serious heat demand reduction, a deep renovation of the building cannot be achieved solely by using this solution.
