Abstract:

There is an increasing emphasis on raising the energy efficiency of housing, within the EU member states, but also at national level. Buildings are among the largest consumers of energy, so an increase in energy efficiency will lead to a reduction in energy bills, a very important issue in today's global context. In recent years, passive houses have begun to rise the interest of Romanians both in terms of health and reducing the cost of maintenance, even 10 times lower compared the conventional house. According to the Passive House Institute, the passive house is the house with high thermal comfort and minimum energy consumption. The annual energy consumption for heating such a building is around 15 kWh/m2 year. A passive house has a small environmental footprint, by using non-polluting materials. With denser insulation and active ventilation, an almost constant temperature can be maintained throughout the year. Although the cost of building such a house is higher than that of a traditional house, living in such a house is significantly cheaper. On the other hand, in a traditional house, a significant amount of energy is lost during heating. The heat is dissipated through walls, windows, roofs, floors, precisely because this type of house is not well sealed, does not have very good insulation and ventilation. This paper deals with energy performance, comparing the conventional house and the passive house, as well as upgrading the traditional house by using passive methods, essential for creating performance in order to reduce the need for energy and CO2 emissions.
