Abstract:
A European directive that came into force in December 2020 requires all new buildings to reduce energy consumption. In recent years, the Romanians have begun to develop an interest in passive houses, because this type of house is much healthier and the maintenance costs are even 10 times lower compared to a conventional house.
This paper presents a comparison between the performance of a passive house and a traditional house. A passive house leaves a low carbon footprint because it uses non-polluting materials. Moreover, it can maintain an almost constant temperature throughout the year due to its very good insulation and active ventilation, so lower energy consumption. Although the cost of building such a house is about 10% higher than that of the traditional house, living in a passive house is significantly cheaper in the long term.
On the other hand, in a traditional house a significant amount of energy is lost during the heating process. Heat is lost through walls, windows, roofs, floors, and this happens because this type of house is not compact; it does not have very dense insulation and good ventilation. A further case study of the energy consumption to heat and ventilate a passive house using renewable energy sources will be done.
