The present study aims to highlight the energy efficiency of the type of constructions named as "Passive Houses", comparing the energy efficiency of a house built in a conventional way with a house built according to the regulations imposed by the Passive House Institute, having as a reference a classic passive house and a premium passive house. In the first part, the article presents generalities about what a passive house is and how it is built, what criteria should be followed and how such a project is certified, at the same time it is presented how a residential building is built, in a conventional manner, according to the legislation in force. In the second part of the article, different systems and components that make up a passive house are shown, how they manage to increase the energy efficiency of a house compared to a conventionally built house, at the same time managing to reduce the carbon footprint and reducing the monthly bills for energy. In the last part of the article, using graphs and tables, it is shown how the energy efficiency of a house is directly influenced by the chosen systems and their quality, how by respecting the criteria imposed by the Passive House Institute one can obtain a total or only partial improvement in the life quality of the living space, energy independence and at the same time a significant reduction in monthly energy payments.
