Świadectwo charakterystyki energetycznej budynku jako instrument prawa zapewniający energooszczędność budynków - analiza zmian w prawie polskim

The subject of the article is an attempt to assess the level of implementation of European Union law into the Polish legal system in the field of the functioning of the energy performance certificate for buildings, which assesses the energy consumption of a building, its parts or investment. Thanks to this, it shows the need to introduce changes in order to reduce the energy consumption of the building. An energy certificate is prepared by an authorized person. Buildings with lower energy consumption, that are heated using modern technologies and renewable energy sources, are becoming more attractive in economic terms. In addition, they implement the objectives of the provisions of EU directives that provide for the strategy of environmental protection and the reduction of greenhouse gas emissions by humans.
