Act No 555/2005 Coll. on Energy efficiency certification of buildings
The Act regulates energy performance certificates (EPC) for buildings. The legislative changes set standards for the compilation of EPCs in order to improve their quality. Different energy efficiency categories are designed to help both property owners and purchasers to classify the energetic status of the building, related expenditures for energy consumption and GHG emissions. Buildings that are obliged to provide an energy performance certificate as well as an energy efficiency label include public buildings with a total floor area of more than 250 m² used by a public authority and frequently visited by the public. Energy certification is required for buildings or separate parts of a building that are sold or rented to a new tenant, as well as all newly constructed buildings or all buildings that have undergone major renovation. The Act equally determines the circumstances under which the owners of building or the auditors can be fined.
