Assessment of Thermal Insulation Properties of Envelope Structures of a Burgher House in Kosice

The article presents a basic overview of the most frequently used and proven interventions in historic buildings, focusing on the details of a burgher house in Kosice. In the case of renovation and reconstruction of an old building, it is necessary to take into account specific facts. A normal building is approached differently and a building that has historical value is different. The Energy Efficiency Act exempts historic buildings from certification. Not all old historic buildings are subject to monument protection. Methods of covert isolation that preserves the authenticity of cultural monuments and real estate in monument areas are a current challenge of heritage practices. The sustainability of the operation of historic buildings ultimately means the preservation and appropriate use of the heritage fund. The list of interventions that do not endanger the monumental values or use of the building is gradually expanding. This is mainly due to modern, increasingly sophisticated materials and technologies that are coming into practice.
