Abstract

Energy efficiency and hygrothermal performance of retrofitted historical building envelopes under climatic conditions of Prague is analyzed in the paper. In order to meet the requirements on the original facade appearance of buildings belonging to architectural heritage, the retrofitting is carried out using different types of interior thermal insulation systems. The computational results indicate that hydrophilic or capillary active materials can represent a suitable material solution as they can significantly improve the energy efficiency (up to 87% in the studied cases) while their hygrothermal performance is good from a building physics point of view.
