Calculation of Heat Energy Consumption by a Typical Historical Building with a Courtyard

The article presents the assessment of thermal protective properties for the enclosing structures of the particular historical residential building, considering the overall thermal balance of the building. Actual thermal resistance of the building was estimated taking into account the thermal resistance of all enclosing structures. In order to carry out the research and necessary calculations, external and internal environmental conditions were analyzed. The research exposes the calculations of transmission heat losses, heat losses occurring due to ventilation and air infiltration. Taking into account heat supply, solar heat input and all thermal losses, the annual heat consumption of the building was estimated. Proceeding from the results of the research the authors offer particular measures in order to improve energy efficiency of the building. Proceeding from the results of the research the authors prove the reasonability of creating a glass dome over the courtyard space in order to improve energy efficiency of the whole building.
