Abstract
This study aims to address the issue of reducing heating loads in buildings located in cold climates, particularly in buildings of worship, by investigating the effects of various proposals for improvement. These proposals include insulation thickness, transparency ratio, glazing type, and green roof, on the thermal comfort and energy performance of a building situated in a cold-semi-arid climate region. In this research, the Yasamkent Mosque in Ankara, Turkey, was selected as a contemporary architectural example and case study. The effects of retrofitting scenarios on the thermal comfort and energy consumption of the building were evaluated using a simulation program. The results of the study suggest that the optimal retrofitting scenario for the building envelope involves the installation of a green roof and 30% transparency ratio with Low-E glazing, as well as an insulation thickness of 15 cm on the external walls and roof, and 7.5 cm thermal insulation for the floor. These improvements led to a 6% increase in indoor thermal comfort and a 23% decrease in annual energy consumption. This study is expected to contribute to guiding improvements in the energy performance and thermal comfort of existing buildings of worship in colder climate regions.
