Özet:

Comprehensive studies are needed to discover materials and construction technologies contributing to the thermal performance of historical buildings and to keep them in working order over time. Examined in this study were the thermal performance characteristics of Şengül Hamamı, a 15th Century Ottoman bath, to discover original thermo-physical properties of historic materials and to assess thermal failures in present situation by taking into consideration recent incompatible repair work. The analyses were done by using non-destructive investigation methods, such as microclimatic monitoring, quantitative infrared thermography (QIRT), heat and water vapour transfer calculations, supported by laboratory analyses on thermo-physical properties of historic materials. The results were evaluated in terms of thermal properties of historic materials establishing the historic dome section, microclimatic characteristics of Şengül Hamamı, its original thermal characteristics, and thermal failures occurred in time due to wrong repairs. An in-situ assessment method was also developed for the identification of thermal and moisture failures at real boundary conditions by joint interpretation of QIRT and heat transfer calculation results. The study showed that historic dome structure of Şengül Hamamı was originally configured to provide sufficient thermal insulation characteristics owing to good thermal properties of its materials. That success was attributed to conscious use of low-density, high-porosity historic materials having low thermal conductance and high vapour permeability characteristics. It was seen that the thermal performance of historic structure was severely destroyed by recent repairs using concrete and cement-based materials, which were incompatible with historic fabric of the structure due to their different thermo-physical properties.
