| Summary: | The degradation of wood in historic structures is influenced by a combination of environmental and biological factors. This study examined the chemical deterioration of wood in historical wooden houses in Rize, Türkiye, with a specific focus on the impact of altitude and facade orientation. Samples were collected from the south-facing facades of six historical buildings situated at varying elevations. Fourier Transform Infrared spectroscopy was employed to assess the chemical changes in the wood, specifically in the cellulose, hemicellulose, and lignin content. A comparison was made between weathered samples and a new control specimen to assess the extent of degradation. The Carbonyl Index (CI) and Lignin Index (LI) were calculated to quantify structural changes. The results revealed substantial degradation in the surface chemistry of aged wood, primarily due to photodegradation and environmental exposure. No systematic correlation was found between altitude and degradation levels, suggesting that local microclimatic factors, rather than elevation alone, predominantly influence chemical deterioration. South-facing facades exhibited greater degradation, likely due to increased exposure to UV radiation. The findings underscore the importance of understanding site-specific environmental influences in heritage conservation, providing a foundation for future restoration efforts. These results emphasized the importance of integrating chemical characterization with environmental monitoring to optimize conservation practices. |
