Abstract

The daylighting feature of historical buildings can be accepted as an intangible heritage since it contributes to the unique atmosphere of the buildings. However, with the change of the built environment and the change of the historical building itself, the level of daylight intake of historical buildings changes. This study contributes to the field by revealing the daylighting performance changes of a historical khan building which has a unique architectural characteristics. The changes in the daylighting levels of Buyuk Yeni Khan, one of the largest historical khans in Istanbul, are examined through its modifications. Using 3D Lidar scanning technology, the current state of the khan is scanned. The daylight intake and glare analyzes of the khan for its current and original states are made through simulations, and the values found are compared. DA, cDA, UDI, sDA and DGP metrics are used in the simulations. As a result, due to the changes such as enlargements along the arcades, additional overhangs and the change of window ratios of the facades of the rooms on the ground floor, the rooms of the khan have different daylighting values compared to its original state.

伊斯坦布尔一座历史悠久的坎儿井建筑室内采光性能变化评估

历史建筑的采光特征可以被视为一种非物质遗产，因为它有助于营造建筑的独特氛围。然而，随着建筑环境的变化和历史建筑本身的变化，历史建筑的采光水平也会发生变化。本研究通过揭示一座具有独特建筑特色的历史性坎儿井建筑的日照性能变化，为该领域做出了贡献。本研究通过对伊斯坦布尔最大的历史建筑之一 Buyuk Yeni Khan 的改造，对其日照水平的变化进行了研究。利用三维激光雷达扫描技术，对汗宫的现状进行了扫描。通过模拟，对当前和原始状态下的日光摄入量和眩光进行了分析，并对发现的数值进行了比较。模拟中使用了 DA、cDA、UDI、sDA 和 DGP 指标。结果显示，由于拱廊的扩大、悬挑的增加以及底层房间外墙窗户比例的改变等变化，大汗的房间与原始状态相比具有不同的采光值。
