Abstract:

Daylight is one of the main factors among the features that determine the original space qualities in traditional houses. The daylight features of the spaces also determine the authentic space atmosphere and should be considered among the features to be preserved in the usage decisions. In traditional dwellings in Anatolia, the main room is the most lavish room, which has projections and is surrounded by windows on three sides. Therefore, in the buildings that are conserved for reuse, the main room should maintain its original daylight features. The aim of this study is to draw attention to the maintenance of daylight features in the restoration decisions of traditional dwellings. Within the scope of the study, daylight performance of the main rooms of Kaçıklar and Zabunlar Houses selected in Kula, Manisa was evaluated. The illuminance levels of the main rooms were measured during the four seasons; by calculating the ratio of the window area to the floor and wall areas, reflectance values of the surface materials and window glass permeability values were calculated. In the study, it was determined that the main room daylight performance of the Kaçıklar House was not sufficient for all four seasons, while it was for the Zabunlar House. As a result, while the restoration decisions are developed, opening the closed window in the main room of Kaçıklar House, cleaning the paint on the top windows and and selecting a light-coloured wall finishing material will increase the reflectance value and will positively affect the daylight performance; in Zabunlar House, on the other hand, removing the existing wooden glazing in the sofa in order to increase the daylight provided through the sofa and increasing the reflectance value by choosing a light-coloured wall finishing material will positively affect the daylight performance of the main room.
