This study investigated the impact of two types of internal blinds on the indoor thermal environment of a highly glazed office room in Istanbul during summer. The research examined four configurations: (i) no blinds, (ii) roller blinds, (iii) layered roller blinds in night mode and (iv) layered roller blinds in day mode. Measurements of air velocity, average radiation temperature, air temperature and relative humidity were conducted to assess thermal comfort. The findings revealed that internal blinds significantly influence thermal comfort in radiantly cooled office spaces during summer. Without blinds, the indoor environment only met ISO 7730 comfort category C, with average predicted mean vote (PMV) and predicted percentage of dissatisfied (PPD) values of 0.6 and 12.5%, respectively. However, with internal blinds, comfort categories A and B were achieved, resulting in improved thermal comfort levels, with average PMV and PPD values ranging from 0.2 to 0.3 and 6% to 7.5%, respectively. Roller blinds, in particular, proved highly effective in enhancing thermal comfort and reducing mean radiant and indoor air temperatures in highly glazed radiant cooling offices. This demonstrated their energy-efficient potential for improving indoor thermal comfort.

Worldwide, especially in societies with higher education levels, traditional settlements are important components of cultural heritage in terms of sustainability. However, the recent wave of urbanisation that has been experienced in Turkey has placed significant pressure on traditional structures. The District of Kemaliye, which has largely preserved its traditional texture for various reasons, is a small town in the Erzincan Province of Turkey. The aim of this study is to determine the quality of life of the traditional settlement pattern of Kemaliye to contribute to its ecological, spatial and socio-cultural sustainability. A public opinion survey was carried out with the aim of identifying the public's needs and demands and its socio-cultural characteristics. The survey also aimed to determine the quality of urban life in Kemaliye. Multidimensional statistical techniques were used to identify the most important environmental, socio-cultural, infrastructural and regional factors that affected the public's views of quality of urban life in Kemaliye. Based on these findings, suggestions were formulated for the efficient use of resources in urban redevelopment efforts and to provide a basis for the new settlement plans that are projected to be carried out for the city centre of Kemaliye and its vicinity.
