The use of sun shading elements frequently seen in the residential tradition of the Aegean region. Controllable traditional venetian blinds (shutters) carried to the present through periodic changes are prominent design elements of the architectural heritage. This study aims to understand the effectiveness of these traditional sun control elements in terms of energy efficiency in the cooling season within three different locations (north, mid, and south Aegean coast), and daylighting illuminance level adaptations in Izmir, mid Aegean coast area, with 2 different materials, and 3 different blind angles. To obtain data, on- site measurements conducted in the field of interest. The sunshade illuminance level measurements of the studied residential example used as a source for more effective use of IES (VE) energy models before testing further variations. The main objective is to comprehend one of the traditional methods of coping with the effect of the sun and to understand the reasons from a technical point of view for future adaptations. As a result of the analysis carried out on the most critical days of sunlight, the evaluation of solar shading elements in terms of daylighting balance and cooling loads in traditional houses, will provide us the understanding of the effect of sun control variations in the defined temperate climate region. Tested methodology will guide future case studies.
