Evaluation of the effects of material and color use in architectural facade design on user perception: the Ankara-Çankaya example

Architectural facades, which are the outer faces of buildings, are the first place where communication is established between the user and the city with their designs and are considered as an interface. In architectural facade design, color selection, which is at least as important as parameters such as size, shape and scale, is one of the most important components that form the outer shell of the building. In recent years, urban structure and building designs have been changing according to new needs due to the rapidly increasing population and migration from cities. The color factor is also affected by this change. In this case, material, product, user and designer are effective. In this study, it is aimed to examine how user preferences change according to their perception through the determined study areas. For this purpose, three examples from different housing and housing group designs from Ankara province were determined, analyzed and compared. The study area consists of the first mass housing example of Turkey, the Saraçoğlu Neighborhood, Yeşiltepe Blocks Project, planned in the 1940s, and the Merkez Ankara project residences planned after 2015, close to today. In this context, the facades of the selected examples were examined and questions were prepared on form, material, texture and color, the facades of the relevant projects were visualized digitally and supported by a survey study, and people's facade preferences were examined on the basis of their first-view perceptions on facade design, compatibility, fullness-emptiness, perception and material. It is anticipated that the results obtained at the end of the study will be an evaluation tool in understanding user perception and in the future in the design of housing and housing groups. Conducting similar field studies in different contexts will enable designers and users to obtain measurable results in the decision-making phase.
