As the sustainability principle began to manifest itself more in 21st-century buildings, renewable energy-based systems used as a requirement of this principle are frequently seen in architecture. The most prominent of these are Solar Energy Systems. In this respect, as a result of the buildings' efforts to coexist with this technology, components of Solar Water Heating Systems (SWHS), a new architectural element, started to be included in the buildings. Even though these mechanisms have

... ges make our lives easier and serve the sustainability principles, the increasing use of them rapidly in the buildings brings about some problems such as aesthetical, and structural. As a consequence of such problems arising with these systems' widespread use in residential areas, it is essential to examine these additions' relations with buildings and the urban environment. If the buildings that are part of the cultural heritage has these systems require conservation and are located in the historical texture, it is even more essential to emphasize. To manage the sustainability of historical environments, these systems' existence should be determined in either building at historical settlements or registered buildings, and some arrangements should be made by examining their relations with buildings. Considering all, it is aimed to analyze and evaluate the relations of these systems and buildings within the Sivrihisar Urban Protected Area, which has historical and cultural importance in Eskişehir. The study of the data obtained from the buildings in these regions through fieldwork was handled with comparative graphical, mapping methods, and supported with visual representation ways.
