As a result of the negative effects of climate change and global warming seen today, the importance of the concept of sustainability is increasing. For this reason, priority should be given to keeping the amount of energy consumed at the lowest level during the architectural design phase and environmental friendliness of the preferred building materials. In the study, it was aimed to determine the criteria that the buildings created by considering the sustainability principles to be called Eco-Housing, to examine these criteria within the framework of ecological architecture and to evaluate the Eco-Housing projects that vary according to the climatic regions during the implementation phase. The material of the study consists of the literature that includes previous studies and applications related to Eco-Houses. The study was carried out in two stages. In the first stage, the place, criteria and principles of the concept of Eco-Housing in the literature were examined. In the second stage, Eco-Housing practices in regions with different climatic features were evaluated. In ecohousing, priority is given to supporting energy and resources. Eco-Houses, which are buildings where both traditional and modern architectural applications are combined and different disciplines and designs are integrated, include applications that people have preferred from past to present in order to catch the comfort conditions in nature. In Eco-Housing applications, attention should be paid to energy performance, water management, material selection, waste management and site selection. An integrated design process is used, which aims to reduce the energy need along with the consumption of natural resources. As a result of the correct management of this design process, it is possible to design Eco-Housing projects, which are ecological architectural products, in which environmentally friendly building materials are used, energy saving is ensured, sustainability principles are observed, suitable for the climatic characteristics of the region. The criteria taken into account in the projects implemented in different regions of the world also vary according to the climatic characteristics of the region. For example, the building materials used in hot regions exposed to sunlight for a long time, in places that receive constant precipitation during certain periods of the year, and in areas with lower temperatures are shaped according to climatic conditions. In line with the examinations, it was concluded that the structures with Eco-Housing features should be designed by paying attention to the climatic characteristics of the region they are located in.
