The building and construction sector accounts for 36% of global energy consumption and 39% of CO2 emissions, contributing to climate change. To mitigate this impact, improvements are needed in the building stock, particularly through energy-efficient retrofits to the existing structures. The study focuses on a residential building in Istanbul (temperate-humid climate) and Diyarbakır (hot-dry climate) in Turkey to analyze their behavior and the effects of implemented retrofits on energy efficiency. As climate change leads to increasing temperatures in Turkey, the importance of reducing cooling loads during summers becomes more evident in building retrofits. The study explores various improvement methods, such as adding solar shading systems, replacing glass with solar low-e systems, and using phase-changing materials to increase thermal inertia. These improvements have shown promising results in reducing summer cooling loads in both cities. Cost analysis of the improvements revealed that individually changing the glass system is the most effective and cost-efficient method. However, combined retrofit scenarios offer significant cooling load reductions, though their cost-effectiveness is relatively lower. Overall, this research highlights the urgent need to enhance the energy efficiency of buildings to combat climate change and emphasizes the importance of tailored approaches considering the specific climate conditions of different regions.
