Climate change (CC) and urban heat island (UHI) are important environmental forces that have serious consequences for the existing buildings, such as increased resource consumption and environmental footprint, adverse human health effects and reduced occupant comfort. In this context, educational buildings represent a critical category amongst other building typologies, due to their high energy use, high occupant density, atypical daily/annual occupancy patterns, and their occupants’ high vulnerability to heat. Poor indoor conditions can reduce the health and productivity of students and teachers, worsen learning performance and reduce attendance. Retrofitting educational buildings is an effective solution to tackle this challenge. This study investigates the impact of CC&UHI on educational building performance and demonstrates the effectiveness of passive retrofit scenarios targeting CC&UHI mitigation and adaptation. These investigations are based on a systematic approach that consists of (i) the generation and analyses of CC&UHI-modified weather datasets, and (ii) simulation-based comparative analyses of the as-is building and various retrofit scenarios. An existing secondary school building in Ankara, Turkey is selected as a case study for evaluations of the selected performance indicators including energy use, global warming potential (GWP) and thermal comfort. Obtained results indicate that total energy consumption can be reduced up to 50% with retrofit, whereas possible reductions in indoor discomfort are even more pronounced, underlining the significance of selecting the optimal combination of passive measures for maximum impact towards the adaptation of the existing educational buildings to the changes in climatic conditions.

Impact Assessment of Urban Regeneration Practices on Microclimate in The Context of Climate Change Akköse, Gizem; Balaban, Osman; Department of Earth System Science (2022-2-10) The annual ever-increase in population, urbanization, industrialization, and CO2 or greenhouse gas emissions brings with it important environmental crises. Climate change and urban heat islands (UHI) are crucial environmental crises that have serious consequences on the performance of the built environment and the comfort and health of users. Moreover, mass migrations from the urban areas and unhabitable cities are envisaged as a result of climate change. To minimize the impacts of climate change and ensure...
Assessment of urban heat: approaching walkability from a multi-scalar perspective Mushtaq, Shiza; Akkar Ercan, Zübeyde Müge; Urban Design in City and Regional Planning Department (2023-1-27) Under the impacts of climate change, the growing intensity of heat waves pose a significant public health risk and affect daily life both in living spaces and public places. However, it is possible to mitigate urban heat, increase urban mobility and promote walkability with data-informed urban design policies. The literature on urban mobility examines the walkability capacity of public spaces concerning environmental, social, and human physiological factors. In contrast, fewer studies address the impact of ...
Comparison of BEST and LEED green building rating systems through cost based optimization Uğurlu, Bengisu; Aksoy, Ayşegül; Department of Environmental Engineering (2020-1-25) Buildings have significant effects on climate change due to vast resource consumption and pollution generation. Improving the effective use of limited resources and constructing environmentally friendly buildings are important in the realm of mitigations for climate change. Several countries have their green building rating systems tailored towards their regulations, distinctive climatic conditions, unique cultures and traditions, diverse building types and ages, or wide-ranging environmental, economic, and...
Climate Change Impact on Multi-Objective Optimization: A Case Study on Educational Buildings Akın, Şahin; Işeri, Orçun Koral; Akgül, Çağla; Erdoğan, Bilge; Gürsel Dino, Ipek (null; 2020-05-23) The changing weather conditions due to global climate change is expected to have a direct impact on buildings’ energy demand and occupant comfort. These conditions are estimated to become more challenging for educational facilities due to their high occupant density and the students’ sensitivity to heat. This study aims to present an approach for a comparative analysis for multi-objective optimization results that are projected under different climate change conditions. Two separate optimization processes w...
Architectural design for climate change mitigation and adaptation strategies in existing buildings Akköse, Gizem; Gürsel Dino, İpek; Department of Architecture (2019) Climate change has been proven largely to be a consequence of human activities and has a destructive impact on ecosystems. Societies and economies have become a growing global concern for the last few years and the building industry has a key role in this change due to its huge amount of environmental footprint. The energy consumption and greenhouse gases emissions of the built environment influence the climate in a negative way while the changing climate also influences the energy and thermal performance o...
