Buildings - especially the residential buildings - are among the high priority areas in climate change due to their large share of CO2 emissions, their significant energy saving potentials and the increased comfort expectations of their occupants. A systematic and numerical investigation of how building performance will be affected by climate change in the future is crucial for both retrofitting the existing buildings and making long-term strategical decisions. This paper presents the simulation-based results of the climate change impact assessment for a typical multi-storey residential building in Istanbul. In this study, RCP4.5 and RCP8.5 scenarios - representing the low/medium and high CO2 emission scenarios - defined by the Intergovernmental Panel on Climate Change (IPCC) are used to generate two different climate data sets for 2060. Three cooling scenarios (natural ventilation, hybrid ventilation and air-conditioned) have been developed to represent different building usage profiles for the building simulations. Investigated performance metrics were selected as building heating/cooling energy consumption, CO2 emission and occupant thermal comfort. Analysis results analysis show that the predicted temperature rise will have a strong impact on the building cooling energy consumption and/or occupant thermal comfort. The results indicate the necessity of taking measures for adaptation of buildings to the changing climate and the importance of decarbonization of electricity generation to mitigate the effects of climate change. This study will also serve as a basis for future retrofit studies for the changing climate.

Evaluation indicators for selection of sustainable building materials Canarslan, Özgecan; Elias Özkan, Soofia Tahira; Department of Building Science in Architecture (2007) Environmental issues have gained importance due to global environmental threat, such as depletion of energy resources and the impacts of climate change. The building sector is responsible for almost half of the impacts on the environment. Hence, this study focuses on the importance of environmental impacts of building materials. In this regard, firstly, sustainability indicators for building materials were determined and the environmental impacts of selected building materials were studied. Then, the evalua...
Assessing thermal performance of office building envelopes : a case study on energy efficiency Sürmeli, Ayşe Neşen; Elias Özkan, Soofia Tahira; Department of Building Science in Architecture (2004) In this study, the energy conservation potential of selected retrofitting interventions on an office building were investigated, on the basis of which some rational strategies for the improvement of building envelopes in terms of energy, environment and comfort design were proposed. Examined were various measures on envelope constructions that can be retrofitted to existing buildings. By using simulation techniques, the effectiveness of such measures in reducing energy consumption and environmental threat w...
Effect of envelope insulation on building heating energy requirement, cost and carbon footprint from a life-cycle perspective Altun, Murat; Akgül, Çağla (Journal of the Faculty of Engineering and Architecture of Gazi University, 2020-01-01) Space heating is the dominant item of energy consumption of buildings in Turkey. Effective building envelope insulation, especially in early design phase, is the most common passive solution that significantly reduces the annual heating energy requirement of the building. This work aims to assess the effectiveness of additional envelope insulation investments at the early design phase of buildings for all cities in Turkey. The study utilizes the current (2008) and draft 2013 versions of the TS 825 standard ...
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...
Scale-model and Simulation-based Assessments for Design Alternatives of Daylight Redirecting Systems in a Side-lighting Educational Room Kazanasmaz, Tuğçe; Hancı Geçit, Burçin; Sevinç, Zeynep; Altınkaya, Gülce; Aksakarya, Gizem; Ergin, Meltem; Öztürk, Yasemin; Grobe, Lars O. (Middle East Technical University, Faculty of Architecture, 2017-11-20) Daylight has been proven to have positive effects on well-being, comfort and performance of occupants in buildings; it specifically increases learning performance in educational buildings. Side-lighting from one direction leads to unbalanced and insufficient illuminance, especially in large and deep spaces. A design studio at the Izmir Institute of Technology (IZTECH) in Urla, Turkey, has been chosen as an example of a space in such a context. Its geometrical attributes has taken to be the baseline. First, ...
