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 social priorities. Today in the world, the most popular green building rating system is based on the LEED system of USA. Turkey has developed its own rating system, BEST, in August 2019. This study aims to compare LEED and BEST rating systems using a cost-based optimization. The study also aims to propose a guideline to stakeholders while choosing the green building features to obtain green building certificates in Turkey at the least cost. In the study, an optimization model is developed in which cost-related data, electricity consumption, and water usage analyses are integrated. The model is solved using LINGO. The optimization model is run for case studies involving 4-, 5-, 7-, and 12-storey buildings in Ankara for a total of 16 scenarios. Results show that Good and Excellent certification levels of BEST are feasible choices considering water and electricity savings of residents over a period of 10 years. The Good certification level is the most feasible choice with its significantly cheaper initial cost with respect to Excellent level and considerably high savings. Moreover, the only certification level that compensates the investment cost after 10 years is the Good level. The least feasible choice is the Very Good level with the highest initial cost and considerably low savings. Furthermore, building systems/materials/equipment selected for any of BEST certification levels are not sufficient to achieve the Platinum level of LEED, but Certified, Silver, and Gold levels are achievable.

Literature review on BIM-based building energy performance optimization Can, Esra; Akçamete Güngör, Aslı (İstanbul Teknik Üniversitesi; 2020-11-14) Buildings comprise a large part of global energy consumption and make a significant contribution to overall CO2 emissions in the world. Therefore, increasing the energy efficiency of buildings becomes a priority to reduce these undesirable effects. Building energy performance assessments are complex multi-criteria problems as the energy performance is affected by many factors such as building orientation, envelope design, climate conditions, daylighting levels, and HVAC system usage schedules. This complica...
Educational building retrofit under climate change and urban heat island effect Akkose, Gizem; Akgül, Çağla; Gürsel Dino, İpek (2021-08-01) 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 h...
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...
Investment needs for climate change adaptation measures of electricity power plants in the EU Lise, Wietze; van der Laan, Jeroen (2015-10-01) Climate change is expected to have impacts on the power sector, leading to, among others, a need for adaptation measures in the sector in the near future. This paper analyses the need to adapt to climate change impacts for power generation technologies in Europe until 2100. Europe is broadly divided into four geographic climate zones, for which regional climate change impacts are quantified with the help of the ENSEMBLES RT2b data. The European future technology mix is based on two Eurelectric energy scenar...
Greenhouse gas emissions from global cities under SSP/RCP scenarios, 1990 to 2100 Gurney, Kevin R.; Kılkış, Şiir; Seto, Karen C.; Lwasa, Shuaib; Moran, Daniel; Riahi, Keywan; Keller, Meredith; Rayner, Peter; Luqman, Muhammed (2022-03-01) Projections of greenhouse gas (GHG) emissions are critical to enable a better understanding and anticipation of future climate change under different socio-economic conditions and mitigation strategies. The climate projections and scenarios assessed by the Intergovernmental Panel on Climate Change, following the Shared Socioeconomic Pathway (SSP)-Representative Concentration Pathway (RCP) framework, have provided a rich understanding of the constraints and opportunities for policy action. However, the curre...
