    A stepwise approach to nZEB transition and GHG emission reduction in public buildings in Türkiye: A case study of the IMM Fatih Sports Centre
    (Gazi Üniversitesi, 2026) Akgüç, Alpay; Taşçı, Gözde Gali
    This study pioneers the evaluation of nearly zero-energy building (nZEB) transformation potential in publicly owned sports facilities in Türkiye. Focusing on the Fatih Sports Complex in Istanbul, the research aims to align the building with the nZEB criteria defined in the Building Energy Performance (BEP) Regulation and support Türkiye’s 2030 greenhouse gas (GHG) emission reduction target of 41%. The study followed a three-phase approach. In the first phase, the building envelope was upgraded in line with the TS825:2024 standard, and artificial lighting systems were redesigned to meet ANSI/ASHRAE 90.1:2022 lighting power density (LPD) limits, raising the building’s Energy Performance Certificate (EPC) rating to Class B. In the second phase, 225 half-cut photovoltaic (PV) panels (550 Wp each) were installed on the roof, supplying 11% of the building’s primary energy demand from renewable sources. In the third phase, the combined measures achieved a 48% reduction in total GHG emissions. The originality of this study lies in being the first in Türkiye to model and simulate a comprehensive nZEB transformation of a public sports facility, integrating energy performance improvements, renewable energy integration, and emission reduction. The results offer a practical roadmap for public buildings in achieving national energy efficiency and carbon neutrality goals.

    Evaluating cost-optimality of high-rise buildings by considering outdoor air rates in TS825 standard
    (IGI Global, 2024) Akgüç, Alpay; Yilmaz, Ayse Zerrin
    The construction of high-rise residential buildings has been increasing dramatically, but a crucial part of energy consumption of these buildings still depends on fossil fuels. Furthermore, the global costs of these buildings are extremely high compared with the other residential building types due to the mechanical ventilation demands. Thus, it is necessary to improve through both energy consumption and global cost of these buildings. In the present study, the cost-optimum energy-efficient level of the high- rise residential building in Turkey was evaluated by using the cost-optimal methodology introduced in Directive 2010/31/EC by European Union. When the fresh air rates of air handling units of the case study building were revised in accordance with TS825 standard, which is the national Turkish building code of Turkey, it was concluded that the annual primary energy consumption and global cost of this building was improved by 44.2% and 22.73 e/m, respectively. © 2024, IGI Global.

    WATER EFFICIENCY POTENTIAL OF UNIVERSITY CAMPUSES TOWARDS LEED CRITERIA: A CASE STUDY IN TURKEY
    (2025) Akgüç, Alpay
    Many buildings worldwide feature outdated and inefficient sanitary systems, which is particularly pronounced in densely populated university campuses, where high water consumption poses a significant challenge to sustainable water management. This study aimed to investigate the impact of installed sanitary systems on water consumption in a university building in Istanbul and assess potential savings through high-efficiency systems as per the LEED certification criteria, and emphasize the environmental, social, and economic significance of improving water use efficiency on university campuses in Turkey. Annual consumption was first calculated using the TS1258 standard, then a new model with efficient fixtures was developed. Results showed that the proposed systems could increase water efficiency by approximately 78% with a payback period of 14 months. From an environmental perspective, the study highlights the importance of water conservation, and from a social standpoint, it promotes equity in water access, and economically, it demonstrates significant cost reductions and long-term financial savings. Furthermore, the research identifies a gap in the TS1258 standard, which did not consider gender-based differences in water use. By presenting key data for policymakers and administrators, this study aims to emphasize the necessity of adopting more efficient water management strategies in educational institutions and contribute to future research on sustainable campus development.
