    Determining accessibility levels on pedestrian routes: The sample of Çukurova University campus example
    (Gazi Univ, Fac Engineering Architecture, 2024) Sahin, Yelda Durgun; Sirel, Berrin
    Graphical/Tabular Abstract In this study, a method to determine the accessibility level of pedestrian roads and sidewalks was proposed and applied in a university campus as sample area. The flow chart of the study is illustrated in Figure A. Figure A. The flow chart of the study Purpose: In order to ensure accessibility to campus area, some basic principles must be followed. In this study, the accessibility standards determined by various countries were examined comparatively, and the accessibility criteria were determined by evaluating them together with the standards determined by TSE in Turkiye. These criteria were used to measure spatial accessibility of pedestrian routes. The weighting of the criteria for measuring spatial accessibility constituted the main problem of the study. Theory and Methods: With the specific structure of the analytical hierarchy process (AHP) method, which is one of the multi-criteria decision-making analysis techniques, the decision problem is modelled to determine the weighting of the criteria. Within the scope of the study, the spatial accessibility problems of the northern campus pedestrian routes of cukurova University in Turkiye were discussed, the barrier-free access project designed in this direction was examined along with the criteria, 12 different sample areas were selected, and the accessibility quality of the areas were determined using the weights of criteria. Results: Accessibility rates in the study area vary between 21% and 41%. The three most important criteria for ensuring accessibility on pedestrian routes has been determined as ensuring the continuity principle, availability of sufficient lighting, the use of direction/tracking stones for the visually impaired. Conclusion: The region with the highest accessibility level was calculated as the assembly area. The area with the lowest level of accessibility was determined as the pedestrian path and sidewalks below 3 m, which constitute a large part of the pedestrian access route, and it was determined that the accessibility of the campus adversely affected. It is thought that study outputs will provide both important output to other studies to evaluate the quality of urban accessibility and improve accessibility and to authorities or managers in the urban service area to assess the quality of urban accessibility and improve accessibility.

    HOLISTIC APPROACH TO ECOLOGICAL DESIGN PARAMETERS OF BUILDING AND LANDSCAPE DESIGN ON OUTDOOR THERMAL COMFORT IN HOT, HUMID CLIMATE
    (Univ Zagreb Fac Architecture, 2023) Sahin, Yelda Durgun; Altunkasa, Ceren
    In this study, academic staff residential buildings were studied as part of a university campus located in a hot and humid climate zone in Turkiye. Within the scope of the study, the energy efficient architec-tural and landscape design decisions of the buildings built in 1976 were examined. The aim was to determine the energy performance of buildings built about 50 years ago and to quantify the effect of chang-ing landscape conditions on thermal comfort. In this aim, the outdoor thermal comfort level was determined by creating microclimate simu-lations for the hottest day and time of the year. Microclimatic analy-ses were performed with ENVI-met software and thermal comfort was evaluated with two metrics, average PMV and ASHRAE scale. The energy performance of the buildings was determined using ecological design parameters. An approach to global environmental problems is the use of ecological design principles, including architectural and landscape design principles. It is important to consider both architec-tural design criteria and landscape design criteria when discussing an ecological design in the built environment. Architectural and land-scape design decisions for hot and humid climate regions together increased energy efficiency by 51.1% to 75.5%. It was found that although the plant design improves energy performance in buildings by that range value, it improved outdoor thermal comfort by 15% to 22%. As a result, the study evaluated climate-balanced plant design with building energy performance in order to improve outdoor ther-mal comfort.

    Spatial infection control in burn center organization: a burn center design experience for evidence-based architecture
    (Emerald Group Publishing Ltd, 2023) Sahin, Yelda Durgun; Yavuz, Osman Metin; Kesiktas, Erol
    PurposeThis study discusses that the necessary criteria and the solution approach taken to resolve the main spatial infection problems with a burn center design should be evaluated holistically to achieve spatial infection control in a burn center. The burn center design plays an important role in protecting severely burned patients from infection because the microbial flora of the hospital can affect the infection risk. In hospitals, sterilization and disinfection are the basic components of infection prevention; however, the prevention and control of infection for burn patients also requires the design of burn centers that adhere to a specific set of criteria that considers spatial infection control in addition to appropriate burn treatment methods and treatments. In this study, a burn facility converted from a burn unit into a burn center is introduced and the necessary design inputs for the transformation are discussed because there is no holistic study in the literature that delas with all the spaces that should be in a burn center and relations between spaces. This study aims to define the functional relations between each of the units and the spaces that change according to different sterilization demands in the burn center for ensuring spatial infection control. Furthermore, it aims to propose a method for ensuring continuity in the control of spatial infections. Design/methodology/approachThe burn care and health facilities guidelines are examined within the framework of spatial standards, together with a comprehensive literature review. The design method was based on the spread of microorganisms and the effect of human movement on space and spatial transitions in the burn center, according to all relevant literature reviews. To determine the extent to which the differences in treatment protocols of burn care guidelines were reflected in the space, interviews were conducted with burn facility officials. The plan-do-check-act (PDCA) method is also modeled to ensure the continuity of infection control in the burn center. FindingsThe burn center design findings are classified under three main headings, namely, location of the burn center in the hospital, spatial organization and physical features of the burn center and the air flowing system. The importance of the interactions among the criteria for spatial infection control has been revealed. Due to the physical space characteristics and air flow characteristics that change according to human movement and the way microorganisms spread, it has been seen that designing the air flow and architectural aspects together has an effective role in providing spatial infection control. Accordingly, a functional relation scheme for the center has been suggested. It is also proposed as a model to ensure the continuity of infection control in the burn center. Practical implicationsThis research presents spatial measures for infection control in burn centers for practitioners in health-care settings such as designers, engineers, doctors and nurses. The PDCA method also leads to continuity of infection control for hospital management. Originality/valueThis is the first study, to the best of the authors' knowledge, to focus on developing the criteria for spatial infection control in burn center. Moreover, the aim is to create a function chart that encompasses the relationships between the units within the burn center design so that infection control can be coordinated spatially.
