Article Citation - WoS: 20Citation - Scopus: 17Optimizing Thermal Comfort in Physical Exercise Spaces: A Study of Spatial and Thermal Factors(Elsevier, 2024) Avcı, A.B.; Balci, G.A.; Başaran, T.Fitness centers have become famous for maintaining a healthy lifestyle. They require different thermal comfort conditions and higher fresh air supply rates than other indoor spaces. However, even well-designed centers may cause discomfort due to factors such as design decisions, ventilation, overheating, and overcrowding. The standards for fitness centers do not consider these specific requirements sufficiently, so this study focuses on understanding the thermal comfort requirements during physical exercise and evaluating spatial and thermal factors affecting the thermal environment around the body. The study investigated the ceiling height, lateral and frontal distances between machines, and vent locations as spatial factors and inlet temperature and air velocity as thermal factors. A thirty-minute moderate-intensity constant work rate exercise test was conducted in a controlled climatic chamber using a cycle ergometer with six healthy male participants. The experiment conditions were simulated in CFD software using the collected data. Once a validated simulation model was provided, computational models for different environmental and spatial scenarios for the five-person cycling class were generated. Using Taguchi L9 (34) orthogonal arrays method, nine spatial scenarios were simulated with three different thermal operations each. Optimal factor levels were determined by using thermal comfort conditions (based on predicted mean vote) around the body's thermal plume. The results showed that a ceiling height of 5 m, lateral and frontal distances of 1 m and 0.5 m between machines, and Type 2 (two inlets mounted on the ceiling) ventilation strategy were optimal for achieving better thermal comfort values in a thermal condition of 18 °C and 0.2 m·s−1. The study found that increasing the ceiling height and using cross-positioned vents that project air vertically from the ceiling improved the comfort conditions significantly. It is expected that these criteria, which were determined, compared with the standards and detailed, will contribute to the production processes of comfortable exercise spaces. © 2023 Elsevier B.V.Article Citation - WoS: 3Examining the Effect of Learning Environment on Student Behaviour Through Comparison of Face-To and Online Design Studio(2023) Doğan, Ceren; Yılmaz, EbruCovid-19 pandemic has affected the field of education, and transition to the distance learning has led to changes in the learning environment and pedagogical transformations. In this process, design studios, which are the basis of architectural education, were also maintained on online platforms. The aim of this study is to investigate the effect of the rapid learning environment change in the architectural design studio due to the Covid-19 pandemic on student behaviour. Examining students’ holistic perspectives and behaviours based on their experience in face- to-face design studios and online design studios, this research attempts to reveal the potential and challenges of face-to-face and online studios. In this study, students’ behavioural changes regarding face-to-face studio and online studio were measured using the survey method, and these two learning environments were interpreted over six themes (peer learning, socially mediated learning, self-efficacy, self-regulation, motivation, and communication with the instructor) by using the survey results, the course structure and the theoretical framework. The findings reveal that change in the learning environment affects student behaviour and that face-to-face design studios and online design studios have different potentials and limitations. In addition, the course structure of the face-to-face studio and online studio, the tools and methods used in learning, the way of communication and collaboration vary depending on the structure of the learning environment. This study reveals that the face-to-face design studio is a learning environment where the social structure of the studio is developed, peer learning is supported, and methods such as physical model and hand-sketching are used as well as digital tools during communication with the instructor. It shows that the most important potentials of the online studio are that it offers a flexible learning environment, does not have time and place restrictions, allows for cross-cultural and inter-institutional collaboration, and supports self-study. As a result, the research shows that online studio experiences gained during the pandemic period can offer the opportunity to create blended learning environments by adding online features to the traditional face-to-face studio.Article Citation - WoS: 1Children in Urban Environments: a Case Study From a Dense Neighbourhood in Izmir-Turkey(Yıldız Teknik Üniversitesi, 2022) Dikmen Güleryüz, Oylum; Doğan, Fehmi; Kasalı, AltuğThe aim of this study is to understand children's engagement with their urban outdoor environments in Izmir-Turkey, a city with a high urbanisation rate, and to explore the factors that affect their outdoor preferences outside of their school time. The study consists of a field study conducted in a densely populated middle-income neighbourhood. Participants are fourth-grade children from a state-run primary school aged 9-11 years (n=44) and their parents (n=40). The study followed a multi-methodological approach, employing questionnaires, drawing and story writing tasks as data collection methods. Results of the study showed the strong tendency to prefer outdoors during their free time even when their neighbourhood is a high-density urban settlement with limited opportunities for outdoor activities. In the studied neighbourhood, most of the participants mentioned the schoolyard over other locations as their preferred place fin- outdoor play. Other than the schoolyard, the children mainly reported familiar places in their neighbourhoods, close to their local environments which were also depicted in their drawings and described in their stories. From the perspectives of urban designers and policy-makers, the findings of the study highlight aspects to be concerned about opportunities for outdoor play in high-density and urbanised central neighbourhoods.Article Citation - WoS: 2Cephe Yönlenmesinin Tarihi Konutların Enerji Kullanımına Etkileri: Güneybatı Anadolu’da Dış Sofalı Konutlar(Yıldız Teknik Üniversitesi, 2022) Timur, Barış Ali; Başaran, Tahsin; İpekoğlu, BaşakCephe yönlenme durumu, yapıların enerji kullanım miktarlarını etkileyen önemli bir tasarım parametresi olarak kabul edilmektedir. Bu parametre özellikle yeni yapı tasarımı alanında, yönlenme optimizasyon kararları geliştirmek üzere birçok araştırmada incelenmiştir. Buna karşılık, tarihi yapıların yönlenmesi ve enerji kullanım miktarları arasındaki ilişkiyi irdeleyen çalışmalar sınırlıdır. Bu çalışmanın amacı, Anadolu coğrafyasında yaygın bir tarihi yapı türü olan dış sofalı konutların Muğla kenti örnek yerleşmesindeki hâkim yönlenme durumları ile enerji kullanım düzeyleri arasında belirgin bir ilişki olup olmadığının araştırılmasıdır. Araştırma yöntemi, DesignBuilder v.5.4.0.21 yazılımında gerçekleştirilmiş olan yapı ısıl modellemesi ve simülasyonudur. Çalışmada, örnek bir tarihi konutun mimari özellikleri kullanılarak oluşturulmuş sanal bir yapı modelinin sofa yönlenme durumu, ana ve ara yönlere göre değiştirilerek ısıl simülasyonları gerçekleştirilmiş ve simülasyonlar sonucu hesaplanan ısıtma ve soğutma enerji ihtiyaçları karşılaştırılmıştır. Simülasyonlar, karşılaştırmalı olarak önce yapı çevresindeki kütle ve peyzaj elemanlarıyla sonra bu elemanlar olmadan iki sonuç seti için gerçekleştirilmiştir. Simülasyonlar sonucunda, örnek yapı türü için en iyi ve en verimsiz yönlenme durumları arasında enerji kullanımı açısından hesaplanan oransal farkın %1,3 ile %2,2 arasında olduğu saptanmıştır. Bu sonuca göre, örnek yapı türü enerji kullanım durumunun çok yüksek oranda yönlenmeden bağımsız olduğu, bu nedenle de örnek yerleşmedeki dış sofalı konutlar için hâkim yönlenme tercihi ile yapı enerji kullanım düzeyleri arasında dikkate değer bir ilişki olmadığı belirlenmiştir.Article Citation - WoS: 30Citation - Scopus: 30Thermal Retrofitting for Sustainable Use of Traditional Dwellings in Mediterranean Climate of Southwestern Anatolia(Elsevier, 2022) Timur, Barış Ali; Başaran, Tahsin; İpekoğlu, BaşakThermal retrofitting implementations are crucial for safeguarding the functional sustainability of historical buildings as they can improve the thermal performance of these buildings while maintaining thermal comfort for their occupants. This study aims to examine the thermal behavior of a common historical building type in Anatolia / Turkey, the traditional houses with exterior hall (sofa), and to determine enhancement potentials of possible thermal interventions. Research method consists of on-site thermal measurements, laboratory analyses on traditional construction materials and transient thermal analyses utilizing simulations on DesignBuilder software. Study cases were selected from both urban and rural sub-settlements. The results demonstrated that the thermal insulation works within floor assemblies, airtightness measures, adding secondary glazing to windows and suggesting transparent circulation corridors provide significant energy improvements. These interventions would save 26.5% of building energy consumption in the urban and 30.4% in the rural sub-settlements when applied together. Furthermore, when the integration of a modern HVAC system, ground-source heat pump is implemented, these improvement rates can be increased to more than 60%. Consequently, it was determined that the cases have significant potentials for thermal enhancements which renders the application of thermal interventions as a capable conservation tool.Article Citation - WoS: 1Sweeping the Meydan: Home and Religious Ceremony Amongst the Alevis(UAAC-AAUC (University Art Association of Canada), 2020) Andersen, Angela; Gündüz, CanLes alévis de Turquie parlent de la tradition qui consiste à organiser des cems, cérémonies en congrégation, dans les maisons des guides spirituels héréditaires et d’autres membres de la communauté. L’alévisme, qui regroupe les pratiques des lignées spirituelles kurdes et turcophones d’Asie occidentale issues de la famille du prophète Mahomet, est historiquement suivi sans l’utilisation des bâtiments de la mosquée, au contraire deleurs voisins musulmans sunnites. Dans cet article, nous combinons l’analyse architecturale avec des histoires orales recueillies auprès d’alévis pratiquants pour examiner les maisons alévis utilisées pour la cérémonie. Les pièces et les arrangements domestiques décrits par nos interviewés sont des études de cas dans le cadre d’un examen plus large de la vie religieuse et du comportement au sein du foyer et soulignent l’expérience de communautés spirituelles marginalisées dans les contextes rural et urbain. Notre recherche originale sur ce sujet élargit les définitions de l’architecture islamique, intègre la culture matérielle domestique dans l’histoire des sites liturgiques et érode la distinction présumée entre les contextes religieux et domestique.Article Citation - WoS: 4Investigation of Buildings in Alacati in Terms of Energy Efficiency in Architecture(Konya Technical University Faculty of Architecture and Design, 2020) Avcı, Ali Berkay; Beyhan, Şefika GülinPurpose Due to the depletion of natural resources, energy efficiency in buildings has increasingly gained a major priority. As vernacular houses contain accumulated knowledge to adapt to the climate, they have been crucial examples of energy-efficient architecture for the designers. In this manner, the study focuses on Alacati vernacular houses. The purpose of the study is to investigate and compare the energy-efficient architecture properties of different types of tourism accommodation buildings. Design/Methodology/Approach The accommodation buildings are grouped into three categories, namely Accommodation buildings converted from vernacular houses of the area, New accommodation buildings designed in the style of vernacular houses, and Accommodation buildings that have different architectural styles. Selected three sample buildings from each group are evaluated by energy efficiency principles. Building energy simulation models of the nine case buildings in total are developed to determine the building components' contribution to energy consumption by heating and cooling. The values from energy modeling are used to compare the buildings according to the checklist. Findings According to the results of the study, the density of space, natural ventilation, shading elements, and pitched roof type specialties of vernacular buildings reduce heating and cooling load. However, traditional stone load-bearing walls and bay windows, which are the most significant element of the building form, increase the annual energy demand. At the end of the study, Alacati Energy-Efficient Architecture Database Schema is presented in Table 10 as the outcome of the study. Research Limitations/Implications The evaluation of the case buildings merely depends on the annual cooling and heating energy loads of nine randomly selected buildings. Practical and Social Implications The assessment method used in the study provides the opportunity to identify the proportion of the effect of energy efficiency properties on the total heating and cooling load. Furthermore, the Alacati Energy-Efficient Architecture Schema presented as the ultimate product of this study is expected to guide the architects to design energy-efficient accommodation buildings, without compromising the vernacular architectural appearance of Alacati. Originality/Value The study focuses on the separate effects of the properties of Alacati vernacular architecture, instead of focusing on one property, or comparing case buildings on the energy consumption.Article Citation - WoS: 8Hybrid-Model Simulations To Equilibrate Energy Demand and Daylight Autonomy as a Function of Window-To Ratio and Orientation for a Perimeter Office in Izmir(2020) Baş, Hakan; Kazanasmaz, Zehra TuğçeThis study is based on integrated thermal-lighting simulations to find the optimal value of the window-to-wall ratio (WWR) for a pe?rimeter, single-zone office to equilibrate daylight autonomy and overall energy demand in the climate of Izmir, Turkey. A hybrid model approach has been adopted that combines thermal and lighting calculations in a single model via the IES <VE> software. The optimal WWRs to achieve the highest possible daylight benefit and lowest overall energy use at the same time has been found to have 30% WWR in the South and West, 40% WWR in the East and 60% WWR in the North. These WWR values trade-off daylight benefit, total energy consumption for lighting, heating, and cooling, and visual comfort compared to larger and smaller WWR options. Since the daylight use can significantly reduce artificial lighting energy consumption as long as WWR increases, the energy benefit from lighting reaches 79% as a function of daylight for the South case at 30% optimal WWR. The strongest effect of cooling demand is evident in the breakdown of energy consumption and the amount of glazing is the dominant factor defining the cooling demand. The implications of this study can help architects get feedback on how to save energy for each final energy use (heating, cooling, and lighting) reduction in window space and convey this message to their designs with suggested optimal WWR valuesArticle Citation - WoS: 7İşlev değişikliğinin tarihi yapılar üzerine etkileri “Alsancak Levanten Evleri örneği”(Yıldız Teknik Üniversitesi, 2015) Gazi Gezgin, Aylin; Boduroğlu, ElvinSocial change brings with it new human needs and activities, and in every era humans create and recreate spaces, and hence structures, according to these needs and activities. This means that structures, and their parts, need to undergo change in terms of space and function to adapt to different functionalities and conditions. One understanding of preservation is based on the idea that with a change in function, historical structures which have outlived their original purpose are given new life and once again are made part of the urban landscape. Instances of functional change are most often seen in monumental and historical industrial structures, and in the examples of civil architecture remaining in areas set aside for housing settlements as a result of rapid urbanization. It is important, however, that any functional change made to a historical structure serves to protect the architectural value, meaning and memory of the structure. Alsancak is home to a large number of historical Levantine houses, many of which, following rapid urbanization in the 1970s, have had to change their function to that of bar or cafe. The main purpose of this study was to evaluate the effect of the re-functioning on these houses in Alsancak, and to make some recommendations on both the processes involved in re-functioning, and on the current legal regulations governing these processes with a view to ameliorating the negative effects of re-functioning on such structures.Article Citation - WoS: 1Hafıza Kutusu: Bir Kentsel Kolektif Bellek Deneyi(mi)(Yıldız Teknik Üniversitesi, 2017) Doğu, Tuba; Varkal Deligöz, MelisKentsel tasarımda kullanıcı katılımına verilen önem son yıllarda tüm dünyada artış göstermektedir.
