Conference Object Rethinking Natural Ventilation Strategies in Buildings Through Simulation(International Building Performance Simulation Association, 2023) Coşar, M.; Harputlugil, G.U.; De Wilde, P.Natural ventilation using passive approaches can increase indoor air quality without the need for mechanical systems. In the paper, mechanical ventilation has been ignored due to the associated energy use and greenhouse gas emissions. Instead, the study focusses on natural ventilation that can be created with architectural solutions. Specifically, the indoor air quality of a typical office building in Ankara, Türkiye was determined based on measurements, a building occupant survey, and the natural ventilation conditions as well as design alternatives were analysed by modelling and simulating the building using Autodesk CFD. From the simulation results, it was understood that current form of windows were not found suitable for effective and sufficient natural ventilation. As a result, not only design strategies that will increase the natural ventilation potential are put forward, but also strategies for façade elements have been produced in means of wind catchers. © 2023 IBPSA.All rights reserved.Article Citation - WoS: 2Citation - Scopus: 1A Simple Selection Method of PV Systems for University Campuses(Gazi Univ, 2023) Harputlugil, Gülsu Ulukavak; Bara, Marıam; Ulukavak Harputlugil, GulsuThis paper briefly outlines part of the research work being carried out on the application of the photovoltaic systems to cover universities’ electrical energy needs, with due consideration to the technical, architectural, economic, social. and legal aspects and impacts of this application. The paper considers optimizing the PV system selection objectives and methodology with a case study application. at a university campus in Ankara, Turkey. The main objective here is to develop a practical simple method of selecting an optimum PV system that gives the maximum energy yield possible in a certain period of one year, with the minimum specific energy cost per kWh, where a multiple-variable multi-criteria decision-making making method is applied, to help designers and system engineers in selecting the optimum system. The developed method is demonstrated in the example of the typical case, where the recommended PV system was turned out to be at an Azmuth angle of 0 degrees, the PV technology was monocrystelline Silicon, the annual electrical energy yield per 100 m2 of PV modules surface area 22.4 MWH/Year, the specific electrical energy cost was 0.15 Euos/Kwh, as a first merit option, making a difference of around 13% of saving compared with the 10th last option. The work concludes that a viable PV application is feasible, encouraging its application in various campuses provided that comprehensive planning and careful considerations are given to the related aspects.Article Citation - WoS: 15Citation - Scopus: 16Reflections on the Evidentiary Basis of Indoor Air Quality Standards(Mdpi, 2022) Mahdavi, Ardeshir; Azar, Elie; Bandurski, Karol; Bourikas, Leonidas; Harputlugil, Timucin; Schweiker, Marcel; Berger, ChristianeBuildings are expected to provide healthy and comfortable indoor environmental conditions for their users. Such conditions have diverse dimensions, including thermal, visual, air quality, auditory, and olfactory aspects. Indoor environmental quality standards, guidelines, and codes typically inform professionals in the building design and operation phase in view of procedural, contractual, and legal boundary conditions. Given this critical role of standards, it seems significant to examine the applicability and scientific validity on a regular basis. In this context, the present paper focuses on the standard-based definition of indoor air quality (IAQ) indicators and their respective values. Hence, the main aim of this effort is to study several common national and international IAQ standards in view of the scope to which they include direct or indirect evidence for the validity and applicability of their mandates and requirements. To this end, selected IAQ standards were assessed via a structured schema that includes not only basic information, quality indicators, and suggested and recommended value ranges, but also any reference to scientific studies. The findings of this effort identify certain issues with the transparency of the chain of evidence from the results of technical literature and standard-based IAQ recommendations. Moreover, recommendations are made for the development of future transparent and evidence-based IAQ standards and guidelines.Article Occupational Health and Safety in Construction Industry with Vision Zero Approach(2022) Doğan Karaman, Gülşah; Er Akan, AslıSafety is one of the major issues for the construction industry which is a dangerous sector with fatality statistics. There are thousands of construction accidents all over the world that are the direct result of hazardous activities and working conditions. Safety management systems and policies are the key elements in order to increase safety awareness, improve working conditions, reduce human suffering, provide safety climate and culture etc. In this context, the Zero Accident Vision (ZAV) is a new approach that is founded on the premise that all accidents may be avoided. This review explores relationships between ZAV and construction safety with the aim of fostering further researchArticle Citation - WoS: 3Structural Behaviour of 13th and 14th Century Seljuk Mosques and Acculturation of Construction Knowledge(Univ Zagreb Fac Architecture, 2022) Akan, Asli ErThis study aims to demonstrate the acculturation of Seljuk architecture and construction techniques by tracing the development of peripheral walls in Seljuk wooden hypostyle mosques built in 13th and 14th centuries. To track the exchange of construction knowledge two Seljuk mosques (the Hanonu Mosque in Kastamonu and the Ahi Elvan Mosque in Ankara) are selected for comparison in this study. The main difference between the two mosques is their structural systems: one has a wooden peripheral wall and wooden skeleton system, while the other has a masonry peripheral wall and wooden pillars. In this study, a comparison of the structural systems and performances of these examples of wooden mosques exhibiting different wall systems was made together with structural analyses under basic loads. A series of structural analyses provides significant data about the structural behaviour of these types of structures, indicating acculturation of elements from Asia and Byzantium within Seljuk architecture and construction techniques.Article Increasing Social Awareness and Professional Collaboration in Architectural Education Towards a Sustainable and Disaster-Free Future(2013) Özmen, CengizThe aim of this study is to explore ways of increasing the social and professional awareness of students of architecture to educate a new generation of architects who are familiar with the concepts of social responsibility, professional collaboration, sustainable development and disaster mitigation. Turkey experiences a rapid social change due to the urban regeneration, population movements, environmental changes, new technologies and professional diversification. These phenomenon affect all aspects of life. This study explores the possibilities for applying new methods of teaching in schools of architecture to train a generation of architects who will be in tune with this new, ever-changing socio-cultural environment in Turkey. A study lasting one educational term of 14 weeks was conducted on a group of 15 second year students of architecture. A structural design course which previously had a purely theoretical and mathematical approcah to the subject matter was altered to contain background information regarding social context such as the photos, videos and narratives of earthquake affected areas of Turkey. This was done to introduce the students with the reality of the built environment and professional life in Turkey. Additionally small-scale applied projects were given as semester tasks to the students where they can experience a scaled but realistic application of the theoretical knowledge into reality. These two approaches were supplemented with theoretical knowledge to prepare the students for professional life in a realistic manner. A sudden increase in student attention and participation to the course was observed both in matters concrening the professional application and social context of their architectural projects. These findings were consistent with a previous study conducted by the author. The findings of this experimental application have resulted in a revision of the educational curriculum concerning the structural design courses to permanently include information regarding the social context and practical application of theoretical projetcs.Article Impact of Glazing on Thermal Comfort, Relative Humidity, and Lighting Level in Office Spaces(2018) Özkan Öztürk, NurProviding a working environment that has certain level of comfort is one of the most prominent requirement of an office space. Clearly, relevant space parameters are necessary to perform minimum space quality. In this regard, building components that have an impact on indoor environmental quality (IEQ) are so critical that can change the quality of the place in a critical extent. Even if the buildings are typical and orientation is the same, comfort conditions could be different. Furthermore, facade configuration of a building has an impact on space comfort. Glazing of an office space can affect the comfort conditions in terms of temperature, relative humidity and light intensity. For this purpose, three typical office spaces in Mustafa Kemal neighborhood in Ankara are studied as a case and examined in terms of environmental conditions of interior.Article An Architectural Reading of Zamyatin’s Intersectional Elements in the Novel “we”(2021) Çavdar, Rabia Çiğdem“We” was written by Russian novelist Yevgeny Zamyatin in 1921 after the Soviet Revolution. To be at the edge of the conflicts was scrutinized at the novel, in which the protagonist, labeled as D-503, having a tentative position at the well-defined ground by the power which presented itself as the truth or the law. The narration was constructed via the diary of protagonist; how D-503 perceived the paradigm, which he had lived in, what kind of conflicts and contradictions he had been living with the system was questioned. Zamyatin chose very specific architectural elements to explain and criticize the dominant paradigm of the era -early 1920’s, and the periphery of that dominancy; like Green Wall, Glass Wall, logical labyrinth, cube square, and etc. These intersectional elements were constructed as in the form of blurred voids in order to unfold the ideological positions of the written period of the novel. The materialization and meaning of the walls, could be read as dialectic conceiving of how Zamyatin scrutinized both the revolution and the paradigm. As being a dystopia, the novel “We” criticizes the idealized beliefs that were presented as transparent, lucid and conductive.Article Citation - WoS: 3Citation - Scopus: 4Towards an Earthquake-Resistant Architectural Design With the Image Classification Method(Taylor & Francis Ltd, 2024) Akan, Asli Er; Bingol, Kaan; Ormecioglu, Hilal Tugba; Er, Arzu; Ormecioglu, Tevfik Oguz; Er Akan, AslıArchitectural design is an interdisciplinary process which involves multiple stages that are interconnected. In this process, it is common for major decisions to be changed during the final stage, the analysis of the structural system. After making substantial corrections, the architect has to revisit the early stages, the preliminary project. This back-and-forth process can result in significant losses in time and cost. The proposed Irregularity Control Assistant (IC-Assistant) aims to provide architects with feedback on the conformity of structural system decisions to the irregularities defined in the Turkish Building Earthquake Code (TBEC-2018), using image processing methods at the early stages of the design process. The IC-Assistant was preliminarily created to evaluate the torsional irregularity of plan organization using deep learning methods. In this study, the results of the IC-Assistant were verified by structural analysis with the Prota-Structure program. The novelty of this study is the use of the image-classification method in earthquake-resistant architectural design. Up to this point, the method has been mainly used in facial recognition systems. This method minimizes time, human error, and cost losses and includes awareness of load bearing and earthquake resistance as inputs in the early stages of architectural design.Article Citation - WoS: 10Citation - Scopus: 11Post-Restoration Seismic Performance Assessment of a Historic Hypostyle Mosque in Anatolia (13th Century Ad)(Elsevier, 2023) Cosgun, Turgay; Akan, Asli Er; Uzdil, Oguz; Er, Arzu; Ormecioglu, Hilal Tugba; Sayin, BarisAssessment of structural performance under seismic effects is a very important step for restoration process of historic buildings that represent construction techniques and material characteristics of their era. This process consists of three stages namely, on-site examinations, restoration practices, and seismic analysis, and therefore, requires a multidisciplinary approach. Hypostyle structures are mostly timber-framed buildings with masonry walls on two or three facades. This construction method is a combination of Asia (wooden pillar) and Byzantine (masonry walls) techniques. The primary load-bearing system in these buildings is composed of multiple rows of wooden pillars. This paper presents post-restoration seismic assessment of a historic wooden hypostyle mosque complex constructed in 1273. This mosque complex is an important structure representing wooden hypostyle architecture in the Anatolia region of Turkey and is composed of three separate structures namely, a main mosque building, a minaret, and a tomb. Linear performance analysis, displacement-controlled nonlinear analysis, and kinematic limit analysis for failure mechanisms were conducted for the structures after the restoration. The linear performance analysis results indicated that the structures meet shear strength requirements for DD3 and DD2 earthquakes with recurrence periods of 72 and 475 years, respectively. Furthermore, according to the linear and non-linear analyses, the complex was found to satisfy performance limits for both ground motion levels in terms of inter-story drifts.
