Article Citation - WoS: 7Citation - Scopus: 8Integrating Building and Context Information for Automated Zoning Code Checking: a Review(International Council for Research and Innovation in Building and Construction, 2022) Demir Altıntaş, Yelin; İlal, Mustafa EmreInteroperability approaches have attracted much attention in the AEC/FM industry with the increased interest in Building Information Modeling (BIM) studies since 2000's. Especially, the integration of BIM with GIS is crucial for areas, which need detailed information on buildings and their surroundings. Automated code compliance checking against zoning codes is an area that requires both zoning data and building design data. In an ideal automated zoning code checking process, building codes should be retrieved from the responsible authority, data regarding the neighborhood the project is located in should be retrieved directly from the local municipality's GIS, and the building project should be supplied by the designer as a BIM file. The checking process should be able to work with a combination of GIS and BIM data and generate a compliance report. Although recent BIM-GIS integration efforts have been successful in some areas, BIM-GIS integration studies in the context of automated zoning code compliance checking are limited, and the data interoperability problem in this field still needs to be addressed. This paper intends to (1) provide a critical review and analysis of the current BIM and GIS integration studies for building permit processes, (2) present the opportunities that the implementation of integrating BIM and GIS might bring to the automated zoning compliance checking domain and (3) identify promising integration approaches for future efforts.Article Citation - WoS: 4Citation - Scopus: 5An Evaluation of the Relationship Between Everyday Life Rhythms and Urban Morphology: the Square of Bursa Kent Meydani Shopping Center, Turkey(SAGE Publications, 2022) Gümüş, İmran; Yılmaz, EbruThe aim of this study is to search for the relationship between the morphological character of urban space and the rhythms of everyday life. Initially, behavioral maps are created by observing daily life rhythms, video recordings are taken on weekend and weekday, the snapshot technique, video recordings, and the pedestrian count analysis are used. In the second step, morphological analyses of the study area are prepared by using space syntax approach. Connectivity, local, and global integration values are obtained through creating axial map, and, in addition, visibility graph analysis (VGA) is performed. Bursa Kent Meydani Shopping Center (BKMSC) consists of a square and the shopping units surrounding it. This area was the main transportation point as Central Bus Station Complex until 2006. The area was selected within the scope of the study because its changing public use due to the functional transformation of the area plays a significant role in the identity of the Bursa. The behavioral maps obtained from the observational data give information about user mobility, various actions, and the activities' locations on weekends and weekdays. By correlating and comparing behavioral and space syntax maps analyses, the relationship between the rhythmic character and the morphological structure of the urban space is tested. The study presents original data by revealing the effects of the morphological elements of Bursa on the daily rhythms of the square of BKMSC. The case study is limited to the surveys conducted in 2 days and three different times of the day. The relationship between observational data and space syntax data shows that daily life rhythms are not independent of the morphological factors.Article Citation - WoS: 5Citation - Scopus: 5Loop Based Classification of Planar Scissor Linkages(Springer, 2022) Kiper, Gökhan; Korkmaz, Koray; Gür, Şebnem; Yar Uncu, Müjde; Maden, Feray; Akgün, Yenal; Karagöz, CevahirScissor linkages have been used for several applications since ancient Greeks and Romans. In addition to simple scissor linkages with straight rods, linkages with angulated elements have been introduced in the last decades. In the related literature, two methods have been used to design scissor linkages, one of which is based on scissor elements, and the other is based on assembling loops. This study presents a systematic classification of scissor linkages as assemblies of rhombus, kite, dart, parallelogram and anti-parallelogram loops using frieze patterns and long-short diagonal connections. After the loops are replicated along a curve as a pattern, the linkages are obtained by selection of proper common link sections for adjacent loops. The resulting linkages are analyzed for their motions and they are classified as realizing scaling deployable, angular deployable or transformable motion. Some of the linkages obtained are novel. Totally 10 scalable deployable, 1 angular deployable and 8 transformable scissor linkages are listed. Designers in architecture and engineering can use this list of linkages as a library of scissor linkage topologies.Article Citation - WoS: 27Citation - Scopus: 34Multi-Zone Optimisation of High-Rise Buildings Using Artificial Intelligence for Sustainable Metropolises. Part 2: Optimisation Problems, Algorithms, Results, and Method Validation(Pergamon-Elsevier Science LTD, 2021) Ekici, Berk; Kazanasmaz, Zehra Tuğçe; Turrin, Michela; Taşgetiren, M. Fatih; Sarıyıldız, I. SevilHigh-rise building optimisation is becoming increasingly relevant owing to global population growth and urbanisation trends. Previous studies have demonstrated the potential of high-rise optimisation but have been focused on the use of the parameters of single floors for the entire design; thus, the differences related to the impact of the dense surroundings are not taken into consideration. Part 1 of this study presents a multi-zone optimisation (MUZO) methodology and surrogate models (SMs), which provide a swift and accurate prediction for the entire building design; hence, the SMs can be used for optimisation processes. Owing to the high number of parameters involved in the design process, the optimisation task remains challenging. This paper presents how MUZO can cope with an enormous number of parameters to optimise the entire design of high-rise buildings using three algorithms with an adaptive penalty function. Two design scenarios are considered for quad-grid and diagrid shading devices, glazing type, and building-shape parameters using the setup, and the SMs developed in part 1. The optimisation part of the MUZO methodology reported satisfactory results for spatial daylight autonomy and annual sunlight exposure by meeting the Leadership in Energy and Environmental Design standards in 19 of 20 optimisation problems. To validate the impact of the methodology, optimised designs were compared with 8748 and 5832 typical quad-grid and diagrid scenarios, respectively, using the same design parameters for all floor levels. The findings indicate that the MUZO methodology provides significant improvements in the optimisation of high-rise buildings in dense urban areas.Article Citation - WoS: 14Citation - Scopus: 17Experimental Investigation on Heat Transfer and Air Flow Behavior of Latent Heat Storage Unit in a Facade Integrated Ventilation System(Elsevier Ltd, 2021) Pekdogan,T.; Tokuç,A.; Ezan,M.A.; Başaran,T.All-air central HVAC systems are widely applied to provide fresh and conditioned air, which is very important for users to lead healthy and productive lives. Decentralized systems are another mechanical solution to ensure indoor air quality and thermal comfort with a heat recovery ventilation system integrated into the building wall. These commercially available systems store sensible energy in the heat exchanger. In this study, an experimental real-size staggered tube bundled prototype with phase change material (PCM), which stores latent thermal energy, was proposed/designed and full-scale experiments were carried out in laboratory conditions. The experimental setup includes two spaces that simulate indoor and outdoor conditions that are separated by an insulated aerated concrete wall. In the prototype, two ducts embedded in the wall contain staggered tube bundles filled with PCM, which are positioned perpendicular to the airflow to recover heat for supply and exhaust ventilation modes. The thermal performance of this prototype is investigated for different operating times, namely, 15, 20, and 30 min. The average air energy change of the latent heat recovery ventilation system values is between 20 and 35 kJ approximately for the operating times. The supply mode efficiency result is an average of 50% and exhaust mode efficiency is 25%. © 2021 Elsevier LtdArticle Citation - WoS: 38Citation - Scopus: 50Multi-Zone Optimisation of High-Rise Buildings Using Artificial Intelligence for Sustainable Metropolises. Part 1: Background, Methodology, Setup, and Machine Learning Results(Elsevier Ltd., 2021) Ekici, Berk; Kazanasmaz, Zehra Tuğçe; Turrin, Michela; Taşgetiren, M. Fatih; Sarıyıldız, I. SevilDesigning high-rise buildings is one of the complex tasks of architecture because it involves interdisciplinary performance aspects in the conceptual phase. The necessity for sustainable high-rise buildings has increased owing to the demand for metropolises based on population growth and urbanisation trends. Although artificial intelligence (AI) techniques support swift decision-making when addressing multiple performance aspects related to sustainable buildings, previous studies only examined single floors because modelling and optimising the entire building requires extensive computational time. However, different floor levels require various design decisions because of the performance variances between the ground and sky levels of high-rises in dense urban districts. This paper presents a multi-zone optimisation (MUZO) methodology to support decision-making for an entire high-rise building considering multiple floor levels and performance aspects. The proposed methodology includes parametric modelling and simulations of high-rise buildings, as well as machine learning and optimisation as AI methods. The specific setup focuses on the quad-grid and diagrid shading devices using two daylight metrics of LEED: spatial daylight autonomy and annual sunlight exposure. The parametric model generated samples to develop surrogate models using an artificial neural network. The results of 40 surrogate models indicated that the machine learning part of the MUZO methodology can report very high prediction accuracies for 31 models and high accuracies for six quad-grid and three diagrid models. The findings indicate that the MUZO can be an important part of designing high-rises in metropolises while predicting multiple performance aspects related to sustainable buildings during the conceptual design phase. © 2021 The Author(s)Editorial How Doorknob Gets Its Meaning(Routledge, 2005) Doğan, Fehmi; Nersessian, Nancy J.Jerry Fodor’s (1998) Concepts: Where Cognitive Science Went Wrong (hereafter referred to as Concepts) and Geoffrey C. Bowker and Susan Leigh Star’s (1999) Sorting Things Out: Classification and its Consequences (hereafter referred to as Sorting) represent orthogonal views of concepts and categories stemming from two very different philosophical traditions. Fodor focuses on theories of concepts, whereas Bowker and Star discuss what categories and classification systems are. For Fodor, concepts are mental particulars that apply to things in the world (p. 23).Book Review Feminist Practices: Interdisciplinary Approaches To Women in Architecture(Taylor & Francis, 2012) Yücel, ŞebnemFeminist practices: interdisciplinary approaches to women in architecture, edited by Lori A. Brown, 2011, Surrey and Burlington, Ashgate, 378 pp., $65 (hardback), ISBN 978-1-4094-2117-7 Feminist Practices originates from a traveling exhibition and series of public talks with the same name that took place in 2008 and 2009. As the title suggests, the book presents feminist practices and methodologies in architecture. While doing that, however, we are urged to think outside the box. Firstly, ‘feminist’ in feminist practices is not necessarily ‘female focused’ or ‘gender specific’. Rather, it refers to alternative modes of seeing, researching and practicing. Secondly, architecture is also approached critically, opposing the star system, engaging the client and the community, and challenging usual hierarchies: visual/material, permanent/transient, public/private, labored/expedient, and precious/ valueless (325). In return, feminist practices in architecture refers to explorations on all alternative modes of pedagogy, research and practice that establish new ways of understanding spatial relationships, revise existing power relations and offer possibilities for new interactions and value systems. This is a huge task, but a worthy one. However, there is one problem with the title that needs to be recognized.Article Citation - WoS: 61Citation - Scopus: 68Energy and Environmental Performance Based Decision Support Process for Early Design Stages of Residential Buildings Under Climate Change(Elsevier, 2019) Gerçek, Mümine; Arsan, Zeynep DurmuşBuilding design decisions have high impacts on energy and environmental performance of buildings. Especially, conscious decisions in earlier design stages are more significant due to lifespan impact of buildings. Deficiencies in systematic approach for design decision support to increase energy and environmental performance of buildings are projected as the major problems of this study. Decisions for performance-based design should be made in terms of the most effective design parameters peculiar for each project. This study exemplifies the act of design decision support in early design stage of a residential building in Turkey. The relation between design parameters and annual energy consumption for heating, cooling and annual operational CO2 emissions is examined by global sensitivity analyses for the present, 2020s, 2050s and 2080s weather conditions. Design process requires the assessment of the uncertainties in building performance caused both by design parameters and climate change. The results indicate that the decisions about solar heat gain coefficients (SHGC), and heat transfer coefficients (U) of transparent surfaces on building envelope have the highest impacts on energy and environmental performance of residential buildings in hot-humid climatic conditions.Article Citation - WoS: 14Citation - Scopus: 14Photon-Mapping in Climate-Based Daylight Modelling With High-Resolution Bsdfs(Elsevier Ltd., 2019) Grobe, Lars OliverVisual comfort assessments employing luminance-based metrics rely on efficient CBDM techniques for image synthesis. Data-driven BSDF models allow to isolate internal light paths in optically CFS from CBDM. Bidirectional photon mapping is proposed for the efficient sampling of such models in the calculation of the direct solar component in CBDM. The method allows accurate image synthesis for visual comfort assessments with only two calculation steps, achieving comparable accuracy as the established but complex 5PM. The validity of the approach is confirmed by comparison with backward ray-tracing. Its exemplary application to compare two CFS in terms of glare control demonstrates the importance to achieve reconcilability of conflicting targets such as view and glare control in daylighting.
