Article Citation - WoS: 1On-Site Measurements of Temperature and Humidity Conditions for the Comparison of Urban and Rural Sub-Spaces of Traditional Settlements: Historical City of Mugla, Turkey(Taylor & Francis, 2023) Timur, Barış Ali; Başaran, Tahsin; İpekoğlu, BaşakOne of the significant processes that ensures realistic determination of the energy needs of historical buildings is case-specific definition of their local microclimatic conditions. Accordingly, the aim of this study is to determine differences for the parameters of temperature and humidity in urban and rural sub-settlements of the historical city, Mugla/Turkey. Study method consists of on-site measurements of these variables in sub-settlements for comparisons. As a result, it was identified urban zone shows heat island characteristics with warmer, drier, and more stable conditions; while rural sub-settlement remains cooler, more humid, and more erratic. In parallel, calculated extents of these differences demonstrate the significance and necessity of on-site measurements and consequential microclimatic zoning of historical cities as conservation/planning tools for responding to the thermal needs of architectural heritage. A key application of these processes would be the establishment of local databases of case-specific weather data to be used in thermal simulation assessments.Article Citation - WoS: 77Citation - Scopus: 95Thermal, Daylight, and Energy Potential of Building-Integrated Photovoltaic (bipv) Systems: a Comprehensive Review of Effects and Developments(Elsevier, 2023) Taşer, Aybüke; Kundakçı Koyunbaba, Başak; Kazanasmaz, Zehra TuğçeAccording to energy consumption data of the European Union, buildings account for 40 % of overall energy consumption in all sectors. The rise in building energy demand seriously affects global warming. To reduce demand, buildings must be designed to be energy-efficient. As part of energy-efficiency initiatives, unique systems that employ renewable energy sources should be implemented in buildings. As a new technology, building-integrated photovoltaics is considered an essential technology to achieve this target. Several variables affect the thermal, daylight, and energy performance of building-integrated photovoltaic systems; related to environmental and photovoltaic-related parameters. Thus, the challenges and effects of these variables on the overall performance of these systems should be investigated. This research analyzes building-integrated photovoltaic implemented studies and presents a state-of-art review of recent developments. The study not only summarizes the existing studies developed in this field so far but also analyzes the variables and makes concrete generalizations and inferences. It enables finding gaps and deficiencies in the literature and provides a better understanding of all the variables that affect the performance of building-integrated photovoltaic systems by interpreting the results in detail and representing them graphically instead of only through textual analysis. Results show that building-integrated photovoltaics contribute to constructing a sustainable future for cities. Developments in this industry motivate researchers in this field, whose work will make it easier to cope with future ecological challenges. It helps to build a more sustainable future for society. With new developments, it will be possible to mitigate the effects of future environmental problems.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: 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)Article Citation - WoS: 13Citation - Scopus: 15The Spatial Configuration and Publicness of the University Campus: Interaction, Discovery, and Display on De Uithof in Utrecht(Palgrave Macmillan Ltd., 2022) Yaylalı Yıldız, Berna; Spierings, Bas; Çil, ElaThis paper explores different degrees and forms of publicness and their relationship with the spatial configuration of a university campus. Based on a literature review, the concept of 'publicness' is developed to describe the dimensions of 'interaction,' 'discovery,' and 'display' on campus. The area selected for the case study is De Uithof campus of Utrecht University, located outside the urban fabric in a green environment. Spatial configuration analysis reveals that the two public spaces most-often used by students have high global and local integration scores as well as medium visibility scores. This promises much potential for the production of publicness in both spaces, whereas student surveys revealed some rather substantial differences in publicness between them. Acknowledging detailed differences in terms of physical design, functional facilities, and social composition enables an explanation for why the Academic Hospital Utrecht space lives up more the potential of publicness production than the Heidelberglaan space.Article Citation - WoS: 21Citation - Scopus: 27Exploring the Impact of External Shading System on Cognitive Task Performance, Alertness and Visual Comfort in a Daylit Workplace Environment(SAGE Publications Inc., 2019) Leccese, F.; Salvodori, G.; Öner, Merve; Kazanasmaz, Zehra TuğçeThe authors examined the effect of external shading system on cognitive performance, alertness and visual comfort of visual display terminal (VDT) users under two realistic office lighting settings in this study. Daylight was the source of illumination being considered as the most significant and preferred one. A total of 26 participants performed visual and cognitive demanding tasks as well as providing subjective alertness, performance and visual evaluations in a full-scale mock-up VDT workstation. Two trials (with and without shading system) were executed during one experimental session. Results revealed that the use of a shading system improves the performance of a user on colour-naming task requiring sustained attention, while no differential effects were observed on tasks involving other cognitive skills such as search velocity and vigilance. Within-subject performance differences were more pronounced during morning hours. Higher performance was reported in some cognitive tests when the subjective sensation of visual discomfort was lower.Article Citation - WoS: 7Citation - Scopus: 9Fuzzy Logic Model for the Categorization of Manual Lighting Control Behaviour Patterns Based on Daylight Illuminance and Interior Layout(SAGE Publications Inc., 2019) Cılasun Kunduracı, Arzu; Kazanasmaz, Zehra TuğçeIn considering total building energy consumption, lighting plays an important role in shaping energy consumption and use. Although key strategies (such as energy efficient lighting products, lighting control systems and energy simulation software) are developed so far, such attempts may be unsuccessful unless users are not taken into consideration. Users’ behaviours and their manual lighting control actions depend on various factors, though within the scope of this study manual lighting control behaviour was analysed only in terms of interior layout and daylight illuminance. Three private offices in Izmir Institute of Technology were monitored using illuminance metres and occupancy/light detectors under eight different interior layout conditions. In relation to change of interior layout and daylight penetrations, users’ manual lighting control behaviours were monitored. The obtained data were then used to construct a fuzzy logic model in MATLAB FIS editor. A fuzzy logic algorithm was applied to classify behaviour patterns about the tendency to turn on the lights. This kind of prediction of the light usage tendency regarding the occupancy is aimed to foresee the ‘possible’ manual lighting control behaviour within given conditions. The gathered classification can be used further in future studies of manual lighting control behaviour and energy-saving estimations/simulations.Article Citation - WoS: 11Citation - Scopus: 10Assessment of Construction Techniques and Material Usage in Izmir Rural Houses(Taylor and Francis Ltd., 2015) Tunçoku, Selim Sarp; İnceköse, Ülkü; Akış, Tonguç; Yalçın, Mehmet AliThe domestic architecture in the rural villages of ̄zmir comprises a unique built environment with their masonry wall textures, semi-open sofas, round tiled-hipped roofs, and chimneys, and represents an important part of the cultural and architectural heritage. This assessment is mainly based on field observations that focus on the architectural and structural layout of intact, damaged, and destroyed houses. During field observation and the analysis of data certain plan typologies and relationships between the geological formations of the region and choice of materials and construction techniques were observed. While load-bearing masonry and timber skeleton systems are common, extensive use of timber laces, stone, and fired or adobe brick masonry with mud mortar and timber frames infilled with masonry materials were frequently seen. Generally, round timber elements such as wall plates, laces, lintels, posts, and frames of flooring systems are used. Architectural degenerations in authentic houses, defective details and partially due to the earthquake-prone nature of the region seismicity have been evaluated. An overall approach for the preservation and sustainability of this heritage is suggested.Article Citation - WoS: 14Citation - Scopus: 20Exploring the Effects of Spatial and Social Segregation in University Campuses, Iztech as a Case Study(Palgrave Macmillan Ltd., 2014) Yaylalı Yıldız, Berna; Yamu, Claudia; Çil, ElaThis study focuses on the spatial configuration of university campuses through the case study of Izmir Institute of Technology (IZTECH), settled outside of the city of Izmir. Isolated university campuses are interesting cases to examine, especially when there is a need to focus on the relationship between the campus life and collective spaces, in which open spaces play a major role. Although these campuses are planned as separate enclaves with the vision that academic life would require isolation, quietness and concentration, we argue that the campus design, especially their open spaces, should generate an interacting community balancing the inward-focused learning. In addition, we suggest that when a university campus fails to facilitate social gatherings through its spaces, both faculty and students are deprived of the fundamental reason of the university's constitution. This article first presents the spatial analysis (space syntax analysis) examining the potentials of the physical configuration of campus for bringing students together. Second, we present the findings of the questionnaire surveying students' choices for spatial practices. Syntax analysis and survey show that locally integrated lines are not supported with activities. Comparison of the frequency of use in actual practice both on the most integrated lines and on areas with strong visibility show that these spaces are not lived up to their potentials.

This study aims to develop criteria for the evaluation of reconstructions at archaeological sites. The criteria have been developed through review of current international and national conservation charters to help improve reconstruction proposals. These criteria are determined considering the remain scale and the site scale. Accuracy of the reconstruction, avoidance of physical damage, compatibility of materials, distinguishability of the interventions, availability of the interventions for future applications, and reversibility are the criteria concerning the remain scale; limits of the intervention, retainability of the original characteristics of the site, and perception of the reconstruction are the criteria concerning the site scale. These criteria are applied to the reconstruction works realized at the West Stoa of Agora, zmir, Turkey during 1930s, which had to be dismissed and reimplemented in 2000s. The recent reconstruction was applied with compatible materials; the interventions did not damage the original materials and they are distinguishable. This study of the reconstruction presents the latest architectural information, provides a basis for future studies, and is reversible. The reconstructed structure does not falsify the original characteristics, but enables increased perception of the site.
