    Challenges in synchronous e-learning in architectural education
    (Springer, 2021) Altıntaş Kaptan, M.; Edis, E.; Ünlü, Gülten Aslıhan; Architecture; ÜNLÜ, Gülten Aslıhan
    Distance learning is a centuries-old method, from first correspondence courses to educational broadcasting. It eventually evolved into e-learning, where the acquisition of knowledge is managed via electronic media and nowadays, the Internet became the prominent medium for information delivery. The use of internet technology and applications allowed two-way communication between students/audience and lecturer/presenter, either simultaneously, or with a time-lag. Despite its long-standing history, e-learning methods still preserve their novelty in terms of changing the traditional ways of face-to-face learning methods in which both lecturer and audience are considerably much familiar with. In an Erasmus + partnership project titled Re-use of Modernist Buildings (RMB), the use of both synchronous and asynchronous e-learning methods was concerted within the context of a joint master’s programme that is planned to be established by the partner universities. Concerning the decision to employ e-learning, some synchronous seminar and lecture sessions were tried and tested both during an RMB project workshop and within other university courses. A survey was conducted after each session in order to understand students’ opinions on e-learning in comparison with traditional classroom learning. In this paper, open-ended responses collected through the survey are examined in detail, and comparative analysis of personal opinions and comments in relation to certain Likert scale questions are reported in order to review and discuss participants’ perspective on the synchronous e-learning session attended. In this respect, a brief introduction regarding the RMB project and e-learning is provided primarily, followed by the synchronous session cases and evaluation method, and finally, the findings are presented and discussed with examples.

    Assessment of synchronous online architecture education from students’ perspective
    (Anadolu University, 2023-10) Kaptan, M. A.; Edis, E.; Ünlü, Gülten Aslıhan; Architecture; ÜNLÜ, Gülten Aslıhan
    This research aims to identify and investigate different dimensions and underlying factors influencing the successful implementation of e-Learning, from participants' viewpoint, i.e. architecture students. To examine the constituents ofan effective e-Learning experience in education, evaluation themes were formulated as overall substitutability level, cognitive performance, social interaction and engagement, student comprehension and comfort, personal preference, and learners' satisfaction. Through literature survey and review of mostly referred factors affecting e-Learning efficiency, four dimensions were designated for further elaboration in this study: (i) course characteristics, (ii) participant characteristics, (iii) e-Learning environment, and (iv) prior acquaintance, with each category including several sub-measures. Survey method was employed and a questionnaire was administered to 122 architecture students at both undergraduate and graduate levels to investigate participant perspectives in reference to particular synchronous lectures delivered online. Out of ten potential influencing factors hypothesized, seven were verified to be critical determinants of e-Learning effectiveness in architectural education.

    Towards a human centred approach for adaptive façades an overview of user experiences in work environments
    (TU Delft, 2022) Koyaz, M.; Prieto, A.; Ünlü, Gülten Aslıhan; Knaack, U.; Architecture; ÜNLÜ, Gülten Aslıhan
    Adaptive façades are multifunctional systems that are able to change their functions, features, or behaviour over time in response to changing boundary conditions or performance requirements. As one of the significant developments in the façade industry over the last decade, the adaptive façade offers an intelligent solution that can decrease energy consumption and potentially increase users’ comfort in a building. From an engineering perspective, these advanced technologies aim to improve the overall performance of the building while generating a better indoor environment for the users, but unfortunately, investigations show that this goal is not always achieved. This is why, to bridge this performance gap, we embark on a change of perspective in façade design, from a technology-centred to a human-centred one. This research emphasizes that, with their changeability aspects, adaptive façade technologies offer unique potential, although the design of such façades requires a deeper understanding of users. With this as its focus, this paper aims to identify the factors affecting the user experience in a working environment, considering the interactions of the user with building services and façade systems from a holistic point of view, in which façade-user relationships are to be distinguished, towards the larger aim of developing a human-centred approach for adaptive façade design.

    Human-centred performance criteria for adaptive façade design: Based on the results of a user experience survey
    (Elsevier, 2022-08-15) Koyaz, M.; Ünlü, Gülten Aslıhan; Architecture; ÜNLÜ, Gülten Aslıhan
    Indoor environmental conditions have significant effects on the user, in terms of comfort, satisfaction, and well-being. Even though the façade is one of the main systems that shape the indoor environment, there is a lack of research on how it affects the user. In work environments, not only indoor conditions but also the daily interactions with the building's façade (i.e. opening a window, closing a window blind, or simply looking through a window) have a consequential impact on the user experience. In that respect, as a part of ongoing doctoral research, an international online survey study was conducted to investigate users' experiences in their work environments, related to the building's façade. The questionnaire was structured not only to understand the users' current experiences but also their anticipations in terms of a preferred user experience concept. Hence, portrays a perspective on the question: what do users want from the façade that they are interacting with, in work environments? This paper primarily presents the effects of the human factors on the preference levels of different user experiences and interpretation of the results leads to the determination of human-centred performance criteria for adaptive façade design.

    Multi-criteria performance evaluation of a glass panel system using full-scale experimental data
    (Taylor & Francis, 2020-11-01) Ilter, E.; Celik, O. C.; Ünlü, Gülten Aslıhan; Architecture; ÜNLÜ, Gülten Aslıhan
    In order to better evaluate the lifetime performance of glass panel facade systems, this study firstly proposes to conduct a full-scale wind resistance, air/water infiltration, and seismic resistance tests. Two specimens were designed, constructed, and tested for this purpose. A fatigue process is also applied to one of the manufactured systems in addition to a standard test procedure. Secondly, data acquired from the experimental part of this work have been used in a multi-criteria performance evaluation process to determine the performance levels of each of the specimens. In the evaluation process, a total of 10 different criteria and 2 alternatives are identified for decision making. Performance indicator data obtained from the detailed calculations using the AHP (Analytic Hierarchy Process), COPRAS (Complex Proportional Assessment) and TOPSIS (The Technique for Order of Preference by Similarity to Ideal Solution) methods are then utilized during the numerical assessment process. The 'criticality level' is defined within the evaluation process and it indicates the percent (%) values of the obtained performance indicators. As a result of the performance evaluations, the AHP and TOPSIS methods gave similar results and could be selected as the preferred methods for the evaluation of such experimental data. Results obtained from the AHP and TOPSIS methods are consistent and easy to interpret when compared to the COPRAS method. Furthermore, in this work, the most critical criterion is found to be the frontal deflections.
