Data Paper Citation - WoS: 3Citation - Scopus: 4Experimental data showing the thermal behavior of a flat roof with phase change material(Elsevier, 2015) Tokuç, Ayça; Başaran, Tahsin; Yesügey, Sadık CengizThe selection and configuration of building materials for optimal energy efficiency in a building require some assumptions and models for the thermal behavior of the utilized materials. Although the models for many materials can be considered acceptable for simulation and calculation purposes, the work for modeling the real time behavior of phase change materials is still under development. The data given in this article shows the thermal behavior of a flat roof element with a phase change material (PCM) layer. The temperature and energy given to and taken from the building element are reported. In addition the solid-liquid behavior of the PCM is tracked through images. The resulting thermal behavior of the phase change material is discussed and simulated in [1] A. Tokuç, T. Başaran, S.C.

RADIANCE employs the tensor tree to store the BSDF at high directional resolution. Its application in backward ray-tracing is however challenging, since the density of stochastic samples must match the model resolution. BSDF proxy and peak extraction address this problem, but are limited to cases when either the fenestration geometry, or the shape and direction of the transmission peak are known. Photon Mapping is proposed to efficiently sample arbitrary BSDFs from the known sun direction. The existing implementation in RADIANCE is extended to account for light sources and their reflections in the field of view, that are of particular importance for visual comfort assessments. The method achieves a high degree of accordance with ray-tracing, and reduces simulation times by approximate to 95% with data-driven models of high resolution.Article Citation - WoS: 3Citation - Scopus: 6Use of Analogies, Metaphors, and Similes by Students and Reviewers at an Undergraduate Architectural Design Review(Cambridge University Press, 2019) Doğan, Fehmi; Taneri, Batuhan; Erbil, LivanurThis study investigates the use of similarities in the form of analogy, metaphor, and simile by students and reviewers in an undergraduate architectural design review. In contrast to studies conducted in vitro settings, this study emphasizes the importance of studying analogies, metaphors, and similes in a natural setting. All similarity relationships were coded according to their type, the level of expertise, range, frequency, goal, value judgment, and depth. The results indicate that analogies, metaphors, and similes were used spontaneously and without any difficulty by both reviewers and students. Reviewers, however, were almost twice as likely to evoke similarities. Metaphor was the most frequently used similarity relationship among the three. It was found that there was a significant relationship between the level of expertise and type of similarity, with students more likely to use analogies and less likely to use similes. It was also found that goal is the most important factor, with a significant relation to all other variables, and that embodiment is often invoked in both students' and reviewers' metaphors. We conclude that design education should take full advantage of students' natural ability to benefit from similarity relationships.Article Citation - WoS: 15Citation - Scopus: 19Associations Between Thermal and Physiological Responses of Human Body During Exercise(MDPI, 2017) Başaran, Tahsin; Zora, Süleyman; Balcı, Görkem Aybars; Çolakoğlu, MuzafferIn this study, thermal behaviours of the athletes were investigated with respect to thermal comfort and exercise intensity. The relationship between an index for analysing thermal comfort (Predicted Mean Vote: PMV) and Rating of Perceived Exertion (RPE) which shows exercise intensity and exhaustion level was evaluated. Eleven moderately trained male athletes (V) over dotO(2max) 54 +/- 9.9 mL.min(-1).kg(-1)) had volunteered for the study (age: 22.2 +/- 3.7 years; body mass: 73.8 +/- 6.9 kg; height: 181 +/- 6.3 cm; Body surface area (BSA): 1.93 +/- 0.1 m(2); body fat: 12.6% +/- 4.2%; (V) over dotO(2max): 54 +/- 9.9 mL.min(-1).kg(-1)). Experiments were carried out by using a cycle ergometer in an air-conditioned test chamber which provided fresh air and had the ability to control the temperature and relative humidity. The study cohort was divided into two groups according to maximal oxygen consumption levels of the participants. Statistical analyses were conducted with the whole study cohort as well as the two separated groups. There was a moderate correlation between PMV and RPE for whole cohort (r: -0.51). When the whole cohort divided as low and high aerobic power groups, an average correlation coefficient at high oxygen consumption cohort decreased to r: -0.21, while the average correlation coefficient at low oxygen consumption cohort increased to r: -0.77. In conclusion, PMV and RPE have a high correlation in less trained participants, but not in the more trained ones. The case may bring to mind that thermal distribution may be better in high aerobic power group in spite of high RPE and thus the relation between PMV and RPE is affected by exercise performance status.Article The Sustainability of an Urban Ritual in the Collective Memory: Bergama Kermesi(MDPI Multidisciplinary Digital Publishing Institute, 2019) İnceköse, ÜlküBergama Festival, locally known as Bergama Kermesi, is an annual festival which dates back to 22 May 1937 in the city. It came into existence as a result of Ataturk's intention to introduce this, an extraordinary town with its historical and cultural properties, and promote it internationally. The Festival is an important element in the collective memory of the city. Initially, it was a civic event, a device in the formation process of the Turkish Republic. However, now, it is a civil event for national and international representatives, and a festival that allows locals and guests from different social, economic, and cultural backgrounds to mix freely and equally for a certain period. In the course of the Festival, the public buildings and the open spaces of the town become places of activity and entertainment. Parks, stadiums, the town square, and streets function as spaces for a variety of activities. Looking back at its 81-year history, one can notice some important changes in the Festival's cultural and social practices, from an earlier state-dominated character into the current more publicly oriented one. This article studies the change of Bergama Festival as an invented tradition' into an element of the collective memory in town from the perspective of different public affairs that it introduces. In this regard, the article will also show how an urban ritual can maintain its sustainability by keeping itself fresh in the social life.Article Citation - Scopus: 3Climate Based Daylight Simulations With Evaldrc - Analysis of Daylight Redirecting Components(TU Delft Open, 2017) Bauer, Carsten; Kazanasmaz, Zehra Tuğçe; Wittkopf, StephenThe new calculation tool EvalDRC enhances current strategies for the simulation of Daylight Redirecting Components (DRCs). It is built upon RADIANCE as a core simulation engine and uses the daylight coefficient method, climate based sky models for annual simulations, and daylight metrics for data reduction. Contribution Photon Mapping is introduced as a new method for physically correct DRC simulation. Further new features are: separate True Sun Coefficients for a less approximated, more accurate treatment of the sun contribution and monthly breakdowns of the Spatial Daylight Autonomy, and Annual Sunlight Exposure metrics for more detailed information about DRC performance over the course of the year. To show the versatility of the tool, two application studies were carried out in which either measured Bidirectional Scattering Distribution Functions (BSDF) or detailed geometry models were used for the DRC simulation. © This work is licensed under a Creative Commons Attribution-NonCommercial 4.0 International License.

With the involvement of local authorities, civil initiatives and neighborhood organizations, it is possible to observe a similar attention in the formation of urban spaces in Turkey. Driven from this approach, this study examines the bottom-up transformation of a cultural space existing since 1960s in Izmir, Guzelyali. To reveal the process of how civic empowerment operated, we simulate a remembering process and curate the process in order to make things visible. The process examines an urban installation to reveal narratives behind collective action through reading collective memory. The scope is to re-read the past in the present in order to generate new processes of civic engagement, and thus actions, in urban spaces. © 2017 Urban Creativity.Article Citation - Scopus: 9Behind the 3d Scene: a Gis Approach for Managing the Chronological Information of Historic Buildings(MDPI, 2018) Saygı, Gamze; Agugiaro, Giorgio; Hamamcıoğlu Turan, MineHistoric buildings are representations of cultural systems throughout time. Thus, it is important to shed light on any given historic building’s chronological information by means of restitution, that is, the descriptions of different (re)compositions of a building for different historical states. However, the representation of information beyond the geometric, spatial, and physical characteristics of a historic building carries a crucial importance in the holistic understanding of historical changes. This requirement consists of representation, archival, assessment, and management aspects. Nevertheless, covering all these aspects is still quite challenging. Thus, three-dimensional (3D) visualization in digital platforms is considered, which indeed seems to be the most desirable way today. This article proposes a methodology through adopting an approach based on the Geographical Information System (GIS) and further develops a digital “container” as a 3D digital model for the archiving of a building’s chronological information. This does not only cover the geometric and spatial aspects, but also the historical resources and their reliability. The paper concludes that the developed prototype may lessen the future investigation effort of heritage specialists by making the chronological information of a historical building more integrated and coherent, through increased readability, accessibility, and visibility. This, in turn, supports the planning of restoration projects, as well as provides a static and comprehensive archive. © 2018 by the authors.

Repeated-measures design was adopted to identify the impact of variations in daylight levels that were manipulated through the shading system configurations (shading-on; shading-off). A total of 30 subjects performed visual and cognitive demanding tests. Performance measures were supported by subjective data and eye-related measures during the experimental analysis. Results revealed that the use of a shading system had positive impact on sustained attention. Concerning ocular measures, percentage of eye closure values showed opposite tendencies among vigilance and sustained attention demanding tests. Eye aspect ratio-max and blink duration were significantly correlated with reported glare sensation. In all tests, eye aspect ratio-max was found significantly higher in lower illuminances. Search velocity was significantly correlated with ocular variables in higher illuminances whereas sustained attention showed an opposite trend. This, initially, explains that even slight differences in daylight illuminance might have distinctive effects on the relationship between different groups of assessment variables while measuring cognitive load. Secondly, it proves the significance of carrying out sensitive experiments in terms of both light levels and test characteristics.Conference Object Visual Planning and Urbanism in the Mid-Twentieth Century: Conference at Newcastle Upon Tyne, Uk, 11-13 September 2007(International Seminar on Urban Form, 2008) Erten, ErdemPlanning attitudes with a particular focus on visual and three-dimensional planning have been insufficiently studied in histories of modernism. This conference, sponsored by the UK Arts and Humanities Research Council, focused on ‘a strand of more practical urbanism, modernist in flavour but historically informed [which sought] to recover positive conceptions of the city and town after the perceived deprivations of the nineteenth century’. Dealing with a timespan similar to that of narratives of modernist planning which targeted a radical reformation of the city – from the CIAM doctrine codified by the Athens Charter to the de-urbanist proposals of Frank Lloyd Wright’s Broadacre City – most of the attitudes discussed in the conference papers remained critical of such radical restructuring.
