A myth? Sustainable tourism as a tool for rescuing traditional spaces: a case study from Turkey, Ankara Z. Ozcan, N. Ayalp & G. Guner Aktas TOBB University of Economics and Technology, Turkey Abstract The concept of social sustainability should be considered and investigated in developing the conditions of traditional urban spaces. Sustainable tourism can be a basic tool for the physical conservation of architectural heritage. The traditional spaces regain considerable visual and economical value with tourism investments but the social reactions are to the contrary. In the content of the study, two different characteristically spaces were selected in the city of Ankara. The selected urban core was composed of 19th century Ottoman dwellings called \“Hamamonu” which have not been considered for a long time. The local municipality developed a project to rehabilitate a part of this area with the help of tourism and left the other part untouched \“Hamamarkasi”. Social, physical and spatial aspects will be questioned and the opinions of respondents will be output about the rehabilitation project. Keywords: sustainable tourism, traditional space, hamamönü, hamamarkası. 1 Introduction The oldest urban core of a settlement covers special spaces that help to differentiate it from the others with its original spatial character. In developing countries like Turkey, they are \“lost” urban spaces turned to squatter zones, composed of \“unpopular” traditional dwellings. Deterioration of the physical space is also the indicator of social change. The new housing zones lead to a social migration from the traditional urban core, leaving the place to lower income groups unaware of their possession responsibilities, resulting in the further collapse of the architectural indoor and outdoor spaces. In several cases, it is observed that not only the physical spaces but also the user profile changes Sustainable Tourism V 297

Assessing the Reliability of Turkish Building Energy Performance Tool (bep-Tr2) by Case Tests
(EDP Sciences, 2019) Harputlugil, G.U.; Zeki Yilmazoglu, M.; Unlu, G.
This paper aims to draw a general picture of the simplified software for calculation building energy performance based on Turkish Regulations called BEP-tr.v2, which was released at the end of 2017. Even the tool has a simplified calculation methodology, the discussion in this paper is going to be focused on assessing the accuracy of the tool by test cases. The assessing procedure for the tool has two steps. In the first step, box type cases are analyzed, and the results are compared with the results of a detailed energy simulation tool (BES) to perceive the percentage of deviations. In the second step, a current building is selected to use as a test case. The model results are compared with the real consumptions of the building to see the convergence rate of the tool (Bep-TR2). The results showed that the net energy calculation procedure of the methodology needs to be improved. © The Authors, published by EDP Sciences.

Assessment of Daylighting in a Historical Educational Building: Ankara University Faculty of Science Analytical Chemistry Laboratory
(Znack Publishing House, 2023) Avci, Ayse Nihan
The conditions of Ottoman architecture persisted during the republican period at the turn of the 20th century. Later, radical changes in the structure of the state affected the field of architecture, and changes in the world were reflected in our country. The structures that are the subject of architectural debates are typically early republican period buildings, which were built between 1920s and 1950s. On the other hand, in past buildings, the interior de-sign criteria that are important for the user in interior design have been the subject of interest in various disciplines. Lighting - daylighting and electric lighting - in different interiors is one of the design criteria that has intrigued many researchers. Laboratories, classrooms, studios, circulation areas, administrative spaces, offices, conference rooms, and wet spaces are all common features of educational buildings. Each of these spaces has unique lighting requirements. The aim of this study is to assess the daylighting performance in the interior and encourage similar studies in historical educational buildings rather than the architectural design of these buildings. Daylighting performance was assessed in the analytical chemistry laboratory at the Ankara University Faculty of Science, block A, which was built during the Second National Architectural Movement and bears the traces of Sedad Hakki El-dem, Emin Onat, and Paul Bonatz. A morning interval (10:00-11:00) where the courses are considered the most productive was chosen for the evaluation. The results were compared and interpreted with the values specified in the standards; the measurement is limited to the day and time interval.

Effects of Occupant Behavior on the Energy Performance of Dwellings: a Sensitivity Analysis
(Locke Science Publ Co inc, 2016) Harputlugil, Gülsu; Harputlugil, Gulsu Ulukavak; Bedir, Merve; Mimarlık
This paper focuses on the influence of occupant behavior on the energy performance of dwellings in the Dutch context. The aim of this study was to identify, how the energy performance of a dwelling is sensitive to the behavior of its occupants. To this end, the study's methodology adopted the Monte Carlo method of analysis, one of the most commonly used means of analyzing the approximate distribution of possible results on the basis of probabilistic inputs. Data related to occupant behavior were generated from a survey of 313 households in The Netherlands. The Dutch reference row house was used to test the behavioral patterns, and the test results were determined through simulation-based modeling. The key input parameters were presence, heating control patterns (thermostat and radiators), and ventilation control patterns (windows, grilles, and mechanical ventilation), while minimum indoor resultant temperature and heating energy demand served as the key output parameters. The results showed that both heating energy demand and minimum indoor resultant temperature were most sensitive to the thermostat setting and most robust in relation to the radiator setting.
Impact of Complexity on Perceived Affective Quality and Perceived Restorativeness in Indoor Soundscapes
(European Acoustics Association, EAA, 2023) Acun, V.; Aksel, Elif; Aksel, E.; İç Mimarlık
Eventfulness and pleasantness are two prominent components of soundscape perception, and their interplay creates attributes that are used to measure the perceived affective quality of soundscapes. Even though restorativeness is not among the principal components of soundscape perception, it is involved with soundscapes' perceived affective quality attributes. While the contribution of these attributes is well established, there is still a lack of understanding regarding how soundscape complexity impacts perceived restorativeness and perceived affective quality. There are tools, such as the Acoustic Complexity Index, to measure the complexity of natural soundscapes but soundscapes of the built environment lack such an index. This study aims (1) to understand the relationship between complexity, perceived affective quality and perceived restorativeness and (2) to explore and compare the effectiveness of different means of measuring acoustical complexity. With this regard, we conducted an online questionnaire survey which consisted of twenty soundscape recordings. We asked the participants to evaluate the perceived affective quality and perceived restorativeness of each recording. We then calculated the acoustic complexity indices, Acoustic complexity, Acoustic Diversity, Acoustic Evenness, and Normalized Differences Soundscape Index. Finally, we conducted a series of statistical analyses to explore the relationships between each variable. © 2023 Acun et al.

Investigating Syrian Refugees' Choice of Location in Urban Areas as a Subjective Process: a Cross-Case Comparison in the Neighbourhoods of Onder (Ankara) and Yunusemre (Izmir)
(intellect Ltd, 2021) Kahraman, Zerrin Ezgi; Gungordu, Feriha Nazda
In migration literature, the growing interest in the localized and subjective forms of refugee emplacement in urban areas following the influx of Syrian refugees has brought along new debates on how to approach the location choices (LC) of refugees. Accordingly, in this study, we investigated the different dimensions of Syrian refugees' location choices at the urban/neighbourhood level. Specifically, we aimed to understand the dynamics behind the growing tendency among Syrian refugees in Turkey to settle in neighbourhoods that are close to inner-city industrial sites by conducting two case studies in the Onder neighbourhood of Ankara and the Yunusemre neighbourhood of Izmir in a comparative manner. From the twenty-three interviews conducted with Syrians, we uncovered the themes of LC and categorized them in accordance with the dimensions of LC addressed in the literature. We identified three main dimensions that affected Syrians' location choices at the neighbourhood level as: economic (the availability of job opportunities, public and commercial services, the affordability of accommodation), socio-cultural (the existence of co-ethnics, kinship/ethnic relations) and socio-spatial (proximity to the city centre, transportation, public and commercial services, workplaces). Here, we acknowledged the intertwined relation between these dimensions and refugee subjectivity in LC.
An Investigation of Sound Sources in Smart Houses for Improved Machine-To Communication
(European Acoustics Association, EAA, 2023) Kitapcı, Kıvanç; Alkan, A.; Yorukoglu, P.N.D.; Kitapci, K.; İç Mimarlık
This study aims to investigate the ever-evolving indoor soundscapes of smart houses by classification of the sounds emitted from smart devices. Nowadays, communication is no longer limited to person-to-person. Smart devices frequently communicate with users by verbal or tonal notifications. Therefore, acoustic characteristics of smart houses, especially reverberation time and background noise levels, have increased importance in achieving improved and lossless signal transfer and speech intelligibility. It is hypothesized that most houses are unsuitable for effective tonal and verbal communication with smart devices regarding acoustical conditions. Within the scope of the study, the devices found in the smart technology market were investigated. The sounds emitted from the identified devices were then classified according to their communicative nature (verbal/tonal), designability, customizability, and cause (i.e., intentional or consequential). The acoustic requirements for effective communication with the individual smart devices were analyzed in addition to the resulting holistic indoor soundscape of the smart houses The results of the study will help architects, interior architects, and other environmental designers to improve the quality of communication while guiding future research to understand indoor soundscapes of smart houses. © 2023 First author et al.

Leed Certified Mixed-Use Residential Buildings in Istanbul: a Study on Category-Based Performances
(Istanbul Teknik Universitesi, Faculty of Architecture, 2021) Süzer, O.
The building industry has a significant negative effect on climate change and increases other environmental problems at the global scale. LEED, which is one of the most globally used environmental assessment tool, provides the certification of projects according to the evaluation criteria of green buildings under certain categories. On the other hand, an emerging form of architecture, the mixed-use residential high-rise building (MRB), appears in larger numbers especially in the metropolitans of developing countries, such as Istanbul. This building typology displays a positive approach in the context of sustainability. Since they are high-budget projects addressing to high-income groups, it is inherently expected that they have a green approach as a social responsibility. The objective of this study is to analyze LEED certified MRBs in Istanbul by focusing on their prioritization of evaluation categories. LEED’s database revealed a total of twenty-one certified projects under the New Constructions (v.3) scheme. Based on the gained points by these projects, mean rank values of the evaluation categories were calculated, which indicated the priorities given by this sample group. Furthermore, the conducted Kruskal-Wallis test showed there was highly significant difference among the rankings of the categories for these projects. Based on these rank order tests, obtained category priority order of MRBs was compared to the one implied by LEED’s assigned category weights. It was found that Energy and Atmosphere category gained much lower attention than required. Taking the results of the study into account, certain conclusions were drawn for this building type in Istanbul. © 2021, Istanbul Teknik Universitesi, Faculty of Architecture. All rights reserved.
A Literature Survey on Integration of Wind Energy and Formal Structure of Buildings at Urban Scale
(Springer international Publishing Ag, 2018) Paltun, Serpil; Gultekin, Arzuhan Burcu; Celebi, Gulser
Providing the needed and indispensable steady, quality and safe energy is one of the most important issues today. Wind energy is one of the most important renewable energy source. Wind energy has found uses much more in water pumping and obtaining electricity in rural areas until last years. Today, wind energy has taken its place in the energy sector as an alternative source of energy production. High-density building arrays within a city, the combination of indoor and outdoor spaces with different purposes effect wind flow and acceptable wind comfort. In urban areas, wind energy and wind comfort are important requirements. Not only in new urbanisation areas but also for existing urban areas and city centers acceptable wind comfort plays an important role among and around buildings. When viewed from this angle, the aim of this study is enlightening the building aerodynamics, wind effect and wind energy in urban environment, and also giving information about how to analyze the wind comfort and design criteria in dense urban areas.
Re-Thinking of Energy Consumption Classification by the Patterns of Occupant Behaviour in Dwellings: a Conceptual Framework
(Free University of Bozen Bolzano, 2015) Harputlugil, G.U.; Harputlugil, Timuçin; Harputlugil, T.; Harputlugil, Gülsu; Mimarlık
The aim of this paper is to present the conceptual framework of a TUBİTAK funded project titled "Developing a New Methodology to Improve Housing Quality in Turkey Based on Effects of Occupant Behavior on Energy and Comfort of the Dwellings". Although the objective of the project is the development of new methodologies and tools to be used for the definition of effects of behavior profiles of housing occupants on the energy consumption and usage of this knowledge for building new houses and renovation of existing buildings, here the first step of research has been executed. By defining sensitivity of occupant behavior on energy consumption, it is planned to classify different models of occupant behavior. With data provided, the aim is to develop an "occupant behavior labeling" which rates occupants instead of buildings. To provide the mentioned data, sensitivity analysis of existing occupant behavior will be analysed based on the Monte Carlo Methodology. This methodology is one of the most used methodologies to analyse accurate distribution of possible outputs relied on inputs based on probability. Inputs for this research are (1) number of occupants for each space (for weekdays and weekend) (2) behaviour for ventilation (Window open/closed and mechanical ventilation on/off) (3) control of heating systems (radiator on/off and/or thermostat degree). These data will be provided with survey and data logging of chosen a house occupant group. As a consequence of the research, the aim is not only to rate the behavior of housing occupants but also determine occupancy groups/labels. With this approach, based on occupant's behavior labeling, the aim is to realize fast and affective applications for renovation of existing buildings. Moreover, by evaluation/assessment of houses which will be designed in the future based on determined occupant profiles allow to produce high performance dwellings. © 2015 by Bozen-Bolzano University Press Free University of Bozen-Bolzano All rights reserved.
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.

A Review Based on Oled Lighting Conditions and Human Circadian System
(Gruppo del Colore ? Associazione Italiana Colore, 2023) Akbay, S.; Avci, A.N.
Light is a form of energy that affects the human sleep cycle, working hours, alertness, productivity, and well-being. As one of the essential environmental factors, lighting requires extensive research to understand the human-environment interaction. Earlier studies reveal that various artificial lighting technologies are utilized to investigate the human circadian system; experiments employing solid-state lighting (SSL) sources are still being conducted to determine how the human circadian system is affected. Due to the advantages of OLED (organic light-emitting diode) lighting, there is a need to enhance this form of artificial lighting in an indoor environment. This paper focuses on a literature review on artificial lighting sources, particularly OLED lighting, used from the past to the present. This article also discusses how OLED lighting can influence the human circadian system in terms of different characteristics of lighting in an indoor environment. © 2023, Gruppo del Colore?

(Fac Teacher Education, 2014) Kahraman, Zerrin Ezgi; Kahraman, Z. Ezgi; Sakarya, Arif Orçun; Sakarya, A. Orcun; Şehir ve Bölge Planlama; İşletme
Bologna Process studies in Cankaya University's Interior Architecture Department (INAR), Turkey have been initiated in 2008. The goal of this study is to explore students' perceptions about the new programme outcomes framed with the Turkish Higher Education Qualifications Framework and to provide a set of guidelines for the Bologna Process to be implemented. A questionnaire including semi-structured questions is conducted in the data collection process. Content analysis method is used in order to examine students' perceptual outcomes. The findings of the study display that students' perceptions underline the importance of the acquisition of knowledge, skills and competences in social, economic and managerial dimensions of the professional life. Results also reveal the need of students for the acquisition and use of communicative, collaborative and interdisciplinary aspects of the profession and their expectations on both theoretical and practical contents of INAR courses. Furthermore, this study which mainly followed a student-cantered approach concluded that it is also possible to generalize new programme outcomes through the active participation of students.
Virtual Interior Environment: Influence of Colour on the Sense of Immersion
(Gruppo del Colore ? Associazione Italiana Colore, 2023) Gökmenoğlu, F.; Akbay, S.
This article investigates the effects of colour on the sense of immersion in virtual interior environments. The perceptual significance of colour in interior design necessitates a critical evaluation of the three dimensions of colour-hue, saturation, and lightness (HSL)-in the context of their application in virtual environments (VEs). The study aims to investigate how the sense of immersion in virtual interior environments varies depending on hue, saturation, and lightness and to examine the extent to which colour dimensions influence the sense of immersion in VEs. In this study, the HSL colour space was employed to create varying degrees of colours, and an online survey was conducted to understand the individuals’ sense of immersion in different virtual interior settings. The findings suggest that reducing the degree of lightness of colours in a virtual interior environment enhances the sense of immersion. In addition, the study reveals that whether a virtual interior environment highlights natural or artificial lighting, augmenting the degree of lightness of colours intensifies the sense of immersion in the perceived environment. © 2023, Gruppo del Colore?
