Aciksaray "open Palace": a Byzantine Rock-Cut Settlement in Cappadocia
(Walter de Gruyter Gmbh, 2014) Ozturk, Fatma Gul
Courtyard complexes formed entirely out of the volcanic rock mass in Cappadocia, in Central Anatolia, differ from the other rock-cut structures in the region, in both scale and elaboration of design. There are more than forty such complexes in Cappadocia, either gathered in one location or isolated. Located on the Nevsehir-Gulsehir road, Aciksaray contains nine such complexes in close proximity, many of which feature monumental facades as well as reception areas and utilitarian spaces such as large stables around a courtyard. This paper, in the light of survey results, presents site analysis and architectural readings that lead the discussion of the nature and stages of occupation at Aciksaray. By doing this, the paper aims to bring new insights to the discussion on courtyard complexes, adding details and nuance to our understanding of the Aciksaray settlement, while noting similarities with other settlements in the region. Underlining the secular and elite character of the Aciksaray settlement, this study contributes in particular to enlarging the picture of medieval life in Cappadocia, and in general to the studies of Byzantine domestic architecture, for which architectural evidence is still scarce.

The Acoustic Characterization of Worship Ambiance and Speech Intelligibility in Wooden Hypostyle Structures: The Case of the Aslanhane Mosque
(Springer Singapore Pte Ltd, 2021) Kitapci, Kivanc; Celik Basok, Gulsah
The challenge in the acoustics design of the traditional mosque is twofold. First, the interior atmosphere of the space should create a sacred feeling on the users' holistic and phenomenological spatial perception, which is generally recognized as a direct effect of increased reverberation time (T30) and low clarity (C80). Second, speech should be adequately intelligible, which requires a low T30 and high speech clarity, contradicting the initial concern of the sacred atmosphere. We hypothesize that in Islamic architecture, wooden hypostyle mosques may comply better with the reverberation time requirements of speech intelligibility, while maintaining the sacred feeling, due to their comparatively absorptive surface finishing materials and structural elements. The Aslanhane Mosque is a unique sacred structure within its era of construction, well-known with its wooden columns and ceiling. It is an important case for room acoustics analysis of such holy spaces. This study aimed to analyze the room acoustic measurement results of the Aslanhane Mosque, evaluating the intelligibility of speech and interpreting the sacred feeling created by reverberance, envelopment, and spaciousness, which are all crucial in such holy structures. It is revealed that although the Aslanhane Mosque's subjective rating for speech intelligibility is "good," the overall low volume of the mosque and the lack of surface reflections decrease the sacred sensation. Additionally, the intelligibility of speech is vulnerable to obstacles within the line of sight, such as load-bearing columns. Lastly, it was observed that the increase in T30 at low frequencies improved the sacred sensation, envelopment, and spaciousness, without any profound negative impact on the intelligibility of speech.

Addressing Earthquake Risk and Climate Crisis Together in Spatial Planning
(Kare Publ, 2021) Orhan, Ezgi; Peker, Ender
Cities' vulnerability to natural and man-made threats are ever increasing. Cities are under the threat of both natural disasters such as earthquakes, avalanches and landslides; and climate-driven challenges such as excessive precipitation, heatwaves and droughts. This calls for a need of handling natural and human systems together for the future of cities. However, climate and earthquake action plans which naturally present a direct link to spatial planning, are often produced separately in the Turkish planning practice. This study advocates that strategies for combating earthquake and climatic challenges should be harmonized together within the spatial planning system, and respectively, aims at presenting a holistic planning approach. For this purpose, the study first examines the ways in which disaster and climate issues are addressed in the current laws and national action plans. Then, in line with the 'Regulation on the Preparation of Spatial Plans', it examines the spatial planning scales with an aim of determining the potential areas in which disaster and climate issues could be planned together. Taking this as a point of departure, the paper presents a set of planning strategies responding to earthquake risk and climate crisis at regional, city, neighbourhood and building scales. It discusses synergies and conflicts among these strategies at different scales. This study targets to develop a holistic perspective for earthquake and climate change induced disasters, for the decision-makers and practitioners operating in spatial planning processes.

An Integrated Framework on Soundscape Perception and Spatial Experience by Adapting Post-Occupancy Evaluation Methodology
(Sage Publications Inc, 2018) Aburawis, Ayad A. Mohamed; Yorukoglu, Papatya Nur Dokmeci
The effecting factors of soundscape perception and space experience have a very close relationship. This study aims to synthesize the diversity of soundscape classifications and schemes and unify such factorial variations in order to develop an integrated framework for soundscape perception and spatial experience within a systematic review of recent progress and by adapting post-occupancy evaluation methodology. First, factors under soundscape perception and space experience are reviewed in detail and merged to form conceptual classification models. Six soundscape perception factors are formed as (1) sonic, (2) spatial, (3) temporal, (4) psychological, (5) behavioural and (6) personal. Similarly, five space experience factors are formed as (1) user, (2) usage, (3) architectural design, (4) social context and (5) physical environment. All related items in the literature are presented and the sub-items under each factor are exemplified. Second, factors under the merged conceptual models are integrated by considering occupants' experience of space regarding their variance in perception of soundscapes through acoustical post-occupancy evaluation. An adapted study design is proposed under indicative, investigative and diagnostic stages of the post-occupancy evaluation by presenting the methods, data types and factorial correlations for each stage.

Analysing Sound Environment and Architectural Characteristics of Libraries Through Indoor Soundscape Framework
(Polska Akad Nauk, Polish Acad Sciences, inst Fundamental Tech Res Pas, 2016) Yorukoglu, Papatya Nur Dokmeci; Kang, Jian
This study presents the indoor soundscape framework in detail by describing the variables and factors that form an indoor soundscape study. The main objective is to introduce a new indoor soundscaping framework and systematically explain the variables that contribute to the overall evaluation of an indoor soundscape. Hence, the dependencies of physical and psychoacoustical factors of the sound environment and the spatial factors of the built entity are statistically tested. The new indoor soundscaping framework leads to an overarching evaluation perspective of enclosed sound environments, combining objective room acoustics research and noise control engineering with architectural analysis. Therefore, it is hypothesised that case spaces with certain plan organisations, volumetric relations, and spatial referencing lead to differentiated sound pressure level (SPL) and loudness (N) values. SPL and N parametric variances of the sound environments are discussed through the statistical findings with respect to the architectural characteristics of each library case space. The results show that the relation between crowd level variances and sound environment parametric values is statistically significant. It is also found that increasing the atrium height and atrium void volume, the atrium's presence as a common architectural element, and its interpenetrating reference and domain containment results in unwanted variances and acoustic formations, leading to high SPL and N values.

Analytic Hierarchy Process (Ahp) as an Assessment Approach for Architectural Design: Case Study of Architectural Design Studio
(Konya Technical Univ, Fac Architecture & design, 2018) Harputlugil, Timucin
Architectural design is complex and can be defined as an effective decision-making activity based on problem solving. This complexity is not based on content and volume of problems, but also heterogeneity and uncertainty of information provided for assessment, subjective approaches, and a large number of the criterion for assessment. The aim of this research paper is to contribute to the researches for assessment of architectural design by providing a novel approach based on Analytic Hierarchy Process (AHP) - a Multi Criteria Decision Making (MCDM) method. The approach supports an effective comparative analysis among the alternative projects based on determined criterion. The methodology is implemented with a case study in one of the design studios of Department of Architecture of Cankaya University on final design projects of a group of students with observation, research and assessment. The data used in the assessment is collected through interviews and surveys which is analysed by the help of a software. Based on the outcomes of the AHP-based approach, it has been seen that this approach can provide numerical results that are comparable, measurable, gradable, consistent and can be reported separately for each assessor. However, it has also been found that the AHP-based method is suitable for evaluating only a limited number of projects. With the research, and by setting thresholds levels for evaluation, it has become clear that successful and unsuccessful projects can be separated for achievement and competence. Consequently, it has been observed that the approach has considerable potentials to be further developed to evaluate architectural projects comparatively, especially for architectural students' projects, and other architectural projects such as architectural design competitions.

Analyzing the Compliance and Correlation of Leed and Breeam by Conducting a Criteria-Based Comparative Analysis and Evaluating Dual-Certified Projects
(Pergamon-elsevier Science Ltd, 2019) Suzer, Ozge
Certified green buildings are known to demonstrate high environmental performance; however, it is still not clear where they stand among each other, unless certified by the same body. This study aims to examine the compliance and correlation between the most prominent green building rating systems, LEED and BREEAM. It also estimates how a project would be graded by one system if already certified by the other. Regarding the methodology of the study, the intents of evaluation criteria in the latest versions for new constructions of LEED and BREEAM are analyzed. Commonly addressed and different concerns are determined, and the scales for assigning their award levels are compared. It is observed that they have a high level of compliance because 83% of the environmental concerns are commonly addressed issues. Moreover, it is derived that a dual-certified project aiming to achieve the same award level in both assessments has to display a better performance in BREEAM as it includes a higher number of concerns to be fulfilled. Based on the correlation analyses on twenty dual-certified buildings, the results from the scatter plot diagram, Pearson's Correlation Coefficient (r) and Paired Samples t-Test show that there is a large positive linear correlation and that LEED scores are significantly higher than BREEAM scores. Furthermore, the difference between the averages of LEED and BREEAM scores and the average difference between award levels indicate that if there would be a difference in ratings of dual-certified projects, it would be in favor of LEED by one award level.

Architect - Structural Engineer Collaboration in Sustainable Structural System Design
(Gazi Univ, 2011) Ozmen, Cengiz; Özmen, Cengiz; Unay, Ali Ihsan; Mimarlık
This paper explores ways of collaboration between architects and structural engineers in the design of sustainable structural systems. Areas of collaboration are explored in terms of seismic design of new structures and rehabilitation of existing structures. Multidisciplinary design teams and an integrated design approach are critical to the process of sustainable building construction. The required group-work skills should be acquired by architects and engineers during their professional education. As a result, this paper also investigates ways in which the structural design education of architects and structural engineers can be redesigned to make their future professional collaboration more harmonious.
Architectural Design - Structural System Conformity Problems Encountered in the Design and Application Processes of Stick Aluminium Curtain Wall Systems in Turkey
(Gazi Univ, Fac Engineering Architecture, 2022) Ozmen, Cengiz; Saban, Muge
Stick aluminium curtain wall (SACW) systems are common curtain wall systems in Turkey. These sytems offer many advantages including architectural variation, modular design, ease of production and assembly. Beside their architectural properties SACW systems create significant load effects on structural systems. These load effects include lateral loads such as seismic and wind loads as well as static vertical loads. This load transfer is not one way. The vertical and lateral displacements of building structures also act on curtain walls. Healthy load transfer between the SACW and the building depends on architectural decisions during the design and construction process. Due to their wide use SACW systems are prone to architectural mistakes. These mistakes often represent themselves at latter stages of the construction and require solutions which will affect the architectural characteristics and structural behavior of buildings. This study focuses on SACW design and construction processes to find the effects of architectural decisions on curtain wall behavior. Case studies that include architectural design mistakes are selected to classify and study the reasons and the solutions of these mistakes. The importance of cooperation between all the stakeholders including the architects and engineers is emphasized for the prevention of these mistakes.

Architecture and Ceramics
(Elsevier Science Bv, 2015) Berker, Olgu Sumengen
Most of the different art disciplines, meet each other on some intersections during the creation process. The art comes into life from the needs of human beings. Therefore the formation of these intersections are not so surprising for the art era. The aim of this paper is to set forth the association of architecture and ceramic art and interaction between them especially by means of the abstraction of contemporary ceramic artworks. Notions like inner space and outer space are mostly considered basic concepts of ceramic art. This conceptual consideration gains an importance when these concepts are viewed from the architectural perspective. Because these notions are also basic notions of architecture. While architecture transforms these notions into forms, it also creates outer spaces for the ceramic artworks. In this paper some chosen examples of ceramics are referenced from the ancient times until 20th century (when ceramic was accepted as an art discipline to express the ancient association of these two art disciplines. Then the artworks of contemporary ceramic artists are featured in terms of conceptual basis, styles, production methods and processes, and the opportunities that comes from the nature of ceramic materials. Abstracting the expressions of the contemporary ceramic artists in the architectural manner, resulted as the displaying how do these two art disciplines come together on the concept of inner and outer space.

Artificial Intelligence Applications in Earthquake Resistant Architectural Design: Determination of Irregular Structural Systems With Deep Learning and Imageai Method
(Gazi Univ, Fac Engineering Architecture, 2020) Bingol, Kaan; Akan, Asli Er; Ormecioglu, Hilal Tugba; Er, Arzu
Although the architectural design process is carried out with the collaboration of experts who are experienced in many different areas from the main preferences to the detailing stage, the major decisions such as plan organization, mass design etc. are taken by the architect. Computer Aided Design (CAD) programs are generally effective after the major decisions of the design are taken. For this reason, it is common for the main decisions, taken during the design process, to be changed during the analysis of the structural system. In order to prevent this, in the early stages of architectural design, earthquake system awareness and structural system design should be included as an design input; as, the failure of the structural system which did not considered well in the architectural design phase leads to unexpected revisions in the implementation project phase and thus leads to serious losses in both time and cost. The aim of this study is to create an Irregularity Control Assistant (IC Assitant) that can provide architects general information about the appropriateness of structural system decisions to earthquake regulations in the early stages of design process by using the deep learning and image processing methods. In this way, correct decisions will be made in the early stages of the design and unexpected revisions that may occur during the implementation project phase will be prevented.
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.

Audio-Visual Interactions and the Influence of Colour on Noise Annoyance Evaluations
(Springer Singapore Pte Ltd, 2021) Kitapci, Kivanc; Akbay, Saadet
This study aims to examine the influence of colour exposure on noise annoyance. Previous studies in the literature have focused mostly on the effects of colour exposure on loudness judgements; however, due to the cognitive nature of multisensory perception, the influence of colour on noise annoyance also needs to be investigated. Our experiments were designed to administer non-information-carrying sound signals (i.e. white noise) and visual stimuli (i.e. abstract colour samples) and to limit visual and auditory contextual information. Participants were asked to evaluate noise annoyance on an 11-point International Commission on Biological Effects of Noise (ICBEN) scale. The experiments were conducted in the form of audio-visual tests. During these tests, random combinations of three white noise sound samples with sound pressure levels of 66 dB(A) (-4 dB[A] acoustic condition), 70 dB(A) (0 dB[A] acoustic condition) and 74 dB(A) (+4 dB[A] acoustic condition), and six visual stimuli, including the elementary colours of the Natural Colour System (NCS)-yellow (Y), red (R), blue (B), green (G), white (W) and black (S)-were presented to a total of 42 participants. The black colour sample was used to measure the audio-only control condition for the three white noise sound samples. The results of the study reveal that the effects of sound, the effects of colour and the interaction effects of colour and sound on perceived noise annoyance were statistically significant. The effects of colour on the loudness evaluations of the previous studies and the effects of colour on noise annoyance evaluations presented in this study show very similar and concordant results, indicating that the effects of colour on noise annoyance depend on the sound pressure level (SPL). The results indicate that the hue contrasts of red-green, red-blue and yellow-blue and the lightness contrast of yellow-blue influenced perceived noise annoyance when the SPL was low or high. Within the contrast pairs, red and yellow were perceived to be annoying, whereas blue and green were perceived to be non-annoying.

Building a Framework for Analysing the Quality of Life at Neighbourhood Level: an Empirical Case From Ankara
(Penerbit Univ Sains Malaysia, 2020) Kahraman, Z. Ezgi; Gungordu, Nazda; Orhan, Ezgi
This article aims to analyse the indicators of quality of life (QoL) in a regeneration area in line with the subjective evaluations of neighbourhood residents. To this end, a total of 359 respondents were selected by random sampling in the Akpinar neighbourhood, Ankara, Turkey which was inhabited by squatter settlements and subjected to urban regeneration resulting in a substantial change in its physical, social, spatial and demographic structure. The neighbourhood was challenged by a landslide after the urban regeneration which affected the satisfaction levels of residents and constituted a contradiction for regeneration efforts. It is hypothesised that the QoL of neighbourhood residents is affected by the factors of quality of the built environment, public spaces, social environment, natural environment, services and facilities and safety. The findings indicate that neighbourhood level QoL is positively associated with the width of streets, adequacy of parking lots, adequacy of cultural facilities, adequacy of sewage and drainage systems, discreetness of inhabitants and peace and calmness in the neighbourhood. The present research contributes to the development of a more comprehensive schema for regeneration practices by considering both objective and subjective indicators and by revealing the importance of the public space's influence on the QoL for urban residents.

Building Sector Emission Reduction Assessment From a Developing European Economy: a Bottom-Up Modelling Approach
(Elsevier Sci Ltd, 2023) Sarica, Kemal; Harputlugil, Gulsu U.; Inaner, Gulfem; Kollugil, Esin Tetik
In this study, as a developing European economy, the Turkish building sector is assessed for potential CO2 emission reduction with a bottom-up modelling framework with a time horizon starting from 2015 until 2050. Three emission mitigation policies are studied for their emission reduction potentials, namely, increasing the usage rate of energy-efficient appliances, improving the energy performance of the building envelope in existing buildings, and increasing the use of energy-efficient heating and cooling systems. Based on these potentials, three emission reduction scenarios for 5%, 10%, and 21% compared to reference cases are designed and implemented. It is shown that much higher energy savings levels, 6%, 12%, and 28%, are achieved. It has been found that the cost-effectiveness of emission reduction scenarios depends on the policy mix as well as the future emission intensity of the electrical energy consumed, which can reduce the cost of mitigation down to the range of 100-200 USD/tonne CO2.

Changes and Problems of Conservation in Ankara-Ulus Historical City Center: Koyunpazari Slope and Atpazari Square
(Konya Technical Univ, Fac Architecture & design, 2021) Karakus, Filiz; Urak, Z. Gediz
Purpose In this study, the settlement located in Koyunpazari Slope and Hisar (Atpazari) Square, which has an important position in the Atpazari-Koyunpazari-Samanpazari area, which is the oldest part of the Ankara-Ulus Historical City Center, was examined in a way to include Cengelhan and Cukurhan. With this study, it is aimed to determine the changes and conservation problems in the field and to give direction to the changes planned for the future in the area. Design/Methodology/Approach Analysis and evaluation studies conducted in 1998 have been repeated in the mentioned area. Research and surveys have been conducted on the number of buildings in the area, the number of floors, the physical conditions of the buildings, the number of sub-units, types of activities, ownership status, frequency of purchasing goods, types of transportation, spatial competence, infrastructure competencies and future expectations of the working population. Findings As a result of these studies, the changes and problems occurred in the period from 1998 to 2020 have been determined. It has been observed that there are serious changes in the area due to cultural tourism, as in all over the world and in our country. The infrastructural deficiencies are the main problems identified in the area. Furthermore, it has been observed that the traffic problem has not been solved completely and also some buildings need repair. Research Limitations/Implications The fact that the field of study could not be expanded due to the application of the survey questions in the field of study in 1998 constitutes the limitations of this study. Social/Practical Implications With this study, it is aimed to draw attention to the conservation of the historical environment in Koyunpazari Street and Atpazari Square, which is an important point of the Ulus Historical City Center, and to create a social awareness about the preservation of the area in question. Originality/Value This study is significant as it discusses the conservation problems in one of the oldest areas of Ankara and aims to give direction to future changes in the field by formulating proposals for the solution of these problems.

Cittaslow Movement From a Critical Point of View
(Kare Publ, 2018) Can, Mehmet Cengiz; Ozmen, Ayca
The Cittaslow Movement, shaped upon the idea of slowness, emerged as a reaction to the negative effects of globalization on small cities. It was founded in 1999 in Italy through initiatives implemented by the mayors of 4 small towns (Greve in Chianti, Orvieto, Positano, Bra) and the founder of Slow Food. This movement, which aims to increase the quality of life by preserving and sustaining the local values of settlements, was quickly embraced by more than 200 small cities and towns in 30 countries. However, Cittaslow is still relatively new and developing movement, and the long-term results are not yet fully known. Cittaslow provides practical guidelines for a more livable settlement, rather than relying on theoretical concerns. It emerged as a result of social reflection rather than scientific research. Therefore, concomitant problems may arise in the implementation process. Nevertheless, in the near future, the concept is expected to continue to grow socially and scientifically through the efforts of Cittaslow International to improve the movement and as a result of the increasing interest of researchers and local authorities. It is therefore important to understand and interpret the essence of the Cittaslow Movement properly at this time. The aim of this article was to provide a framework for the founding ideas and goals of the Cittaslow Movement and to describe its development and progress. The outcomes thus far were evaluated from a critical point of view in order to make new proposals. The goal of this research was to raise awareness of the Cittaslow Movement among all stakeholders, particularly local authorities and residents.
