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.

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.

Analyzing Natural Lighting Conditions From the Perspective of Biophilic Design in Indoor Office Environments
(Institute of Physics, 2022) Avci, A.N.; Karaman, G.D.
The term "biophilic design"is recognized by some designers who coined a word for designing instinctively using fresh understandings, reasons, and views, which helps reconnect us with the natural world in the indoor environment. Within the various patterns that connect humans with nature, natural lighting provides an orientation to the day and night according to the sun's location and cycles, which is essential for human health and wellness. The supply and quality of natural lighting, including its influence on mood, have been extensively investigated and written about for many years in various locations and the overlapping science and design disciplines. This paper analyzes the biophilic design approach to mood for the natural lighting conditions that change according to the position of the office environments in winter. The selected two indoor office environments were located in the Faculty of Architecture at Çankaya University on Main Campus, on the second floor of the building. Office-1 overlooked the design studio, preventing it from taking natural lighting directly, and Office-2 directly penetrated the natural lighting. Natural lighting-based photos were taken from the selected offices during three periods of the day. The photos and a survey were directed at the two groups: Group 1 consisted of the students who took the Natural and Artificial Lighting Course, and Group 2 students who did not take this course. The experimental instruments analyzed their moods to evaluate natural lighting conditions. © Published under licence by IOP Publishing Ltd.

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.

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.

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.

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.

A Comparative Research on Space of Women in Prayer Place Interiors of Celestial Religions: Cases From Istanbul
(Gazi Univ, 2020) Disli, Gulsen; Ozcan, Zuhal
Cross-cultural comparison has been used in architecture mostly to discuss the components of culture, knowledge, and value systems, yet to date there is not a specific comparative study on gendered architecture in prayer places of celestial religions, namely Judaism, Christianity, and Islam. Hence, this study aims to reveal how attendance of women in prayer places with different national, historic, religious, and cultural characteristics shaped architectural space organization and to assess potential similarities and differences of women's section in prayer spaces of celestial religions by examining literature survey, archival and historic research, including field observations. In addition to general observations in building scale, some exemplary historic synagogues, churches, and mosques in Istanbul still in use have been chosen as case studies, and their plan typologies, as well as types and locations of women's galleries/sections have been discussed. Cross-cultural comparison parameters were; development of women's section in prayer places as a structured architectural space and basic architectural terminologies used to define women's section. The major conclusion of the study is that originally women had right to worship in prayer spaces without any physical separation in all three religions, yet in time the place of women had a more defined/divided/structured character especially in Islam and Judaism. The study also indicates that while at present day, gendered architecture is still the predominant approach in Islam and in Orthodox Judaism; mix congregation in a single-unsegregated space for both sexes is more common in contemporary society of Christianity.

A Comparative Review of Environmental Concern Prioritization: Leed Vs Other Major Certification Systems
(Academic Press Ltd- Elsevier Science Ltd, 2015) Suzer, Ozge
The matter of environmental concern prioritization integrated into globally used green building rating systems is a fundamental issue since it determines how the performance of a structure or development is reflected. Certain nationally-developed certification systems are used globally without being subjected to adjustments with respect to local geographical, cultural, economic and social parameters. This may lead to a situation where the results of an evaluation may not reflect the reality of the region and/or the site of construction. The main objective of this paper is to examine and underline the problems regarding the issue of weighting environmental concerns in the Leadership in Energy and Environmental Design (LEED) certification system, which is a US-originated but globally used assessment tool. The methodology of this study consists of; (i) an analysis of the approach of LEED in the New Construction and Major Renovations scheme in version 3 (LEED NC, v.3) and the Building Design and Construction scheme in version 4 (LEED BD + C, v.4), (ii) case studies in which regional priority credits (RPCs) set by LEED for four countries (Canada, Turkey, China and Egypt) are criticized with respect to countries' own local conditions, and, (iii) an analysis of the approaches of major environmental assessment tools, namely; BREEAM, SBTool, CASBEE and Green Star, in comparison to the approach in LEED, regarding the main issue of this paper. This work shows that, even in its latest version (v.4) LEED still displays some inadequacies and inconsistencies from the aspect of environmental concern prioritization and has not yet managed to incorporate a system which is more sensitive to this issue. This paper further outlines the differences and similarities between the approaches of the aforementioned major environmental assessment tools with respect to the issue of concern and the factors that should be integrated into future versions of LEED.
