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.

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.

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 Structural, Architectural and Cost-Based Analysis of Seismic Design Principles Applied in Reinforced Concrete Residential Buildings in Turkey
(Crc Press-taylor & Francis Group, 2010) Ozmen, C.; Özmen, Cengiz; Mimarlık
This study demonstrates that it is possible to design earthquake resistant reinforced concrete residential structures without significant compromises in the spatial quality and economic viability of the building. The study addresses architects, structural engineers and private entrepreneurs who are the important players in the Turkish construction industry. In structural analyses, a set of four parametric mathematical models are used to demonstrate the effects of increased column cross-sections and use of shear-walls on the seismic performance of reinforced concrete structures. Architectural analyses are carried-out through three case-studies selected from the earthquake affected city of Bolu in Turkey. Cost-based analyses demonstrated that it is possible to design earthquake resistant reinforced concrete residential buildings with a 4-6% increase in the building cost and an economically acceptable 10% decrease in profits.

Creation of a New Vernacular Architecture and the Attainment of Sustainability: the Case of Akyaka Town Development
(Mdpi, 2023) Urey, Zeynep Cigdem Uysal
This study problematizes a case where the interpretation of local architectural types by a designer forms a new vernacular architecture that shapes the sphere of a newly developing small town towards one that became sustainable. The house built by Nail Cakirhan for himself in Akyaka (Turkey) opens up a new future in front of the small village of then, towards becoming a touristic center with a specific architectural language of its own. Cakirhan designs his house by interpreting the traditional houses of his hometown, Ula, which is only a few kilometers away from the village of Akyaka. The design of the house initiates the formation of a unique architectural language for Akyaka, which gradually evolves into a new vernacular architecture. Since then, this invented architectural tradition has both transformed the village into a popular touristic town and also initiated a sustainable approach due to its sensitivity for the cultural and natural assets of the context. This architectural language is protected by the master development plan now, and the town is declared as a 'slow-city' due to its culturally and environmentally sensitive character. In order to portray this development, this study will first examine Cakirhan's house in relation to its referential and actual contexts, then it will observe the development of the town of Akyaka by means of looking at Cakirhan architecture in Akyaka, the master development plan of Akyaka that protects the architectural language, and the development of the town as a sustainable, slow-city. The portrayal of the architectural development of Akyaka could demonstrate how a fairly recent architectural practice can today result in the development of a sustainable and harmonious architectural environment.

Effects of Sound Absorption Materials on Reverberation Time According To Their Positions in the Square Plan and High Ceiling Rooms
(Gazi Univ, Fac Engineering Architecture, 2021) Kurtay, Cuneyt; Harputlugil, Gulsu Ulukavak; Yaman, Muammer
In rooms with speech action, subjective and objective room acoustics parameters should be considered in the creation of acoustic performance. In this study, an evaluation has been made over the reverberation time for the speech action of the existing Iraq-Najaf Islamic University Alawiya Conference Hall. Within the scope of the study, the control of the reverberation time affecting the subjective and objective room acoustics parameters has been examined, the relationship between the reverberation time and the surface absorptions of the room have been examined. Reverberation time on existing situation was determined by making in situ measurements. In order to control the reverberation time of the existing hall, the materials selected according to the sound absorption coefficients have been positioned differently and alternative models have been developed. The reverberation times of the alternative models were determined using the ECOTECT v.5.20 computer simulation program used for acoustic analysis, and their geometric acoustics analysis was performed using the ray tracing method. By comparing the models, the surface absorptions have been analyzed to obtain the appropriate reverberation time in room for speech action. As a result of the study, the effects of the use of walls, ceiling and floor finishing materials and surface absorptions on the reverberation time have been evaluated within the scope of improvement for speech action in the halls with square plan, flat floor and high ceiling (min 6 m).

Empirical Investigation of Owner-occupiers' Reinvestments in Housing: the Case of Ankara, Turkey
(Springer, 2014) Ozdemir Sari, Ozgul Burcu
In Turkey, reinvestments in the existing housing stock are entirely dependent on households' decisions in the free market. There are no policies to consider reinvestment processes, and the body of knowledge on households' reinvestment decisions is scant. Understanding how individual reinvestment decisions are determined is vital to devise policy measures to improve the condition of the existing housing stock and neighbourhoods. In this study, an attempt is made to identify the basic motivations and factors underpinning the owner-occupants' performed and planned reinvestments in the apartment flats of Ankara. The results display that consumption considerations, particularly circumstances of necessity and urgency, are the basic motivation for undertaking reinvestment works among the surveyed owner-occupants. Higher household head age, shorter duration of occupancy, higher house value and maintained installations and infrastructure in common parts of the apartment blocks are displayed to increase the probability of having undertaken reinvestment works. Also, perception of the dwelling to be in disrepair and landscaped common outdoor space of the apartment are identified to increase the probability of having reinvestment plans for the future. The analysis suggests that policy measures are required both to trigger reinvestment capacities of households and to monitor the tendencies of reinvestments.

Environmental Strategies of Affect Regulation and Their Associations With Subjective Well-Being
(Frontiers Media Sa, 2018) Pasanen, Tytti; Repo, Veera; Hartig, Terry; Staats, Henk; Mason, Michael; Thompson, Catharine Ward; Korpela, Kalevi M.
Environmental strategies of affect regulation refer to the use of natural and urban socio-physical settings in the service of regulation. We investigated the perceived use and efficacy of environmental strategies for regulation of general affect and sadness, considering them in relation to other affect regulation strategies and to subjective well-being. Participants from Australia, Finland, Germany, Great Britain, Italy, India, the Netherlands, Portugal, and Sweden (N = 507) evaluated the frequency of use and perceived efficacy of affect regulation strategies using a modified version of the Measure of Affect Regulation Styles (MARS). The internet survey also included the Satisfaction with Life Scale (SWLS), emotional well-being items from the RAND 36-Item Health Survey, and a single-item measure of perceived general health. Environmental regulation formed a separate factor of affect regulation in the exploratory structural equation models (ESEM). Although no relations of environmental strategies with emotional well-being were found, both the perceived frequency of use and efficacy of environmental strategies were positively related to perceived health. Moreover, the perceived efficacy of environmental strategies was positively related to life satisfaction in regulating sadness. The results encourage more explicit treatment of environmental strategies in research on affect regulation.

Fostering Creative Cognition in Design Education: a Comparative Analysis of Algorithmic and Heuristic Educational Methods in Basic Design Education
(Middle East Technical Univ, 2021) Uysal Urey, Zeynep Cigdem
This research aims to examine the impact of algorithmic and heuristic educational methods in basic design education in an attempt to see their effects on the development of the creative cognition of students. The impact of educational methods in the development of creativity and creative problem-solving ability in design education has been addressed by a limited number of studies. The impact of algorithmic and heuristic educational methods in basic design education, on the other hand, has not been studied as of yet. In order to investigate this impact, this research conducts both a systematic theoretical review and a qualitative analysis on the use of algorithmic and heuristic educational methods in basic design education. The systematic theoretical review has been conducted both in the studies of design cognition and creativity and also in the studies of design education. The qualitative analysis has been carried out in the first-year basic design studio, with an attempt of making a comparison between the impacts of algorithmic and heuristic educational methods, through a creativity assessment of projects, based on the criteria of novelty and appropriateness. The analysis was made respectively on the pre-final projects of Fall 2016-2017 semester, which was carried out by means of an algorithmic educational method, and Fall 2017-2018 semester, which was carried out in line with heuristic educational method. The results of the comparative analysis have shown that both the overall novelty levels of the projects and also the average grade values were higher in the heuristic group in comparison to the algorithmic group. These results might imply that heuristic education would affect the overall creativity levels of projects in a positive way, and the students who are instructed heuristically would be able to show more exploratory behavior, generating more novel solutions than students who were instructed algorithmically.

The Interaction Between Humans and Buildings for Energy Efficiency: a Critical Review
(Elsevier, 2021) de Wilde, Pieter; Harputlugil, Timucin
Buildings consume energy for different purposes. One core function is to provide healthy and comfortable living conditions for the humans that inhabit these buildings. The associated energy use is significant: taken together, buildings are responsible for roughly 40% of the world's total annual energy consumption. This large percentage makes the built environment an important target for researchers, policy makers, innovators and others who aim to decrease energy consumption and the associated emissions of Greenhouse Gases (GHG). Unfortunately, the significant body of research on energy efficient buildings conducted since the 1970s has had only a limited impact on the overall energy use of the sector, and this remains a serious concern. The energy use of buildings shows a strong correlation with the activities of the building occupants. A key factor that makes it hard to curb building energy use is a lack of understanding of building occupant behaviour. This paper reviews research on building occupant behaviour in two stages. The first stage reviews important issues, milestones, methodologies used, building types analysed and progress achieved related to the topic, as reported in the most frequently cited papers. The second stage focuses on recent work in the area and investigates `state of the art' developments in terms of questions asked and solutions proposed. The aim is to identify problems and knowledge gaps in the field for future projection. Recent research on the topic is analysed, taking account of methodologies, building types, locations, keywords, data sampling and survey size. Based on a critical analysis of the literature, the following outcomes can be reported: research on building occupant behaviour relies strongly on quantitative methods, but studies are mostly located in the northern hemisphere and in developed and high-income countries. The dominant research topics associated with occupant behaviour are energy demand and thermal comfort, followed by retrofit and renovation. Most research focuses on technical aspects rather than socio-economic issues. Current research is mostly limited to studies of single buildings and typically lacks data-gathering standards, which makes it hard to conduct cross cultural data comparisons. Most research concentrates on individual topics, such as window, door and blind adjustments, effects of Heating Ventilating Air Condition (HVAC) systems etc. and does not provide a wider, holistic view that can be linked to social and economic factors.

The Layers of Cordoba: an Analytical Historical Study for The Effect of Religion Conflict on Architectural and Urban Features
(Vilnius Gediminas Tech Univ, 2019) Murad, Mahmoud; Batirbaygil, Mehmet; Pilehavrian, Nuran
This paper discusses Cordoba as one of the most iconic cities in human history and particularly in Europe. As part of the Andalusia region in southern Spain, Cordoba was the center of many conflicts that helped in shaping the European architecture and the urban fabric. Under the Umayyad rule, Cordoba was the largest and arguably most beautiful city in the World. However, the passage of time has not been very kind to it. Unfortunately, it has suffered from severely diminished of its historical and strategic value. This paper analysed Cordoba's history through different ages. Then, we focused on the peak of the city when it was under the Islamic rule when it became the center for culture and arts. At the end, we analysed how the city has faced a drastic architectural transformation that was carried out by the Spanish when they took control of the city during the Spanish Reconquista. We found how different cultures and religions throughout history have affected the architectural layers of Cordoba. These layers have exposed either demolish, overlap or dominate of one layer over another layer. Finally, we realized that this conflict created present Cordoba; the strong cultural, economic, touristic center in Southern Spain.

A Novel Approach for Renovation of Current Social Housing Stock Based on Energy Consumption in Turkey: Significance of Occupant Behaviour
(Taylor & Francis Ltd, 2019) Harputlugil, Timucin; Pedergnana, Matthieu; Sarioglu, Esra; Harputlugil, Guelsu Ulukavak
The goal of this research is to attempt establishing occupant behaviour profiles and how that behaviour impacts energy consumption with regard to indoor comfort levels in the current social housing stock in Turkey. The data consists of a large statistical survey that included four housing complexes situated in different climate regions in Turkey. Another more detailed survey was given to occupants of housing blocks in Ankara. Apartments were also monitored during a one-week period in summer and again in winter. All collected data were evaluated by sensitivity analysis. The results showed that occupant presence at home and operating windows had the most profound effect on internal loads and comfort levels whole year. Additionally, the transparency level of curtains, impacts the indoor temperature during the winter time. The results were used to develop a web-based tool which is going to be a guide for renovation strategies of current housing stock.

Post-Restoration Seismic Performance Assessment of a Historic Hypostyle Mosque in Anatolia (13th Century Ad)
(Elsevier, 2023) Cosgun, Turgay; Akan, Asli Er; Uzdil, Oguz; Er, Arzu; Ormecioglu, Hilal Tugba; Sayin, Baris
Assessment of structural performance under seismic effects is a very important step for restoration process of historic buildings that represent construction techniques and material characteristics of their era. This process consists of three stages namely, on-site examinations, restoration practices, and seismic analysis, and therefore, requires a multidisciplinary approach. Hypostyle structures are mostly timber-framed buildings with masonry walls on two or three facades. This construction method is a combination of Asia (wooden pillar) and Byzantine (masonry walls) techniques. The primary load-bearing system in these buildings is composed of multiple rows of wooden pillars. This paper presents post-restoration seismic assessment of a historic wooden hypostyle mosque complex constructed in 1273. This mosque complex is an important structure representing wooden hypostyle architecture in the Anatolia region of Turkey and is composed of three separate structures namely, a main mosque building, a minaret, and a tomb. Linear performance analysis, displacement-controlled nonlinear analysis, and kinematic limit analysis for failure mechanisms were conducted for the structures after the restoration. The linear performance analysis results indicated that the structures meet shear strength requirements for DD3 and DD2 earthquakes with recurrence periods of 72 and 475 years, respectively. Furthermore, according to the linear and non-linear analyses, the complex was found to satisfy performance limits for both ground motion levels in terms of inter-story drifts.
