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; 36110; 05.02. Mimarlık; 05. Mimarlık Fakültesi; 01. Çankaya Üniversitesi
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.

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.; 190116; 01. Çankaya Üniversitesi
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.

The Interaction Between Humans and Buildings for Energy Efficiency: a Critical Review
(Elsevier, 2021) de Wilde, Pieter; Harputlugil, Timucin; 40295; 05.02. Mimarlık; 05. Mimarlık Fakültesi; 01. Çankaya Üniversitesi
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.

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; 26110; 40295; 05.02. Mimarlık; 05. Mimarlık Fakültesi; 01. Çankaya Üniversitesi
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; 154406; 05.02. Mimarlık; 05. Mimarlık Fakültesi; 01. Çankaya Üniversitesi
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.

Seismic Evaluation of a Renovated Wooden Hypostyle Structure: a Case Study on a Mosque Designed With the Combination of Asian and Byzantine Styles in the Seljuk Era (14th Century Ad)
(Elsevier, 2021) Akan, Asli Er; Basok, Gulsah Celik; Er, Arzu; Ormecioglu, Hilal Tugba; Kocak, Sevilay Zamur; Cosgun, Turgay; Sayin, Baris; 154406; 05.02. Mimarlık; 05. Mimarlık Fakültesi; 01. Çankaya Üniversitesi
Wooden hypostyle structures are primarily built using timber-framed construction types, surrounded by masonry walls on two or three facades. This construction technique is a combination of Asian (wooden frame) and Byzantine (masonry wall) techniques. The primary load-bearing system in these structures consists of multiple rows of wooden pillars. This paper focuses on the restoration of a historical wooden hypostyle mosque constructed in 1366. The mosque is a crucial example of wooden hypostyle tradition in the Anatolia region of Turkey. The study consists of four steps: field survey, lab tests, restoration practices, and seismic performance analyses for the examined structure. The on-site examination includes the visual inspection of material deterioration and the analyses of obtained samples from different places of the structure. Moreover, a building survey was carried out using three-dimensional laser scanning. Secondly, a laboratory study was performed using the samples gathered from the structure. The physical tests revealed that while the stone sample taken from the minaret had the highest porosity, the stone sample represents the west facade displayed the lowest porosity. Accordingly, the water absorption capacity of the stone sample taken from the west facade was the lowest. On the other hand, among samples, this stone sample had the highest wet and dry density. In the third step, the renovation process of the mosque considering its originality is presented. Lastly, the seismic performance level of the renovated structure is obtained using three analyses: linear, pushover, and kinematic approaches. Story drift ratios of the structure at the performance points for three earthquake ground motion levels meet the target performance requirements. Considering the realistic behavior of the material, the vulnerability of the main structure against the maximum credible earthquake is revealed in terms of tensile and shear stresses. The seismic vulnerability of the minaret is also determined in terms of both tensile and shear stresses and the story drifts ratios in both analysis types. We believe that the structural restoration processes presented in this paper to bring back a deteriorated historical mosque to its original form will provide a comprehensive approach to the literature.

Sustainable Environment Education in Pre-School Pupils
(Modestum LTD, 2018) Ozburak, C.; Batirbaygil, M.H.; Uzunoğlu, S.S.; 167451; 05.02. Mimarlık; 05. Mimarlık Fakültesi; 01. Çankaya Üniversitesi
"Sustainable Environmental Education" at early ages is important for creating environmental awareness. When the content of current environmental education curriculums at schools in the North Cyprus is analyzed, it is seen that only the natural environment elements are covered. Whereas environment is divided into two that are natural and the built environment. Besides the recognition and protection of the natural environment, sustainable built elements play an important role. The aim of this study is to identify through measuring the deficiency of preschool children's level of awareness of "sustainable built environment". The study was administered to 134 five year-old preschool children at a private school in the city of Nicosia by using the qualitative approach. During the study, "Interviews" were arranged and 17 questions were asked to the children. The children's level of knowledge on "sustainable built environment" was measured through a pre-test. According to the results obtained, the children are familiar with natural elements such as the trees, animals and water around their environment but are not familiar with basic building elements or related sustainable systems such as wind turbine (25.37%), solar panels (13.43%) and green roof (8.20%). These results show us the the lack of "sustainable built environment education". © 2018 by the authors; licensee Modestum Ltd., UK.

Tourism-Led Adaptive Reuse of the Built Vernacular Heritage: a Critical Assessment of the Transformation of Historic Neighbourhoods in Cappadocia, Turkey
(Routledge Journals, Taylor & Francis Ltd, 2023) Buke, Fatma Gul Ozturk; 05.02. Mimarlık; 05. Mimarlık Fakültesi; 01. Çankaya Üniversitesi
Since the last quarter of the twentieth century, increased tourism in traditional settlements have led to the adaptive reuse of built vernacular heritage to serve the tourism industry. The adaptive reuse of historic buildings is considered a conservation strategy and an alternative to new constructions in historic environments. Nevertheless, the adaptive reuse of built vernacular heritage and its socio-spatial impacts have not yet been sufficiently investigated. To fill the gap, this paper, focuses on Cappadocia, Turkey, where adaptive reuse of individual vernacular houses has recently paved the way for the transformation of an entire neighbourhood, the historic neighbourhood of Kayakapi, into a 'holiday village.' This study argues that traditional settlements and communities in Cappadocia have been subjected to 'gentrification' and so-called 'Disneyfication.' Such historic environments are facing controversial physical interventions, detached from local communities and devoted to a single function, namely tourism, becoming 'stereotypical and depersonalised.' The study further argues that the current situation is incompatible with international heritage and conservation policies. Correspondingly, to reveal the potential conflicts, the recent revitalisation project of the historic neighbourhood of Kayakapi in Cappadocia is examined as a case study.

Understanding Intangible Aspects of Cultural Heritage: the Role of Active Imagination
(Routledge Journals, Taylor & Francis Ltd, 2018) Alves, Susana; 05.02. Mimarlık; 05. Mimarlık Fakültesi; 01. Çankaya Üniversitesi
Despite an undoubted awareness of the intangible aspects of culture in heritage studies, scholars continue to base their understanding of intangible heritage according to rationalist theories of perception, which accept only a single mode of perception-that which is bound to the empirical, sensorial and terrestrial world. How are we to appropriately value and safeguard practices such as 'shamanic voyages' to the worlds of spirits, engage with the symbolic narratives of creation myths and recognise the significance of religious rituals and mystical experiences, if we do not consider the ways of knowing, being and doing of diverse cultural groups in the first place? A meaningful analysis of intangible dimensions in heritage needs to consider the role and ontological status of human imagination. By drawing on the theory of imagination proposed by Ibn 'Arabi and discussed by Corbin, this paper enquires about the role of imagination in people's perception of intangible heritage. With a view to redress the symbolic function in human perception, the paper concludes by proposing the use of 'active imagination' as a method in heritage management to understand how intangible experiences and values are associated with the physical aspects of heritage.
