A comparative review of environmental concern prioritization: LEED vs other major certification systems
(2015) Süzer, Özge; 27418
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 þ 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.

A comparison of the cognitive actions of designers in geometry-based and parametric design environments
(2020) Tünger, Çetin; Taşlı Pektaş, Şule; 272043
Purpose - This paper aims to compare designers' cognitive behaviors in geometry-based modeling environments (GMEs) and parametric design environments (PDEs). Design/methodology/approach - This study used Rhinoceros as the geometric and Grasshopper as the parametric design tool in an experimental setting. Designers' cognitive behaviors were investigated by using the retrospective protocol analysis method with a content-oriented approach. Findings - The results indicated that the participants performed more cognitive actions per minute in the PDE because of the extra algorithmic space that such environments include. On the other hand, the students viewed their designs more and focused more on product user relation in the geometric modeling environment. While the students followed a top-down process and produced less number of topologically different design alternatives with the parametric design tool, they had more goal setting activities and higher number of alternative designs in the geometric modeling environment. Originality/value - This study indicates that cognitive behaviors of designers in GMEs and PDF-s differ significantly and these differences entail further attention from researchers and educators.

Providing the needed and indispensable steady, quality and safe energy is one of the most important issues today. Wind energy is one of the most important renewable energy source. Wind energy has found uses much more in water pumping and obtaining electricity in rural areas until last years. Today, wind energy has taken its place in the energy sector as an alternative source of energy production. High-density building arrays within a city, the combination of indoor and outdoor spaces with different purposes effect wind flow and acceptable wind comfort. In urban areas, wind energy and wind comfort are important requirements. Not only in new urbanisation areas but also for existing urban areas and city centers acceptable wind comfort plays an important role among and around buildings. When viewed from this angle, the aim of this study is enlightening the building aerodynamics, wind effect and wind energy in urban environment, and also giving information about how to analyze the wind comfort and design criteria in dense urban areas.

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

A practical approach to performance-based building design in architectural project
(Routledge Journals, Taylor & Francis LTD, 2019) Sayın, Selçuk; Çelebi, Gülümser
The aim of this study is to develop an approach that can enhance and contribute to the practical applicability of performance-based building design in architectural projects. The need for such an approach is based on the current lack of a practical application for performance-based design in architectural projects, despite the numerous studies conducted in this regard to date. The approach has been applied in a commercial building project designed by an architectural firm in Konya. The performance evaluation of the design developed in accordance with the requirements of the client/builder and the restrictions of regulations was carried out using IES VE 2014 software at a specific phase of the design process. Through this building performance simulation tool; the thermal protection of the envelope/heat loss and solar gain, thermal comfort (temperature, humidity), air quality (freshness), daylight and glare levels were evaluated for the selected spaces in the building, and following the evaluation, new design proposals were put forward to improve the design so as to meet the performance goal.

A Review based on OLED Lighting Conditions and Human Circadian System
(2023) Avcı, Ayşe Nihan; Akbay, Saadet; 237970; 21742
Light is a form of energy that affects the human sleep cycle, working hours, alertness, productivity, and well-being. As one of the essential environmental factors, lighting requires extensive research to understand the human-environment interaction. Earlier studies reveal that various artificial lighting technologies are utilized to investigate the human circadian system; experiments employing solid-state lighting (SSL) sources are still being conducted to determine how the human circadian system is affected. Due to the advantages of OLED (organic light-emitting diode) lighting, there is a need to enhance this form of artificial lighting in an indoor environment. This paper focuses on a literature review on artificial lighting sources, particularly OLED lighting, used from the past to the present. This article also discusses how OLED lighting can influence the human circadian system in terms of different characteristics of lighting in an indoor environment. © 2023, Gruppo del Colore?

A taxonomy of indoor acoustic environments and sound source preference in shopping centres
(Institute of Noise Control Engineering, 2020) Erçakmak, Beyza Uğur; Dökmeci, Papatya Nur; 214925
As part of soundscape research, sound source classification and taxonomy studies play an important role in relation with contextual experience and user perception. Although, outdoor acoustic environments have been studied in detail, published and standardized in the literature, taxonomy studies on indoor acoustic environments are still at its preliminary phase and should be progressed. This study concentrates on shopping centre indoor acoustic environments and presents a preliminary proposal on the indoor sound source taxonomy of such indoor public spaces. The presented taxonomy and the structured classification of the sound sources lead to the preparation of a structured surveying protocol. Thereby, the sound source preference in the case shopping centre has been studied through this structured indoor soundscape preference assessment questionnaire, which is applied to 23 participants. The indoor sound source taxonomy lead to the identification of the sound sources to be included in the structured preference assessment questionnaire. 24 sound sources have been assessed through a bi-polar 6-point forced-choice rating scale. The results of the questionnaire have led to the identification of the most and least preferred sound sources in shopping centres, which can act as key elements in the design phase of such public enclosed environments.

Occupational safety and health (OHS) education in universities has an important role in developing and improving safety cultures in the workplace. Safety education is essential for improving necessary OSH skills, culture and knowledge, so do architects, urban planners, interior architects whose duties are regarded as the design, planning and execution of construction projects in high-risk sectors. As a consequence, there has been increasing recognition that safety education courses in the architecture faculties should have participative learning methods and resources. In order to increase preparedness for any potential future health crises parallel to the “Vision Zero” approach in work-related deaths, a new EU Strategic Framework was announced by the European Commission. The course described and proposed here aimed to raise awareness about OHS by teaching risks related to working environments, basic issues, basic legislation within the scope of OHS. It also aimed to cover professional liability with respect to OHS, and risks and hazards in the construction sector, as well as helping participants to analyze and evaluate the risks in workplace. This article’s primary objective is to identify an innovative safety education model of the “occupational health and safety course” with a “Vision Zero” approach.

An interdisciplinary sound source categorization framework for environmental sound design
(2021) Kitapçı, K.; Özdemir, D.
One of the objectives of architectural design is to create multisensory environments. The users are under the influence of a wide variety and intense perceptual data flow when users experience a designed space. Architects and environmental designers should not ignore the sense of hearing, one of the most important of the five primitive senses that allow us to experience the physical environment within the framework of creative thinking from the first stage of the design process. Today, auditory analysis of spaces has been studied under architectural acoustics, soundscapes, multisensory interactions, and sense of place. However, the current sound design methods implemented in the film and video game industries and industrial design have not been used in architectural design practices. Sound design is the art and application of making soundtracks in various disciplines, and it involves recognizing, acquiring, or developing auditory components. This research aims to establish a holistic architectural sound design framework based on the previous sound classification and taxonomic models found in the literature. The proposed sound design framework will help the architects and environmental designers classify the sound elements in the built environment and provide holistic environmental sound design guidelines depending on the spaces' functions and context. © INTER-NOISE 2021 .All right reserved.

AN INVESTIGATION OF SOUND SOURCES IN SMART HOUSES FOR IMPROVED MACHINE-TO-HUMAN COMMUNICATION
(2023) Alkan, A.; Dökmeci Yörükoğlu, Papatya Nur; 214925
This study aims to investigate the ever-evolving indoor soundscapes of smart houses by classification of the sounds emitted from smart devices. Nowadays, communication is no longer limited to person-to-person. Smart devices frequently communicate with users by verbal or tonal notifications. Therefore, acoustic characteristics of smart houses, especially reverberation time and background noise levels, have increased importance in achieving improved and lossless signal transfer and speech intelligibility. It is hypothesized that most houses are unsuitable for effective tonal and verbal communication with smart devices regarding acoustical conditions. Within the scope of the study, the devices found in the smart technology market were investigated. The sounds emitted from the identified devices were then classified according to their communicative nature (verbal/tonal), designability, customizability, and cause (i.e., intentional or consequential). The acoustic requirements for effective communication with the individual smart devices were analyzed in addition to the resulting holistic indoor soundscape of the smart houses The results of the study will help architects, interior architects, and other environmental designers to improve the quality of communication while guiding future research to understand indoor soundscapes of smart houses. © 2023 First author et al.

Analyzing Natural Lighting Conditions from the Perspective of Biophilic Design in Indoor Office Environments
(IOP, 2022) Doğan Karaman, Gülşah; Avcı, Ayşe Nihan; 319194; 237970
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.

Analyzing the compliance and correlation of LEED and BREEAM by conducting a criteria-based comparative analysis and evaluating dual-certified projects

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.

Hayat fiziki olarak içinde geçtiği için, mimarlığın insanlar üzerinde güçlü bir etkisi vardır. Mimarlık eserlerinin ifadesi zamana, yer ve toplumlara göre değişiklikler gösterir. Bu değişiklikler gözlemlenmiş ve genel olarak “üslȗp” diye adlandırılmışlardır. Sükȗnet ve durağanlığın hâkim olduğu Eski Çağlar’da üslȗpların uygulanması çok yavaş olmuştur. Üslȗp değişimlerinin hızı teknolojik gelişmelere bağlı olarak giderek arttı, o kadar ki bir insan ömrü içindeki değişimlerin hızını takip etmek çok güç. İçinde yaşanılan dönem içerisinde oluşan üslȗpları ayırt etmek güçtür fakat geçmiş dönemler incelendiğinde görebilmek kolaydır. Bununla birlikte, gündelik hayatı kontrol eden günlük nesneler, yapılar ve hatta yerleşimler incelendiğinde, belli bir üslȗbu tanımlayabilmek mümkündür. Her dönem insan eliyle yaratılmış her şey üzerinden gözlemlenebilecek belli bir estetik anlayışı yansıtır. Bu noktadan hareketle, 20. yüzyıla hükmeden temel üslȗp Modernizm olarak adlandırılabilir. Öte yandan mimaride ve tasarımda Modern Hareket kendi içinde çeşitlemeler ya da dallar içerir. Bunlardan bazıları belirgin ve güçlüyken bir kısmı da gölgede kalmışlardır. Art Deco bu ikinci gruptandır ve bu nedenle bu makalenin konusu olarak seçilmiştir.

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 design 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 Eldem, 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
(2021) Kitapçı, Kıvanç; Akbay, Saadet; 275153; 21742
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.

Color Perception in Correlated Color Temperature of Led Lighting

Color and light are inseparable entities that are the essential design factors in the field of interior architecture. When the light changes, the perceived color appearance of a surface within an interior environment also changes. The change in color perception is not only related to the type of a light source or the intensity of illumination, but also to the correlated color temperature (CCT) of a light source. The aim of this study is to understand how different CCTs of light-emitting diode (LED) lighting influence the color perception. A study is conducted to compare the perceptive color tendencies for inherent colors under two different CCTs of LED lighting, i.e. warm (2700º K) and cool (4000º K). In the study, Natural Color System (NCS) is utilized as a color notation system to reveal the possible tendencies and patterns concerning the relationship between the inherent and perceived colors. The general tendencies for the perceived colors revealed similar patterns in the nuance (i.e. blackness and chromaticness) color area for each inherent color and showed dispersion on the hue color area under the CCTs of both 2700º K and 4000º K LED lighting.

CONCEPTUAL FRAMEWORK FOR A DECISION-MAKING MODEL BASED ON THE ANALYTIC HIERARCHY PROCESS (AHP) TO SELECT THE BEST PUBLIC PRIVATE PARTNERSHIP (PPP) MODEL FOR AIRPORTS
(New Zealand Acad Applied Research LTD, 2017) Mohammed, Ali Omar; Harputlugil, Timuçin; 40295
The adoption of public-private partnerships (PPPs) as a strategy for infrastructure projects, such as airports, highways, bridges, water supplies, and telecommunication, has been implemented in developed and developing countries with a number of obstacles. Based on this stance, critical success factors (CSFs) of public-private partnership projects and the selection of appropriate PPP models are critical issues that need to be analyzed. A multidisciplinary review of the literature on the critical success factors of public-private partnerships projects reveals the lack of a comprehensive decision-making model for selecting an appropriate PPP model. This paper presents a conceptual framework for a decision-making model to select the best PPP model considering CSFs for developing countries. The model is expected to be used for infrastructure projects, mostly for airports. The decision-making model is structured on the Analytic Hierarchy Process and sensitivity analysis. The decisionmaking model is expected to be adopted as a tool and contribute to decision makers for selecting the best fit PPP model for airports in order to enhance projects successfully.
