    Impact of Window-To Surface Area for Different Window Glass Types and Wall Orientations on Building Energy Performance: a Case Study for a School Building Located in Izmir, Turkey
    (Yıldız Teknik Üniversitesi, 2011) Yildiz, Yusuf; Ozbalta, Trkan Goksal; Arsan, Zeynep Durmus
    The opaque and transparent surfaces of buildings have an important role in the total percentage of energy loss or gain. Heat loss or gain from windows are dependent on the window-to-wall area ratio, the window glass type, and the type of window frame used. In the concept of energy efficient design, heat loss or gain from windows should be analyzed in detail in the early stages of building design by considering local climatic conditions. This study investigates a school building located in Izmir in Turkey, a city with a hot and humid climate. Various glass types with different glazing characteristics and number of layers, located in different parts of the buildings and with different window-to-wall ratios are analyzed and compared using building the energy analysis program "EnergyPlus". Results indicate that window-to-wall area ratios, wall orientation and glass types are important factors in the building's total energy consumption. When the window-to-wall area ratio is increased from 10% to 60%, the winter heating load of the building decreases in maximum amount on the south side of the building and reduces in minimum amount on the east side of the building. When summer cooling load is investigated the highest increase in energy consumption is found on the south side of the building. On the eastern and western sides of the building the effect of increased energy consumption value remains low. When the total energy consumption (cooling + heating) is considered, it is calculated that the east and west sides have the biggest total effect and the northern wall has the smallest total effect. When low emissivity glass is used instead of double layer glass, in terms of energy consumption the building side order of effect remains the same, although actual values differ. It is therefore clear that using energy analysis programs to analyse different factors within the energy consumption of buildings will be beneficial in creating energy efficient solutions. This can be carried out in the earlier stages of the architectural design of the buildings or at the renovation stages of existing buildings.

    Investigation of Educational Buildings in Terms of Daylighting Performance
    (Yıldız Teknik Üniversitesi, 2011) Erlalelitepe, Ilknur; Aral, Duygu; Kazanasmaz, Tugce
    Educational buildings have the priority among other building types in daylight performance studies. There are several reasons for this. Classrooms which are used during the whole day should have sufficient and homogeneously distributed daylight. In insufficient daylight conditions, the use of electrical lighting increases energy consumption. Users' visual comfort should also be assured, and design incorporating natural light requires the analysis of sun protection devices in order to avoid glare and excessive heat. Also, atriums and skylights can be included in the building design with the aim of distributing light equally and in a relatively balanced manner throughout the building. However, lighting schemes are often proposed by architects and professionals who tend to make use of different design tools, and it would be pertinent to investigate whether these tools perform as desired. This study analyses daylight design principles and design elements in educational buildings. It outlines the method which has been used to analyse the daylight performance of buildings. A university building was selected for the field study. Measurements were taken in sample spaces to determine daylight performance. Utilising comparison between standard values and measured values, findings are presented in the form of tables, drawings and figures.

    A Fuzzy Logic Model To Classify Design Efficiency of Nursing Unit Floors
    (Yıldız Teknik Üniversitesi, 2010) Kazanasmaz, Tugce; Tayfur, Gokmen
    This study was conducted to determine classifications for the planimetric design efficiency of certain public hospitals by developing a fuzzy logic algorithm. Utilizing primary areas and circulation areas from nursing unit floor plans, the study employed triangular membership functions for the fuzzy subsets. The input variables of primary areas per bed and circulation areas per bed were fuzzified in this model. The relationship between input variables and output variable of design efficiency were displayed as a result of fuzzy rules. To test existing nursing unit floors, efficiency output values were obtained and efficiency classes were constructed by this model in accordance with general norms, guidelines and previous studies. The classification of efficiency resulted from the comparison of hospitals.

    The Development of Western-Type Large-Scale Consumption Areas in Turkey and Legal and Structural Regulation Efforts in Urban Retail Environments
    (Yıldız Teknik Üniversitesi, 2009) Kompil, Mert; Celik, Murat
    The retail sector has been experiencing a rapid and continuous change worldwide. There have also been profound changes in Turkey, especially after the 1980s. Both the retail sector and the urban retail environments have been altered radically. One of the most significant indicators of this change is the proliferation of western-type large-scale retail developments. Past experiences in developed countries have shown that the uncontrolled development of large-scale retail areas results in some undesired socioeconomic and physical outcomes, such as decline in the cultural and commercial activities of city centers, damage in existing retail workforce structure, and change in local retail hierarchy, nearby land uses, traffic loads and original architectural identity. Many countries have put into practice restrictive and regulatory policies to prevent these negative effects. As similar transformations have also been realized in Turkish retail environments, many institutions think that similar legal regulations must be implemented in Turkey as well. The present study investigates the ongoing retail change within the Turkish context, explores the legal and structural regulatory policies of the Organization for Economic Co-operation and Development (OECD) countries, and critically discusses the appropriate retail regulation policies for Turkey.

    Efficient Design of Nursing Unit Floors
    (Yıldız Teknik Üniversitesi, 2009) Kazanasmaz, Z. Tugce; Duzgunes, Arda
    Hospital designs aim to obtain the lowest possible construction, maintenance and operational costs together with patient satisfaction, comfort and privacy. To satisfy these needs, the efficient design of nursing unit areas becomes considerably important. This study was thus conducted to analyze planimetric design efficiency of nursing unit floors by defining certain floor areas and floor area ratios. To test existing nursing unit floors, quantitative assessments were noted in regard to their planimetric efficiency: the utility value of the built floor area, both in terms of its allocation to patient space (served), support (serving) and circulation space and the relative proportions of these. Results were presented in a comparative table. Of the 15 hospital floor plans analyzed, five satisfied minimum space requirements for patient areas, while another five were in the optimum range for circulation areas. Two were defined as the least efficient, having the lowest patient-to-circulation area ratio.

    Leed Certification: a Comparison of Contractors' Perspectives
    (Research Publishing Services, 2013) Doğan, Sevgi Zeynep; Günhan, Suat; Gerçek, Bilge; Arditi, David
    The Leadership in Energy and Environmental Design (LEED) certification system for green buildings has been used extensively in the US and has gained increased attention in developing countries as well. The related literature focuses extensively on the perspectives of owners and designers, whereas constructors' role receives less attention. One significant research is based on a survey administered to 22 contractors, who built LEED certified green building projects in the US. The survey inquired about earned LEED credits and best practices in LEED certification process regarding past experiences. The same survey was administered to seven Turkish contractors, who also built LEED certified green buildings in Turkey. The similarities and differences between US and Turkish constructors' perspectives were studied. Both groups stated that the LEED process was slightly difficult or was just straightforward. US contractors needed a lot of additional time for the LEED documentation; Turkish contractors required no extra time. LEED certification system incurred a little additional cost for US contractors; however Turkish contractors mentioned about up to 10% additional project costs. The achieved LEED credits from materials and resources, and indoor environmental quality by the two groups of contractors were highly correlated. Both groups emphasized the inclusion of LEED documentation and specifications in coordination meetings and in subcontracts to streamline the process; and emphasized the early collaboration of the entire project team for earning LEED credits.

    A Critical Review on Classification and Terminology of Scissor Structures
    (Int. Association for Shell and Spatial Structures, 2019) Maden, Feray; Akgün, Yenal; Kiper, Gökhan; Gür, Şebnem; Yar, Müjde; Korkmaz, Koray
    When the existing literature on the research of scissor structures is thoroughly investigated, it is seen that different researchers use different terminologies and classifications especially for the definition of the primary units and the motion type. Some of the studies define the whole geometry based on the geometric properties of the primary scissor units and the unit lines while some other studies define it according to the loops. All these studies use different names for similar elements. This article aims to review the literature on the classification and terminology of scissor structures and represent the state of art on the studies. Tables are represented showing all approaches in the literature. In addition, the article criticizes the missing points of each terminology and definition, and proposes some new terminology. In order to arrive at this aim, different definitions of the primary scissor units and motion types used in key studies in the literature are investigated thoroughly. With several examples, it is demonstrated that naming the scissor units according to the resulting motion type might be misleading and it is better to specify the motion type for the whole structure. A classification for transformation of planar curves is presented.

    How Myths of City Affects Architecture Via Sample of Arap Cami
    (İstanbul Üniversitesi, 2016) Gelişkan, Nil Nadire
    In order to have direct relation with past people try to settle a historical, word-of-mouth, splendid stories with place that they are living in. Having a memorable, symbolic legends makes people a part of city's collective memory. Istanbul was a significant example that not only Byzantion people controlled this capital but also it was important for others in terms of religional care and its key location between east and west. This makes Istanbul always under Islamic-Arabian attacks both because of location and religional importance. Although these attacks could not reach their aim, Arabic pilgrims searched some architectural shares to be a partner of Istanbul. Mosque is the key building to settle an partnership with Istanbul. With an partnership in other words legend was always increased. This intention also affects architecture somehow with some symbolic buildings that Arap Cami is important one because of having claim of the first Islamic construction in Istanbul. This study seeks to understand reasons of naming a Latin church which probably was constructed on an old Byzantion church firstly as a mosque of Mesleme by giving some Islamic symbolic meanings. In order to get some clues about what makes Istanbul as legendary Arabs and also Muslims, how they tried to gain ownership of this capital not truly but metaphorically or symbolically. Starting from Arap Cami as case study archives, records and travellers scripts will be major research sources for this study. Historians of Istanbul had tendency to mention about this city as God's city with regards to being Constantinopolis or Istanbul. Because settling of Istanbul at the beginning held by emperor who represented as God on earth. For Muslims conquering of this city has significant and symbolic importance in consequence of prophet's words: 'Such a glorious commander who conquered Istanbul, such a glorious soldier who conquer Istanbul'. Arap Cami is important because of having an origins speculations tries to settle desiring relation with Constantinopolis. Anonymous mouths who established legends and myths put in to contact with both their roots and anyone who would listen. Purpose of study is investigating effects of origin speculation in terms of architecture.

    Through City Miniatures of Matrakci Nasuh Analyzing Bitlis With Regards To History of Architecture
    (İstanbul Üniversitesi, 2016) Gelişkan, Nil Nadire
    Bitlis is an important historical city that was settled on important trade roads between Asia and Mediterranean as a kind of market bridge since the beginning of history. Because of having such important position between mountains as a valley of Bitlis river makes this city precious on a very high plateau at the end of Eastern Taurus. With the victory of Malazgirt in 1071 city is frequented by the Turkish army after that point Seljuks became the ruler of Bitlis. Since that time Bitlis owned the essence of open-air museum even today because of having so many Seljuks monuments. The importance of historical background and vital location of city has not been reflected in the historical sources as anticipated. Domestic and foreign travelers who visits Bitlis somehow keep travel diaries which are reference guides today in order to have an idea about the situation of the city at that time, events, places and people in light of the author's owns style and vision. In this context, especially Evliya Celebi who visited Bitlis in 1655 is at the first place. Travelers records have been documented as visual map through Matrakci Nasuh. Between 1533 and 1536 Kanuni Sultan Suleyman organized a campaign and through their journey all ranges were they crossed he noted a book which is called as Beyan-i Menazil-i Sefer-i Irakeyn Suleyman Han or Description of the Stages of His Imperial Majesty Sultan Suleyman's Campaign in Two Iraqs (the 'two Iraqs' of the title refer to areas that are today Western Iran and Iraq) has consisted of 90 pages, 107 miniatures and 25 illustrated texts. Matrakci Nasuh has recorded representations of the cities making them almost appropriate exactly to their origin. In this context, this study would be the first study of Bitlis which is aimed to build city inventory of Bitlis in 16th century view collaborating with miniature of Matrakci Nasuh. Method of the study as depicted through the city which is the only document of the 16th century, structures which are still standing today, overlaid with the technical drawings of buildings and photographs describing the current situations will be discussed with the travelers records from past.
