Çift cidarlı cephelerin akış ve enerji modellemesi yapılarak performanslarının nicel olarak incelenmesi ve sundukları mimari olanakların nitel sorgulaması
(2015) Başaran, Tahsin; Erek, Aytunç; Ersoy, Ufuk; İnan, Tuğba; Kutluay, Pınar
Sürdürülebilir, enerji etkin bina arayışı, mimaride gün geçtikçe belirleyici bir rol kazanmaktadır. Bu yaklaşım ulusal ve uluslararası boyutta bina performans standartlarını tanımlamakta ve dolayısıyla mimari tasarım ve sürecinin gözden geçirilmesini gerektirmektedir. Bu bağlamda enerji kayıplarını minimuma indirmeyi ve kullanılan enerjiden maksimum düzeyde faydalanmayı hedefleyen yapı kabuğu sistem arayışı üzerine yapılan araştırmalar mimari söylemde gittikçe önemli bir yer kazanırken, yapı sektöründe çift cidarlı cam cephe sistemlerinin kullanımı küresel ölçekte yaygınlaşmaktadır. Bu projede öncelikle çift cidar cepheye ilişkin niteliksel bir kavram sorgulaması, tarihsel gelişme süreci ışığında gerçekleştirilmiştir. Projenin deneysel boyutu ise iç ve dış ortam şartlarının yaratıldığı iki mekân arasındaki çift cidar cephe uygulamasında farklı çalışma koşulları için akış ve ısı transferi analizlerini içermektedir. Bu bağlamda çift cidar cephe kavitesindeki doğal ve zorlanmış taşınım koşulları altında, güneş ışınımı etkilerinin göz önüne alınıp alınmadığı durumlar için, kararlı ve zamana bağlı analizler sayısal ve deneysel olarak gerçekleştirilmiştir. Ayrıca kavitede farklı perfore saç uygulamasının yarattığı basınç düşümünün etkileri de deneysel olarak incelenmiştir.

An Investigation on Daylighting Performance in Educational Institutions
(Emerald Group Publishing Ltd., 2013) İnan, Tuğba
Purpose: The purpose of this research is to investigate natural illumination properties of one of the classrooms in the School of Architecture at Izmir Institute of Technology, located in Turkey, which is the northern hemisphere. Design/methodology/approach: In this study, the definitions of the basic terms in daylighting, such as daylight factor, illuminance, glazing ratio, are given first. Then, a luxmeter and a lighting simulation software, Velux, are used in order to calculate variable lighting factors during daytime, at different storeys, at different directions, for the classes. Velux is a proprietary software and it enables natural lighting analysis practically. Findings: Chosen classrooms are examined regarding their having sufficient natural illumination. The height of windows from the floor is changed, and the resultant effects on natural lighting in the classrooms are determined by using the lighting simulation program, Velux. The study shows that daylight factor and illumination near the window decreases as the height of the window above the floor increases. However, the illumination increases away from the window, giving greater uniformity to the lighting. At the same time, the usable depth of the classroom increases. The tall and narrow windows bring the daylight near themselves. Social implications: Practical window design decisions can help architects to provide effective and healthy natural lighting for interiors. Originality/value: Adjustment of the dimensions of the windows is important in order to balance the energy consumption of buildings. This study investigates natural lighting depending on both experimental measurements and simulation software, Velux.

Evaluation of Structural Irregularities Based on Architectural Design Considerations in Turkey
(Emerald Group Publishing Ltd., 2011) İnan, Tuğba; Korkmaz, Koray
Purpose: The purpose of this research is to show significant points which can be used in the architectural design process by investigating the basic principles of earthquake resistant design (ERD) in a deductive format and to contribute to the architectural perception in ERD. Design/methodology/approach: First, the structural irregularity types are examined depending on the rules defined in the Turkish Earthquake Code, 2007 (TEC). Then, architectural design failures related to earthquake resistance of buildings under earthquake loading are visualized and solution suggestions in literature are described in detail by supported drawings. Findings: The problems causing structural irregularities are investigated deeply with given solutions in literature. It is obtained that the significant factors affecting the earthquake performance of structures are: architectural form, structural configuration, slenderness ratio, the location and rate of floor openings, projection rates and symmetry, rigidity and strength differences between floors, short columns, pounding effect. Social implications - The practical design decision rules can contribute to the phenomena of earthquake resistant architectural design and can encourage adoption of these rules in building industry. Originality/value: This study aims to gain an understanding of the problems in projects in terms of structural irregularities, and then manage to solve the problems using problem-oriented approaches. The suggested solutions can be adopted and applied to future projects for designing earthquake resistant buildings.
