An investigation on daylighting performance in educational institutions

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 wind...

Evaluation of structural irregularities based on architectural design considerations in Turkey

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 ...

Çift Cidarlı Cephelerdeki Etkin Mimari Tasarım Kararları

In architectural discourse, it is possible to notice a rising interest in building skin configurations which promise to help minimizing the loss of energy while maximizing its gain. In parallel, it is possible to see that the use of doubleskin glass facades globally pervades. All over the world double-skin facade applications multiply day by day. This technology is still quite new in Turkey and it is not possible to find many applications or researches done on this subject. For this reason, architects and engineers should be focused on the designs solutions providing energy savings. The design of DSF depends on various architectural decisions. In this study, effective design decision parameters on energy performance of DSF systems will be discussed in a comprehensive way in architectural perspective by reviewing previous studies.
