Effects of LED Lighting on Visual Comfort with Respect to the Reading Task
(2017) Avcı, Ayşe Nihan; Memikoğlu, İpek; 237970; İç Mimarlık
Lighting systems in interior architecture need to be designed according to the function of the space, the type of task within the space, user comfort and needs. Desired and comfortable lighting levels increase task efficiency. When natural lighting is inadequate in a space, artificial lighting is additionally used to support the level of light. With the technological developments, the characteristics of light are being researched comprehensively and several business segments have focused on its qualitative and quantitative characteristics. These studies have increased awareness and usage of artificial lighting systems and researchers have investigated the effects of lighting on physical and psychological aspects of human in various ways. The aim of this study is to research the effects of illuminance levels of LED lighting on user visual comfort. Eighty participants from the Department of Interior Architecture of Çankaya University participated in three lighting scenarios consisting of 200 lux, 500 lux and 800 lux that are created with LED lighting. Each lighting scenario is evaluated according to six visual comfort criteria in which a reading task is performed. The results of the study indicated that LED lighting with three different illuminance levels affect visual comfort in different ways. The results are limited to the participants and questions that are attended and used in this study.
Bir Erken Cumhuriyet Dönemi Yapısında Doğal Aydınlatmaya Dair İç Mekan Aydınlık Düzeylerinin İncelenmesi: Ankara Refik Saydam Hıfzıssıhha Enstitüsü Kimyahane ve Bakteriyoloji Binası Laboratuvarları Örneği

Geçmişten günümüze estetik, fonksiyon, sürdürülebilirlik, kullanıcı-mekân ilişkisi gibi konulardaki değişimlere tanıklık eden Ankara,dinamik yapısıyla kendinden söz ettirmiş ve çeşitli tartışmalara konu olmuştur. Bu değişimlerle birlikte yeni talepler ortaya çıkmış,ihtiyaçları karşılayabilmek için farklı fonksiyonları bir arada bulunduran yeni binaların inşa edilmesiyle, kentin çehresi gün geçtikçedeğişmiştir. Mimari tartışmalara konu olan yapılar, genellikle 1920-1950 yılları arasında yapılmış Cumhuriyet dönemi yapılarıdır. Öteyandan geçmişte inşa edilen binalarda, iç mekân tasarımında kullanıcı için önemli olan tasarım ilkelerine hangi boyutta yaklaşıldığıfarklı disiplinlerde merak konusu olmuştur. Merak konusu olan tasarım ilkelerinden biri de aydınlatmadır. Bu çalışmanın amacı,geçmişte inşa edilen bir yapıda, bina tasarımından ziyade, iç mekân özelliklerinin analiz edilmesi ve benzer çalışmaların artırılmasıdır.İç mekân analizi için, tasarım ilkelerinden biri olan aydınlatma seçilmiştir. Çalışmada, Erken Cumhuriyet dönemi yapılarından biriolan ve Sıhhiye'de bulunan Refik Saydam Hıfzıssıhha Enstitüsü Kimyahane ve Bakteriyoloji Binası'nın günümüze kadar bir kısmıylakorunabilen laboratuvarlarındaki doğal aydınlatmaya dair aydınlık düzeyleri araştırılmıştır. Bulgular, standartlarda belirtilen değerlerlekarşılaştırılıp yorumlanmıştır. Çalışmadaki bulgular ve yorumlar, ölçüm yapılan günler ve saatle sınırlandırılmıştır.

Evaluating effectiveness of led and oled lights on user visual comfort and reading performance
(2021) Avcı, Ayşe Nihan; Memikoğlu, İpek; 237970; İç Mimarlık
In interior architecture, one of the main purposes of light is to create comfort-\rable and functional spaces according to user needs. Light provides individuals to\runderstand, get information for visual tasks and it affects how they experience\rand behave in the environment. Desired illuminance levels are required for visual\rcomfort and task efficiency. This study analyzes the effects of different illuminance\rlevels of light emitting diode (LED) and organic light emitting diodie (OLED)\rlights on user visual comfort and reading performance. An experiment was con-\rducted with eighty interior architecture students at Çankaya University. Six light-\ring scenarios were created with LED and OLED lighting sources that assessed\rsix visual comfort criteria. The experimental setting consisted of three different\rilluminance levels, as 200, 500 and 800 lx. The results revealed that different illu-\rminance levels were found more comfortable for different visual comfort criteria,\rbut the illuminance level of 500 lx was visually more comfortable than the other il-\rluminance levels. The illuminance level of LED 200 lx was visually more comfort-\rable than LED 800 lx. OLED light was found visually more comfortable than LED\rlight. In addition, participants read slower under the illuminance level of LED\r200 lx. It was concluded that illuminance levels of light effect user’s visual comfort\rand reading performance. This study provides a basis to recommend the preferred\rilluminance level for LED and OLED light during a reading performance.
Experience with clay in the basic design education
(2015) Memikoğlu, İpek; Sümengen Berker, Olgu; Tolun, Elif; İç Mimarlık
Basic Design is a first year fundamental course that is taught in different disciplines such as architecture, design and fine arts. Basic Design introduces the basic concepts and principles of design and enables students to develop mental and manual skills to cope with design problems. It allows students to structure and articulate two and three dimensional spatial compositions in different media. Clay as a plastic material was chosen to develop their creativity in making 3D abstract design works. For four semesters clay was integrated into the Basic Design courses of Interior Architecture and Architecture departments of Çankaya University in Ankara, Turkey. During this period, 270 students produced 3D design works consisting of clay and/or metal based on different design concepts. The aim was to broaden their viewpoints while designing with such a plastic material and create sensual artistic works by using an extra material that contrasted with the plasticity of clay. The final products showed that students were able to use clay and/or metal as effective tools in representing their design ideas. The outcome of this design experience showed that students can utilize ceramic/clay in their design projects.
