Abstract

Industrialisation causes migration from rural to urban areas. This situation increases the consumption of raw materials and energy in building stocks, CO2, greenhouse gases and global warming. The solution is the implementation of sustainable and energy-efficient design strategies. Ensuring physical environmental comfort conditions in buildings - such as thermal, visual, acoustic, and indoor air quality -requires high energy usage. This study assesses the potential for improving the south façade of the Gebze Technical University (GTU) Rectorate Administrative Building in a temperate-humid climate through double-skin façade system. The study aims to evaluate the performance of the glass type and insulating gases used between the glass layers in terms of heating and cooling energy consumption. Rhinoceros/Grasshopper and Honeybee programs were used for the analysis. As a result of the improvements, the system reduced energy consumption for heating and cooling. Low-E glass and argon gas used in the improvement system were key factors.

Ilıman-Nemli İklimde Mevcut Bir Ofis Binasının Çift Kabuk Cephe Sistemi ile iyileştirmesinde Cam Bileşenlerinin Enerji Etkinliğinin Değerlendirilmesi

Abstract

Sanayileşme, kırsal alanlardan kentsel bölgelere göçü tetiklemektedir. Bu durum, bina stoklarında hammadde ve enerji tüketimini arttırarak, CO2, sera gazları ve küresel ısınmayı yükseltmektedir. Çözüm olarak sürdürülebilir ve enerji verimli tasarım stratejilerinin uygulanmasıdır. Binalarda termal, görsel, akustik ve iç hava kalitesi gibi fizik ortam konfor koşullarının sağlanması yüksek enerji kullanımı gerektirmektedir. Bu çalışma, ılıman-nemli iklim bölgesindeki Gebze Teknik Üniversitesi (GTÜ) Rektörlük İdari Binasının güney cephesinin çift kabuk cephe sistemi ile iyileştirilme potansiyelini değerlendirmektedir. Çalışma, cam türünün ve cam katmanları arasında kullanılan yalıtım gazlarının performansını ısıtma ve soğutma enerjisi tüketimi açısından değerlendirmeyi amaçlamaktadır. Analiz için Rhinoceros/Grasshopper ve Honeybee programları kullanılmıştır. Yapılan iyileştirmeler sonucunda, sistem ısıtma ve soğutma enerji tüketimini azaltmıştır. İyileştirme sisteminde kullanılan Low-E cam ve argon gazı kilit faktörler olmuştur.
