Abstract

Bu çalışmada, çift kabuk ve geleneksel tek kabuk cephe sistemlerindeki ısı transferi zamana bağlı tek boyutlu yaklaşımla ele alınarak, deneysel ve sayısal olarak incelenmiş ve cephelerin bina enerji performansına özellikle de ısıtma enerjisine etkisi araştırılmıştır. Bu kapsamda tek kabuk ve kutu tipi tampon bölge kullanımındaki çift kabuk cephelerdeki ısı transferinin hesaplanması için bölgesel analiz yöntemi aracılığı ile kullanıcı davranışı ve alüminyum doğrama elemanı etkisi dikkate alınarak matematiksel model kurulmuş ve kurulan model deneysel olarak doğrulanmıştır. Deneysel çalışma Ege Üniversitesi İnşaat Mühendisliği Bölümü binasının güney cephesinde yer alan, tek kabuk ve çift kabuk cephe kuruluşlarına sahip ofis mekanlarında 2017 Ocak ayı içerisinde ölçümler alınarak gerçekleştirilmiştir. Ardından, doğrulanan model, İzmir İli için, yıl içerisinde meydana gelen ısı transferini aylık ortalama günlük zaman dilimlerinde incelemek üzere kullanılmıştır. Akdeniz ikliminin hüküm sürdüğü İzmir İlinin 10 yıllık ortalama iklim verileri kullanılarak, tek kabuk ve çift kabuk cephe sistemlerinde ısıl performansın değişimi yıl içerisinde iklime bağlı olarak araştırılmıştır. Çift kabuk cephelerin ısı yalıtımı işlevini görerek iç ortamda meydana gelebilecek çok yüksek ve çok düşük sıcaklık değerlerini dengelediği

EXPERIMENTAL AND ANALYTICAL EXAMINATION OF THE EFFECT OF DOUBLE SKIN FAÇADE SYSTEM ON BUILDING THERMAL PERFORMANCE

Abstract

In this study, heat transfer in conventional single skin façade and double skin façade system was studied experimentally and numerically by using one dimensional time dependent approach and the effects of the façade systems on building energy performance especially heating energy was investigated. In this context, a mathematical model considering user behavior and window aluminum frame element effect was build by zonal analysis method to calculate the heat transfer in single and box type closed cavity double skin façade systems, and build model was experimentally verified. Experimental study was conducted in office spaces having single and double skin façade systems in Ege University, Civil Engineering Building’s south façade in January 2017. Next, verified model was used to study the heat transfer in the façade systems for İzmir’s climatic condition by using monthly average daily data. The change in thermal performance of single and double skin façade systems due to the climatic condition during a year was investigated by using the 10 year average climate data of İzmir (Mediterranean climate). It was found that double skin façade system acts as an insulator preventing extreme indoor temperature values, thus contributing to the indoor comfort level against changing outdoor conditions.
