Abstract

In today's conditions, people spend more time in buildings without compromising on comfort conditions, which has caused the amount of energy consumption to increase. Especially buildings, which are one of the sectors where energy consumption is intense, play a decisive role in the measures that can be taken to provide energy saving. Exterior facade elements have a great potential to increase the energy efficiency and environmental sustainability of buildings. In this study; the light and thermal performance evaluation of the use of phase change material (PCM) filled solar control elements (SCE) on the inner surface of triple-glazed facade systems to increase the energy efficiency of buildings is carried out. The experimental results aim to reduce the heating load of buildings in the winter season and increase the thermal resistance of facades. In the results; compared to the situation where there is no SCE in the triple-glazed system, an increase in thermal energy storage and thermal capacity was observed when the PCM filled rectangular profile inner FCE was positioned at 45o horizontally. Compared to the empty test cabin and empty SCE cases, in the experiment where the PCM filled rectangular profile inner SCE was at 45o horizontally, a 12.2% increase in the air temperature inside the cabin was observed at 40000th second in the cooling period. In the daylight value, a 27% decrease occurred compared to the empty test cabin case. It is anticipated that the study results may guide the design of energy efficient building facades for cold climate regions.

Cam cepheli binalarda FDM dolgulu güneş kontrol elemanlarının iç yüzey uygulamasının ışık ve ısıl performans analizi

Abstract

Günümüz şartlarında insanların binalarda konfor şartlarından taviz vermeden fazla zaman geçirmesi enerji tüketim miktarının giderek artmasına sebep olmuştur. Özellikle enerji tüketiminin yoğun olduğu sektörlerden biri olan binalar, enerji tasarrufu sağlamak için alınabilecek önlemlerde belirleyici bir rol oynamaktadır. Binaların enerji verimliliğini ve çevresel sürdürülebilirliğini artırmak için dış cephe elemanları büyük bir potansiyele sahiptir. Bu çalışmada; binaların enerji verimliliğini artırmak için üç camlı cephe sistemlerin iç yüzeyinde faz değiştiren malzeme (FDM) dolgulu güneş kontrol elemanları (GKE) kullanılmasının ışık ve ısıl performans değerlendirilmesi yapılmaktadır. Deney sonuçları ile de kış mevsiminde binaların ısıtma yükünün azaltılması ve cephelerde termal direnci artırılması hedeflenmektedir. Sonuçlarda; üçlü cam sistemde GKE’nın olmadığı duruma göre, FDM dolgulu dikdörtgen profil iç GKE’nın yatayda 45o ‘de konumlandırılması durumunda termal enerji depolama ve ısıl kapasitede artış gözlenmiştir. Boş deney kabini ve içi boş GKE’ları olan durumlara göre FDM dolgulu dikdörtgen profil iç GKE’nın yatayla 45o olduğu deneyde soğuma periyotunda 40000.saniyede kabin içerisindeki hava sıcaklığında %12,2’lik bir artış gözlenmiştir. Gün ışığı değerinde ise boş deney kabini olduğu duruma göre %27 oranında azalma meydana gelmiştir. Çalışma sonuçlarının soğuk iklim bölgeleri için enerji etkin bina cephesi tasarımına rehberlik edebileceği ön görülmektedir.
