Hava sızdırmazlığının konvansiyonel pencerelerin ortalama ısıl yalıtım performansındaki rolü

Year 2017, Volume: 8 Issue: 1, 159 - 174, 01.03.2017

Abstract

Binalarda yapı elemanlarının ısıl direnç yeteneklerinin iyileştirilmesi
ve yapı elemanlarından gerçekleşen enerji kayıplarında ciddi bir role sahip
olan hava sızdırmazlığının maliyet etkin yöntemlerle minimize edilmesi güncel
düşük/sıfır karbon bina standartlarının yakalanabilmesi açısından büyük önem
arz etmektedir. Bina yapı elemanları arasında pencereler infiltrasyon esaslı
ısı kayıplarına hatırı sayılır ölçüde etki ederler. Cam yüzeylerden gerçekleşen
infiltrasyon kaynaklı ısı kayıpları özellikle eski pencerelerde ve özensizce
gerçekleştirilen montajlarda azımsanmayacak değerlere ulaşabilmektedir.
Literatürde hava sızdırmazlığının konvansiyonel pencerelerden olan enerji
kayıplarına etkisini belirlemeye yönelik bazı teşebbüsler olmasına rağmen, elde
edilen sonuçlar arasında pek çok çelişkiler mevcuttur. Bu yüzden bu
araştırmada, hava sızdırmazlığının konvansiyonel hava dolgulu çift camlı
pencerelerin ortalama ısı transfer katsayısına (U-değeri) olan etkisi kapsamlı
bir deneysel çalışma ile incelenmektedir. Testler Nottingham’da bulunan ve
konvansiyonel hava dolgulu çift camlı pencerelerle restore edilmiş karakteristik
Birleşik Krallık mimarisine sahip bir konutta gerçekleştirilmektedir. Konuttaki
pencerelerden bir tanesi ısıl yalıtım testlerine tabi tutulmaktadır. Test
penceresinin bir kanadı mükemmel hava sızdırmazlığı temin eden özel saydam bir
örtü ile ön yüzeyden kaplanırken, diğer pencere kanadı sıradan durumu temsil
edecek şekilde olduğu gibi bırakılmaktadır. Ölçümler Nisan 2016’da yapılmakta
ve dinamik co-heating test metodu ile hava sızdırmaz pencere kanadının
U-değerindeki iyileşme miktarı değerlendirilmektedir. Elde edilen sonuçlara
göre, hava sızdırmazlığı ve saydam örtü ile hava sızdırmaz pencere kanadının iç
cam yüzeyi arasında oluşan sera etkisine bağlı olarak özellikle gündüz
saatlerinde etkisi belirginleşen ters ısı akıları neticesinde, hava sızdırmaz
pencere kanadının ortalama U-değeri sıradan pencere kanadına göre kayda değer
ölçüde düşük çıkmaktadır. Sıradan pencere kanadının ortalama U-değeri 2.67 W/m2K
iken, hava sızdırmaz pencere kanadının ortalama U-değeri 1.79 W/m2K
olarak belirlenmektedir. Buradan hareketle, hava sızdırmazlığı temin edilen
konvansiyonel pencerelerde enerji kayıplarının %33 mertebesinde
azaltılabileceği sonucuna varılmaktadır.
