Heat Gain Estimation with Window Film Application in Some Major Cities of Turkiye during Summer and Related Cost Estimation

Öz

Many disasters occur around the world in connection with global warming. Many studies are conducted to find ways of decreasing levels of emissions of greenhouse gases. Reducing consumption of fossil fuels is the most common method used to decrease emissions. This study focusses on estimation of heat gain in a model room with given characteristics of window filming. The results are given comparatively for eight types of windows including clear and tinted windows and additionally three types of filming coated on both types. Heat gain is estimated for summer days adaptively by using the models taking into account the location of the city, the position of windows, the building volume and moisture. The heat gain and final room temperature for clear window is taken as a reference and other seven calculations are observed in terms of differences between heat gains in order to evaluate and compare their effectiveness. Cost analysis is performed in terms of electric consumption, carbon emission and price for characteristics including location, temperature and facade of the sample room.

Anahtar Kelimeler

Türkiye’nin Büyük Şehirlerinde Yaz Aylarında Cam Filmi Kullanımı ile Isı Kazancı Kestirimi ve Maliyet Analizi

Öz

Küresel ısınma ile bağlantılı olarak dünya çapında birçok felaket meydana gelmektedir. Sera gazlarının emisyon seviyelerini azaltmanın yollarını bulmak için birçok çalışma yürütülmektedir. Fosil yakıt tüketiminin azaltılması emisyonları azaltmak için kullanılan en yaygın yöntemdir. Bu çalışmada belirli cam filmi özelliklerine sahip bir model binada sağlanacak ısı kazancının kestirimi gerçekleştirilmiştir. Sonuçlar, saydam ve renkli cam üzerine kaplanmış üç film tipi için karşılaştırmalı olarak verilmiştir. Isı kazancı kestirimi, şehir, cam, bina ve nem özellikleri dikkate alınarak yaz günleri için uyarlamalı olarak yapılmıştır. Filmsiz saydam cam için elde edilen son oda sıcaklığı referans olarak alınmış ve diğer yedi tipte cam için kestirim bu referansa göre yapılmıştır. Örnek binanın konumu, sıcaklığı ve cephesi gibi özellikler dikkate alınarak elektrik tüketimi, karbon emisyonu ve fiyat açısından maliyet analizi yapılmıştır.
