Energy Efficient Construction Materials for Arctic Homes

Abstract

Residential sector of Alaska accounts for about 8% of the total national energy consumption. Space heating accounts for 72% of the total residential energy consumption. Many studies are conducted to model building energy consumption in different climates. However, there are very few studies about the most efficient building constructions for Alaska climate. In this study, heating energy consumption of a single detached dwelling in Anchorage and Fairbanks Alaska is modelled by means of eQUEST software. The results show that most energy efficient roof, wall and door construction materials are wood. House with dark colored roof and wall are estimated to consume 2% less energy for heating compared to light colored ones. Most energy efficient window glazing is concluded to be 12 mm argon filled triple glazing. In addition, the effect on the energy consumption of direction of doors and windows is also investigated.

Arktik Evleri için Enerji Verimli Yapı Malzemeleri

Abstract

Alaska’da konut sektörü, toplam ulusal enerji tüketiminin yaklaşık % 8’ini oluşturmaktadır. Toplam konut enerji tüketiminin % 72’sini alan ısıtması oluşturmaktadır. Farklı iklimlerde bina enerji tüketimini modellemek için birçok çalışma yapılmıştır. Bununla birlikte, Alaska iklimi için en verimli bina yapıları hakkında az sayıda çalışma bulunmaktadır. Bu çalışmada, Alaska Anchorage ve Fairbanks’daki bir müstakil konutun ısıtma enerji tüketimi, eQUEST yazılımı vasıtasıyla modellenmiştir. Sonuçlar, enerji tasarruflu en fazla çatı, duvar ve kapı inşaat malzemelerinin ahşap olduğunu göstermektedir. Koyu renkli çatı ve duvarları olan konutların açık renkli olanlara kıyasla ısıtma için % 2 daha az enerji tükettiği tahmin edilmiştir. Enerji tasarrufu en yüksek pencere camının, 12 mm argon boşluklu üçlü cam olduğu sonucuna varılmıştır. Buna ek olarak, kapı ve pencerelerin yönünün enerji tüketimi üzerindeki etkisi de araştırılmıştır.
