Özellikle dış cephelerde, güneş ışığınınortama yansıtılması ve soğurulması, mimari yapının iklimsel koşulları (mevsimsel sıcaklık ortalaması,güneşli gün sayısı, ortalama en yüksek sıcaklık, ortalama güneşlenme süresi vb.) baz alındığında, enerjiverimliliği ve ısısal konfor açısından oldukça önemli sonuçlar doğurabilmektedir.Bu çalışma kapsamında, gerek yurt içi ve gerekse yurt dışında yüksek ticari öneme sahip farklı renk,doku ve yüzey (cilalı, honlu ve kumlamalı) özelliklerine sahip 5 farklı karbonat kökenli (kireçtaşı, rekristalizemermer, traverten) doğal taş türüne ait numuneler kullanılmıştır. Kuru ve doygun durumdagüneş ışığı yansıma ve ısıl yayılım değerleri ölçülerek, güneş ışığını yansıtma indeks değerlerihesaplanmıştır. Kuru ve doygun durum için hesaplanan güneş ışığını yansıtma indeks değerinin, yüzeyözelliklerindeki değişime bağlı olarak önemli derecede değişimler gösterdiği gözlenmiştir.</p></abstract>
