Abstract

Enerji, modern yaşamın temel itici güçlerinden biridir ve insan hayatında hayati bir öneme sahiptir. Gelişmiş toplumlarda, enerjinin etkin ve verimli kullanımı bireylerin konforunu artırırken, özellikle fosil yakıtlara dayalı enerji üretiminin çevresel etkilerini azaltmaktadır. Bu bağlamda, binalarda enerji tasarrufu büyük bir önem taşımaktadır; çünkü yapıların enerji tüketimi toplam enerji kullanımının önemli bir kısmını oluşturmaktadır. Yapı malzemelerinde faz değiştiren malzeme (PCM) kullanımı, binaların termal performansını artırmak için etkili bir yol olarak öne çıkmaktadır. PCM'ler, faz değişimi sırasında ısıyı emer ve/veya salarlar, böylece iç mekân sıcaklığını dengeleyerek klima gibi iklimlendirme sistemlerinin enerji tüketimini azaltmaktadır ve bina içinde daha istikrarlı bir ısıl ortam sağlamaktadır. Bu da hem enerji maliyetlerinde tasarruf sağlamakta hem de çevresel etkileri azaltmaktadır, böylece sürdürülebilir bir yaşam alanı oluşturmaktadır. Bu makalede binalarda PCM kullanımı konusunda çalışılarak son 5 yılda gerçekleştirilen PCM katkılanmış duvar harç malzemelerinin binaların ısıl özelliklerine etkisi araştırılmıştır. Sonuçlar faz değiştiren malzeme kullanımının umut verici çıktılar oluşturduğunu yansıtmakta ve yapıların ısıl özelliklerini iyileştirdiğini göstermektedir.
