The energy takes an important shares in the nowadays classifications on the country development level. The energy consumption rate is considered as an effective parameter in all the future planning of the countries. Accordingly, scientific studies are important to reduce energy consumption. In this study, the effects of using insulation and phase change material (PCM) on the floors were investigated on energy efficiency and comfort conditions. In a building consisting of basement, ground floor and two normal floors, different scenarios were studied for simultaneously heated and unheated zones. In these scenarios, the effects of these parameters on the heat loads, zone temperature and energy consumption were investigated using three different types of flooring (uninsulated, insulated, and insulated and including PCM). According to the findings obtained from the study, the heat load of the zones decreased with the use of the insulation and PCM on the floor and ceiling. At the same time, it was determined that the thermal comfort conditions were improving as the zone temperatures were closer to the set point temperature. The results show that the use of insulation and PCM in floors and ceilings decrease the annual energy consumption and provides a significant increase in the energy efficiency.

Günümüzde ülkelerin gelişmişlik düzeylerine ilişkin tüm sınıflandırmalarda enerji önemli bir yer tutmaktadır. Ülkelerin geleceğe yönelik yaptığı bütün planlamalarda enerji kullanım oranı etkin bir parametre olarak göz önüne alınmaktadır. Buna bağlı olarak enerji kullanımının düşürülmesi amacıyla yapılan bilimsel çalışmalar önem kazanmaktadır. Bu çalışmada, ara kat döşemelerinde yalıtım ve faz değiştiren malzeme (FDM) kullanılmasının enerji verimliliği ve konfor koşulları üzerindeki etkileri incelenmiştir. Bodrum, zemin ve iki normal kattan oluşan örnek bir binada eş zamanlı olarak ısıtılan ve ısıtılmayan ortamlardan oluşan farklı senaryolar üzerinde çalışma yapılmıştır. Bu senaryolarda yalıtımsız, yalıtımlı ve yalıtıma ek FDM içeren bir katmanın olduğu üç farklı döşeme tipi kullanılarak, bu parametrelerin ortamların ısı yüklerine, ortam sıcaklığına ve enerji kullanımına etkileri incelenmiştir. Çalışmada elde edilmiş olan bulgulara göre; döşeme ve tavanda yalıtım ve FDM kullanılması ile ortamların ısı yükü düşmektedir. Aynı zamanda ortam sıcaklıklarının ayar sıcaklığına daha yakın olması ile birlikte ısıl konfor koşullarının iyileşmekte olduğu belirlenmiştir. Çalışma sonuçları göstermektedir ki; döşeme ve tavanlarda yalıtım ve FDM kullanımı, yıllık enerji kullanımını aşağıya çekmekte ve enerji verimliliğinde önemli bir artış sağlamaktadır.
