Özet:

 Prefabricated facade panels are building components that evolve with technology and offer a wide range of material possibilities. These panels can be constructed using wood, metal, concrete, or terracotta-based materials and are designed based on three concepts: massive, sandwich, and frame. In recent years, as sustainable design takes the spotlight, it is crucial to consider not only energy consumption and carbon emissions from heating and cooling but also the carbon emissions associated with the materials used in construction. This study aims to analyze prefabricated facade panels with wooden structures in terms of operational and embodied energy, providing guidance to designers in selecting suitable concepts. Calculations were conducted on a selected sample building. Compared to the traditional Baghdadi wall, the sandwich panel scenario with PUR insulation material resulted in energy savings of 53.21 percent. The massive CLT panel, which lacks insulation material or cladding, showed the lowest energy gain at 15.91 percent. Considering the overall emissions in the analysis, it has been determined that embodied carbon emissions have a greater impact than operational carbon emissions. Therefore, it is essential to emphasize the significant role of material selection for prefabricated facade panels in reducing carbon emissions.

 Prefabrike cephe panelleri teknoloji ile gelişen ve malzeme olanakları ile çeşitlenen yapı elemanlarıdır. Ahşap, metal, beton veya pişmiş toprak esaslı taşıyıcı malzemelerden üretilebilen bu panellerin üç tasarım konsepti bulunmaktadır: masif, sandviç ve çerçeve. Sürdürülebilir tasarımın ön planda olduğu son yıllarda ısıtma ve soğutma kaynaklı enerji tüketimi ve karbon emisyonlarının yanı sıra binalarda kullanılan malzemelerin ürettiği karbon emisyonları da önemli rol oynamaktadır. Bu çalışma, ahşap taşıyıcıya sahip masif, sandviç ve çerçeve prefabrike cephe panellerinin operasyonel ve gömülü enerji açısından incelenmesini ve karşılaştırılmasını amaçlamaktadır. Bu kapsamda seçilen örnek yerel bina üzerinden hesaplamalar yapılmıştır. Binanın sahip olduğu Bağdadi duvar ile karşılaştırıldığında, PUR yalıtım malzemesine sahip sandviç panel senaryosu 53.21 oranında enerji tasarrufu sağlamıştır. En az enerji kazancı ise 15.91 oran ile herhangi bir yalıtım ve kaplama içermeyen masif CLT panelde görülmüştür. Yapılan analizde toplam emisyon miktarları dikkate alındığında, gömülü karbon emisyonunun operasyonel karbon emisyonundan daha etkili olduğu tespit edilmiştir. Bu doğrultuda prefabrike cephe panellerinde yer alacak malzeme seçiminin önemi dikkat çekmektedir.
