Analysis of the Embodied And Operational Energy of Wood-Based Prefabricated Panels Produced with Different Design Concepts According to Vernacular

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.
