Abstract
Adaptive facades take a prominent position in modern architecture, representing a critical evolution in building design. Their significance lies in their ability to respond to changing environmental conditions. These facades integrate advanced materials, technologies, and design strategies that enable buildings to adapt to varying climates, to optimize energy efficiency, and enhance occupants’ comfort. Through modulating their properties like transparency, shading, and insulation, adaptive facades effectively control heat gain, natural light entry, ventilation, and reducing reliance on mechanical systems for cooling. Beyond energy conservation, these facades offer a user-centric approach, ensuring a harmonious indoor environment conducive to productivity and well-being.
This research explores opportunities for reducing energy consumption and improving thermal comfort through adaptive facades technologies, in office buildings in Cairo, Egypt. The study focuses on various adaptive facades typologies, technologies and investigates their impact on environmental performance. The adaptive facades technologies are categorized into more than category, such as: switchable glazing, dynamic shading devices, and solar active facades.
Through simulations and analysis, the study assesses the annual energy consumption, heat gain through glazing, thermal comfort, operative temperature, and annual CO2 production for each type of adaptive façade technologies. The findings show the potential of these technologies by reducing energy consumption by up to 32.1%, minimizing heat gain by up to 87.6%, and improving occupant comfort by 30%. and decreased CO2 emissions by 33.6%.
This research provides valuable insights into how adaptive facades can address energy challenges and enhance the built environment in hot-arid climates, facilitating more sustainable and comfortable office buildings. Recommendations include integrating adaptive facades into building codes and offering policy incentives for sustainable building practices. Future research should explore aspects like visual comfort, daylighting, integration with renewable energy sources, long-term performance assessment, and cost-benefit analysis.
