Project information
The PCM Facade focuses on addressing the issue of energy inefficiency and indoor comfort in modern buildings, particularly those with glass facades. Although curtain walls are visually appealing, they often perform poorly in terms of thermal regulation. This can lead to unstable indoor temperatures, increased energy consumption, and reduced occupant comfort. To tackle this problem, a modular facade system was designed to integrate Phase Change Materials (PCMs) into the field of retrofitting. These materials store and release heat as they transition between solid and liquid states. By doing this, they regulate indoor temperatures and reduce the need for mechanical heating and cooling systems. Our design exceeds current PCM systems by ensuring high light transmittance. Through research and testing, an optimized shape for the encapsulation was designed, that enhances gradual and quick phase changing. The built prototypes emphasizes the P-shaped encapsulation, modular design, and improved performance. For real-world application of this design, further research would focus on: optimizing the PCM transparency; improving the module on shape and durability; and refining the attachment system for retrofitting.
