Heat transmission through the building envelope crucially affects the use of energy needed to maintain thermal comfort within buildings. Therefore, significantly reducing this energy demand is essential for decarbonizing the building sector. Despite extensive research on adaptive façades, their practical application remains limited, and current building simulation programs cannot yet model adaptive façades, as existing tools do not support adaptive building envelopes. Enhancing these simulation tools to accommodate this capability is necessary. To further this endeavor, there is a concerted effort to demonstrate that adaptive façades not only contribute to energy savings but also offer significant advantages for the comfort of building occupants. A simulation module is being utilized to investigate which thermodynamic processes can be accurately represented. Particular attention will be paid to the thermodynamic processes underlying the adaptive mechanisms of the building envelope. By gaining a deeper understanding of these processes, it is intended to precisely quantify the potential of adaptive façades. This approach will be tested in various scenarios, including winter, summer, and transition seasons, to enable a comprehensive assessment of the performance of adaptive façades under different climatic conditions. These research efforts are crucial for developing advanced simulation-based tools that allow realistic representation and evaluation of adaptive façade systems, thereby providing a solid foundation for their practical implementation and contributing further to the decarbonization in the building sector.
