Analysis of Synergies in Comfort, Energy and Cost by Removing the Exhaust Air Between Glazing and Interior Roller Blind

This paper presents an in-depth investigation of the Active Cavity Transition (ACT) Facade. It needs less space than double skin facades or closed cavity facades and is designed to enhance the thermal comfort, particularly under conditions where exterior shading is impractical. Through experimental measurements and simulations conducted, we analyze the thermal dynamics of the ACT Facade. The findings demonstrate that the ACT Facade effectively lowers the temperatures of the interior roller blind. The lower temperatures increase the probability that the occupants extend the screen which as a positive impact on the energy efficiency of the building. Additionally, the study explores the potential of utilizing exhaust air for heat pump applications, revealing challenges related to seasonal temperature variations. Overall, the results highlight the ACT Facade's promising role in optimizing building performance, providing valuable insights for future architectural and engineering innovations in energy-efficient facade design.
