Performance Analysis of Green Wall Ventilation Blocks Toward Sustainable Building Design

The integration of green wall systems into building envelopes has gained significant attention as a passive design strategy to enhance thermal comfort and promote sustainable architecture. This study presents a performance analysis of environmentally friendly ventilation blocks designed specifically for green wall applications in tropical climates. The ventilation blocks were fabricated using eco-friendly materials, including a mixture of recycled aggregates and natural binders, to reduce the environmental footprint of the building components.Airflow behavior and thermal performance were simulated using computational fluid dynamics (CFD)-based software to assess their effectiveness in enhancing natural ventilation and indoor air quality. Several design variations of the ventilation blocks were tested to examine the influence of geometry and porosity on airflow rate, pressure drop, and air temperature reduction.The results indicate that certain block configurations significantly improve air circulation while contributing to energy savings by reducing the need for mechanical ventilation. This research supports the development of sustainable building components that align with green architecture principles and offers insights for architects and engineers in optimizing passive ventilation strategies through material innovation and simulation-based design.
