Abstract

This study explores the potential of using woodcarving ventilation panels to enhance natural ventilation (NV) in buildings, particularly in extreme climate conditions in two different locations: Johor, Malaysia, and Szombathely, Hungary. The main aim is to assess how these panels contribute to airflow dynamics and temperature regulation within buildings. The research employs Computational Fluid Dynamics (CFD) simulations to model airflow and temperature distribution in identical building models subjected to high wind speeds and temperatures, simulating worst-case scenarios. The findings reveal that while Johor experiences moderate wind speeds resulting in steady but less dynamic airflow, Szombathely benefits from stronger winds, producing more effective ventilation and cooling. These results suggest that woodcarving panels can improve airflow and thermal comfort but are more effective in areas with higher wind speeds. The study concludes that while NV is beneficial, integrating HVAC systems is essential for maintaining optimal comfort in extreme conditions.
