TL;DR
This study explores using windcatchers in Egyptian social housing to improve ventilation and reduce energy use through natural airflow.
Contribution
The study introduces orientation-specific windcatcher placement strategies to optimize natural ventilation in social housing.
Findings
A single windcatcher in a northwest-oriented apartment improved ventilation by 7%.
Three windcatchers in a southwest-oriented apartment improved ventilation by 45.7%.
Dual windcatcher configurations in southwest-oriented apartments nearly matched triple configurations in performance.
Abstract
This study investigated the potential of integrating windcatchers into Egyptian social housing buildings to enhance natural ventilation and improve indoor thermal comfort, thereby reducing energy consumption used to enhance airflow inside residential spaces of residential communities, which is considered an important aspect of sustainable urban development that aims to counteract climate change. Computational Fluid Dynamics (CFD) simulations validated by site measurements were conducted on two distinctly oriented apartment models. The northwest-oriented apartment demonstrated a 7% improvement in natural ventilation rate with a single strategically placed windcatcher in the bedroom. The southwest-oriented apartment showed a remarkable 45.7% improvement when equipped with three windcatchers distributed across the living room and bedroom spaces. The results revealed that strategic…
