Numerical Investigation of Wind-Driven Cross-Ventilation on a Low-Rise Residential Building
Natural ventilation is an essential element of sustainable buildings as well as a promising solution for mitigating indoor air quality (IAQ) issues such as those related to the spread of COVID-19. The current study analyzes wind-driven cross-ventilation efficacy for a low-rise residential building with complex geometry and internal partitions consistent with typical units. A high-resolution computational fluid dynamics (CFD) simulation is carried out using a 3D steady Reynolds-Averaged Navier–Stokes (RANS) approach with a realizable k-ε turbulence closure. Microclimate parameters include different wind speeds and wind directions for a configuration with openings on all four sides of the building. The results indicate that air changes per hour (ACH) increase with windward opening area, and the number of ACH has a linear relationship with the wind velocity. Furthermore, adequate natural ventilation requires rooms to have a minimum of two openings to influence airflow and enhance IAQ.
