Abstract

In the pursuit of sustainable urban development, the integration of natural ventilation principles with architectural design has emerged as a promising strategy to enhance indoor environmental quality, reduce energy consumption, and promote occupant comfort in mixed-use developments. This review article delves into the intricate relationship between natural ventilation strategies and building form, elucidating how their synergy can contribute to creating healthier and more sustainable built environments. Natural ventilation systems, harnessing wind and buoyancy forces, present a compelling alternative to traditional mechanical ventilation systems, offering significant energy savings and improved indoor air quality. The integration of controlled ventilation, building density considerations, wind and buoyancy forces, urban context integration, and design optimization mechanisms plays a pivotal role in promoting natural ventilation efficacy within mixed-use developments. Building form, encompassing layout, orientation, and design elements, interact synergistically with natural ventilation strategies to optimize airflow patterns, indoor air quality, and occupant comfort. Through strategic orientation, placement of openings, and incorporation of passive cooling techniques, developers and architects can capitalize on prevailing winds and thermal buoyancy to create comfortable, energy-efficient indoor spaces. Furthermore, the incorporation of atria, courtyards, and voids within building designs facilitates stack ventilation, while optimized form and façade design enhance wind pressure and airflow distribution. The benefits of natural ventilation in mixed-use developments extend beyond energy efficiency and occupant comfort, encompassing improved indoor air quality, enhanced connection to nature, and increased property value. Empirical research and theoretical analysis underscore the complexity of natural ventilation systems and the need for an all-encompassing strategy tailored to the specific needs of mixed-use developments. Recommendations for optimizing the synergy between natural ventilation and building form include integrating natural ventilation strategies effectively, embracing passive cooling techniques, adopting mixed-mode building design, incorporating passive design elements, implementing green roofs and vertical gardens, designing flexible building layouts, and leveraging smart building technologies.
