Using an overhead high-volume, low-speed (HVLS) fan’s bi-directional airflow and elevated air speed is a powerful way to improve ventilation, thereby reducing the concentration of airborne pathogens through dilution. Occupant comfort can be assured in applications ranging from non-conditioned industrial spaces to commercial buildings.

Water is the most significant factor in the premature deterioration of our buildings. Excessive moisture accumulation on porous materials can lead to water penetration, freeze-thaw damage, efflorescence, cracking, and façade soiling.

With an appropriate strategy and design, a naturally ventilated structure can be comfortable for all occupants, including those in a multi-storey building. This article examines how natural ventilation fits into mixed-mode setups, safety considerations for building occupants, and esthetic features, and also explores how it can relieve engineers of issues associated with pairing an off-the-shelf actuator with a standard window.
