Enhanced Natural Ventilation: Improving Air Quality with Building Code Compliance
Natural ventilation relies on airflow through openings designed for wind, temperature differences and the layout. Choosing a wall material or increasing window count does not establish adequate ventilation.
Climate and air quality
Review temperature, humidity, noise, outdoor pollution and control of openings. Conditions may require mechanical or mixed-mode ventilation. Natural ventilation is not always the lowest-energy or healthiest option.
Requirements and performance
Establish requirements from the adopted code and occupancy, checking outdoor-air needs, flow paths and pollutant extraction. A single opening-area percentage cannot be applied universally or attributed to a standard without its edition, scope and conditions.
