Natural Ventilation

Natural Ventilation is a passive environmental design strategy that uses the forces of wind pressure, buoyancy, and thermal difference to move fresh air through buildings without mechanical assistance, reducing energy consumption, improving indoor air quality, and creating the connection to outdoor climate that occupants instinctively find more comfortable than sealed, conditioned interiors. Effective natural ventilation design requires a deep understanding of local climate, prevailing wind patterns, building orientation, and the placement of openings — cross-ventilation through opposing facades, stack ventilation through vertical shafts and atriums, and the use of wind towers and courtyards that are time-tested strategies from vernacular architecture worldwide. As a core component of bioclimatic design and sustainable architecture, natural ventilation is experiencing renewed interest as architects respond to the energy and wellbeing imperatives of the climate crisis, designing buildings that breathe with their environment rather than against it.
