About Natural Ventilation
Natural ventilation is the process of supplying air to and removing air from an indoor space without using mechanical systems. It refers to the flow of external air to an indoor space as a result of pressure differences arising from natural forces. Natural and assisted ventilation is important in Indian buildings as majority of the buildings are not air-conditioned.
During BEEP charrettes, particularly for residential buildings, the designs are appraised for natural ventilation, and design changes are suggested to improve natural ventilation. BEEP has designed an innovative assisted ventilation system for the affordable housing project at Rajkot. BEEP is now working on developing a design tool (software) based on openfoam, which will assist building designers in the design of natural ventilation systems.
