Natural ventilation allows outdoor air to move through buildings using wind pressure and temperature differences.
Cross-ventilation can be encouraged through appropriately positioned windows and openings.
In suitable climates, this improves airflow and reduces reliance on mechanical cooling.
However, outdoor temperature, humidity, air quality, and noise must also be considered.
Building Orientation
Proper building orientation can reduce excessive solar exposure.
In many Indian locations, controlling direct sunlight on east- and west-facing walls is particularly important because low-angle sunlight can be difficult to shade.
Orientation should also consider prevailing winds, site conditions, and seasonal temperature variations.
Shading Devices
Architectural shading elements help protect buildings from excessive sunlight.
Common solutions include:
- Deep roof overhangs.
- Horizontal and vertical shading fins.
- Traditional jali screens.
- Shaded balconies.
- Pergolas and covered walkways.
Well-designed shading can reduce indoor heat gain while maintaining daylight and ventilation.
