Architects can use natural ventilation to respond to architecture context in hot and humid climates in the following ways:
1. Cross-ventilation: Architects can design buildings with openings on opposite sides of the building to facilitate cross-ventilation. This allows for fresh air to flow through the building, expelling hot air and reducing humidity levels.
2. Stack effect ventilation: This works by creating a convection current which draws hot air up and expels it through vents placed at the top of the building. This is particularly effective in tall buildings.
3. Facade shading: Shading devices such as louvers, awnings, and screens can be used to diffuse and block direct sunlight from entering the building. This reduces the amount of heat and glare entering the building, which in turn reduces the need for artificial cooling systems and increases natural ventilation.
4. Roof gardens: Incorporating green roofs can help to cool the building by providing insulation and shading, reducing the amount of heat absorbed by the building. Additionally, vegetation can help to filter air pollutants and regulate humidity levels.
5. Courtyards: Courtyards can be used to create a microclimate that provides natural ventilation and passive cooling. By surrounding the building with a courtyard, air can circulate freely through the space and reduce humidity levels.
6. Operable windows: Architects can design buildings with operable windows to allow occupants to control the amount of air and natural light entering the building. This also facilitates natural ventilation and can reduce the need for mechanical ventilation systems.
