Which type of ventilation system relies on natural forces such as wind and buoyancy to move air through a building?
Mechanical Ventilation
Natural Ventilation
Mixed Mode/Hybrid
Forced Ventilation
What is the primary mechanism by which wind-driven ventilation occurs in buildings?
Through mechanical fans
By wind pressure moving air through openings
By temperature differences inside and outside
Through air conditioning systems
How does air flow through a building in wind-driven ventilation?
From areas of low pressure to high pressure
From areas of high pressure to low pressure
From the roof to the basement
From the basement to the roof
What is the effect of locating openings in both positive and negative pressure regions of a building?
It disrupts the airflow pattern
It creates a suitable flow pattern through the building
It increases the building's temperature
It decreases the building's temperature
Which factors affect the distribution of pressure in wind-driven ventilation?
The color of the building
The terrain
The number of windows
The type of roofing material
How does wind velocity change with height according to the typical wind profile?
It decreases with height.
It remains constant with height.
It increases with height.
It fluctuates randomly with height.
How can wind pressure enhance stack effects in natural ventilation systems?
By increasing the size of the building
By placing stack outlets in the negative region above the roof
By reducing the number of windows
By using thicker walls
Which of the following is not a mode of natural ventilation?
Day ventilation
Night ventilation
Day and night ventilation
Mechanical ventilation
How does wind speed affect natural ventilation in buildings?
It decreases airflow rate and pressure difference.
It increases airflow rate and pressure difference.
It has no effect on airflow rate and pressure difference.
It only affects the temperature inside the building.
