Why is ventilation necessary in a house in the tropics?

Building ventilation is necessary in providing acceptable indoor air quality (IAQ). It is a process of supplying fresh air and removing or diluting indoor pollution concentration. ... Thus, stack effect ventilation is highly depending on the size of the openings which will influence the air pressure inside the building.

Why is natural ventilation necessary?

Natural ventilation promotes a healthier lifestyle. For instance, the oxygen from fresh air can enhance your heart rate, blood pressure, and energy levels. It strengthens your immune system. It also makes you feel relaxed and refreshed thanks to higher serotonin levels.

What does natural ventilation depend on?

Natural ventilation relies on the wind and the "chimney effect" to keep a home cool. Natural ventilation works best in climates with cool nights and regular breezes. The wind will naturally ventilate your home by entering or leaving windows, depending on their orientation to the wind.

Why is the sun important in tropical building design?

In the tropics, a building should be oriented so that the majority of walls and windows can easily be shaded from direct sun, while allowing maximum airflow and input of natural light (see Figure 1).

What is building orientation in tropical region?

The optimum orientation of residential building area in tropical climate is facing east or north and its major openings can greatly influence the solar heat gain[10]. North and east orientation has less direct solar direction towards the building envelope.

Why are ventilators so important?

A ventilator pumps air—usually with extra oxygen—into patients' airways when they are unable to breathe adequately on their own. If lung function has been severely impaired—due to injury or an illness such as COVID-19—patients may need a ventilator. It is also used to support breathing during surgery.

What is house ventilation?

Ventilation. Ventilation refers to the exchange of indoor and outdoor air. Without proper ventilation, an otherwise insulated and airtight house will seal in harmful pollutants, such as carbon monoxide, and moisture that can damage a house. Proper ventilation helps keep a home energy-efficient, safe, and healthy.

What will happen if your house is having poor ventilation?

Polluted air in combination with poor ventilation causes dry throat and eyes, concentration disorders, fatigue, headaches, shortness of breath, poor sleep, drowsiness, dizziness.

Why is tropical design important?

Tropical architecture can be regarded as a type of green building applicable specifically for tropical climates, using design to optimally reduce buildings' energy consumption, particularly the cooling load. ... These design solutions allow windows to remain open for natural ventilation in a building during rainy season.

How is tropical climate?

Tropical climates are characterized by monthly average temperatures of 18 ℃ (64.4 ℉) or higher year-round and feature hot temperatures. Annual precipitation is often abundant in tropical climates, and shows a seasonal rhythm to varying degrees. ... The annual temperature range in tropical climates is normally very small.

Why is climate responsive architecture?

The goal of climate-responsive architecture is to create a comfortable interior while reducing the building's reliance on artificial energy. A climate-responsive building design reflects the weather conditions in the precise area where the building is constructed.

What type of houses are built in the tropical zone?

Healthy Homes in Tropical Zones — ingvartsen. Early nomadic shelters, including caves, animal skin tents and igloos, were used for protection against the wind, rain, snow, sunlight and other forces of nature. These basic homes also provided defence against predators and were used to store a few important possessions.

What are the orientation criteria for Indian tropical climate?

Exterior orientation

The shading should be adequate enough in case of summers and in winters the shade should be transformable enough to let the sun in. The larger building face should face NORTH – SOUTH. Orientation along the west is never preferred in case of hot and dry climatic regions.

How building form and orientation is important for climate responsive building?

Orientation also plays an important role with regard to wind direction. The building form determines the volume of space inside a building that needs to be heated or cooled. ... In hot & dry regions and cold climates, building's shape needs to be compact to reduce heat gain and losses, respectively.

Why are ventilators in houses provided at the top of walls?

In a room containing a mixture of hot and cold air, the hot air being less dense rises while cold air sinks. This takes place through convection of air. ... So, in order to maintain convection currents to keep the air fresh and cool in the room, ventilators are provided at top.

How does ventilation work in the lungs?

Ventilation, or breathing, is the movement of air through the conducting passages between the atmosphere and the lungs. The air moves through the passages because of pressure gradients that are produced by contraction of the diaphragm and thoracic muscles.

Can you survive Covid on a ventilator?

But although ventilators save lives, a sobering reality has emerged during the COVID-19 pandemic: many intubated patients do not survive, and recent research suggests the odds worsen the older and sicker the patient.
