Quick Answer
VENTILATION IS CRUCIAL IN IGLOO CONSTRUCTION AS IT PREVENTS INSULATION FROM GETTING DAMP, REDUCES CARBON DIOXIDE BUILDUP AND IMPROVES AIR QUALITY, ALLOWING OCCUPANTS TO BREATH EASILY.
Importance of Ventilation in Igloo Construction
Ventilation plays a vital role in igloo construction as it prevents moisture buildup and reduces the risk of hypothermia. Igloos are designed to be well-insulated, which means that they can quickly become humid and produce carbon dioxide from occupants’ breath and body heat. Without proper ventilation, the air inside the igloo can become stale and hazardous to occupants.
Techniques for Improving Ventilation in Igloos
In traditional Inuit igloo construction, ventilation is achieved through a small opening at the top of the structure, called the “vent hole.” This hole allows cold air to enter and warm air to escape, helping to regulate the temperature inside the igloo. To improve ventilation, builders typically create a small opening or a series of small openings around the perimeter of the igloo, about 1-2 feet from the ground. This helps to draw in cold air and prevent the buildup of carbon dioxide.
Ventilation Considerations in Igloo Design
When designing an igloo, builders must consider the wind direction and take into account the location of the vent hole to ensure proper ventilation. A vent hole that faces directly into the wind can help to draw in cold air and improve ventilation. Builders can also use a technique called “breathing holes” to create a series of small openings around the perimeter of the igloo, which helps to regulate the temperature and prevent moisture buildup.
