What Application Requires Fresh Air?
The average adult male’s lungs can hold a maximum of 6 litres of air, according to the American Lung Association. This includes air from a normal breath, plus extra air you can force in, additional air you force out after a regular exhalation, and any air left in the lungs after all that. The association estimates that you consume 7,500 litres of air per day.
The air that is inhaled is about 20 percent oxygen, and the air that is exhaled is about 15 percent oxygen, so about 5 percent of the volume of air is consumed in each breath and converted to carbon dioxide. Therefore, a human being uses about 375 litres of pure oxygen per day.
It shows that wherever humans are in an enclosed space the oxygen will be depleted and the CO2 levels will increase.
The introduction of fresh air is the essential element to provide a supply of oxygen that we need.
The building regulations and Australian Standards cover the need of fresh air in buildings and varies according to the use, intensity of occupation, space, and volume.
In practice it is an appropriate vision to incorporate fresh air into the design of every structure, not only where it is mandated.
