Final answer:
Indoor Air Quality (IAQ) encompasses the various factors of air inside a building and is influenced by chemical and biological pollutants. Adequate ventilation is key to managing IAQ, as it helps to remove pollutants and circulate fresh air. Factors like radon and mold can negatively impact IAQ, leading to health risks such as sick building syndrome.
Step-by-step explanation:
The term that refers to the physical, chemical, and biological characteristics of air in the interior spaces of a building or facility is Indoor Air Quality (IAQ). IAQ is an important health consideration, as most people spend approximately 90 percent of their time indoors.
Physics plays a role in determining the dimensions and structural strength of a room which, in turn, can influence IAQ through factors such as ventilation.
Indoor air pollutants are varied and can include chemical pollutants such as radon, a radioactive gas that increases cancer risk, and biological pollutants like molds, pollen, and pet dander. Inadequate ventilation can contribute to the buildup of these pollutants, leading to what is known as sick building syndrome, where building occupants experience health symptoms linked to time spent inside the building.
Understanding sources of pollution, such as burning fuels, environmental tobacco smoke, and household products, is crucial for maintaining good indoor air.
Improvements in IAQ can be facilitated by ensuring proper ventilation. Air exchange occurs through infiltration, natural ventilation, and mechanical ventilation systems which work to remove indoor air laden with pollutants and replace it with filtered and conditioned outdoor air.
When the air exchange rate is low, pollution can accumulate, so it's vital to consider the rate of air exchange and the presence of ventilation devices in the building's design and maintenance.
