Indoor Air Quality
Indoor Air Quality in a Nutshell
Why is indoor air considered the determining factor of human exposure to airborne contaminants? (ASHRAE’s definition)
Because, people spend the majority of their time indoors, and that indoor air contains contaminants originating from both indoor and outdoor sources. Many of these contaminants affect health, comfort, and productivity. It is crucial to incorporate good IAQ practices in a building’s HVAC system design, construction, and operation. The benefits of improved IAQ are societal and individual well-being. Good practices of IAQ for buildings include Source Control (contaminant emissions, from occupant activities, prevention through filtration, environmental impacts including moisture and humidity control), Ventilation, and Air Cleaning.

Environment with poor IAQ is commonly termed as Sick Building Syndrome and Indoor Air Polluted.
A prolonged poor IAQ condition can trigger all kinds of illnesses and allergies.
Five (5) key IAQ indicators are CO2, PM2.5, TVOC, RH and Temperature. In the commercial environment, an Air Handler Unit, AHU which is located mostly on the roof of buildings serves to regulate these key indicators.
However, in the household or small-medium size premises having an AHU is not possible. Separate and compact devices such as Air Purifier, Dehumidifier, In-built UV Lamps and Ionizer, Ventilators, and Air Conditioner are commonly used. However, none of these individual devices can regulate the 5 IAQ indicators like an AHU in isolation. Or, devices bought from different vendors may not work coherently.
