Indoor Air Quality Work environment , business or at home , all often require people to spend a majority of their time indoors . As an outcome , inhabitant ’ s ( of indoor area ) health and comfort are largely reliant on establishing and sustaining good levels of Indoor Air Quality ( IAQ ). Quality of the air inhabitant breathe is connected to many factors ; for example humans beings get rid of 4kg ( approx .) of skin every year and a lot of this shredded skin transport through indoor air and could either transfer to other inhabitant ’ s lungs or it would fluster as household dust . This can be increased further through other variables , such as carpets , cleaning chemicals , pets , paints , air fresheners and much more , all which can create more indoor pollution and reduces the air quality .
In hot countries , such as the UAE , the concern of preventing heat to enter the building and saving the air conditioning efficiency in indoor spaces has resulted in poor indoor air quality and has also caused the collection of pollution related factors to dust , germs , bacteria , chemicals used for cleaning and others . Sickness symptoms like breathing problems , headache , and skin irritations is a result of poor air quality that contributes in an uncomfortable environment which gives a negative effect on the productivity and health of occupants . Elements that results in a poor indoor air quality is related to the design of the space , indoor finishing , level of activity in the building and the air supply to the building through HVAC system ( Chiang 2008:140 ).
The indoor air quality is a major contributor to Building Related Illness ( BRI ) and Sick Building Syndrome ( SBS ) affecting occupants . Thus , what should be monitored , neutralized or kept under control ? Gaseous pollutants : Total Volatile Organic Compounds ( VOCs ), Formaldehyde , Carbon Monoxide , Oxygen , Pentane and others . Particulate pollutants : These come from different type of sources and can come in Fine particles ( 2.5 micrometer in diameter or even smaller ) which can come from power plants , vehicle tailpipes , industrial processes and woodstoves , or can be coarse particles ( anything between the 2.5 and 10 micrometer in diameter ), which is a result of grinding and crushing operations , agricultural operations or road dust ( EPA 2013 ; Hedge 2009 ).
Many types of mitigation strategies have been identified , developed and implemented over the years when it comes to solving IAQ problems . Mitigation of indoor air quality issues sometimes may require involving staff or facility management which represents areas such as ( 1 ) Facility Op-
