INTRODUCTION
1.1 RESEARCH BACKGROUND
The US Environmental Protection Agency (EPA) and the US Consumer Product (1995) (as cited in Preethi, 2005) sated that people spend approximately 90 percents of their time being indoors. Therefore, for many, due to more exposure of indoor air pollution than outdoor air pollution the risk to health may be greater.
The building occupants may be exposed to the variety of contaminants whether in the form of gases and particles derived from office machines, construction activities, cleaning products, carpets and furnishing, perfumes, cigarette smoke, water-damaged building materials, microbial growth (fungal, mold and bacterial), insects, and outdoor pollutants because the indoor environment are highly complex (CDC, 2013).
Indoor environmental quality is most simply describes as the conditions inside the building. It is not only includes air quality but also includes the access to daylight and views, pleasant acoustic conditions, and occupant control over lighting and thermal comfort. Besides that, it is also includes the space functional aspect such as whether the layout provides easy access …show more content…
