Abstract
This work focuses on indoor air quality evaluation of commercial buildings in Kuantan. Some buildings have been selected to monitor indoor air quality. The research has been carried out only in Kuantan, which focused on hotels and government buildings. Some sample measurements were taken which include air temperature, relative humidity, and air movement, carbon monoxide (CO), carbon dioxide (CO2), ozone (O3), respirable particulate matter (PM 10), formaldehyde and total volatile organic compound (TVOC). In addition, questionnaires were conducted on a number of workers in each building to determine the level of health and illness caused by air in the building where they work. Hence, this study has analyzed the link between the questioner results and the results of indoor air measurements that were carried out. From surveys, it appears there are four buildings that have low air flow, four buildings have a lot of dust and five buildings have a high temperature. In contrast, four buildings have a good indoor air quality.
Highlights
Indoor air quality (IAQ) is a term which refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of building occupants [1]
If the carbon monoxide (CO) measurements are out of acceptable range, there might be some effect to building occupants
Formaldehyde measurement of different buildings and its corresponding Industry Code of Practice (ICOP) standards limit. From this monitoring of indoor air quality, it is found that a number of buildings have poor indoor air quality, not follow ICOP 2010
Summary
Indoor air quality (IAQ) is a term which refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of building occupants [1]. Determination of IAQ involves the collection of air samples, monitoring human exposure to pollutants, collection of samples on building surfaces, and computer modeling of air flow inside buildings. Human exposure to air pollutants can have negative effects on the well-being of occupants [6]. Many countries national organizations and worldwide influences committees for instance the World Health Organization (WHO) has stipulated standard and guidelines are implemented with the general consensus of limiting exposure of humans to certain breathing air contaminants
