Indoor air quality (IAQ) in a building is a very important element to ensure the health and comfort level of the building occupants. This is because work productivity may be interrupted due to the polluted environmental condition and bad indoor air quality. Both factors may lead to bad health and physical condition and consequently to bad work performance. The study presents the understanding and knowledge of how indoor air quality (IAQ) affects psychological performance and health impact to the occupants in office buildings in Malaysia. The finding shows that in the current situation, most respondents are not satisfied with their office’s current indoor air quality. This condition is believed to be one of the contributing factors affecting occupants’ work productivity and stress level. Nevertheless, this research managed to provide better understanding and valuable information on how indoor air quality affects psychological performance and health condition of the occupants in office buildings. Recommendations are made to improve the indoor air quality performance in order to provide a comfortable working environment for the occupant.
