Concerns toward Indoor Air Quality (IAQ) in office building tend to risen since most people spend their working hours
indoors compare to outdoors. Exposure to indoor pollutants is a considerable problem. Therefore, there is a need to monitor IAQ in
order to deter further air quality deterioration in the workplace. The objective of this study is to determine the level of IAQ parameter
in selected academic office. The important IAQ parameters considered in this study were the air temperature, air velocity, relative
humidity, CO2, CO, TVOC, formaldehyde and respirable particulate matter. Measurements were conducted using commercial IAQ
instruments. From the study it was found that the levels of TVOC and respirable particulate matter were higher than the recommended
limit during photocopying activities. The formaldehyde, CO2 and CO level were observed to be acceptable for an office based on
Industry code of practice on indoor air quality (ICOP-IAQ 2010). Results shows that the temperature and air velocity are located at
acceptable value of 22-25 ºC and 0.1-0.1 m/s. Findings also show high relative humidity that exceeded the requirement level of 40%-
70%. Detail investigations are needed in order to provide certain guidance in improvement of IAQ conditions in office environment.
