Comparative study of indoor air contaminants in different stages of new building occupancy: work environment assessment

Indoor Air Quality (IAQ) is a part of Building Environment. Nowadays, the construction of new building took place over the world. Upon new building occupancy, a lot of indoors material was used without IAQ concern. This study has been conducted in a new constructed building of the National Institute of Occupational Safety and Health (NIOSH) Malaysia. The goal of the study is to monitor on the level of IAQ parameters including chemical and physical parameters within four consequent stages which are before furniture install, after furniture install and during one and three month occupancy. The indoor parameters have been measured consist of nine parameters including of Carbon Dioxide (CO2), Carbon Monoxide (CO), Total Volatile Organic Compounds (TVOC), Formaldehyde, Respirable Particulates (PM10), Ozone, Relative Humidity (RH), Temperature and Air Movement. The interaction between Malaysian and international standard was referred and utilized in collecting the data and analyzing of the findings. There was a significant correlation between the high values of RH, Formaldehyde and PM10 where (r 0.324, p <0.05), (r 0.344, p <0.05) and (r 0.319, p
