| Summary: | 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<0.05) with extension of phases of new building occupancy respectively. This study
established significant different on Formaldehyde and Particulate Matter (PM10)
concentration level as go along with the building occupancy. These finding indicated
that furniture and fittings, indoor materials and human population has a potential
sources of indoor air contaminants. It is recommended that the management should be
aware to their indoor air status to protect the occupant from the risk of unwanted
exposure especially during the early stage of building occupancy. Finally this research
has fully supported the Malaysian need to formulate of future guideline on IAQ
commissioning and maintenance of new building occupancy. |
