Exposure to indoor air pollution is becoming serious public health problem in a wide variety of non-industrial setting such as residences, offices, schools, hospital and vehicles. This study intended to investigate the level of airborne microbe in indoor environment at three different phases of building commissioning for a new constructed building in Bandar Baru Bangi, Selangor, Malaysia. The airborne microbes’ concentrations were determined by using a single stage impact or (Biosampler) as per requirement of National Institute of Occupational Safety and Health (NIOSH) method, NIOSH Manual Analytical Method NMAM 0800 were used in this study. The total concentration of airborne bacteria and fungi were average 641 and 338 CFU/m3 in the first phase, 133 and 117 CFU/m3 in the second phase, and 389 and 52 CFU/m3 in the third phase. These findings indicate that although a new constructed building should be having a significant background level of airborne microbe (total bacteria and total fungi). The building owner should be aware to their building maintenance status to protect the occupant from the safety and health problem (risk). The study also can be the basics baseline study of new constructed ventilated building
