Abstract: This proposed research project is recorded as the first time in such hot and humid climate in Singapore; therefore it becomes significant in its potential to provide real-time field data of UVGI system and its impact on cooling coils, which are operated in fully wet conditions all year around. This research project provides a better and deeper understanding of the effectiveness of UVGI systems in controlling microbial growth on the surfaces of the coil/drain pans and keeping them clean, which has both IAQ and energy benefits. And due to the time constraints, all the data collection and analysis of this report is mainly focus on the AHU from the building of YSTCM. There are two type of measurements were carried through the experimental data collection which are spot measurement and continuous measurement for microbial growth and energy efficiency respectively. There are two week pre measurement data and four to five weeks data are available for this research project in microbial and energy analysis to do the comparisons on changes of the bacteria and fungus count before and after UVGI system operation and also to observe the trend of energy data distribution for key indicators of energy saving effect, like pressure drop and water heat transfer rate.
