Abstract

Human spend most of their time indoor. So, the quality of indoor environment should be assessed and improved ensure a comfortable and safe indoor environment. However, in UTHM Pagoh there do the building occupants face a major facility problem, which is the noise, coming from the air-conditioning system. In this study, the objectives are to identity the causes and the effects of air-conditioning system noise in UTHM Pagoh and to propose the solution to control the problem. There are three main method used to verify the objectives. The first one is by questionnaire distribution to all building occupants. It is found that their physiology, communication and performance are affected by the noise produced. Secondly, physical data were measured using sound level test. It is found that the Total Average Noise Level in all laboratories exceeded the standard by WHO and ASHRAE, which is 55dBA. Lastly, the interview sessions were conducted to determine the causes and the effects of the noise. Through these interviews, it is found that the causes of the noise are location of air-conditioning blower and return air duct from the room that are too close to the laboratories. The solution listed is design stage control. The solutions proposed is installation of noise insulation using acoustic material and relocation of the return air duct from the room to a higher position.
