Problem Statement CONCLUSION FUTURE WORK 45

2 According to International Code of Practice, ICOP 2010, IAQ is closely related with the heating, ventilation and air-conditioning HVAC system that is used in the building. This means that some of the pollutants that can levels that can be found inside a building can be related to the HVAC system used in the building. A HVAC system is a mechanical system may turn faulty or inadequate. In a research paper by Karina and Maria 2010, it has been stated that to ensure the adequate dilution of contaminants generated in the building, ventilation is necessary. In another research by Syazwan et al., 2009, also indicates a relationship of IAQ and ventilation which is an increase in ventilation will reduce the prevalence of sick building syndrome which is caused by poor IAQ. In order to keep the environmental quality at the desirable level, maintenance of the HVAC system is need according to Sulaiman. et al., 2013. Thus, in this research, the indoor air contaminants status on air conditioning system of a building will be determined and assessed. The parameters of the IAQ which is indoor air temperature, the percentages of relative humidity RH, the air velocity, level of Carbon Dioxide CO 2 , and Particulate Matter PM 2.5 will be measured for a specific time. The level will be compared with the standard level set by ICOP IAQ 2010.

1.2 Problem Statement

There is now ample studies on IAQ and its negative effects Sulaiman and Mohamed 2011, Norhidayah et al., 2013, Yau et al., 2012, Syazwan et el., 2009, Marzuki et al., 2010, Karina and Maria 2010, Sunyoung et al., 2013, Ade et al., 2012, Yang Li 2012, Che-Ani et al., 2012, Rogerio Duarte and Ingride B.C. 2013. However, there are not much research on indoor air quality factor which is indoor air contaminants that is related to the air-conditioning system which is used in a building. As a developing country, the awareness towards the negative effects of poor indoor air quality is low Mohammad A. Hussein, 2012. Thus, this indicates the reason why there were less studies on the indoor air contaminants on the air-conditioning systems. 3 According to ASHRAE 2009, indoor environment health includes those factors of human health and diseases that are affected by the aspects in the indoor environment. As we know, buildings nowadays mostly use air-conditioning system to provide comfort to the occupants especially in Malaysia which is a country with a climate categorized as equatorial, being hot and humid throughout the year. Past studies indicates that IAQ is related with the Heating Ventilation and Air Conditioning system HVAC used in a building Karina and Maria 2010, Syazwan et al., 2009, Sulaiman et al., 2013, ICOP 2010. Thus in Malaysia, we need to study the indoor air quality status on the air-conditioning systems used in the building to ensure that the air produced by the air conditioning system is adequate and safe to the occupants. In Universiti Teknologi Malaysia Melaka UTeM, it is known that the Main Library that is located at the Main Campus never been assessed of its indoor air contaminants status. Note that it has been several years since it is built. Although the quality of air produced by an adequate air conditioning system is always acceptable, there are some factors which will affect the quality of air produced through years of time. According to Sulaiman et al., 2013, it has been concluded that the buildings environment quality will be affected by poor maintenance and it will result to bad productivity and health of the facility management. Thus, it is better to study the status of indoor air contaminants on air conditioning system at UTeMs Main Library so that the status will be known and further actions can be taken if theres any problems indicated.
