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.
1.3 Objectives of The Study
Main Objective:
• To determine the indoor air contaminants status on air conditioning system in
Main Library of UTeM.

Specific Objectives:
1. To measure the parameters of IAQ which is indoor air temperature, the percentages of relative humidity RH, the air velocity, level of Carbon
Monoxide CO, level of Carbon Dioxide CO

in Main Library of UTeM.
2. To determine the source of the factors that influence the IAC and IAP in Main Library of UTeM.
3. To compare the data collected with International Code Of Practice ICOP
standard to analyze the status of IAC and IAQ of air conditioning system in Main Library of UTeM.
4. To associate the relationship between IAC and air conditioning system.
1.4 Work Scope of The Study
In this research, a cohort study was carried out at UTeM’s Main Library from September 2014 to October 2014. A total of seven sections of the Main Library will
be assessed by the researcher on environmental aspects of IAC in AC system. The focus will be mainly on collecting data related to IAC and IAQ which is indoor air
temperature, RH, air velocity, CO

presented in the air in seven section of the UTeMs Main Library to be related with the air conditioning
system used. Lastly, the study will include the comparing of data collected from the field measurement with the level agreed with the International Code of Practice ICOP
Indoor Air Quality 2010 standard to evaluate the status of IAC and IAQ of air conditioning system in Main Library of UTeM.

2.1 Introduction
In the literature review, the author have found a good representative literature discussing the effects of poor indoor air quality IAQ and indoor air contaminants
IAC with their relationship with the air conditioning system used in a building. However, there was less study in detail about the relationship of the materials used for
the construction of the building or air conditioning system with the level of IAQ. The author is grateful to some authors Sulaiman and Mohamed 2011, Yang 2012,
ASHRAE 2009, Yau et al., 2012, Wang and Zhang 2010, ICOP 2010 who identified some of the factors that have affected the levels of IAQ in a building, although their
discussions outline funding as a major factor in this progress as opposed to good IAQ, effective ventilations and adequate filtrations. By studying the relevant literature, it
will help the author understand more fully how other factors play a big role in indoor air quality IAQ in buildings.
