Abstract

IAQ studies are neccessary in order to determine the health and thermal comfort levels in building. However, in UiTM, there is no scientific data on the indoor air contents available especially for the building in the Faculty of Applied Science. Therefore, this project was conducted to provide scientific data of the air contents and ventilation for some selected classrooms based on real scientific measurement. The aims for this study were to measure the contents of indoor gasses (CO and CO₂), indoor air temperature and relative air humidity, to determine whether or not all of the parameters measured are within the acceptable values by comparing with the standards, to obtain the average pattern indoor gasses emission over 24-hr period and to study the effect of the number of occupants to the air contents inside the classrooms. The measurements were carried out 24 hours per day by dividing the analysis into different cases. By using SPSS, normality of the data were analysed and non parametric ANOVA was performed and the data were interpreted according to the objectives. It was found that the average concentrations of CO and relative humidity for eight hours exposure were within the recommended value. However, the average concentrations of CO₂ and air temperature did not comply with the standard guideline. CO and CO₂ have similar emission pattern in which they were found to be higher during the normal lecture hours. It was also found that the number of occupants and the CO and CO₂ emission do not fit the assumption of a linear relationship. Based on the findings, some recommendation are made for the improvement of the indoor air quality especially in those classrooms in order to keep the concentration of CO₂ as well as the air temperature within the standard in accordance to both ASHRAE and DOSH guideline.
