Abstract: Indoor Air Quality (IAQ) can affect the human health, comfort as well as their overall productivity in work. The impact of Indoor Air Quality on a child can affect their health more adversely than an adult as they are more vulnerable to viruses. Therefore, it is important to make sure that the IAQ in kindergartens are maintained at an acceptable level so that it will reduce the risk of transmission of all the air borne diseases among the children. This research will investigate the aspect of IAQ of kindergartens in Singapore with the following main objectives (i) to determine and compare the air quality between two different environments of kindergartens –air conditioned and naturally ventilated; and (ii) propose and explore possible measures that can be made to reduce and prevent the child potential exposure to biological, chemical and physical agents in the kindergarten. Case studies of the two different types of ventilated kindergartens were being carried out. Results are gathered from the experiments and questionnaire survey conducted on the occupants – teaching staff in the kindergartens. The phenomenon of increasing temperature reduces the rate of relative humidity has been justified in the case studies that are being carried out. Naturally ventilated center produced a better indoor air quality as compared to fully air conditioned center. As natural ventilated center appears to be more ideal and thermally comfortable with lower level of carbon dioxide, total volatile organic compound and bacteria, yeast and mould counts. It also has a higher rate of relative humidity whereby less skin irritation and dryness will be experienced. Provision of fresh air is crucial in reducing the contaminants in the enclosed premises. Furthermore, greenery located near the center also plays a part in the provision of fresh air. Fully air conditioned center could further improved its existing condition by providing adequate supply of fresh air to dilute the contaminants.
