5. Recommended Further Studies
In light of the findings from this Study, the consultants recommended a more detailed study on the economic evaluation of the impacts of IAQ which may take the form of a government initiated cost-benefit analysis of improvement in IAQ. There are obviously costs in upgrading 'hardware' set up (such as ventilation) and 'software' management system in enforcement, monitoring, licensing and complaints investigation related to IAQ. However, the consultants in its preliminary economic analysis has illustrated that such cost will be more than offset by the gain made in the reduction of medical cost and regaining the loss in productivity due to 'sickness' at work.
The consultants also recommended further research into indoor air quality problems in educational institutions which carry out a variety of activities from laboratory work to physical exercise, and medical institutions where special control of gases, chemicals and micro-organisms is necessary. Institutions with susceptible groups including schools, hospitals and homes where the young, the aged and the sick are present, should also be considered as cases for further study.
