6. Conclusion and Way Forward
The Study concluded that indoor air pollution in Hong Kong is very similar to that of other developed countries. The air quality in about one-third of the office buildings was perceived as unsatisfactory by the occupants and has violated WHO or relevant overseas standards.
The approach adopted so far in controlling IAQ in Hong Kong is through establishing basic air quality standards and ventilation requirements. There are already statutory provisions to require buildings, workplaces and specified public places such as restaurants and cinemas to comply with basic ventilation and air quality standards but these responsibilities are split among a number of government departments. A more comprehensive mechanism to strengthen the control over IAQ may be warranted subject to a review of the situation by the Management Group in three years' time. For the interim, a comprehensive CoP giving a set of IAQ objectives and good practices on the management and enhancement of IAQ has been developed for use by the related professionals and building management. The Study recommended that the provisions of certain existing regulations should be further utilised to address the issue of indoor air pollution by making reference to the CoP.
Improving IAQ has been shown to bring economic benefits through higher worker productivity and lower medical costs. The assurance from the Government to actively maintain acceptable IAQ standards in Hong Kong buildings is an important element for international community to decide to work and live in Hong Kong. IAQ also plays a part in Hong Kong's competitiveness as an international business centre in the region. With a concerted effort and a sound institutionalised scheme of control, the IAQ of our buildings can be made more acceptable and provide a healthy environment for people to live and work in. Government buildings should take the lead for voluntary control and that should be good news for business, public and government alike.
