Indoor Air Quality Certification Scheme for Hong Kong Buildings

Abstract

The Hong Kong SAR Government has taken initiatives to improve indoor air quality (IAQ) in various facilities. The most recent is the development of an IAQ Certification Scheme for Offices and Public Places. Following criticism of an earlier draft some of the IAQ criteria were relaxed, yet remain comparatively tight specifications for air-conditioned buildings. Launched as a voluntary scheme it could become a significant driving force to improve building performance. However, pilot studies have shown the complexity and cost of undertaking an assessment will be a significant deterrent. Here, the key elements of the scheme are outlined, the suitability of the IAQ criteria discussed, and the difficulties in meeting the prescribed measurement protocols identified. Suggestions are made for improvements to the scheme that would encourage take-up by building owners.
