Indoor Air Quality of SWD Offices

In 2003, Environmental Protection Department launched the Indoor Air Quality (IAQ) Certification Scheme to promote and commend good IAQ management practice. Offices or public places served by mechanical ventilation and air conditioning (MVAC) systems (excluding window-type air-conditioners or split-type air-conditioners) are eligible to join the IAQ Certification Scheme.

Eligible premises of the Department have joined the IAQ Certification Scheme and had their IAQ assessed regularly. 111 premises have attained the "Excellent" or "Good" IAQ Class.
