The explanatory meeting on the autonomous management and improvement technology of indoor air quality (IAQ) was held on September 30, 2010. In order to enhance advertisement, 500 advertising brochures and 100 posters were prepared. Another explanatory meeting on autonomous IAQ management was held on January 25, 2011. In this project, 42 public locations were selected for CO2 detection as IAQ screening. The results showed that 8 public locations in Category 1 exceeded Taiwan EPA suggested IAQ threshold, and all public locations in Category 2 met the suggested IAQ threshold. Based on IAQ detection of the screened public locations, 5 public locations were chosen for the detailed IAQ measurement by the EPA standard methods. The results showed that Deguang Kindergarten exceeded the suggested IAQ threshold on O3 and PM10, and National Tainan Senior Marine Fishery Vocational School exceeded the suggested IAQ threshold on bacteria, fungi and O3. In order to initiate Tainan City’s five-star label ranking system for autonomous IAQ management, a short course for IAQ specialists was held in Kun Shan University. The project team has tutored 20 IAQ specialists at public locations to complete their autonomous IAQ management proposals, and assigned IAQ experts to on-site review and modify 10 autonomous IAQ management proposals. The project team also established 10 IAQ emergency and response proposals of public locations to reduce health impact by IAQ incidents. There are 106 public locations involved in Tainan City’s five-star label ranking system for autonomous IAQ management. Label ranking showed 82 public locations in one-star or two-star, 18 public locations in three-star, 5 public locations in four-star, and 1 public locations in five-star levels. The five-star and the four-star medals were awarded to the organizations by Mayer Lai of Tainan City in the awarding ceremony on July 27, 2011. The thee-star, the two-star, and the one-star certificate were sent to the organizations during the explanatory meeting on August 4, 2011. The reported IAQ pollution cases at public locations were collected in these two years. Based on statistical data, 45% of IAQ pollution cases occurred at schools and educational locations. According to the classification of measured IAQ items, IAQ pollution cases were often caused by CO2 (34%).
