Schedules of plan regarding indoor air quality (IAQ) have met the requirements regulated by Environmental Protection Bureau of Taichung. Lists of unqualified public sites via examination and measurements have been included. Statistical results indicated that there were 82 unqualified public sites via examination of CO2. Notably, four parameters (CO2, HCHO, TVOC and CO) of IAQ were all examined sequentially at 29 public sites. Among the unqualified public sites examined employing the standard method announced by Taiwan EPA, they were higher up to 10 unqualified public sites for formaldehyde (HCHO).
There were 110 public sites of a total of 2174 points examined for CO2. Among them, CO2 concentrations for 34 public sites of 168 points exceeded standard (1000 ppm). At kindergartens, the sites where their CO2 concentrations exceeded standard were at the most. Next to kindergartens, exhibition sites and hospitals were the second and third many. Their CO2 concentration ranged 363-1943 ppm. Total Fungi Concentration (TFC) in 10 kindergartens has been examined and the I/O ratios (indoor TFC concentration/outdoor TFC concentration) were also analyzed and investigated. The examination for indoor air pollutants in ten public sites indicated that, concentration of HCHO of one public site exceeded standard. After improving and re-examining, it met the standard eventually. Parts of measurements for the other public sites were close to the corresponding standard. Results of CO2 measurements implied that, devices for ventilation could not properly adjust the gas exchange rate due to residents frequently come and go from public sites. This will also result in the higher concentrations of CO2. Results for parts of public sites revealed that, concentrations of Total Bacterial Concentrations (TBC) were close to standard, meaning that this could result from residents frequently come and go from public sites.
In order to improve IAQ of public sites in Taichung, eight forums (25 public sites contained) with scholars and experts on site has been proceeded by the present team. Track, investigation and re-measurements will be continually conducted for the target (unqualified) public sites. Regulation, three public hearings and 500 copies of flyers concerning IAQ will be completed. By means of announcing the strategies and common drawback improvement concerning IAQ, professional knowledge for management of IAQ about public sites could be promoted. Furthermore, the effectiveness of propagation and instruction for IAQ could be enhanced.
