There are 12 and 42 officially announced premises that shall meet Indoor Air Quality Act for the first and the second batch respectively in Pingtung County during the implementation period. The announced premises currently have all completed the establishment of dedicated personnel, formulation of maintenance management documents, and regular inspection and reporting operations in accordance with regulations, achieving a regulatory compliance rate of 100%. Regarding the on-the-job training of dedicated personnel, there are still 12 premises that need to complete retraining within one or two year timeframe. The subsequent project team will closely monitor whether the announced premises complete the on-the-job training courses as scheduled.
This project has inspected 162 public or private premises including 12 and 42 officially announced premises for the first and the second batch respectively and 108 non-announced premises and executed 1,201 times of inspection testing using the direct reading instruments. The first time inspecting rate is 28% which achieves the highest in the past four years, The incidences of instant high value for CO2, HCHO, PM2.5 and PM10 are 4.7%, 13.7%, 0.9% and 0.4% respectively while inspection testing for this year. Compared with incidences of 2022, the incidence of CO2, HCHO, PM2.5, and PM10 decreased by 1.6%, 14.8%, 2.2%, and 4.9% respectively. The occurrence rates of pollutants' high values in inspections are the lowest in the past three years. The occurrence of high values in HCHO inspections is related to necessary alcohol disinfection interfering with the electrochemical formaldehyde direct reading instrument, while others are mostly due to on-site renovation activities. The high values in PM2.5 and PM10 inspections are mainly due to ongoing renovation work in some premises or the use of water mist disinfection machines indoors. The use of humidifiers can interfere with the light scattering PM sensor and result in high inspection values.
As regards the promotion of indoor air quality maintenance and management system, we have comprehensively guided 33 premises to determine their indoor air quality maintenance and management plans and help non-officially announced premises add plan contents into their daily engineering check procedure for processing indoor air quality maintenance and management works in advance. In addition, the project team tracked premises that had established maintenance management documents in previous years and assisted 24 premises with content discrepancies to correct their documents, ensuring that operators can properly manage indoor air quality.
In terms of standard value testing, a total of 21 key premises completed standard value testing operations this year. For instance, at Gaoshu Kindergarten, the bacteria concentration exceeded the standard value (1,000 CFU/m3), reaching 2,147 CFU/m3. The project team assisted the premises in understanding the source of pollution and recommended an increase in indoor cleaning and disinfection frequency. Subsequent retesting showed bacteria concentrations of 1,408 and 827 CFU/m3, both below the standard value of 1,500 CFU/m3. Moreover, based on the statistical results of standard value testing over the past five years, the main items that did not comply with the standards in various types of officially announced premises were carbon dioxide and bacteria. The types of premises with exceedances were mainly shopping malls and medical institutions. After the project team assisted in improvement, there have been no exceedances in the past two years.
In terms of indoor air quality promotion, a total of 61 participants attended regulatory promotion seminars this year. Additionally, in order to enhance public awareness of indoor air quality, the target audience has been expanded to include the general public and schoolchildren. This year, a promotional event with booths was also organized, employing interactive and fun activities such as maze games and quizzes to enhance participants' awareness of indoor air quality.
In the promotion of the Indoor Air Quality Self-Management Mark, the project team secured support and budget allocation from competent bureaus to facilitate the acquisition of the mark for their jurisdictional office premises through inter-bureau meetings. A collaborative mechanism was jointly established to guide premises within the jurisdiction in completing the test analysis of indoor air quality standards. This initiative aims to sustainably promote the acquisition of the Indoor Air Quality Self-Management Mark within the jurisdiction and enhance the prevalence of the mark in this county. According to the statistics provided by the Ministry of Environment as of the end of November, 2023, the number of marks issued in this county temporarily ranks first among all country except the six Special Municipalities (the current number of marks obtained within the jurisdiction is a total of 85).
