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. Except for Pingtung Veterans General Hospital, a newly added officially announced premise, all of the preceding announced premises have installed dedicated personnel, determined an indoor air quality maintenance and management plan and performed regular analyses and results reporting. In terms of on-the-job training of dedicated personnel, there are 15 premises that haven’t completed the training and each case remains 1~2 years deadline. Furthermore, we proceeded with compiling how dedicated personnel in Pingtung County conduct indoor air quality maintenance and management and cooperated with Planning Section to recommend dedicated personnel to participate in “Environmental Dedicated Personnel and Technicians Selection”. The selection result for indoor air quality management specialty goes to Liugdui Hakka Cultural Park and it is the only one in the country.
This project has inspected 221 public or private premises including 12 and 42 officially announced premises for the first and the second batch respectively and 167 non-announced premises and executed 1,659 times of inspection testing using the direct reading instruments. The first time inspecting rate is 24% that achieves the highest in the past four years. The incidences of instant high value for CO2, HCHO, PM2.5 and PM10 are 6.3%, 28.5%, 3.1% and 5.3% respectively while inspection testing for this year. Compared with incidences of 2021, the incidence of HCHO, PM2.5,and PM10 decreased by 6.1%, 16.1%, and 5.3% respectively and the incidence of CO2 increased by 1.7％. There were more first-inspected premises this year that consisted mostly of elementary schools and small gyms and most small and medium premises have no inlet of outdoor fresh air and personnel lack indoor air quality management cogitation that caused an incidence increase of CO2 instant high value. Some of instant high value of HCHO associated with indirect interference from the electrochemical formaldehyde direct reading instrument due to premises’ necessary cleaning and sanitizing with cleansing alcohol. However, some HCHO instant high values result from decoration or gas cooking. Furthermore, in line with government COVID-19 epidemic policy, most of premises adopt natural ventilation and cause the instant high values of PM2.5, PM10 whenever pollution sources like poor outdoor air quality, mobile sources, nearby construction sites, etc., exist.
As regards the promotion of indoor air quality maintenance and management system, we have comprehensively guided 31 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 has tracked 40 premises that maintenance and management plans already established to confirm document contents, 25 of which did not match current situation and the project team helps them revise their maintenance and management plans to ensure that those premises deal with various IAQ problems properly.
With respect to the inspection analyses of indoor air quality standards, 18 key premises were chosen to complete the analyses, and all premises complied with Indoor Air Quality Standard this year. In addition, on the basis of the statistical analyses of the inspection analyses of indoor air quality standards over the past five years, the main test items that failed to comply with Indoor Air Quality Standard are carbon dioxide and bacteria for shopping malls, and carbon dioxide for medical institutions. However, there have been no premises that exceeded indoor air quality standards over the past two years after the project team comprehensively guided them to improve indoor air quality.
As regards the indoor air quality advocacy, we summarized all common IAQ pollution sources and its improvement strategies for different types of premises in graphic account with propaganda E-cards and E-posters, and promoted them in regulation propaganda held this year. E-cards and E-posters can help 87.5% of premises understand how to improve indoor air quality, and help 91.7% of premises provide information concerned to their supervisors to discuss which IAQ improvement measures should be adopted. This was according to the survey, held by the project team after the propaganda.
As regards the promotion of the self-management mark of indoor air quality (i.e., IAQ self-management mark), this year the project team got support from other competent authorities to budget for application of the mark for offices concerned and we worked to build up the guiding mechanisms of the mark obtainment for private premises to help premises perform IAQ Standard analyses through inter-bureau negotiation meeting so we can keep promoting the mark obtainment of public and private premises and elevate the county’s mark popularization.
As regards the indoor air quality investigation for campuses (junior high school level or below), the project team investigated indoor and outdoor air pollution sources of 20 campuses and executed continuous monitoring of indoor air quality of 6 campuses in order to realize their indoor air quality after implementing “installation of air conditioning units in every primary and secondary school classroom across the island” policy planned by the Executive Yuan. Based on investigation results, the project team proposed “indoor air quality self-management strategy for campuses” including strategy for CO2 improvement and split-type air conditioner maintenance and made the self-management guiding E-posters so that the school can easily realize how to maintain indoor air quality of classrooms.
