The main purpose of this case is to assist the Nantou County Government to promote the improvement of indoor air quality. During the planning period, it will cooperate with the Nantou County Environmental Protection Bureau to carry out indoor air quality management inspections of public and private (announcement) places (the inspection content includes the installation of specialized personnel and maintenance management plans. Circumstances of writing and reference, indoor air quality inspection and measurement records, and the announcement of inspection and measurement results. What the industry should do). In this plan, it is recommended to perform inspections on the places where inspections are carried out. Priority will be given to inspections of the first and second batch of announcement places and the assessment places of this year; the second priority is selected for the inspection of the indoor air quality plan in 108 years, the carbon dioxide concentration detection The result exceeds the regulatory standard value of 1,000 ppm and the indoor air carbon dioxide concentration with the risk of exceeding the standard is higher than 800 ppm; the third priority object is selected based on the type of announced controlled places but does not reach the announced listing level; finally, more people are added And more sensitive sites that have not been inspected in the past. According to the inspection results, those who are at risk will be given priority to conduct carbon dioxide inspections and preliminary improvement counseling suggestions. 106 indoor air quality inspections and carbon dioxide inspections have been carried out for 114 times, including 4 government agencies and 14 evaluation sites. Offices, 7 libraries, 7 medical institutions, 12 educational institutions, 41 kindergartens, 10 social welfare institutions, 1 sports and fitness center, 1 underground parking lot, and 9 other types of places. Among the 106 inspected places, 79.3% of the places did not exceed the carbon dioxide concentration in the indoor air, and only 20.7% of the places (22 places) exceeded the carbon dioxide regulatory value of 1,000 ppm, of which 8 places exceeded the standard, 10 spaces and 35 points had high concentrations At 1,500 ppm. The 22 carbon dioxide inspection sites were 13 kindergartens, 2 medical institutions, 3 libraries, 1 audio-visual and singing place, 1 shopping mall, 1 social welfare institution and 1 educational institution. The carbon dioxide concentration exceeded the regulation by 1,000 ppm. The standard. Most of the factors that exceed the standard of carbon dioxide are insufficient ventilation and excessive number of users, causing the accumulation of indoor air pollutants to exceed the standard. Among them, kindergartens and libraries have repeatedly exceeded the standard in inspections over the years. They have been actively counseling and improving, Nantou County Government Cultural Bureau Book The museum has decreased year by year, reaching 695ppm in 109, and the improvement effect was also 41.1%, showing the effectiveness of publicity and guidance.
TVOC inspects 75 places in its jurisdiction, of which 5 places exceed the standard, and the proportion of the total places exceeds the standard. The 5 places are 3 medical institutions, and 1 tourist factory and 1 shopping mall. 4 indoor air quality regular inspections and 3 TVOC project testing and analysis have been completed. The unqualified places are 1 medical institution and 1 kindergarten. The above-mentioned unqualified medical institutions will continue to plan the follow-up expert counseling, and provide improvement suggestions for the situation where the carbon dioxide inspection exceeds the standard and the regular inspection of the bacteria exceeds the standard. Another expert counseling session was for social welfare facilities. The incense burning behavior in the Buddhist hall of the place caused the PM2.5 concentration in nursing stations and the elderly activity space to be higher than the legal standard value. After the counseling was improved, the PM2.5 concentration in the venue A sharp drop of about 60%. In addition, the project completed 3 press releases and 910 promotional materials purchases, 1 type of indoor air quality education and implementation results of the publicity lazy package, and completed 4 indoor air courses for campuses and public and private places. Quality promotion enables the public and school children to establish a correct concept of indoor air quality maintenance and bring the concept into the family.
