This study aims to help the Nantou County Government promote indoor air quality improvement projects. During the research period, the research team cooperated with the Environmental Protection Bureau of Nantou County to implement patrol inspections of indoor air quality management in public and private (declared) venues. The inspection content included establishment of responsible personnel, writing and future reference of maintenance management plans, indoor air quality test and measurement records, declaration of test and measurement results, and other tasks the operators should complete.
This study started on April 29. As of November 20, the research team completed air quality patrols at 90 venues and 95 businesses, as well as CO2 patrol operations at 872 spots of 338 spaces in 90 venues. Among the 90 venues undergoing indoor air quality patrols, 10% exceeded required thresholds. The patrol results revealed that venues such as libraries, medical institutions, preschools, and fitness centers easily induce concerns for poor indoor air quality because of dense gathering of individuals and inadequate ventilation. Appropriate opening of windows and control of indoor personnel density can avoid excessive concentration of indoor CO2. Among the venues with excessive CO2 concentrations, fitness centers are the focal point of the yearly review; therefore, the research team will endeavor to help fitness centers achieve favorable indoor air quality. In total volatile organic compound inspection in 54 venues, 13 venues exhibited values exceeding the threshold. Such venues were mainly underground parking lots, hospitals, fitness centers, and preschools. During the patrols, the research team used handheld direct-reading PM2.5 sensors to inspect 63 venues. The readings revealed that most of the venues had a PM2.5 concentration between 0 and 23 μg/m3, conforming to legal requirements. However, in 2 underground parking lots, PM10 concentration exceeded the legal threshold.
In Nantou County, 12 second-batch declared venues should complete the second regular inspection this year and upload their declaration information after the inspection. So far, 10 venues have completed the procedures. The research team will assist the remaining two venues to complete the required procedures.
According to the contract requirements, the research team must complete indoor air quality regular inspection at 5 venues. The list for patrol was selected from venues exceeding the legal requirements, venues declared by the Environmental Protection Bureau as venues classified for monitoring and inspection, batch-based declared venues and relevant venues, or venues designated for patrols by the Environmental Protection Bureau. Regular inspections of the 5 venues (2 underground parking lots, 2 preschools, and 1 elementary school) were completed by November 14. The regular inspection results indicated that all the 5 venues conformed to required standards. Among venues that were detected with excessive pollutant concentrations this year, 2 venues were selected for which experts were invited to provide guidance and improvement suggestions to help them improve their indoor air quality. The procedures were completed by October 31. In mid-August and early October, an education and training session for instructing the tasks the venues classified for monitoring and inspection should complete and a session of promotional explanation were held, respectively. Interdepartmental meeting was planned to be held on November 21. Two press releases were completed and another press release will be completed by early December. Procurement of 500 demonstration items was completed and passes inspection on October 30. As of November 20, the research team completed 4 promotional sessions of indoor air quality in the campus and public and private venues to impart correct indoor air quality maintenance concepts to the public and students, who can then share the concept with their families or friends. Consequently, the promotional goal of this study can be achieved.
