This project has been scheduled and executed within February 13th and November 20th, 2015. As can be seen at Table One, it represents the overall tasks of varied portions in the project. The summary of final report is shown as followed. The project has been conducted to propose indoor air quality strategies for assisting the Environmental Protection Bureau of Chiayi City to set up indoor air quality control policy and further bring it in execution. The framed tasks include: 1) generating basic location database 2) investigating indoor air quality of the locations, 3) constructing tactics of location improvement and its follow-up guidance, and 4) conducting management strategies for monitored locations. By reviewing domestic and international technological literature as well as relative resources from governing bureaus, this project devotes to maintaining first-level indoor air quality and promoting the superior policy of Chiayi City.Four illustration meetings were held for propagating to the first group of monitored locations, the second group of monitored locations, hotels, libraries, fitness centers, cram schools and swimming pools…etc. The percentage of attendance reached more than70%. The scores of before-meeting tests in comparison with after-meeting tests averagely grow upright as 2%-3%. In total, 95% of satisfaction was rated by the participants of those meetings.Twenty of them were found abnormal; banks were ranked as the first with abnormality, hospitals the second, hotels the third. The reason of abnormality in the banks was the lack of circulation between inside and outside spaces. For hospitals, it has been abnormal because of the numerous patients. For hotels, it has been abnormal because fragrances were mixed into the air conditioning system.In combination with inspection work, 100 counseling services were implemented to assist the locations to create their maintenance and management proposals. Moreover, we helped the locations carry out the working procedure when dealing with unfavorable air quality and understand the details of regulations. The return rate of questionnaires reaches 98% and the satisfaction reaches 100%. An inter-bureau coordination meeting has been conducted to discuss about issues of indoor air quality. In that meeting, according to some follow-up surveys by means of the meeting records in 2014, we illustrated our working objectives within 2015 and brought out cooperative missions among relevant bureaus. Furthermore, we updated personal information of all participants and investigated valuable shared information relating to evaluation, inspection and relevant regulations for self-management. The coming inter-bureau coordination meeting has been conducted to discuss about issues of indoor air quality.In that meeting, according to the first record of meeting, and 2015 implementation of the outcome.Separately in March, June, August, October in 2015, we commissioned inspection organizations certificated by Environmental Protection Administration of Executive Yuan to examine 5 types of air pollutants to each location. The examination items focused on location control, bacteria and fungus examination in conjunction with direct reading examination equipment to work on comparison of the investigation. There was no abnormality found from the comparison. For the announcement standard examination method section in the first quarter, two of the locations were unqualified as failure on formaldehyde; they were Chiayi branch store of Carrefour and National Chiayi University.Pollutant investigations to 50 Temples were implemented two times; one on weekdays and another on festivals. The average amounts of contaminants detected on weekdays were CO: <0.01 ppm, CO2: 431 ppm, TVOC: 1.28 ppm, PM10: 41 μg/m3, PM2.5: 15 μg/m3; while those on festivals were CO: 1.2 ppm, CO2: 470 ppm, TVOC: 1.67 ppm, PM10: 151 μg/m3, PM2.5: 91 μg/m3.We commissioned examination organizations certificated by the Environmental Protection Administration of Executive Yuan to examine doubly towards 16 locations with abnormality upon direct reading investigation. The result showed that Huang Bin Library of Cultural Affairs Division of Chiayi City was worked out over amount of formaldehyde at 0.15 ppm and failed test for the amount of CO2 at 1,699 ppm.The tasks focused on 30 locations with abnormality by means of direct reading instrumental investigation or with overloading according to standard examination. We invited two professionals to provide real-field guidance service in each location. Regular problems were found as followed: 1) lack of routine cleanness on air-conditioning filters or on cooling standpipes; 2) lack of air injection from outside to the air conditioning system; 3) mildew stain on ceilings; 4) too crowded working place; 5) poor maintenance for the air-conditioning controlling rooms.In application with our techniques, we successfully assisted the library of Chiayi Cultural Affairs Bureau to improve its indoor air quality by outside air injection through fans and continuously monitoring CO2 through an intelligent controller. The effort has reduced the extra amount of CO2 and then has made it fit the standard of indoor air quality.A demonstration meeting has been held to represent excellent samples of indoor air quality improvement. In terms of yearly “real field research on improvement of technique study and its effectiveness,” the demonstration propagated and explained the improvement strategies to colleges, libraries, government divisions, department stores, shopping malls, hospitals, nursery schools, banks, cram schools and fitness centers…etc. There are some routine tasks when working on the project. First, monthly investigation reports have been released and maintained every month. Next, we have kept analyzing pollutants and generating effective strategies to prevent pollution. In addition, professional suggestions from real field guidance were provided to help the locations maintain good indoor air quality. Networking information is updated and maintained to provide Chiayi citizens with awareness of current activities, meetings and various messages about indoor air quality.News about indoor air quality was broadcasted to help citizens understand ways of good indoor air quality maintenance, regulations, and execution results worked out by the Environmental Protection Bureau.This project has carried out routine indoor air quality maintenance and management, pollution prevention and policy trend. There have been some posters, brochures and animations provided to guide citizens on daily indoor air quality maintenance.
