dc.description.abstract | The indoor air quality problem arises in the wake of generation evolution, life style of human changed from agricultural oriented society to an industrial and business oriented society, and other changes like industrial structure, consumer behavior and architectural characteristics. Activities of people, the use of equipment and chemical substances, problems of building structure may become the root causes of pollution inside the high-riser.
With an awareness of indoor air quality among Taiwanese people in recent years, government manages to amend relevant policies of national indoor air quality and promotes the implementation of such a regulation. Hence, the law of indoor air quality was approved by the Legislative Yuan on Nov. 08, 2011 and announced execution by the President on Nov. 23 in the same year.
This study uses “Indoor Air Quality Assessment Checklist of Office Building” as a tool to predict the indoor air quality for space used. The result shows 31.03 % of areas are ranked as “not good” or “bad.” A field assessment of space used in high-risers shows 38% of floors, the CO2volume of whichexceeds the standard of indoor air quality. On 44% of floors, the total hydrocarbon volume of which also exceeds standard. On some floors, PM2.5reaches 47.77 µg/m3, while PM10 also accumulates up to 77.91 µg/m3, which all exceed indoor air quality standard. Through health risk analysis, the hazard for “respiratory system” within high-riser amounts to 72.73%, which is so much higher than that of “cardiovascular system (7.27%)” and “eye (3.64).”
Under the modes of no further changes of A/C system and personnel operation in existing high-risers, 3 improvement plans are to be implemented, including “improvement of A/C circulation system”, “improvement of welding area”, and “improvement of IAQ checklist.” The outcome of improvement shows the volume of gaseous pollutants and particulate pollutants can be reduced, which also reduces the health risk of personnel.
