摘要

目標：公寓大廈地下停車場多為密閉型空間，導致污染物無法自然排出，造成空氣品質不良。因此，本研究以公寓大廈地下停車場為調查對象，探討空氣品質之現況及問題點，並且解析其空氣品質影響因素。方法：本研究針對台灣南部地區16棟（39個地下樓層）公寓大廈地下停車場進行污染物(CO、CO2、NO(下標 X)、PM10)量測及住戶問卷調查，並針對可能影響因素進行現況調查後，再利用SPSS統計軟體進行相關性檢定。結果：氣狀污染物濃度越往下樓層越高，尖峰時段每往下一層樓CO濃度提升2.1 ppm、CO2濃度提升21.0 ppm、NO(下標 X)濃度提升59.9 ppb，其中CO尖峰最大平均濃度26.1 ppm；NO(下標 X)尖峰最大平均濃度為743 ppb。有關滿意度調查顯示，住戶對地下停車場的綜合不滿意度為27%，其中以通風狀況不滿意度最高(37%)。結論：在公寓大廈地下室停車場污染物中以NO(下標 X)（平均濃度超過250 ppb為14棟(87.5%)）最為嚴重。另外，案例抽排風系統之效能不佳（平均效能下降至原設計值49%），造成地下停車場污染物無法有效排出。

Objectives: Most underground parking lots for condominium buildings are closed spaces. The pollutants cannot be discharged naturally, resulting in poor air quality. This study investigated the air quality and pollution problems affecting the underground parking lots of condominium buildings, and analyzed the factors affecting air quality. Methods: Measurements of the pollutants CO, CO2, NO(subscript X), and PM10 were taken from the underground parking lots of 16 condominium buildings (39 floors) in southern Taiwan, a household questionnaire was given to users of these underground parking lots, and the status of probable affecting factors was investigated. A statistical analysis of the data was conducted with SPSS. Results: There was a higher concentration of gaseous pollutants at the lower floors. During peak traffic time, for every floor that was lower, the CO concentration increased by 2.1 ppm, the CO2 concentration increased by 21.0 ppm, and the NO(subscript X) concentration increased by 59.9 ppb. The maximal average peak CO concentration was 26.1 ppm; and that of NO(subscript X) was 743 ppb. A satisfaction survey showed that the overall dissatisfaction rate of residents toward the underground parking lot was 27%, with the ventilation earning the highest dissatisfaction rate (37%). Conclusions: Among the pollutants present in the underground parking lots of condominium buildings, NO(subscript X) (average concentration exceeding 250 ppb in 14 tested buildings (87.5%)) was the most severe. In addition, it was found that inferior performance of the air ventilation system in the buildings (average efficiency dropped to 49% of the original design value) led to the failure of effective discharging of underground parking lot pollutants.
