營建工程所建設的建築物及公共構造物等,應以維護民眾生命的健康為首要,但在現今的建築環境中,卻潛藏著危及居民健康的污染源,要改善這些污染源,應該從提倡使用健康的建築材料著手才是根本之道。本研究主要在實際檢測各種不同室內空氣的品質,並運用攜帶型檢測儀器檢測室內環境中有益之負離子及可能危害的污染源,例如甲醛、揮發性有機化合物、二氧化碳等,結果顯示室內空氣中有些上述危害物質均超出政府建議上限值,甲醛最高達2.20ppm;揮發性有機化合物最高達134ppm;二氧化碳最高達1945ppm。另外也檢測使用含負離子的綠建材使用於建築室內,並探討正負離子的釋放數量,使用此健康綠建材可提升室內負離子濃度約46%。本研究成果可作為綠色建築評估及審查之參考。
Buildings and infrastructures made by construction engineering should protect people''s health. Pollution generally hides everywhere around us in our buildings. To prevent these pollutant sources from making damage, the most effective way is to advocate using of healthy building materials. This study focused on the actual detection of a variety of indoor air quality, and tested the useful negative ions and harmful polluted sources by using portable devices. The harmful sources include formaldehyde, volatile organic compounds, and carbon dioxide. The results show that some quantities of hazardous substances of the indoor air exceed the suggested limits by Government. The most serious values of formaldehyde, volatile organic compounds and carbon dioxide are 2.2ppm, 134ppm and 1945ppm respectively. Besides, a green building material containing negative ions was used in the building interior. The quantities of positive and negative ions were detected. Use healthy green building materials can increase the indoor anion concentration for about 46%. These research results can be used for references of green building assessment and investigation.
