本計畫蒐集彙整辦公大樓密閉空間空氣污染物相關資訊，並實地測量植物之淨化能力；於台北市某辦公大樓密閉空間(中央空調辦公室及獨立窗型冷氣機辦公室)，不同地點(辦公人員區域及影印機區域)等四處進行二氧化碳、甲醛及細懸浮微粒量取樣及數據分析；於夏季及冬季各試驗一次。結果顯示室內二氧化碳濃度於夏季時中央空調辦公室之測值明顯較獨立窗型冷氣機辦公室高；甲醛濃度以中央空調辦公室高於獨立窗型冷氣機辦公室，夏季高於冬季，影印間略高於辦公人員座位區，未擺放植物者略高於擺放植物者；細懸浮微粒濃度整體而言冬季之測值較夏季高，而中央空調辦公室之測值又高於獨立窗型冷氣機辦公室。 應用常見23種室內植物，包括6種臺灣原生植物，實地置於辦公大樓空間，結果顯示多種植物於置放一星期後仍可維持光合作用能力。袖珍椰子、合果芋、白鶴芋‘綠巨人’及黛粉葉於各試驗場所均表現良好，且照顧容易適合擺放。臺灣原生植物中尤其以蜘蛛抱蛋之光合作用能力表現最佳；而其他如山蘇、竹柏、鵝掌藤、黃金榕和羅漢松亦有較高之淨光合作用速率，但須考量置放於光線明亮處，則可提供更多室內擺設選擇。 根據參考文獻及試驗結果，建立辦公大樓中不同位置植栽選擇與配置資料庫與示範；結合近幾年計畫執行成果，製作撰寫中、英文「室內植物淨化空氣Q＆A」宣導手冊。並舉辦三場室內植物淨化空氣說明會，利用簡報及實際植物佈置方式，以加強一般民眾對此議題之認識與應用。

The aim of the project was to study the air pollutants in airtight office building, and the ability of several plant species to reduce air pollutants. Carbon dioxide (CO2), formaldehyde, particulate matter (PM) concentrations were monitored in window type air conditioned and central air conditioning offices, and at different locations (cubicle area and printing room). Each office/location were monitored for seasonal effect (summer and winter). Results showed that indoor CO2 concentration was higher in the central air conditioning office than in the window type air conditioned office during summer. Indoor formaldehyde concentration was higher in the central air conditioning office than in the window type air conditioned office, higher during summer than winter, higher in the printing room than cubicle area, and higher when without plant decoration than those with plant decorated. Over all PM concentration was higher during winter than summer, with central air conditioning office higher than the window type air conditioned office. Twenty-three indoor plant species, including six Taiwan-native species, were placed in the offices. Results showed that many plant species were able to maintain photosynthesis 7 d after placing in the offices. Parlour palm (Chamaedorea elegans), arrowhead plant (Syngonium podophyllum), peace lily (Spathiphyllum ‘Sensation’), and dumb cane (Dieffenbachia ‘Camilla’) had good performance throughout the experiment and were easy to grow. Off all tested Taiwan-native plant species, cast-iron plant (Aspidistra elaitor) had the highest photosynthetic rate. Other plant species, like bird’s nest fern (Asplenium nidus), Podocarpus macrophyllus, Schefflera arboricola, Ficus microcarpa ‘Golden Leaves’, and Nageia nagi also had higher photosynthetic rate, but should be placed at brighter sites. According to collected references and experimental results, we established data base of recommended indoor plantation and decoration examples. A booklet has been edited as House Plants Purify Indoor Air – Q&A. Three conferences on indoor plants improving air quality were held for promoting the knowledge and application of the topic.
