懸浮微粒為都市空氣品質之污染指標，削減都市中懸浮微粒的集中現象多藉由都市風場帶離，而都市風道則受到街廓量體配置而受阻。本研究之目的在探討建築物之量體造形，對周邊地區懸浮微粒分佈之影響。 本研究選擇某校園街廓量體為實驗對象，以實測與模擬方式，對懸浮微粒做實際量測，並將其結果製作基礎資料套入FLOVENT5.1模擬軟體，電腦模擬分析出一棟建築物若以不同之造形設計，其對於懸浮微粒分佈之影響，並進行改善檢討，以供設計檢討或都市設計審議之參考。 結果顯示，各項模擬之造形改變計畫皆有助於改善校園內之污染值，其中：1、一樓懸空通風改善懸浮微粒PM10減量平均可達67.5%，平均風速增加了0.04m/s，局部改善地面附近水平範圍約達10公尺內之濃度。2、量體集中改善計畫：懸浮微粒PM10減量達16.7%，3、量體部份開口改善計畫：懸浮微粒PM10減量達17.2%。

PM10 have become air pollution index of urban air quality. It is also a dangerous pollutant for human health. PM10 in the urban areas would be mostly removed by air draft in the urban wind field. The wind field is subjected to urban block types, the building form etc. This study would judge how the building form affects the particle distribution. This study is based on observation and simulation. Urban block types in a school campus for an object wewe chosen in Taipei. Its distribution was measured and put into the database for the simulation of PM10 in different urban blocks types. Flovent5.1 would be applied for the comparison with three kinds of different types. The results demonstrate as following: First floor air draft plan reduces the PM10 concentration 67.5%, adds the wind speed 0.04m/s and affects surrounding environment up to 10 meters by distance. Building structure concentrated plan reduces the PM10 concentration 16.7%. Bridge connected buildings structure plan reduces the PM10 concentration 17.2%.
