Rainwater collected undergoing simple filtering to become water without coming in contact with the human body is the most common way adopted by new buildings. The status quo, however, presents a great discrepancy and is unsuitability inasmuch use is concerned, in that the taxonomy which the current criterion relies upon is too simplistic. For this reason, this study aims at Taipei's elementary schools by exploring the rationality and feasibility of the use of rainwater storage for flushing toilets in dedicated building types. Based upon existing campuses, the present work attempts to propose rainwater storage and flushing system suitable for elementary school. This study lays emphasis on practical applications. Starting with Taipei's rainfall using 15 weather stations, it discusses the influence of variations in Taipei's topography on rainfall. By characteristics of rainfall distribution, seasonal change, probability of precipitation, Taipei is divided into four areas and seven sub-areas. Rainfall of locations is corrected based upon the distance between campus and measuring stations. The result shows that according to the influence of Taipei's topography on precipitation, it is indeed improper to base rainfall storage design on a single rainfall station alone. After surveying types and areas available for collecting rainwater on the campuses, it is found that campuses collect rainwater by prioritizing roofs, followed by the hard tracks of playgrounds. In respect to rainwater collection, the result indicates that campus roof rainwater collection is concentrated in approximately 20% of the area, and that the highest collection is concentrated in September due to precipitation conditions. According to the campuses' means from weather stations in terms of roof areas alone, differences in extreme values of rainfall are close to 20 times. Extreme values at one single weather station are nearly 7 times at maximum. If collection of playgrounds is included, there is a difference of 7 times in weather stations' means. The result shows that factors that affect the difference of times at weather stations in the same areas include collection areas, in addition to the campus position. Differences between campuses at one single weather station are affected by the factor of whether monthly rainfall is even. According to an analysis on water use on campuses, the population is the factor that has the biggest influence. The study has formulated a relation between population and rainfall supply needed. The supply-demand relation indicates that by raising the collection of playgrounds, the number of campuses with a supply-demand replacement ratio at 100% all year round can increase from 3 to 8. The study clustered the campuses, set up reference time-points against supply-demand replacement ratios, and compared with newly built campuses using the lowest replacement ratios. The result indicates that using roof rainfall collection design, the lowest point of clustering control is Shipai Weather Station's supply-demand ratio of 13% in January. If rainfall collection of playground tracks is included, the lowest point is Tianmu Weather Station at 25%. These two areas are in the low-rainfall A-1 area. Data that show differences in rainfall constitute an influence. The study attempted a rational storage for seven months of actual use, but provided instead a 6-month comparison mechanism for campuses with an overly low replacement ratio. The result shows that for a number of campuses, there was little difference in storage use rates in six months or seven months. But when set values for capacity were increased (100 M3), the initial cost could be reduced to shorten the period of return on investment (ROI), and the overall efficiency could be enhanced. Comparing the difference between actual conditions and design can change a rational storage design. Moreover, evaluation can be made according to the ROI of initial equipment costs. Finally, the study discusses the current establishment problems and makes suggestions on facilities in order to propose a rainwater storage system to serve as a reference for existing and new campuses in single construction or in overall establishment.目錄…………………………………………………………………………………..Ⅰ表目錄………………………………………………………………………………..Ⅳ 圖目錄………………………………………………………………………………..Ⅵ 第一章 緒論…………………………………………………………….…………..1 1-1 研究動機………………………………………………………………………..1 1-2 研究目的………………………………………………………………………..3 1-3 研究範圍與限制………………………………………………………………..4 1-3-1 研究範圍限定………………………………………………….…………..…4 1-3-2 研究假設……………………………………………………………………...5 1-4 研究內容與流程………………………………………………………………..6 1-4-1 研究內容與方法……………………………………………………………...6 1-4-2 研究流程……………………………………………………………………...9 第二章 文獻回顧與分析...………………………………………………………11 2-1 文獻回顧理念…………………………………………………………..…..11 2-2 雨水利用現況…………………………………………………………..…..11 2-2-1 雨水利用定義………………………………………………………….11 2-2-2 國內外雨水利用現況…………………………………………………11 2-3 文獻分析……………………………………………………………..………13 2-3-1 研究基礎性文獻與利用內容………………………………………….13 2-3-2 文獻探討與分析……………………………………………………….17 第三章 雨量供給與需求…………………………………………………………..22 3-1 地區降雨探討……………………………………………………………….22 3-1-1 測候站位置探討……………………………………………………….22 3-1-2 測候站降雨特性說明………………………………………………….27 3-1-3 台北市測候站雨量分區……………………………………………….34 3-1-4 測候站分區檢討與設站建議………………………………………….34 3-2 台北市國小對應測候站探………………………………………………..…...38 3-2-1 台北市國小數量與位……………………………………………….…38 3-2-2 國小與測候站對應探討……………………………………………….39 3-3 校園集雨量……………………………………………………………….……43 3-3-1 校園降雨量…………………………………………………………….43 3-3-2 集雨面積利用條件序………………………………………………….43 3-3-3 屋頂集雨量…………………………………………………………….44 3-3-4 校園跑道集雨量………...………………………………………..…..45 3-4 台北市國小需雨量…………………………………………………………………48 3-4-1 國小需水因子分析…….……...…………………………………………….48 3-4-2 台北市國小雨水之需求……………………………………………….52 第四章 校園雨量供需替代………………………………………………………..57 4-1 校園屋頂面積供雨替代率探討…………………………………………….57 4-1-1 A-1區屋頂集雨替代率……………………………………………..59 4-1-2 B-1a區屋頂集雨替代率…………………………………………….61 4-1-3 B-1b區屋頂集雨替代率…………………………………………….63 4-1-4 B-2 區屋頂集雨替代率....………………………………………….64 4-1-4 D 區屋頂集雨替代率………………………………………………66 4-2 校園跑道面積替代率……………………………………………………….66 第五章 雨水利用模式建立………………………………………………………..68 5-1 分區集群標準模式探討…………………………………………………….68 5-2 分區集群歸屬機制………………………………………………………….71 5-3 集群控制月份……………………………………………………………….71 5-4 貯留量探討………………………………………………………………….73 5-5 水費價格調整……………………………………………………………….76 第六章 案例估算實證…………………………………………..…………………78 6-1 新設國小校園設計案例…………………………………………………….79 6-2 現況國小校園模擬雨水利用設計……………………………………….…83 第七章 結論與建議………………………………………………………………..86 7-1 結論………………………………………………………………………….86 7-1-1 台北市地域性降雨分析………………………..…………………...86 7-1-2 台北市國小集雨量………………..………………………………...87 7-1-3 台北市國小需雨量……………………………..…………………...88 7-1-4 台北市國小雨水供需替代特性…………………………………….89 7-1-5 台北市國小合理化貯量設計……………………………………….89 7-1-6 校園案例模擬與設計探討………………………………………….91 7-2 建議………………………………………………………………………….92 7-2-1 台北市國小校園雨水利用之應用………………………………….92 7-2-2 後續研究……………………………………………………………93 參考文獻……………………………………………………………………………..95 附錄…………………………………………………………………………………..98 附錄3-1 氣象站月均降雨基礎資料……………………………………………98 附錄3-2 學校對應測候站分區平面座標及海拔資料….…………………….100 附錄3-3 台北市國小需水迴歸………………………….…………………….102 附錄3-4 台北市國小建築屋頂面積集雨量表………………………………..106 附錄3-5 台北市國小需水迴歸………………………………………….…….108 附錄3-6 校園面積比對基礎人口數…………………………………………..112 附錄4-1 台北市校園各月降雨替代率表………………………………….….115 附錄4-2 台北市校園各月屋頂集雨加操場集雨替代率表…………………..118 附錄5-1 分區校園屋頂集雨對應集群利用率表……………………………..121 附錄5-2 分區校園屋頂集雨+操場跑道集雨對應集群利用率表……………1262718877 bytesapplication/pdfen-US國小校園替代率雨水貯留氣象站群集分析elementary schoolsreplacement ratiosrainwater storageweather stationscluster analyzethesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/50435/1/ntu-95-D90521019-1.pdf
