||In response to the trend of environmental awareness and sustainable world, the Ministry of Education since 2006 to promote "sustainable campus local transformation plan" subsidies, in order to target specific sustainable practices on campus, there are a number of national primary schools to apply for and obtain the plan of grants, and transformation project is a very important part of the campus base water retention performance improvement.|
And because the campus in the city, in addition to the base to accommodate cultural and educational facilities and activities, on the property is also part of the public facilities, and both education, sports, leisure, disaster prevention, asylum and other multiple functions, so the purpose of this study is to explore the current system of practice on the campus of the base water retention facility design there are two on the subject, one of the current formula for calculating the "rain delay (t)" should local conditions? The second was the use of a sample analysis of the current school campus base water retention facility design trends and blind spots, and finally by the preceding two paragraphs discuss the subject, and make recommendations based on the establishment of security, "all kinds of soil water in the base of existing formulas for improving the existing calculation formula facility design principle ", in order to improve the industry's water conservation facilities in the campus-based facilities" inertia design "instead of focusing on the future of the base so that the water retention design practices more in line with the characteristics of the physical environment of the base.
After analysis to explore research topics, the following conclusions:
(A) Due to the current base water retention is calculated based on "legal space ratio * 0.5" water retention as a base reference value for each case, was not due to natural conditions in different regions and adjusted to the level of the recommendations should be adopted in terms of practice, "according to local conditions "is calculated, and the inner and outer base load capacity considerations drainage system.
(B) the existing norms formula rain delay (t) if the value is adjusted in accordance with the assumptions of the proportion of the average daily rainfall in each region after the spreadsheet, the rest of the original design conditions under the same premise, the base value of the majority of water retention design remains unchanged , changes in the value of a small number of changes in its proportions and adjust the ratio is also different, outside the scope of this study was to investigate a lot of room for discussion should be otherwise.
(C) In the analysis of each study sample current base water retention facility design trends found that the current design approach tendencies are "inertia design" and did not thoroughly consider the "environmental characteristics", it is in terms of cost control and better design techniques None program.
(D) by the various types of water conservation facilities cost base to explore the effectiveness of the analysis process, difficult to find existing norms set formula, there are many parts oversimplified, except no different regional climatic conditions into consideration, nor will be temporarily stored in together with consideration of surface water bodies, in terms of practical level more appropriate to the aforementioned environmental factors into consideration.
(E) The current base water retention specification formula not be building material differences into account (such as differences in "high-pressure concrete brick" and "concrete permeable brick" is), and can be included in the calculation of the labor law and building materials within a limited range, the lack of breadth also a disguised restriction reduced the building designer's creativity.
