水资源的保护措施英语作文范文(精选5篇)【篇一】水资源的保护措施英语作文 Who is willing to drink the polluted water It can cause us to be ill and even to die. We can"t wait for a moment to protect our water sources. The water we use comes from oceans, lakes, rivers or streams. But many of these water sources are getting seriously polluted. Towns and cities are pouring dust into the water. Many people are throwing all kinds of dirty things into the water. Factories are pouring waste material into the water. Therefore, water sources have become so badly polluted that some of the water is unfit to drink or to use. Now it is high time that we should do something to protect our water environment from being polluted.带翻译:被污染的水会使人生病甚至死亡,有谁愿意喝这样的水呢我们要保护水源是刻不容缓的。

文献信息:文献标题:Issues in Sustainable Architecture and Possible Solutions (可持续建筑中的问题及可能的解决方案)国外作者:Fatima Ghani文献出处:《International Journal of Civil & Environmental Engineering》,2012,12(1),p21-24字数统计:英文1985单词,11317字符;中文3460汉字外文文献:Issues in Sustainable Architecture and Possible Solutions Abstract—The growing concern with environmental and ecological conditions have led to the discussion/search for ‘energy conscious’, ‘Eco friendly’, ‘energy efficient’ building designs. For the better growth of the future, keeping in view the environment related issues, the first objective of the designer is sustainable development i.e. environmentally compatible building designs. Sustainable architecture also referred as green architecture is a design that uses natural building materials e.g. earth, wood, stone etc (not involving pollution in its treatment) that are energy efficient and that make little or no impact on the nature of a site and its resources. This paper discusses issues related to Sustainable/environmental architecture. It also considers possible solutions related to these issues.Index Terms—Sustainable, Green, Architecture, Building, Design. Efficiency.I. INTRODUCTIONThe words "Green", "Ecological" and "Sustainable" are terms used by environmentalists to indicate modes of practice. From global economics to household features these practices minimize our impact on the environment and generate a healthy place of living. In a deeper sense the words involve as to what can be done to heal andregenerate the earth's ability to bear life.A.Principles of Environmentally Oriented DesignIn Architecture there are many ways a building may be "green" and respond to the growing environmental problems of our planet. Sustainable architecture can be practiced still maintaining efficiency, beauty, layouts and cost effectiveness. There are five basic areas of an environmentally oriented design. They are Healthy Interior Environment, Energy Efficiency, Ecological Building Materials, Building Form and Good Design.• Healthy Interior Environment: It has to be well insured that building materials and systems used do not emit toxic unhealthy gases and substances in the built spaces. Further extra cars and measures are to be taken to provide maximum levels of fresh air and adequate ventilation to the interior environment.• Energy Efficiency: It has to be well ensured that the building's use of energy is minimized. The various HV AC systems and methods of construction etc. should be so designed that energy consumption is minimal.• Ecological Building Materials: As far as possible the use of building materials should be from renewable sources having relatively safe sources of production.• Building Form: The building form should respond to the site, region, climate and the materials available thereby generating a harmony between the inhabitants and the surroundings.• Good Design: Structure & Material and Aesthetics are the basic parameters of defining design. They should be so integrated that the final outcome is a well built, convenient and a beautiful living space.These principles of environmentally oriented design comprise yet another meaningful and environmental building approach called Green or Sustainable design. Architects should use their creativity and perception to correlate these principles to generate locally appropriate strategies, materials and methods keeping in mind that every region should employ different green strategies.B. DefinitionSustainability means 'to hold' up or 'to support from below'. It refers to the abilityof a society, ecosystem or any such ongoing system, to continue functioning into the indefinite future (without being forced into decline through exhaustion of key resources).Sustainable architecture involves a combination of values: aesthetic, environmental, social, political and moral. It's about one's perception and technical knowledge to engage in a central aspect of the practice i.e. to design and build in harmony with the environment. It is the duty of an architect to think rationally about a combination of issues like sustainability, durability, longevity, appropriate materials and sense of place.The present environmental conditions have led to the discussion/search for ‘energy conscious’, ‘Eco friendly’,‘energy efficient’ building designs. For the better growth of the future, keeping in view the environment related issues, the first objective of the designer is a sustainable development i.e. environmentally compatible. This paper discusses issues related to Sustainable/environmental architecture. The main focus of the paper is on sustainable architecture - its need, solutions and impact on the future.II. NEEDS AND ISSUESThe ecological crisis today is very serious and till date much of the debate still focuses on the symptoms rather than the causes. As a result there is an urgent need to emphasize and workout the best possible approach towards environmental protection thereby minimizing further degradation.Architecture presents a unique challenge in the field of sustainability. Construction projects typically consume large amounts of materials, produce tons of waste, and often involve weighing the preservation of buildings that have historical significance against the desire for the development of newer, more modern designs. Sustainable development is one such measure, which presents an approach that can largely contribute to environmental protection. A striking balance between Environmental protection and Sustainable development is a difficult and delicate task.Sustainable design is the thoughtful integration of architecture with electrical,mechanical, and structural engineering. In addition to concern for the traditional aesthetics of massing, proportion, scale, texture, shadow, and light, the facility design team needs to be concerned with long term costs: environmental, economic, and human as shown in Figure 1.III. CONCEPT AND RELEV ANCE OF SUSTAINABLE ARCHITECTURE In the present day scenario the idea and concept of Sustainable Architecture/Development is relevant in the light of the following two aspects:a) Ecological and Environmental crisisb) Imminent disasters and their managementSome of the major causes, which greatly contribute to these two aspects, can be listed as:• Rapid Urbanization and Industrialization:The consequences of this can further lead to Population explosion, Geological deposits of sewage and garbage, Unsustainable patterns of living & development, Environmental degradation (pollution of air, water, soil etc, food web disruption). Thus sustainable urban development is crucial to improve the lives of urban populations and the remainder of the planet. Both people and ecosystems impacted upon by their activities.• Natural Calamities:Natural calamities like volcanic eruptions, earthquakes, flood, famine etc. which are being further aggravated by mankind add to the list of other ill effects like atomicexplosion, green house effect, ozone depletion etc. Sustainable design attempts to have an understanding of the natural processes as well as the environmental impact of the design. Making natural cycles and processes visible, bring the designed environment back to life.• Depletion of Non-renewable sources:Rapid depletion of non-renewable sources is leading to serious issues related to energy & water conservation etc. Thus the rational use of natural resources and appropriate management of the building stock can contribute to saving scarce resources, reducing energy consumption and improving environmental quality.IV. SOLUTIONSA. Sustainable ConstructionSustainable construction is defined as "the creation and responsible management of a healthy built environment based on resource efficient and ecological principles". Sustainable designed buildings aim to lessen their impact on our environment through energy and resource efficiency."Sustainable building" may be defined as building practices, which strive for integral quality (including economic, social and environmental performance) in a very broad way. Thus, the rational use of natural resources and appropriate management of the building stock will contribute to saving scarce resources, reducing energy consumption (energy conservation), and improving environmental quality.Sustainable building involves considering the entire life cycle of buildings, taking environmental quality, functional quality and future values into account environmental initiatives of the construction sector and the demands of users are key factors in the market. Governments will be able to give a considerable impulse to sustainable buildings by encouraging these developments. Further the various energy related issues during the different phases in the construction of buildings can be understood with respect to the chart shown in Figure2.B. Environmentally Friendly HousesFollowing the five basic principles of environmentally oriented design can lead to the construction of what can be called as Environmentally Friendly House. An environmentally friendly house is designed and built to be in tune with its occupants, nature, environment and ecosystem. It is designed and built according to the region it is located in, keeping in mind the climate, material, availability and building practices. The basic areas of design need to be considered at this stage can be listed as: • Orientation• Reduce Energy Gain or Loss• Lighting• Responsible Landscaping• Waste Management• External VentilationC. Green BuildingA green building places a high priority on health, environmental and resource conservation performance over its life cycle. These new priorities expand and complement the classical building design concerns: economy, utility, durability and delight. Green design emphasize a number of new environmental, resource and occupant health concerns:• Reduce human exposure to noxious materials.• Conserve non-renewable energy and scarce materials.• Minimize life cycle ecological impact of energy and materials used.• Use renewable energy and materials that are sustainable harvested.• Protect and restore local air, water, soil, flora & fauna• Support pedestrian, bicycles, mass transit and other alternatives to fossil-fueled vehicles.Most green buildings are high quality buildings they last longer, cost less to operate and maintain and provide greater occupant satisfaction than standard development.D. Green Roofs & Porous PavementsAs already discussed the rapid urbanization and industrialization is resulting in extensive deforestation as a result the green areas are being covered with pavements and concrete. The rainwater that naturally seeps through land covered with vegetation and trees now just runoff, thereby leading to a major environmental imbalance in terms of groundwater. This problem can be solved to a great extent with the help of the construction of Green Roofs and Porous Pavements.Green roofs & porous pavements present a unique method of ground water conservation. Vegetation to hold water on rooftops, and pavement that lets it percolate in the ground are some of the latest ways that can save water tables. Visually what might come across may be a roof sprouted with plants and a parking lot that drains water like a sieve-probably the latest in groundwater conservation.E. Building MaterialsTons of materials including timber go into building construction. There are three principal approaches to improve the material efficiency of building construction: • Reducing the amount of material used in construction.• Using recycled materials that otherwise would have been waste.• Reducing waste generation in the construction process.Further as far as possible sustainable harvested building materials and finishes should be used with low toxicity in manufacturing and installation.V. CONCLUSIONSSustainability often is defined as meeting the needs of the present without compromising the ability of future generations to meet their own needs. A growing number of people are committed to reaching this goal by modifying patterns of development and consumption to reduce demand on natural resource supplies and help preserve environmental quality. Achieving greater sustainability in the field of construction is particularly important, because building construction consumes more energy and resources than any other economic activity. Not only does a home represent the largest financial investment a family is likely to make, but it also represents the most resource- and energy-intensive possession most people will ever own. Making homes more sustainable, then, has a tremendous potential to contribute to the ability of future generations to meet their own needs. Sustainable housing design is a multifaceted concept, embracing:• Affordability• Marketability• Appropriate design• Resource efficiency• Energy efficiency• Durability• Comfort• HealthAs a developed society we should not undermine our resource base, the assimilative capacity of our surroundings or the biotic stocks on which our future depends. As a sustainable society our efforts should consist of a long-term and integrated approach to developing and achieving a healthy community. We should realize that the problems associated with sustainable development are global as a result the issues need worldwide attention. If we work together we can bring change faster.中文译文:可持续建筑中的问题及可能的解决方案摘要——越来越多地关注环境和生态条件已经引起了人们对“节能意识”、“友好生态”、“高效节能”的建筑设计的讨论和探索。
绿色建筑给排水设计的节水措施摘要:在建筑给排水系统设计中节水措施的应用有利于建筑整体水资源利用效率的优化,同时还能降低水分渗漏给建筑结构造成的损害,提升建筑的环保价值与建筑运行耐久性。
给排水系统中应用节水技术措施与节水理念,可以实现建筑环保价值的提升,是建筑行业向着环保、绿色方向发展的重要一步。
关键词:绿色建筑;给排水设计;节水措施1我国现阶段建筑给排水系统设计中水资源浪费问题的深入分析1.1建筑给排水压力设计不科学由在我国当前的建筑发展形势来看,高层建筑数量不断增多,对给排水设计中压力的计算要求增大,因为建筑给排水系统中水压必须确保建筑最高层能够得到充足的水资源供给,而水压又不能对给排水管道的安全运行造成影响,所以对系统水压的设计必须保证科学。
但是在当前很多建筑设计人员看来,水压只是细小计算的一部分,因此对其不够重视,导致在很多建筑项目中给排水系统的水压都过大,造成很多建筑楼层的用户的水流太快而出现水资源浪费的问题。
同时过大的水压也会对管道结构形成冲击,导致管道结构的破损以及渗漏水问题的出现。
1.2卫生器具选择不当造成节水效果差当前针对节水需要已经研发与生产了很多种类的节水卫生器具,但部分建筑给排水系统构建中并没有科学使用节水卫生器具,导致建筑给排水运行中在卫生器具环节出现了水资源无谓消耗与浪费,这不利于我国水资源保护事业的发展。
部分建筑单位在进行建筑内部卫生器具采购中也忽视了节水效果,较为注重卫生器具的价格,这就加剧了给排水系统中器具浪费水的问题。
1.3建筑给排水中没有设置科学的水资源回收系统由于在大部分建筑给排水运行中所排出的废水是一些能够进行净化处理并进行循环利用的较为清洁的水,对这些水资源进行回收利用,可以提升建筑中水资源的利用效率。
因此,在进行建筑给排水设计时应该做好水资源回收系统的设计工作,对一些自然降水、未使用化学品的清洁工作产生的废水等进行物理沉淀以及消毒等技术处理,而后再将其投入到对水质要求不高的用水区域中去。

This paper introduces the Green Building program and proposes a water conservation index with quantitative methodology and case study. This evaluation index involves standardized scientific quantification and can be used in the pre-design stage to obtain the expected result. The measure of evaluation index is also based on the essential researchin Taiwan and is a practical and applicable approach.Keywords: Green Building; Evaluation system; Water conservation; Building equipment1. IntroductionThe environment was an issue of deep global concern throughout the latter half of the 20th century. Fresh water shortages and pollution are becoming one of the most critical global problems. Many organizations and conferences concerning water resource policy and issues have reached the consensus that water shortages may cause war in the 21st century[1],if not a better solution .Actually, Taiwan is already experiencing significant discord over water supply. Building new dams is no longer an acceptable solution to the current water shortage problems, because of the consequent environmental problems. Previous studies have concludedthat water savings are necessary not only for water conservation but also for reducing energy consumption [2,3].Taiwan is located in the Asian monsoon area and has an abundant supply of rainwater. Annual precipitation averages around 2500mm. However, water shortages have recently beena critical problem during the dry season. The crucial, central issue is the uneven distribution of torrential rain, steep hillsides, and short rivers. Furthermore, the heavy demand for domestic water use in municipal areas, and the difficulties in building new reservoirs are also critical factors. Government departments are endeavoring to spread publicly the concept of water-conservation. While industry and commerce have made excellent progress in water conservation, progress among the public has been extremely slow.Due to this global trend, the Architecture and Building Research Institute (ABRI), Ministry of Interior in Taiwan, proposed the “Green Building” concept and built the evaluation system. In order to save water resources through building equipment design, this system prioritizes water conservation as one of its seven categories. This paper focuses on the water conservation measures for Green Building in Taiwan and a quantitative procedure for proving water-saving efficiency. The purpose of this work is not only aimed at saving water resources, but also at reducing the environmentalimpact on the earth.2. Water conservation indexThe water conservation index is the ratio of the actual quantity of water consumed in a building to the average water-consumption in general. The index is also called, “the water saving rate”. Evaluations of the water-consumption quantity include the evaluation to the water-saving efficiency within kitchens, bathrooms and all water taps, as well as the recycling of rain and the secondhand intermediate water.2.1. Goal of using the water conservation indexAlthough Taiwan has plenty of rain, due to its large population, the average rainfall for distribution to each individual is poor compared to the world average as shown in Fig. 1.Thus, Taiwan is reversely a country short of water. Yet, the recen t improvements in citizens’ standards of living have led to a big increase in the amount of water needed in cities, as shown in Fig. 2, which, accompanied by the difficulty of obtaining new water resources, makes the water shortage problem even worse. Due to the improper water facilities designs in the past, the low water fee, and the usual practical behavior of people when using water, Taiwanesepeople have tended to use a large quantity of tap water. In 1990,the average water-consumption quantity in Taiwan was 350l per person per day, whereas in Germany it is about 145l per person per day, and in Singapore about 150l per person per day. These statistics reveal the need for Taiwanese people to save water.The promotion of better-designed facilities which facilitate water-saving will become a new trend among the public and designers, because of concerns for environmental protection. The water conservation index was also designed to encourage utilization of the rain, recycling of water used in everyday life and use of water-saving equipment to reduce the expenditure of water and thus save water resources.2.2. Methodology for efficient use of water resourcesSome construction considerations and building system designs for effective use of water resources are described below.2.2.1. Use water-conservation equipmentA research of household tap-water consumption revealed that the proportion of the water used in flushing toilets and in bathing, amounts to approximately 50% of the total household water consumption, as given in Table 1. Many construction designers have tended to use luxurious water facilities in housing, and much water has thus been wasted. The use of water-saving equipment to replace such facilities is certain to save a large amount of water. For example, the amounts of water used in taking a shower and having a bath is quite different.A single shower uses around 70l of water, whereas a bath uses around 150l. Furthermore, current construction designs for housing in Taiwan tend to put two sets of bathtubs and toilets, and quite a few families have their own massage bathtubs. Such a situation can be improved only by removing the tubs and replacing them with shower nozzles, so that more water can be possibly saved. The commonly used water-saving devices in Taiwan now include new-style water taps, water-saving toilets, two-sectioned water closets, water-saving shower nozzles, and auto-sensor flushing device systems, etc. Water-saving devices can be used not only for housing, but also in other kinds of buildings. Public buildings, in particular, should take the lead in using water-saving devices.2.2.2. Set up a rain-storage water supply deviceThe rain-storage water supply device stores rain using natural landforms or man-made devices, and then uses simple water-cleaning procedures to make it available for use in houses. Rain can be used not only as a substitute water supply, but also for re control. Its use also helps to decrease the peak-time water load in cities. The annual average rainfall in Taiwan is about 2500 mm, almost triple better than the global average. However, due to geographic limitations, we could not build enough water storage devices, such as dams, to save all the rain. It is quite a pity that annually about 80% of the rain in Taiwan is wasted and flows directly into the sea, without being saved and stored. The rain-storage water supply system is used with a water-gathering system, water-disposal system, water-storage system and water-supply system. First, the water-gathering system gathers the rain. Then, the water flows to the water-disposal system through pipes, before being sent to the water-storage system. Finally, it is sent to the users’equipment through another set of pipes. Using the drain on the roof of a building, leading to the underground water-storage trough, is considered an effective means of gathering rain. The water, after simple water-disposal processes, can be used for chores such as house cleaning, washing floors, air-conditioning or watering plants.2.2.3. Establishing the intermediate water systemIntermediate water is that gathered from the rain in cities, and includes the recycled waste-water which has already been disposed of and can be used repeatedly only within a certain range, but not for drinking or human contact. Flushing the toilet consumes 35% of all water. If everyone were to use intermediate water to flush toilets, much water could be efficiently saved. Large-scale intermediate water system devices are suggested to be built up regularly with in a big area. Each intermediate water system device can gather, dispose and recycle a certain quantity of waste-water from nearby government buildings, schools, residences, hotels, and other buildings. The obtained water can be used for flushing toilets, washing cars, watering plants and cleaning the street, or for garden use and to supplement the water of rivers or lakes. A small-scale intermediate water system gathers waste-water from everyday use, and then, through appropriate water-disposal procedures, improves the water quality to a certain level, so that finally it can be repeatedly used for non-drinking water. Thereare extensive ways to use the intermediate water. It can be used for sanitary purposes, public fountains, watering devices in gardens and washing streets. In order to recycle highly polluted waste-water, a higher cost is needed for setting up the associated water-disposal devices, which are more expensive and have less economic benefits than the rain-utilization system. Except for the intermediate water-system set within a single building, if we build them within large-scale communities or major construction development programs, then it is sure to save more water resources efficiently and positively for the whole country as well as improve the environmental situation.4. Method for assessing the recycling of rainSystems for recycling rain and intermediate water are not yet economic beneficial, because of the low water fee and the high cost of water-disposal equipment. However, systems for recycling rain are considered more easily adoptable than those for recycling intermediate water. Herein, a method for assessing the recycling of rain is introduced to calculate the ratio (C) of the water-consumption quantity of the recycled rainwater to the total water-consumption.4.1. Calculation basis of recycling rainwaterThe designer of a system for recycling rainwater must first determine the quantity of rainwater and the demand, which will determine the rainwater collection device area and the storage tank volume. Rainwater quantity can actually be determined by a simple equation involving precipitation and collection device area. However, precipitation does not fall evenly spread over all days and locations. In particular, rain is usually concentrated in certain seasons and locations. Consequently, the critical point of the evaluation is to estimate and assess meteorological precipitation. Meteorological records normally include yearly, monthly, daily and hourly precipitation. Yearly and monthly precipitation is suitable for rough estimates and initial assessment. However, such approximation creates problems in determining the area of the rainwater collection device and the volume of the storage tank. Thus, daily precipitation has been most commonly considered. Hourly precipitation could theoretically support a more accurate assessment. However, owing to the increasing number of parameters and calculation data increases, the complexity of the process and the calculation time, result in inefficiencies. Herein, daily precipitation is adoptedin assessing rainwater systems used in buildings [4,7].4.3. Case study and analysisFollowing the above procedure, a primary school building with a rainwater use system is taken as an example for simulation and to verify the assessment results. This building is located in Taipei city, has a building area of 1260 m and a total floor area of 6960 m ; it is a multi-discipline teaching building. Roofing is estimated to cover 80% of the building area, and the rainwater collection area covers 1008 m .Rainwater is used as intermediate water for the restrooms, and the utilization condition is set at 20 m per day, whilethe out flow coefficient (Y) is 0.9. A typical meteorological precipitation in Taipei in 1992 was adopted as a database. The rainwater storage tank was set to an initial condition before the simulation procedure. Herein, four tank volumes were considered in the simulations of rainwater utilization—15, 25, 50, 100 m. The results indicate that increased storage tank volume reduces overflow and increases the utilization of rainwater. Given a 50 m storage tank, the quantity of rainwater collection closely approaches the utilization quantity of rainwater. Consequently, this condition obtains a storage tank with a roughly adequate volume. When the volume of the storage tank is 100 m, the utilization rate is almost 100% and the overflow quantity approaches zero. Despite this result being favorable with respect to utilization, such a tank may occupy much space and negatively impact building planning. Consequently, the design concept must balance all these factors. The building in this case is six floors high, and the roof area is small in comparison to the total floor area. The water consumption of the water closet per year, but the maximum rainwater approaches 7280 m collection is 2136 m per year. Thus, significant replenishment from tap water is required. This result also leads to a conclusion that high-rise buildings use rainwater systems less efficiently than other buildings. Lower buildings (e.g. less than three floors) have highly efficient rainwater utilization and thus little need for replenishment of water from the potable water system.The efficiency of rainwater storage tanks is assessed from the utilization rate of rainwater and the substitution rate of tap water. Differences in annual precipitation and rainfall distribution yield different results. Figs. 5 and 6 illustrate the results of the mentioned calculation procedure, to analyze differences in rainwater utilization and efficiency assessment.The simulation runs over a period often years, from 1985 to 1994, and includes storage tanks with four different volumes. When the volume of the rainwater tank is 50 m, the utilization rate of rainwater exceeds 80% with about 25% substitution with tap water. Using this approach and the assessment procedure, the volume of rainwater storage and the performance of rainwater use systems in building design, can be determined.In the formula of the water conservation index, C is a special weighting for some water recycling equipment that intermediates water or rain, and is calculated as the ratio of the water-consumption quantity of the recycled rainwater to the total water-consumption. Therefore, this assessment procedure can also offer an approximate value of C for the water conservation index.5. Green building label and policy“Green Building” is called “Environmental Co-Habitual Architecture” in Japan, “Ecological Building” or “Sustainable Building” in Europe and “Green Build ing in North American countries. Many fashionable terms such as “Green consumption”, “Green living”, “Green illumination” have been broadly used. In Taiwan, currently, “Green” has been used as a symbol of environmental protection in the country. The Construction Research Department of the Ministry of the Interior of the Executive Yuan has decided to adopt the term “Green Building” to signify ecological and environmental protection architecture in Taiwan.5.1. Principles of evaluationGreen Building is a general and systematic method of design to peruse sustainable building. This evaluation system is based on the following principles:(1) The evaluation index should accurately reflect environmental protection factors such as material, water, land and climate.(2) The evaluation index should involve standardized scientific quantification.(3) The evaluation index should not include too many evaluation indexes; some similar quality index should be combined.(4) The evaluation index should be approachable and consistent with real experience.(5) The evaluation index should not involve social scientific evaluation.(6) The evaluation index should be applicable to the sub-tropical climate of Taiwan.(7) The evaluation index should be applicable to the evaluation of community or congregate construction.(8) The evaluation index should be usable in the pre-design stage to yield the expected result.According to these principles, the seven-index system shown in Table 4 is the current Green Building evaluation system use d in Taiwan. The theory evaluates buildings’ impacts on the environment through the interaction of “Earth Resource Input” and “Waste Output”. Practically, the definition of Green Building in Taiwan is “Consume the least earth resource and create the least construction waste”.Internationally, each country has a different way of evaluating Green Building. This system provides only the basic evaluation on “Low environment impact”. Higher level issues such as biological diversity, health and comfort and community consciousness will not be evaluated. This system only provides a basic, practical and controllable environmental protection tool for inclusion in the government’s urgent construction environment protection policy. The “Green Building” logo is set to a ward Green Building design and encourage the government and private sector to pay attention to Green Building development. Fig. 7 is the logo of Green Building in Taiwan [6,8].5.2. Water conservation measureThis paper focuses on water conservation index in green building evaluation system. Water conservation is a critical category of this evaluation system, and is considered in relation to saving water resources through building equipment design. This evaluation index contains standardized scientific quantification and can be used in the pre-design stage to obtain the desired result. The evaluation index is also based on research in Taiwan and is practically applicable. Using water-saving equipment is the most effective way of saving water; using two-sectioned water-saving toilets and water-saving showering devices without a bathtub are especially effective. Various other types of water-recycling equipment for reusing intermediate water and rain are also evaluated. In particular, rainwater-use systems in building designs areencouraged. When a candidate for a Green Building project introduces water recycling system or a rainwater use system, the applicant should propose an appropriate calculation report to the relevant committee to verify its water-saving efficiency. This guideline actually appears to be a reasonable target for performing Green Building policy in Taiwan.A new building can easily reach the above water conservation index. This evaluation system is designed to encourage people to save more water, even in existing buildings. All this amounts to saying that large-scale government construction projects should take the lead in using such water-saving devices, as an example to society.6. ConclusionThis paper introduces the Green Building program and proposes a water conservation index with standardized scientific quantification. This evaluation index contains standardized scientific quantification and can be used in the pre-design stage to obtain the expected results. The measure of evaluation index is also based on the essential research on Taiwan and is a practical and applicable approach. The actual water-saving rate (WR) for Green Building projects should be <0.8, and the AR of the water-saving equipment should be higher than 0.8. Thus, qualified Green Building projects should achieve a water saving rate of over 20%. For the sustainable policy, this program is aimed not only at saving water resources, but also at reducing the environmental impact on the earth.The Green Building Label began to be implemented from 1st September 1999, and over twenty projects have already been awarded the Green Building Label in Taiwan, while the number of applications continues to increase.

节约用水的具体措施英语作文Water conservation is a crucial issue that affects us all, as the availability of clean and accessible water is essential for sustaining life on our planet. As the global population continues to grow, the demand for water has increased significantly, putting a strain on our limited water resources. It is imperative that we take concrete steps to conserve water and ensure a sustainable future for generations to come.One of the most effective ways to conserve water is to address our daily water usage habits. In the household, simple adjustments can make a significant impact. For instance turning off the tap while brushing our teeth or shaving can save up to 6 liters of water per minute. Taking shorter showers, rather than baths, can reduce water consumption by as much as 50%. Additionally, fixing leaks in faucets and pipes can prevent the loss of thousands of liters of water per year.Another important measure is to be mindful of our water-usage when performing household chores. Washing dishes by hand can use up to 100 liters of water, while a modern, energy-efficient dishwasher can use as little as 15 liters per cycle. Similarly, using a washingmachine with a full load rather than multiple small loads can save a significant amount of water. Gardeners can also play a crucial role by selecting drought-resistant plants, using drip irrigation systems, and watering during the cooler parts of the day to minimize evaporation.In the agricultural sector, which accounts for the largest share of global water usage, there are several strategies that can be implemented to conserve water. Adopting precision irrigation techniques, such as drip irrigation or micro-sprinklers, can reduce water consumption by up to 60% compared to traditional flood irrigation methods. Utilizing mulch to retain soil moisture, and implementing crop rotation and cover cropping practices, can also contribute to water conservation efforts.The industrial sector is another area where significant water savings can be achieved. Implementing water-efficient technologies, such as closed-loop water recycling systems and water-free manufacturing processes, can greatly reduce the amount of water required for industrial operations. Additionally, companies can invest in water audits to identify and address areas of water waste, and implement employee training programs to promote water-saving practices.At the community level, public education and awareness campaigns can play a vital role in promoting water conservation. Providing information on simple water-saving tips, the importance of waterconservation, and the impact of individual actions can empower citizens to make informed decisions and adopt sustainable water-use habits.Governments and policymakers also have a crucial role to play in water conservation. Implementing stricter regulations, offering incentives for water-efficient technologies, and investing in infrastructure improvements, such as upgrading water treatment and distribution systems, can all contribute to more sustainable water management.In conclusion, conserving water is a shared responsibility that requires a multi-faceted approach involving individuals, communities, businesses, and governments. By adopting concrete measures, such as reducing household water usage, implementing water-efficient agricultural and industrial practices, and supporting public education and policy initiatives, we can collectively work towards a more sustainable water future. It is our duty to safeguard this precious resource for the benefit of present and future generations.。
阐述绿色建筑给排水设计的节水措施一、建筑给排水设计存在的问题1、选择了不恰当的热水供应循环方式目前,在我国的水资源浪费现象中,由于热水供应系统设计部合理导致的浪费较为严重,其主要表现在使用热水之前的冷水排放方面,例如家用热水器等,随着生活水平的提高,家用热水器已经很普遍了,尤其是在夏季,更多的人选择在家洗澡,而在使用热水的时候,打开开关不能立刻得到想要的水温,所以需要进行调节,而在调节过程中通常是通过放掉部分冷水之后达到要求的水温。
而这部分流失的冷水,则未产生其应发挥的使用功效,也就成为了浪费的水量。
造成此种水资源浪费的原因有施工与管理不当、设计不足,以及受经济条件制约等因素。
从设计的角度出发,选择正确的热水循环方式很重要。
根据相关调查数据显示,干管循环方式浪费的水量是最多的,比较节水的循环方式是采用支管、立管和干管。
所以,在集中的热水供应系统中建议设计确保干管和立管中的热水循环方式。
2、管道、阀门的泄漏问题由于管道老化和生锈,使管道在管子的接缝处及法兰、阀门的连接处向外冒水;由于阀门的质量较差,浮球阀损坏或漏水,使水直接从中流出,最终导致造成了大量的水资源被浪费。
另外,若埋在地下的管道发生漏水或在某种作用下爆裂也将造成极大的水资源浪费。
3、使用的卫生器具浪费水我国之前经常使用的部分老式卫生器具以及配水器具的设计都属于费水比较严重的形式。
例如一些旧式建筑中使用的老式高水位蹲式大便器,在冲洗的时候是将水箱中的水一次排出进行,而这些水箱在设计的时候都比较大,有一些冲水量高达12L/s,这在使用过程中浪费了大量的水资源。
4、消防加压贮水系统设计不合理目前,大部分的高层住宅楼以及办公楼是各个单元进行单独加压的消防加压方式,这种加压方式将造成设备投资及工程建设的相关费用较高,且多座贮水池需要大量的定期换水,也造成了大量的水资源浪费。
5、中水综合利用率较低中水是指各种排水经过相应的处理之后,在生活、市政以及环境等范围内可以使用的杂用的非饮用水,即达到符合规定标准的水质。

关键词:绿色建筑;给排水;设计;节水措施1浅析建筑节水的重要性上世纪70年代,我国出现了水资源短缺的现象,而且这种现象还在继续恶化。
从现阶段我国水资源的不完全统计数据可以看出,我国水资源极度匮乏,已成为缺水国家之一。
通过对历史资料的研究,我们可以清楚地看到,在未来的发展中,必须严格要求和控制水流和水质,以达到水资源利用效率最大化的目标。
运用科学的方法提高水资源利用效率,合理配置水资源,可以节约用水,减少水资源的过渡性消耗、污染和浪费。
在当前城市发展中,必须把提高水资源利用率作为一项重要的研究内容,提高人们的节水意识,把节水理念落实到各行各业的建设中。
绿色建筑中的节水环保理念非常重要。
为实现这一目标,在工程建设过程中,应采用节水型设备,减少水资源的损失;完善污水处理环节,回收废水,提高废水的利用率;节水标准和措施应严格按照绿色建筑的设计切实执行。
2建筑给排水应用中的水资源浪费分析2.1泄漏问题及原因分析建设项目建成后,排水系统在日常运行过程中最严重的问题就是渗漏现象,造成水资源的严重浪费。
造成这一问题的直接原因是:在设计之初,排水系统的相关线路没有根据工程实际情况进行合理的规划设计,导致管道敷设和选型与实际情况发生偏差,进而出现渗漏问题;在排水系统施工的各个方面,管道之间接口的缺陷或损坏会导致水资源的泄漏和浪费;管道及其附件的质量问题导致长期使用时无法承受外部环境的腐蚀,这大大缩短了排水系统的使用寿命,造成了渗漏问题,也导致了水资源的大量浪费。
绿色建筑节水措施的评价及应用优化研究绿色建筑在发展期间主要是根据我国提出的可持续发展政策来实施的,在水资源利用过程中通过中水回用提高水的循环性和利用率中水处理,从而实现水资源的综合利用。
要达到绿色建筑的节水目的,就要对给水、排水、雨水系统进行设计,从而实现整体的节能减排效果。
在本文中,主要对绿色建筑中采用的节水措施进行评价,保证系统应用的优化。
标签:绿色建筑;节水措施;评价;优化引言:绿色建筑是指在建筑的全寿命周期内,最大限度节约资源,节能、节地、节水、节材、保护环境和减少污染,提供健康适用、高效使用,与自然和谐共生的建筑。
绿建的推广能够促进人与自然和谐发展,减少建筑物在发展期间对污染物的排放,在以人为本建立方式中为人们创造绿色、健康的环境空间。
一、绿色建筑节水评价方法(一)模糊综合评判模糊综合评价主要是在模糊的环境中对多种影响因素进行讨论,在一定目的条件下利用综合评判方法进行决策。
人们在现实社会发展中,由于每天接触的因素、指标以及目标等评价方式都比较多,所以系统在恢复形式上也增加了复杂性,很多不精确、不确定的系统描述也在增加[1]。
在这些不确定因素中,一些是随机的,一些是模糊的,人们在判断以及推理方式上逐渐变得模糊。
模糊综合判断在系统判断过程是根据人脑思维来决定的,在检验过程中,它应用于各行各业。
模糊评价法用于绿色建筑节水评价,可以综合评价建筑的节水节能效益,评价过程简单、结论简单直观。
(二)层次分析法层次分析法主要将复杂的系统进行层次分析,主要在目标、准则以及方案等层次上进行分析,然后根据各个层次问题进行定性以及定量分析等方法。
在人的思想决策上,将人的思想进行层次化、数量化以及模型化实现分析以及解决的。
该方法在管理评价、经济发展建设中能够对资源进行规划,对发生的事故因素进行分析等方式,还能对人的基本素质进行评价,从而保证经济发展的全面性。
绿色建筑的层次分析,是将建筑的给水、排水、雨水系统分别评价,分别考虑各个组成系统的效益,其评价结论更详尽。

外文文献:Evaluating Water Conservation Measures For Green Building InTaiwanGreen Building evaluation is a new system in which water conservation is prioritized as one of its seven categories for saving water resources through building equipment design in Taiwan. This paper introduces the Green Building program and proposes a water conservation index with quantitative methodology and case study. This evaluation index involves standardized scientific quantification and can be used in the pre-design stage to obtain the expected result. The measure of evaluation index is also based on the essential researchin Taiwan and is a practical and applicable approach.Keywords: Green Building; Evaluation system; Water conservation; Building equipment1. IntroductionThe environment was an issue of deep global concern throughout the latter half of the 20th century. Fresh water shortages and pollution are becoming one of the most critical global problems. Many organizations and conferences concerning water resource policy and issues have reached the consensus that water shortages may cause war in the 21st century[1],if not a better solution .Actually, Taiwan is already experiencing significant discord over water supply. Building new dams is no longer an acceptable solution to the current water shortage problems, because of the consequent environmental problems. Previous studies have concludedthat water savings are necessary not only for water conservation but also for reducing energy consumption [2,3].Taiwan is located in the Asian monsoon area and has an abundant supply of rainwater. Annual precipitation averages around 2500mm. However, water shortages have recently been a critical problem during the dry season. The crucial, central issue is the uneven distribution of torrential rain, steep hillsides, and short rivers. Furthermore, the heavy demand for domestic water use in municipal areas, and the difficulties in building new reservoirs are also critical factors. Government departments are endeavoring to spread publicly the concept of water-conservation. While industry and commerce have made excellent progress in waterconservation, progress among the public has been extremely slow.Due to this global trend, the Architecture and Building Research Institute (ABRI), Ministry of Interior in Taiwan, proposed the “Green Building” concept and built the evaluation system. In order to save water resources through building equipment design, this system prioritizes water conservation as one of its seven categories. This paper focuses on the water conservation measures for Green Building in Taiwan and a quantitative procedure for proving water-saving efficiency. The purpose of this work is not only aimed at saving water resources, but also at reducing the environmentalimpact on the earth.2. Water conservation indexThe water conservation index is the ratio of the actual quantity of water consumed in a building to the average water-consumption in general. The index is also called, “the water saving rate”. Evaluations of t he water-consumption quantity include the evaluation to the water-saving efficiency within kitchens, bathrooms and all water taps, as well as the recycling of rain and the secondhand intermediate water.2.1. Goal of using the water conservation indexAlthough Taiwan has plenty of rain, due to its large population, the average rainfall for distribution to each individual is poor compared to the world average as shown in Fig. 1.Thus, Taiwan is reversely a country short of water. Yet, the recent improvements i n citizens’ standards of living have led to a big increase in the amount of water needed in cities, as shown in Fig. 2, which, accompanied by the difficulty of obtaining new water resources, makes the water shortage problem even worse. Due to the improper water facilities designs in the past, the low water fee, and the usual practical behavior of people when using water, Taiwanese people have tended to use a large quantity of tap water. In 1990,the average water-consumption quantity in Taiwan was 350l per person per day, whereas in Germany it is about 145l per person per day, and in Singapore about 150l per person per day. These statistics reveal the need for Taiwanese people to save water.The promotion of better-designed facilities which facilitate water-saving will become anew trend among the public and designers, because of concerns for environmental protection. The water conservation index was also designed to encourage utilization of the rain, recycling of water used in everyday life and use of water-saving equipment to reduce the expenditure of water and thus save water resources.2.2. Methodology for efficient use of water resourcesSome construction considerations and building system designs for effective use of water resources are described below.2.2.1. Use water-conservation equipmentA research of household tap-water consumption revealed that the proportion of the water used in flushing toilets and in bathing, amounts to approximately 50% of the total household water consumption, as given in Table 1. Many construction designers have tended to use luxurious water facilities in housing, and much water has thus been wasted. The use of water-saving equipment to replace such facilities is certain to save a large amount of water. For example, the amounts of water used in taking a shower and having a bath is quite different.A single shower uses around 70l of water, whereas a bath uses around 150l. Furthermore, current construction designs for housing in Taiwan tend to put two sets of bathtubs and toilets, and quite a few families have their own massage bathtubs. Such a situation can be improved only by removing the tubs and replacing them with shower nozzles, so that more water can be possibly saved. The commonly used water-saving devices in Taiwan now include new-style water taps, water-saving toilets, two-sectioned water closets, water-saving shower nozzles, and auto-sensor flushing device systems, etc. Water-saving devices can be used not only for housing, but also in other kinds of buildings. Public buildings, in particular, should take the lead in using water-saving devices.2.2.2. Set up a rain-storage water supply deviceThe rain-storage water supply device stores rain using natural landforms or man-made devices, and then uses simple water-cleaning procedures to make it available for use in houses. Rain can be used not only as a substitute water supply, but also for re control. Its use also helps to decrease the peak-time water load in cities. The annual average rainfall in Taiwan is about2500 mm, almost triple better than the global average. However, due to geographic limitations, we could not build enough water storage devices, such as dams, to save all the rain. It is quite a pity that annually about 80% of the rain in Taiwan is wasted and flows directly into the sea, without being saved and stored. The rain-storage water supply system is used with a water-gathering system, water-disposal system, water-storage system and water-supply system. First, the water-gathering system gathers the rain. Then, the water flows to the water-disposal system through pipes, before being sent to the water-storage system. Finally, it is sent to the users’equipment through another set of pipes. Using the drain on the roof of a building, leading to the underground water-storage trough, is considered an effective means of gathering rain. The water, after simple water-disposal processes, can be used for chores such as house cleaning, washing floors, air-conditioning or watering plants.2.2.3. Establishing the intermediate water systemIntermediate water is that gathered from the rain in cities, and includes the recycled waste-water which has already been disposed of and can be used repeatedly only within a certain range, but not for drinking or human contact. Flushing the toilet consumes 35% of all water. If everyone were to use intermediate water to flush toilets, much water could be efficiently saved. Large-scale intermediate water system devices are suggested to be built up regularly with in a big area. Each intermediate water system device can gather, dispose and recycle a certain quantity of waste-water from nearby government buildings, schools, residences, hotels, and other buildings. The obtained water can be used for flushing toilets, washing cars, watering plants and cleaning the street, or for garden use and to supplement the water of rivers or lakes. A small-scale intermediate water system gathers waste-water from everyday use, and then, through appropriate water-disposal procedures, improves the water quality to a certain level, so that finally it can be repeatedly used for non-drinking water. There are extensive ways to use the intermediate water. It can be used for sanitary purposes, public fountains, watering devices in gardens and washing streets. In order to recycle highly polluted waste-water, a higher cost is needed for setting up the associated water-disposal devices, which are more expensive and have less economic benefits than the rain-utilization system. Except for the intermediate water-system set within a single building, if we build them withinlarge-scale communities or major construction development programs, then it is sure to save more water resources efficiently and positively for the whole country as well as improve the environmental situation.4. Method for assessing the recycling of rainSystems for recycling rain and intermediate water are not yet economic beneficial, because of the low water fee and the high cost of water-disposal equipment. However, systems for recycling rain are considered more easily adoptable than those for recycling intermediate water. Herein, a method for assessing the recycling of rain is introduced to calculate the ratio (C) of the water-consumption quantity of the recycled rainwater to the total water-consumption.4.1. Calculation basis of recycling rainwaterThe designer of a system for recycling rainwater must first determine the quantity of rainwater and the demand, which will determine the rainwater collection device area and the storage tank volume. Rainwater quantity can actually be determined by a simple equation involving precipitation and collection device area. However, precipitation does not fall evenly spread over all days and locations. In particular, rain is usually concentrated in certain seasons and locations. Consequently, the critical point of the evaluation is to estimate and assess meteorological precipitation. Meteorological records normally include yearly, monthly, daily and hourly precipitation. Yearly and monthly precipitation is suitable for rough estimates and initial assessment. However, such approximation creates problems in determining the area of the rainwater collection device and the volume of the storage tank. Thus, daily precipitation has been most commonly considered. Hourly precipitation could theoretically support a more accurate assessment. However, owing to the increasing number of parameters and calculation data increases, the complexity of the process and the calculation time, result in inefficiencies. Herein, daily precipitation is adoptedin assessing rainwater systems used in buildings [4,7].4.3. Case study and analysisFollowing the above procedure, a primary school building with a rainwater use system is taken as an example for simulation and to verify the assessment results. This building islocated in Taipei city, has a building area of 1260 m and a total floor area of 6960 m ; it is a multi-discipline teaching building. Roofing is estimated to cover 80% of the building area, and the rainwater collection area covers 1008 m .Rainwater is used as intermediate water for the restrooms, and the utilization condition is set at 20 m per day, whilethe out flow coefficient (Y) is 0.9. A typical meteorological precipitation in Taipei in 1992 was adopted as a database. The rainwater storage tank was set to an initial condition before the simulation procedure. Herein, four tank volumes were considered in the simulations of rainwater utilization—15, 25, 50, 100 m. The results indicate that increased storage tank volume reduces overflow and increases the utilization of rainwater. Given a 50 m storage tank, the quantity of rainwater collection closely approaches the utilization quantity of rainwater. Consequently, this condition obtains a storage tank with a roughly adequate volume. When the volume of the storage tank is 100 m, the utilization rate is almost 100% and the overflow quantity approaches zero. Despite this result being favorable with respect to utilization, such a tank may occupy much space and negatively impact building planning. Consequently, the design concept must balance all these factors. The building in this case is six floors high, and the roof area is small in comparison to the total floor area. The water consumption of the water closet per year, but the maximum rainwater approaches 7280 m collection is 2136 m per year. Thus, significant replenishment from tap water is required. This result also leads to a conclusion that high-rise buildings use rainwater systems less efficiently than other buildings. Lower buildings (e.g. less than three floors) have highly efficient rainwater utilization and thus little need for replenishment of water from the potable water system.The efficiency of rainwater storage tanks is assessed from the utilization rate of rainwater and the substitution rate of tap water. Differences in annual precipitation and rainfall distribution yield different results. Figs. 5 and 6 illustrate the results of the mentioned calculation procedure, to analyze differences in rainwater utilization and efficiency assessment. The simulation runs over a period often years, from 1985 to 1994, and includes storage tanks with four different volumes. When the volume of the rainwater tank is 50 m, the utilization rate of rainwater exceeds 80% with about 25% substitution with tap water. Using this approach and the assessment procedure, the volume of rainwater storage and the performance ofrainwater use systems in building design, can be determined.In the formula of the water conservation index, C is a special weighting for some water recycling equipment that intermediates water or rain, and is calculated as the ratio of the water-consumption quantity of the recycled rainwater to the total water-consumption. Therefore, this assessment procedure can also offer an approximate value of C for the water conservation index.5. Green building label and policy“Green Building” is called “Environmental Co-Habitual Architecture” in Japan, “Ecological Building” or “Sustainable Building” in Europe and “Green Building in North Ame rican countries. Many fashionable terms such as “Green consumption”, “Green living”, “Green illumination” have been broadly used. In Taiwan, currently, “Green” has been used as a symbol of environmental protection in the country. The Construction Research Department of the Ministry of the Interior of the Executive Yuan has decided to adopt the term “Green Building” to signify ecological and environmental protection architecture in Taiwan.5.1. Principles of evaluationGreen Building is a general and systematic method of design to peruse sustainable building. This evaluation system is based on the following principles:(1) The evaluation index should accurately reflect environmental protection factors such as material, water, land and climate.(2) The evaluation index should involve standardized scientific quantification.(3) The evaluation index should not include too many evaluation indexes; some similar quality index should be combined.(4) The evaluation index should be approachable and consistent with real experience.(5) The evaluation index should not involve social scientific evaluation.(6) The evaluation index should be applicable to the sub-tropical climate of Taiwan.(7) The evaluation index should be applicable to the evaluation of community or congregateconstruction.(8) The evaluation index should be usable in the pre-design stage to yield the expected result.According to these principles, the seven-index system shown in Table 4 is the current Green Building evaluation system used in Taiwan. The theory evaluates buildings’ impacts on the environment through the interaction of “Earth Resource Input” and “Waste Output”. Practically, the definition of Green Building in Taiwan is “Consume the least earth resource and create the least construction was te”.Internationally, each country has a different way of evaluating Green Building. This system provides only the basic evaluation on “Low environment impact”. Higher level issues such as biological diversity, health and comfort and community consciousness will not be evaluated. This system only provides a basic, practical and controllable environmental protection tool for inclusion in the government’s urgent construction environment protection policy. The “Green Building” logo is set to award Green Build ing design and encourage the government and private sector to pay attention to Green Building development. Fig. 7 is the logo of Green Building in Taiwan [6,8].5.2. Water conservation measureThis paper focuses on water conservation index in green building evaluation system. Water conservation is a critical category of this evaluation system, and is considered in relation to saving water resources through building equipment design. This evaluation index contains standardized scientific quantification and can be used in the pre-design stage to obtain the desired result. The evaluation index is also based on research in Taiwan and is practically applicable. Using water-saving equipment is the most effective way of saving water; using two-sectioned water-saving toilets and water-saving showering devices without a bathtub are especially effective. Various other types of water-recycling equipment for reusing intermediate water and rain are also evaluated. In particular, rainwater-use systems in building designs are encouraged. When a candidate for a Green Building project introduces water recycling system or a rainwater use system, the applicant should propose an appropriate calculation report to the relevant committee to verify its water-saving efficiency. This guideline actually appears to be areasonable target for performing Green Building policy in Taiwan.A new building can easily reach the above water conservation index. This evaluation system is designed to encourage people to save more water, even in existing buildings. All this amounts to saying that large-scale government construction projects should take the lead in using such water-saving devices, as an example to society.6. ConclusionThis paper introduces the Green Building program and proposes a water conservation index with standardized scientific quantification. This evaluation index contains standardized scientific quantification and can be used in the pre-design stage to obtain the expected results. The measure of evaluation index is also based on the essential research on Taiwan and is a practical and applicable approach. The actual water-saving rate (WR) for Green Building projects should be <0.8, and the AR of the water-saving equipment should be higher than 0.8. Thus, qualified Green Building projects should achieve a water saving rate of over 20%. For the sustainable policy, this program is aimed not only at saving water resources, but also at reducing the environmental impact on the earth.The Green Building Label began to be implemented from 1st September 1999, and over twenty projects have already been awarded the Green Building Label in Taiwan, while the number of applications continues to increase. For a country with limited resources and a high-density population like Taiwan, the Green Building policy is important and represents a positive first step toward reducing environmental impact and promoting sustainable development.中文译文:台湾的绿色建筑节约用水评价措施在台湾绿色建筑评价是一个新的制度,在它的一个7个类别中,通过建筑设备设计节省水资源,使水资源保护置于优先地位。
