台湾的绿色建筑

独树一帜的台湾绿色建筑作者：李强来源：《海峡科技与产业》2011年第08期据台湾媒体报道，台湾共有2818栋绿色建筑，若以密度计算，台湾绿色建筑密度位居全球第一，这些绿色建筑每年共节电8.9亿度，节水3.6963亿吨，回收二氧化碳5.99亿吨，节省经费25亿元新台币。

台湾资源贫乏，日常生活中98%的能源必须依赖进口，其中建筑占28%，故台湾自1999年起便开始推动节能减碳的绿色建筑。

初期的时候，台湾的建筑设计多沿袭国外；后来设计师发现，欧美的寒带建筑造型并不适合台湾的湿热气候，如无遮阳功效的玻璃温室或水平大天窗这样的设计，只会更加浪费空调耗费的电力，并不能真正达到节能的目的。

因此建筑师们开始思考：要怎么样才能将建筑与台湾的自然生态结合？跟台湾的有机农业的认证一样，绿色建筑也有它评估的标准。

台湾绿色建筑的定义是“生态、节能、减废、健康的建筑物”。

为鼓励兴建省能源、省资源、低污染之绿色建筑，台政府公告受理“绿建筑标章”申请，标章的审核需进行绿色建筑九大指标系统的评估，包括绿化量指标、基地保水指标、水资源指标、日常节能指标、二氧化碳减量指标、废弃物减量指标、污水垃圾改善指标、生物多样性指标与室内环境指标。

其中只要建筑物本身符合两个标准以上的都可以被称作绿建筑；等级由合格至最优等，依序分为合格级、铜级、银级、黄金级、钻石级等五级。

绿色图书馆——台北市图书馆北投分馆台北市图书馆北投分馆是台湾首座绿建筑图书馆，而且获得台湾绿建筑最高荣誉“钻石级”的殊荣。

图书馆由于地处温泉水脉，可避免硫磺气的侵蚀，建物使用木材及钢材，而且建材皆可回收再利用，减少废弃物对环境的破坏。

图书馆外墙采用大量阳台深遮阳及垂直木格栅，减少热辐射进入室内，降低耗能达到节能效果。

图书馆屋顶为轻质生态屋顶，设有太阳能发电板，设置容量为16KW电力，可用于景观照明的电力来源。

而斜坡屋顶设计可涵养水分自然排水至雨水回收槽，再利用回收水浇灌植栽及冲水马桶，达到绿化与减少水资源浪费。

使建筑融入自然与地域的气候环境——浅析台湾地区的绿色建筑摘要：本文从自然、地域气候环境角度出发，主要阐述了台湾地区的绿色建筑，介绍其与自然、地域气候的关系，提出了使建筑融入自然与地域的气候环境的建筑设计理念，为东南亚热带气候地区绿色建筑的发展提供借鉴。

关键词：自然与地域气候环境台湾地区绿色建筑前言建筑是时代的一个产物，是社会的一个重要反映。

建筑设计是人类社会历史实践过程中创造的建筑物质和建筑精神财富的总和。

作为人与自然中介的建筑设计，同样要受到各种自然与地域气候环境的制约。

因此，可以说建筑风格的形成在某种程度上是由自然、地域建筑气候环境的特异性早就的。

1台湾地区绿色建筑综述台湾地区属于南亚热带气候区，在中国建筑气候区划图中属于IV A区（如下图）。

该区气候对建筑的基本要求是：（1）建筑必须充分满足防热、通风、防雨的要求，冬季可不考虑防寒、保温；（2）总体规划、单体设计、构造设计时应开敞通透，充分利用自然通风，以利于建筑被动降温；（3）建筑物应避免西晒，宜设遮阳，或采取水平和垂直绿化等遮阳措施；（4）应注意防暴雨、防洪、防潮、防雷击，在建筑小区和城市道路两侧设置骑楼或形成中庭等传统手法对此十分有益；（5）夏季施工应对应有防高温和暴雨的措施；（6）应注意防热带风暴和台风、暴雨袭击及盐雾侵蚀。

台湾地区自1995年首次将“建筑节约能源设计”纳入“建筑技术规则”以来，岛内逐步开展绿色建筑推广运动。

短短数年内，绿色建筑思潮不但在学术界、媒体界蔚为风气，更在社会生活的各个领域内引起了强烈地反响。

针对台湾建筑营造存在的种种与建筑气候环境不相适应的问题，绿色建筑推广运动提出了使建筑具有亚热带建筑文化风格的主张。

所谓亚热带建筑文化风格，最具体的建筑特征无非就是“适中的开口”、“丰富的阴影”等表情。

2台湾地区绿色建筑实例分析2.1台湾成功大学绿色魔法学校（1）项目简介台湾成功大学绿色魔法学校被称为“东方诺亚方舟”，是台湾环保界最引人注目的焦点项目，号称世界第一座“亚热带绿建筑教育中心”，2009年已经顺利取得台湾“钻石级绿建筑候选证书”之认证，预计将进而取得美国绿建筑协会“白金级绿建筑”的认证。

１．获“钻石级绿建筑”殊荣电子产业，曾被视为创造台湾经济奇迹的一匹黑马，事实上也可以成为保护地球的尖兵。

过去，大家总认为电子厂房是高耗能、高污染的建筑物，但台达南科厂（台达电子公司南部科学园区厂房办公大楼），却是一个标榜生态、节能、减排（低污染）、健康的绿色建筑教育实验场所。

由成功大学建筑研究所与石昭永建筑师合作设计的台达南科厂，是第一座获得台湾绿色建筑ＥＥＷＨ评估系统九大指标全部评估通过，且得到２００６年“黄金级绿色建筑标章”认证合格的建筑物，同时也获得台湾内政部“２００６年最佳优良绿建筑大奖”的肯定。

２００９年，它更以３年连续节能３４．５％的成效荣获“钻石级绿色建筑标章”的殊荣。

台湾的绿色建筑评估系统特别标榜亚热带特色，“适当的开口、丰富的阴影、充分的通风”正是台达南科厂最被凸显的风土特色，加上一座雕塑艺术的钢板结构玄关，让它看来犹如一座充满立体绿化与阴影变化的热带五星级观光旅馆，甚至常有来访南科的外宾，频频进来询问住宿的方法。

不过，得到“钻石级绿建筑”认证并不难，困难的是：如何保证“绿色建筑是不贵的”？庆幸的是，这栋建筑选择了最经济的绿色建筑技术，土木造价只花费新台币２．１２万元／ｍ２，在当时只是一般水平，但２００６年落成以来３年均能达到节能３４．５％（与台湾一般办公建筑ＥＵＩ１４８ｋＷｈ／（ｍ２．ａ）相比），并且３年来员工问卷调查的满意度均高于９５．０％。

这样的成果，并没有动用昂贵的高科技设备，只是设计了浮力通风中庭、深遮阳开窗、风雨玄关与野放生态密林而已，这些都是廉价、简单，但却有效益的生态设计手法。

所有的节能减碳效益，与２００４年当初成功大学建筑研究所的预期相差不远，节能效益预测３１．０％，只比实际相差３．５％，另外，营建废弃物减量效果高达１０％，日常节水效果高达５０％，也如期达成。

２．建筑节能设计重点２．１　亚热带的风土设计为了采用便宜、有效的节能技术，成功大学建筑研究所动用美国能源部的ＤＯＥ程序，针对新加坡、香港、台北、东京、上海、北京、哈尔滨等从热带到严寒的６种都市气候类型，以某栋地上１０层办公建筑物的围护结构因子对空调热负荷的影响进行变异数分析（表１），藉此探讨本案的建筑节能设计重点。

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。
