The objectives of the model were the minimum cost loss due to the delay of the time limit of the projects and the minimum delay of the project with the highest priority .Then a Genetic Algorithm to solve the model was introduced. Finally, a numerical example was used to testify the feasibility of the model and the algorithm.Index Terms—Genetic Algorithm, Human Resource Allocation, Multi-project’s project’s priority .1.INTRODUCTIONMore and more enterprises are facing the challenge of multi-project management, which has been the focus among researches on project management. In multi-project environment ,the share are competition of resources such as capital , time and human resources often occur .Therefore , it’s critical to schedule projects in order to satisfy the different resource demands and to shorten the projects’ duration time with resources constrained ,as in [1].For many enterprises ,the human resources are the most precious asset .So enterprises should reasonably and effectively allocate each resource , especially the human resource ,in order to shorten the time and cost of projects and to increase the benefits .Some literatures have discussed the resource allocation problem in multi-project environment with resources constrained. Reference [1] designed an iterative algorithm and proposeda mathematical model of the resource-constrained multi-project scheduling .Basedon work breakdown structure (WBS) and Dantzig-Wolfe decomposition method ,a feasible multi-project planning method was illustrated , as in [2] . References [3,4]discussed the resource-constrained project scheduling based on Branch Delimitation method .Reference [5] put forward the framework of human resource allocation in multi-project in Long-term ,medium-term and short-term as well as research and development(R&D) environment .Basedon GPSS language, simulation model of resources allocation was built to get the project’s duration time and resources distribution, as in [6]. Reference [7] solved the engineering project’s resources optimization problem using Genetic Algorithms. These literatures reasonably optimized resources allocation in multi-project, but all had the same prerequisite that the project’s importance is the same to each other .This paper will analyze the effects of project’s priority on human resource allocation ,which is to be introduced into a mathematical model ;finally ,a Genetic Algorithm is used to solve the model.2.EFFECTS OF PROJECTS PRIORITY ON HUMAN RESOUCE ALLOCATIONAND THE AFFECTING FACTORS OF PROJECT’S PRIORITYResource sharing is one of the main characteristics of multi-project management .The allocation of shared resources relates to the efficiency and rationality of the use of resources .When resource conflict occurs ,the resource demand of the project with highest priority should be satisfied first. Only after that, can the projects with lower priority be considered.Based on the idea of project classification management ,this paper classifies the affecting factors of project’s priority into three categories ,as the project’s benefits ,the complexity of project management and technology , and the strategic influence on the enterprise’s future development . The priority weight of the project is the function of the above three categories, as shown in (1).W=f(I,c,s…) (1)Where w refers to project’s priority weight; I refers to the benefits of th e project; c refers to the complexity of the project, including the technology and management; s refers to the influence of the project on enterprise .The bigger the values of the three categories, the higher the priority is.3.HUMAN RESOURCE ALLOCATION MODEL IN MULTI-PROJECTENVIRONMENT3.1Problem DescriptionAccording to the constraint theory, the enterprise should strictly differentiate the bottleneck resources and the non-bottleneck resources to solve the constraint problem of bottleneck resources .This paper will stress on the limited critical human resources being allocated to multi-project with definite duration times and priority.To simplify the problem, we suppose that that three exist several parallel projects and a shared resources storehouse, and the enterprise’s operation only involves one kind of critical human resources. The supply of the critical human resource is limited, which cannot be obtained by hiring or any other ways during a certain period .when resource conflict among parallel projects occurs, we may allocate the human resource to multi-project according to project’s priorities .The allocation of non-critical independent human resources is not considered in this paper, which supposes that the independent resources that each project needs can be satisfied.Engineering projects usually need massive critical skilled human resources in some critical chain ,which cannot be substituted by the other kind of human resources .When the critical chains of projects at the same time during some period, there occur resource conflict and competition .The paper also supposes that the corresponding network planning of various projects have already been established ,and the peaks of each project’s resources demand have been optimized .The delay of the critical chain will affect the whole project’s duration time .3.2 Model HypothesesThe following hypotheses help us to establish a mathematical model:(1)The number of mutually independent projects involved in resourceallocation problem in multi-project is N. Each project is indicated withQ i,while i=1,2, … N.(2)The priority weights of multi-project have been determined ,which arerespectively w1,w 2…w n .(3) The total number of the critical human resources is R ,with r k standingfor each person ,while k=1,2, …,R(4) Δk i = ⎩⎨⎧others toprojectQ rcer humanresou i k 01(5) Resources capturing by several projects begins on time. t E i is theexpected duration time of project I that needs the critical resources tofinish some task after time t ,on the premise that the human resourcesdemand can be satisfied .tAi is the real duration time of project I thatneeds the critical resource to finish some task after time t .(6) According to the contract ,if the delay of the project happens the dailycost loss due to the delay is △c i for pro ject I .According to the project’simportance ,the delay of a project will not only cause the cost loss ,butwill also damage the prestige and status of the enterprise .(while thelatent cost is difficult to quantify ,it isn’t considered in this articletemporarily.)(7) From the hypothesis (5) ,we can know that after time t ,the time-gapbetween the real and expected duration time of project I that needs thecritical resources to finish some task is △t i ,( △t i =t A i -t E i ). For thereexists resources competition, the time –gap is necessarily a positivenumber.(8) According to hypotheses (6) and (7), the total cost loss of project I is C i(C i = △t i * △C i ).(9) The duration time of activities can be expressed by the workload ofactivities divided by the quantity of resources ,which can be indicatedwith following expression of t A i =ηi / R i * ,.In the expression , ηi refersto the workload of projects I during some period ,which is supposed tobe fixed and pre-determined by the project managers on project planningphase ; R i * refers to the number of the critical human resources beingallocated to projects I actually, with the equation Ri * =∑=Rk ki 1δ existing. Due to the resource competition the resourcedemands of projects with higherPriorities may be guarantee, while those projects with lower prioritiesmay not be fully guaranteed. In this situation, the decrease of theresource supply will lead to the increase of the duration time of activitiesand the project, while the workload is fixed.3.3 Optimization ModelBased on the above hypotheses, the resource allocation model inmulti-project environment can be established .Here, the optimizationmodel is :F i =min Z i = min∑∑==Ni i N i Ci 11ω =min i i Ni i N i c t ∆∆∑∑==11ω (2) =min ∑∑==N i i N i 11ω )E i R i ki i t - ⎝⎛∑=1δη i c ∆ 2F =min Z 2=min ()i t ∆=min )E i R i ki i t -⎝⎛∑=1δη (3) Where wj=max(wi) ,(N j i 3,2,1,=∀) (4)Subject to : 0∑∑==≤R k ki N i 11δ=R (5)The model is a multi-objective one .The two objective functions arerespectively to minimize the total cost loss ,which is to conform to theeconomic target ,and to shorten the time delay of the project with highestpriority .The first objective function can only optimize the apparenteconomic cost ;therefore the second objective function will help to makeup this limitation .For the project with highest priority ,time delay will damage not only the economic benefits ,but also the strategy and the prestige of the enterprise .Therefore we should guarantee that the most important project be finished on time or ahead of schedule .4.SOLUTION TO THE MULTI-OBJECTIVE MODEL USING GENETICALGORITHM4.1The multi-objective optimization problem is quite common .Generally ,eachobjective should be optimized in order to get the comprehensive objective optimized .Therefore the weight of each sub-objective should be considered .Reference [8] proposed an improved ant colony algorithm to solve this problem .Supposed that the weights of the two optimizing objectives are αand β ,where α+β=1 .Then the comprehensive goal is F* ,where F*=αF1+βF2.4.2The Principle of Genetic AlgorithmGenetic Algorithm roots from the concepts of natural selection and genetics .It’s a random search technique for global optimization in a complex search space .Because of the parallel nature and less restrictions ,it has the key features of great currency ,fast convergence and easy calculation .Meanwhile ,its search scope is not limited ,so it’s an effective method to solve the resource balancing problem ,as in [9].The main steps of GA in this paper are as follow:(1)EncodingAn integer string is short, direct and efficient .According to thecharacteristics of the model, the human resource can be assigned to be acode object .The string length equals to the total number of humanresources allocated.(2)Choosing the fitness functionThis paper choose the objective function as the foundation of fitnessfunction .To rate the values of the objective function ,the fitness of then-th individual is 1/n。

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 research in 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 watershortage 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 T aiwan 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 actualquantity of water consumed in a building to the average water-consu mption 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 ofwater 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 simplewater-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 watersystem 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 adopted in 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 intermediatewater 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 yielddifferent 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 T aiwan 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 basicevaluation on “Low environment impact”. Higher level is sues 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 envir onment 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 T aiwan.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 T aiwan, 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.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。

The GSHP has great potentials in energy reduction and in reducing CO2emissions to conventional HVAC systems. In China, energy shortage and environmental issues pose a seriouschallenge accompanied by rapid economic growth. GSHP has been spotlighted as both energy efficiency and environmental benefits. Generally, the initial investment for a GCHP system is higher than that of a conventional system. GCHP energy savings will offset the higher installing cost in future. However, there are many aspects affecting the actual amount of energy saved, such as climate, building load, ground heat exchanger, heat pump, control, etc. Recently, a lot of research on the energy performance of GCHP has been carried out. However, most of these previous research projects evaluated the performance of GCHP system based on a laboratory scale or a small capacity system. There is little data documenting the long-term performance of a large-sized GCHP. Evalution and research on real world installed GCHP will provide a more accurate understanding of the current technology’s performance.The paper presented that the energy performance evaluation of two types of GSHPs based on actual operational data. The two types of GSHPs were ground-coupled heat pump system (GCHPs) and groundwater heat pump system (GWHPs) which were,respectively, installed in two apartment buildings of Wuhan, China. In one year, we monitored various operating parameters, including the outdoor temperature, the flow rate, electrical consumption, and the water temperature. The coefficient of performance (COP) values of system and chiller were determined based on a series of measurements. During residential GCHP system operation, the heat injection rate into soil is larger than the heatextraction rate out of soil. The COP of chillers of the GCHPs decreased significantly during the heating season due to the lowering of ground soil temperature. The system power consumption exhibited a strong linear relationship with outdoor temperature in both seasons and this suggests that normalizing power consumption against degree-days is a highly practical index in energy analysis in resident buildings, especially in winter.Some research topics were studied on the two actual cases. An exergy analysis of a ground water heat pump system on the actual operation was conduced. The energy efficiency and exergy loss and efficiency in each of the components of the system are detemined forthe average measured parameters obtained from the monitored results of the hottest month and the coldest month. Inefficient facts are found out and increased energy efficiencies of two proposed improvement measures were estimated. Lower approachtemperature is effective energy saving. In addition to the energy analysis, a full exergy analysis helps to identify the components where inefficiencies occur. An economic analysis model forGWHP was established to calculate energy consumption and operating cost based on a baseline condition. Plate heat exchanger flow rate and groundwater flow rate were optimization parameters according to different water price of the groundwater:GWHP survey data shows the impact of water price on groundwater flow rate in design. The long-term energy performances of theGWHPs and the GCHPs were investigated and compared with conventional HVAC systems and other GSHPs on literature data. A performances model was established base on the two cases to constrast the predictedperformance with the actual performance.Based on superposition theorem of geothermal heat exchangers (GHE), a inverse model for GHE, G-functions interpolationapproach was proposed. Linear interpolation method was adopted to fit G-functions. The method presented here uses the Nelder and Mead simplex algorithm as part of a parameter estimation algorithm to estimate G-function. For verification of G-functions interpolation approach, anumerical experimentation had been conducted where synthetic load on GHE was established. The simulation results with error and no error, were inversely modeled by G-functions interpolation approach and DST calibrated approach. The actual dataset of a small sized and a large sized GSHPs were also used in inverse modeling to verify the results from the G-functions interpolation approach. The small sized GSHPs was from literature. The large sized vertical GSHPs was the monitored case in the paper. A detailed DST model of a GHE has been calibrated to monitored data. The secondyear predicted temperatures calculated by the two models were compared with the measured. The results show the two approaches are reliable and have good performance of error tolerance. The error of GHE water temperature calculated by G-functions interpolation approach was less than DST calibrated approaches. The data error inversely modeled was mainly from recorded day data. As a extension study of the G-functions interpolation model, degree-day G-functions approach was proposed. The model was based on degree-day prediction load and can be applied on the residential buildings. The standard deviation of GHE water temperature by degree-day G-functions approach was larger than DST calibrated approaches. The result shows the appropriateness of degree-day G-functions interpolation approach for the quantitative modeling of GHE.This paper shows that the research on actual performance according measured data and presents two inverse models:G-functions interpolation model, degree-day G-functions model approach, which provides new methods for GHE inverse modelingWith the sustainable development theory being put forward in recent years, people pay more and more attention to energy efficiency and environmental protection. The Ground Source Heat Pump(GSHP) air-conditioning system has been a kind of new technology to save energy and protect environment. This paper gives an overview of technology economy analysis on GSHPAir-conditioning System and optimization design of its ground heat exchanger, which provide helpful suggestion to engineers.First, this paper gives an overview of the history of GSHP system in China and foreign countries.

Keyword:Concrete crack prevention processing ForewordConcrete is formed by a sand and gravel aggregate,cement,water and other materials but mixed heterogeneous brittle materials.Because the concrete construction transform with oneself, control etc. a series problem, harden model of in the concrete existence numerous tiny hole, spirit cave and tiny crack, is exactly because these beginning start blemish of existence just make the concrete present one some not and all the characteristic of quality.The tiny crack is a kind of harmless crack and accept concrete heavy, impermeable and a little bit other use function not a creation to endanger.But after the concrete besubjected to lotus carry, difference in temperature etc. function, tiny crack would continuously of expand with connect, end formation we can see without the aid of instruments of macro view the crack be also the crack that the concrete often say in the engineering.Concrete building and Component all take sewer to make of, because of crack of existence and development usually make inner part of reinforcing bar etc. materialcreation decay, lower reinforced concrete material of loading ability, durable and impermeable ability, influence building of external appearance, service life, severity will threat arrive people's life and property safety.A lot of all of crash of engineerings is because of the unsteady development of the crack with the result that.Modern age science research with a great deal of of the concrete engineering practice certificate, in the concrete engineering crack problem is ineluctable, also acceptable in certainly of the scope just need to adopt valid of measure will it endanger degree control at certain of scope inside.Thereinforced concrete norm is also explicit provision:Some structure at place of dissimilarity under the condition allow existence certain the crack of width.But at under construction should as far as possible adopt a valid measure control crack creation, make the structure don't appear crack possibly or as far as possible decrease crack of amount and width, particularly want to as far as possible avoid harmful crack of emergence, insure engineering quality thus.Concrete crack creation of the reason be a lot of and have already transformed to cause of crack:Such as temperature variety, constringency, inflation, the asymmetry sink to sink etc. reason cause of crack;Have outside carry the crack that the function cause;Protected environment not appropriate the crack etc. caused with chemical effect.Want differentiation to treat in the actual engineering, work°out a problem according to the actual circumstance.In the concrete engineering the familiar crack and the prevention1.Shrinkage crack and preventionShrinkage crack much appear after the concrete protect be over of a period of time or concrete sprinkle to build to complete behind of around a week.In the cement syrup humidity of evaporate would creation Shrinkage, and this kind of constringency is can't negative.Shrinkage crack of the creation be main is because of concrete inside outside humidity evaporate degree dissimilarity but cause to transform dissimilarity of result:The concrete is subjected to exterior condition of influence, surface humidity loss lead quick, transform bigger, inner part degree of humidity variety smaller transform smaller, bigger surface Shrinkage transform to be subjected to concrete inner part control, creation more big pull should dint but creation crack.The relativehumidity is more low, cement syrup body Shrinkage more big, Shrinkage crack be more easy creation.Shrinkage crack is much surface parallel lines form or the net shallow thin crack, width many between 0.05-0.2 mm, the flat surface part much see in the big physical volume concrete and follow it more in thinner beam plank short to distribute.Shrinkage crackusually the impermeability of influence concrete, cause the durable of the rust eclipse influence concrete of reinforcing bar, under the function of the water pressure dint would creation the water power split crack influence concrete of loading dint etc..Concrete Shrinkage be main with water ash of the concrete ratio, the dosage of the composition, cement of cement, gather to anticipate of the dosage of the property and dosage, in addition etc. relevant.Main prevention measure:While being to choose to use the constringency quantity smaller cement, general low hot water mire and powder ash from stove cement in the adoption, lower the dosage of cement.Two is a concrete of Shrinkage be subjected to water ash ratio of influence more big, water ash ratio more big, Shrinkage more big, so in the concrete match the ratio the design should as far as possible control good water ash ratio of choose to use, the Chan add in the meantime accommodation of reduce water.Three is strict control concrete mix blend with under construction of match ratio, use of concrete water quantity absolute can't big in match ratio design give settle of use waterquantity.Four is the earlier period which strengthen concrete to protect, and appropriate extension protect of concrete time.Winter construction want to be appropriate extension concrete heat preservation to overlay time, and brushing protect to protect.Five is a constitution the accommodation is in the concrete structure of the constringency sew.2.Plastic shrinkage cracking and preventionPlastic shrinkage is the concrete is before condense, surface because of lose water quicker but creation of constringency.The Plastic shrinkage crack is general at dry heat or strong wind the weather appear, crack's much presenting in the center breadth, both ends of the thin and the length be different, with each other not coherent appearance.Shorter crack general long 20-30 cm, the longer crack can reach to a 2-3 m, breadth 1-5 mm.It creation of main reason is:The concrete is eventually almosthaving no strength or strength before the final setting very small, perhaps concrete just eventually final setting but strength very hour, be subjected toheat or compare strong wind dint of influence, the concrete surface lose water to lead quick, result in in the capillary creation bigger negative press but make a concrete physical volume sharply constringency, but at this time the strength of concrete again can't resist its constringency, therefore creation cracked.The influence concrete Plastic shrinkage of the main factors of crack to have water ash ratio, concrete of condense time, environment temperature, wind velocity, relative humidity...etc..Main prevention measure:One is choose to use dry compression value smaller higher silicate of the earlier period strength or common the portland cement.Two is strict the control water ash ratio, the Chan add to efficiently reduce water to increment the collapse of concrete fall a degree and with easy, decrease cement and water of dosage.Three is to sprinkle before building concrete, water basic level and template even to soak through.Four is in time to overlay the perhaps damp grass mat of the plastics thin film, hemp slice etc., keep concrete eventually beforethe final setting surface is moist, perhaps spray to protect etc. to carry on protect in the concrete surface.Five is in the heat and strong wind the weather to want to establish to hide sun and block breeze facilities, protect in time.3.Sink to sink crack and preventionThe creation which sink to sink crack is because of the structure foundation soil quality not and evenly, loose soft or return to fill soil dishonest or soak in water but result in the asymmetry sink to decline with the result that;Perhaps because of template just degree shortage, the template propped up to once be apart from big or prop up bottom loose move etc. to cause, especially at winter, the template prop up at jelly soil up, jelly the soil turn jelly empress creation asymmetry to sink to decline and cause concrete structure creation crack.This kind crack many is deep enter or pierce through sex crack, it alignment have something to do with sinking to sink a circumstance, general follow with ground perpendicular or present 30 °s-45 °Cape direction development, bigger sink tosink crack, usually have certain of wrong, crack width usually with sink to decline quantity direct proportion relation.Crack widthunder the influence of temperature variety smaller.The foundation after transform stability sink to sink crack also basic tend in stability.Main prevention measure:One is rightness loose soft soil, return to fill soil foundation a construction at the upper part structure front should carry on necessity of Hang solid with reinforce.Two is the strength that assurance template is enough and just degree, and prop up firm, and make the foundation be subjected to dint even.Three is keep concrete from sprinkle infusing the foundation in the process is soak by water.Four is time that template tore down to can't be too early, and want to notice to dismantle a mold order of sequence.Five is at jelly soil top take to establish template to notice to adopt certain of prevention measure.4.Temperature crack and preventionTemperature crack much the occurrence is in bigsurface or difference in temperature variety of the physical volume concrete compare the earth area of the concrete structure.Concrete after sprinkling to build, in the hardening the process, cement water turn a creation a great deal of of water turn hot, .(be the cement dosage is in the 350-550 kg/m 3, each sign square the rice concrete will release a calories of 17500-27500kJ and make concrete internal thus the temperature rise to reach to 70 ℃or so even higher)Because the physical volume of concrete be more big, a great deal of of water turn hot accumulate at the concrete inner part but not easy send forth, cause inner part the temperature hoick, but the concrete surface spread hot more quick, so formation inside outside of bigger difference in temperature, the bigger difference in temperature result in inner part and exterior hot the degree of the bulge or cooling dissimilarity, make concrete surface creation certain of pull should dint.When pull should dint exceed the anti- of concrete pull strength extreme limit, concrete surface meeting creation crack, this kind of crack much occurrence after the concrete under constructionperiod.In the concrete of under construction be difference in temperature variety more big, perhaps is a concrete to be subjected to assault of cold wave etc., will cause concrete surface the temperature sharply descend, but creation constringency, surface constringency of the concrete be subjected to inner part concrete of control, creation very big of pull should dint but creation crack, this kind篇三：建筑与环境设备工程外文翻译毕业论文（设计）题系部名称：专业班级：学生姓名：学指导教师：教师职称：外文翻译目：浅谈建筑环境与暖通空调能耗号：XX11014233 讲师

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。

Green ecological building1、The rise and practice of “green building”China is a country that resources are not very rich country, with the development of society and economy, the improvement of people's living standard, the insecurity of resource we have a red light, and actively promote ecological construction has become the inevitable trend of development. Ecological building "new concept appeared in the 60's of the last century.In 70 the outbreak of the oil crisis, to make people aware of sacrificing ecological environment difficult to continue high speed economic development, consumption of natural resources most building industry must take the road of sustainable development.90 in the last century, green building (Green Buildings) in western countries, and the establishment of an international organization, was made about index system of green ecological building, carry out a lot of activities. As in 1987 and 1988 respectively in Sweden was held in Stockholm the "healthy building" international academic conference.In 1992 June, the United Nations Conference on environment and development through the “21 century agenda "of the draft document.World Commission on environment and development put forward the concept of sustainable development as a new standard to Rio de Janeiro "Declaration". Sustainable development means to fully respect the environment and the use of natural resources to implement conservation, including saving energy, minerals, water, land, protection of ocean and atmosphere, and the protection of biological diversity.Most countries in the world have accepted the idea.The last century, introduced to China in the late 1990s the concept of green building. In 1994, China published China's Agenda 21, the same time start a major national scientific and industrial engineering - in 2000 a well-off urban and rural residential technology industry works ". Published in 1996 the People's Republic of China Human Settlements Development Report put forward higher requirements and assurance measures to further improve and enhance the quality of living environment. Green building rating system in recent years are also stepping up implementation. Compared with foreign countries, China's key technology research and development in the individual ecological needs further deepening. Such as in building energy efficiency,compared with countries with similar climate, the building energy consumption of the heating region in China about three times: in the green building design, natural ventilation and renewable energy use, green building materials, indoor environment, resource reuse technology, green and configuration technology research required to accelerate the applied research. Based on the results of theoretical studies of green building, Beijing, Shanghai, Guangzhou and other economically developed regions with local characteristics to actively carry out the integration of research and practical application of the key technologies of the green building system. For example: more than the North Lu spring Ecological Area, Beijing Tiptop International Apartment Guangzhou, Grand View Park, Shanghai million colones Run Park. "Shanghai World Expo ecological" and "Beijing Green Olympics" as the background of the "Shanghai ecology demonstration building and Tsinghua ultra-low power demonstration building" green building demonstration projects have been completed and open to the domestic and international, to become China's green building technology show education base and follow-up research and development platform.2、Definition and characteristics of green building and technical requirementsGreen building as the representative of the Audubon Society headquarters in the United States, it is the most energy-efficient buildings in Manhattan, New York, is considered to be a new milestone in the history of construction of environmental protection. What is a green ecological building. At present, the view that it must be a saving construction. Reflected in the health, water, land, energy conservation, pollution control, recycling. Architectural aesthetics in the development process as the goal, the principle of a virtuous cycle for the protection of ecosystems, green economy, green social connotation, green technology to support new construction, green environment set up as a symbol. It reflects the natural design concept and architectural unity and concord, it is the ultimate goal and natural balance in the whole process of its life cycle, so that to reduce the consumption of resources, protection of ecosystems, human health, comfort health, is the building of a sustainable development model.Green building features summed up in the following points: First, as far as possible to conserve resources and non-renewable energy consumption,reflecting the 3R principle Freud, Reduce, Recycle), ie, re-use, conservation, recycling. Second, protection of ecosystems, and to adhere to the harmonious coexistence of man and nature. Mainly reflected in the selection and use of low environmental impact materials; in the construction process, minimizing the impact of on-site ecosystem; does not affect the entire residential area of the local human environment. Third, the health of people harmless, makes people feel comfortable and healthy, we must make use of green building materials or clean, non-toxic building materials. The design must reflect the user-friendly design, construction, noise, contaminants, wastes must be prevented adverse effects on the human body.According to domestic and international research on green eco-residential area, roughly in the following areas. First, the energy system. Electricity, gas, coal energy into the cell under normal circumstances. To optimize the analysis of these energy sources, using the best solution on the residential building envelope and heating, air-conditioning system for energy-saving design, building energy efficiency to reach at least 50% or more. Wherever conditions permit, to encourage the adoption of new energy and green energy (solar, wind, geothermal energy, tidal energy and other renewable resources). Second, the water environment systems. Water system for the district to consider the issue of water quality and quantity. The outdoor system to set up gray water, rainwater and other treatment in water reuse systems, rainwater harvesting systems, gray water recycling system. Landscape water waterscape projects to be designed and included in the water system is taken into account. The district water supply facilities should be energy and water conservation type, the implementation of water-saving appliances. Gas environmental systems. The district system of the gas environment, including indoor and outdoor. Outdoor air quality met Grade II standard; live indoor achieve natural ventilation to maximize the use of green building materials, bathroom with ventilation equipment, kitchen equipped with flue gas concentrated drainage systems, indoor air quality standards to ensure the health of residents . Fourth, sound environmental systems. Acoustic environment of the district system, including outdoor, indoor, and the district outside noise deadening measures. Daytime noise of the outdoor acoustic environment system should be less than 50 dB at night less than 40 dB; architectural design to be used in noise reduction measures to meet the indoor sound environment system: Day 1 Secretary noise is less than 35 dB, less than 30 dB at night. Light environment system. The light environment of thedistrict general emphasis to meet the sunshine requirements, and interior to maximize the use of natural light. , To promote new energy green lighting in outdoor public places, use of energy-saving lamps. 6 is a thermal environment system. Residential thermal environment of the system to meet the thermal comfort requirements of the residents, building energy efficiency requirements, and environmental requirements. 7 is a green system. In the building next to the tree planting, turf green, can play a wind, insulation, dust and landscaping effect; can achieve energy saving, air purification, the purpose of maintaining the ecological balance. Eighth, waste management and disposal systems. Using different methods of disposal of solid waste management, sound processing and comprehensive utilization of physical chemistry, solidification and high temperature incineration in the country. The management side, to reform the management mechanism, the establishment of supervision and law enforcement, do a good job of publicity and education, the establishment of the garbage fee system. Nine is a green building material systems. Green Building Materials to adopt cleaner production technologies, use less natural resources and energy, without being poisoned by heavy use of solid waste produced by industrial or urban, non-polluting, non-radioactive, conducive to environmental protection and human health, building materials.3、to accelerate our country green ecological residential quarter sustainable healthy development several suggestions3.1 To raise awareness of the importance of the development of green eco-residential areaAlthough China has a vast territory, abundant supplies, but because of the large population, coupled with stepped forward a few years without restraint the development, production, resource severe shortage; arable land, forest area, water, etc. substantial reduction in environmental pollutionvery serious. Therefore, from the thought, conscience, on the implementation of green eco-residential area should be increased and sustainable human development is closely related to the height, which is the primary task.3.2 The Government must introduce a series of industrial policies to support green eco-construction of the residential areaGreen ecological residential area initial investment is relatively high, and return slowly. If there are no taxes, grants or restrictions on the use of certainareas of materials substantially implemented in the country will have a certain degree of difficulty. Although the Ministry of Construction launched in April 2001, "green eco-construction of residential quarters points with the Technical Guidelines", pointed out the system in the green eco-residential district development indicators and criteria. However, the support given to a series of links in the construction of a planning permit, the issuance of construction permits is not enough. Only given them preferential treatment in order to enable more developers will invest in this emerging industry3.3 vigorously develop new technologies, new materialsGreen ecological residential area constitutes a synthesis of form, materials, appearance and technology. Its implementation to rely on a large number of relevant technical and material support. Such as foreign tiles can absorb pollutants; use of waste paper, paper residue created by the fire insulation materials; inhibit groundwater dry, protection of ecological environment in the role of concrete. These can be used as our development of new materials, new technologies draw.3.4 optimization of building energy efficiency. Development of green energyFrom the regional planning begins to consider to irrigate the problem.The key should catch good the following: first, energy saving building energy saving is a system, must from the planning and architectural design. For example, a reasonable choice of building orientation, control building shape coefficient of residential buildings and energy saving, pay attention to the relationship between the eaves, attention, cornice, sun visor, curtain structure for regulating sunlight, energy saving effect. Second, take effective measures, improve the thermal performance of retaining structure.Walls, doors and windows and roof of building envelope components, in the energy saving residential buildings occupy an important position. For example, the reasonable control of external window area, selection of heat transfer coefficient of small frame material and energy saving glass doors and windows, to increase the air tightness. Third, optimize the indoor heating system energy saving.Further to increase the heating system planning.The piece of the residential development should adopt the centralized heating, household metering mode, according to heat more contributions approach. Water supply and drainage and electrical systems shall be used for energy-saving equipment, such as energy-saving lamps, water-saving sanitary utensil. Fourth, make full use of green energy.Solar energy, biomass energy, ocean can gang,and geothermal energy, according to local resources, suit one's measures to local conditions to do a good job in the development of green energy planning, to play its great potential, such as solar energy, firedamp technology application obtained very good economic benefits and environmental benefits.。

So, what kind of building could be called eco-buildings?The concept of eco-building The so-called eco-building, according to the local natural environment, the use of the principle of ecology, building technology, science and other relevant subject knowledge, reasonably arrange and organize the relationship between buildings and other relevant factors in thefield and the environment form an organic combination ofoverall, and suitable for human dwelling. Ecological building must meet the following four points: first, to be coordinated with the surrounding environment, and has protective effects on the surrounding ecological environment; buildings must not be on the natural environment caused by pollution or destruction of buildings within the usercan better to enjoy nature and feel that conferred comfortable and pleasant;The interior design should try to return to nature, such as natural lighting,natural ventilation, use of solar energy, the ideal indoor green; Fourth, a variety of substances, the source within the building systems can be orderedcycle of conversion. To sum up is to achieve respect for the environment andreturn to nature Manifestations of ecological building.For the above definition, the present ecological architecture instance,manifestations of ecological building can be summarized as follows:2.1 building energy efficiencyView to the current architectural trend, low-power has become one of theimportant symbol of ecological building. The more common way to solar, wind, hydro, geothermal and other non-polluting energy, directly or throughtechnology transfer, building use form, to help the building to reduce energy consumption in lighting, ventilation, heating, etc..2.2 Building pollution prevention and controlPollution prevention and control of the building is an important part of the ecological construction. The core issue of environmental protection has always been one of the waste problem. People's concept of pollution controlto focus only on production, the life process in sewagmagradually turned to thebuilding from construction to operation andmaintenance of pollution control in the process.2.3 building re-use resourcesIn the entire world's energy consumption 50% in building construction,maintenance and use of consumption, so efficient use of resources,recycling and reduce the impact on the natural environment is the construction of resource use in ecological building to be rapidly improving link.In recent years, the emergence of ecological building materials ③ alleviatethis problem. First of all the main characteristics of saving resources and energy, followed by reducing environmental pollution, and finally the easyrecovery and recycling.Above discussion, a certain understanding of the ecological building.However, in order to further study the ecological building, is not enough torely on theoretical explanations, we need to analyze some examples, theory and practice, scientific research and understanding of ecological building.Below through the analysis and comparison of eco-building ideas and works of two masters (Thomas Herzog and Norman Foster), to further understanding and study of ecological architecture, and learn from themaster of thought and practice nutrition, explore the development and prospects of ecological construction in China.3.Thomas HerzogThomas Herzog is a perfect combination of technology and the arts, have a deep sense of mission at the same time on the ecology and environment of the German masters of architecture. His architectural works have a high level of technology, the essential meaning of his work lies in its ecological concern, notonly in his design, in the course of teaching, often exhibitions, a large number of works, in cooperation with other architects, he personally.He goes beyond the paradigm of modern architecture, and replaced with more eco-dumping Value orientation, and this orientation is bound to replace the old paradigm.3.1 Thomas Herzog, ecological building thoughtThomas Herzog rarely impose their own creative aspirations on the environment above, but to speculate and listen to the change process and the cycle of the ecological environment, the spirit of participation and cooperation to complete his work. His ecological building human and artificial matter to a natural and man-made natural cordial and harmonious situation. He always adhere to the principle of "from ecology to architecture, from technology to nature", he has eco sublimated into a mental and spiritual, and throughout his life, the building design process.Thomas Herzog's design is not considered an isolated internal and external form, on the contrary, his designs expanded to all aspects of the built environment and the relationship between the shape. In addition, he attaches great importance to work closely with other professionals to give greater freedom of architectural design activities through the development of new materials, new components, the new system and appropriate design tools, and ultimately to achieve the unity of the building and the natural environment coordination, as well as building its own sustainable development.Thomas Herzog in the architectural activities in addition to transportIn a variety of new materials, new components, the new system, has been updated in the research and development, more ecological, more reasonable materials, components andsystems. Such as: Peituo Kaposi external wall system, Fischer facade assembly system, solar grid system, and so on. Thomas Herzog is more concerned about the accuracy and efficiency of the buildings in harmony with their surroundings on the basis of their own energy-saving technologyThomas Herzog rarely own creative desire to impose. Architectural detail through carefully designed to improve resource and energy use efficiency, and reduce the cost of non-renewable resources to focus on the ecological environment.Thomas believes that architects should take advantage of the technology, because of high efficiency by using much less material than conventional practice materials to meet the same functional requirements. Of course, the introduction of new technology, they must be correct and proper. He also is very concerned about the flexibility of the design flexibility and architectural elements, not only emphasizes the flexibility of the building function, but also stressed that the flexibility and versatility of the architectural details.4.1 Norman Foster ecological building thinkingThe introduction of some of the ecological building exist today, and many architects of ecological building creative ideas, the vast majority focused on the use and adaptation of the material aspects of the construction of the external environment, such as solar energy, use of groundwater. These mostly belong to the understanding and use of building physics. Norman Foster building constructed as a space and place is established not merely meet the physical meaning of comfort should be a higher level of development to meet the cultural needs of the people, aesthetic orientation.His concern for the environment can be seen from the London Guildhall,and the transformation ofmodern technology and aesthetic orientation, theperfect combination of ecology and art is the perfect embodiment of a new aesthetic - Ecological Aesthetics.In addition to the above concerns, Norman Foster also paid great attention to micro-climate inside the building, he can focus on buildingmicro-climate specific grouped into three areas: First, a suitabletemperature and humidity (to meet the thermal comfort and health requirements); as far as possible, the most access to natural light (reducingthe energy consumption of artificial lighting); maximize natural ventilation (to reduce air conditioning energy consumption). However, under different climatic conditions different focus and approach of the above three elements. Thus, by the most efficient artificial means to achieve these objectives, or to achieve a balance between the various elements of Foster's relentless pursuit direction. In the two works in the south of France:Cary Center for the Arts and the Frederick Eustace place middle vocational schools is the full performance of his raw state climate concept. His design not only runs through the concept of ecological design, but also fully embodies the attention and respect of traditional cultural and geographical culture, compared with the past completely self-centered high-tech school ",this change is undoubtedly is very profound. It makes high-tech school "goes beyond a simple external style and step into a deeper realm. It can be said at this point he pointed out the direction for the future of high-techschool ", but also provided valuable experience for our commitment to eco-building architects in the field. 5 comparison of two mastersCan be seen through the eco-building ideas and works of two masters of architecture:5.1 in commonThe two masters of architecture in the field of ecological building made outstanding contributions to advocate with the new materials, new technologies, new systems and the appropriate design tools to complete their ecological construction works; emphasized in man and nature,architecture and nature harmony on the basis of up to create a morecomfortable working and living environment of mankind; for the same target from different aspects of making unremitting efforts to create a better environment to human beings, more spiritual and material wealth to leave our future generations .5.2 The differenceThomas Herzog in ecological architecture is mainly from the overall environment of staff (including the surrounding environment and buildingtheir own environment), and ecological building design and research; he has been emphasized from the human point of view of sustainable development, rather than short when the viewpoint of local issues; he not only cares about the past and present, he is more concerned about the future; he not only cares about the local area, but also with relevant regionaland even the future may impact the area; him more is the use of new technologies, building detail and from different disciplines collaborate to reach the building and the surrounding environment and the people and the natural harmony and symbiosis; he stressed that eco-construction is not anarchitectural form, but Ecology as an attitude and spirit throughout the design process and its life;more comprehensive and thorough research in ecological construction,ecological building design in the true sense of the truly harmony with their surroundings, and the surrounding eco-environmentalprotection, respect for the environment and return to nature.In ecological architecture, Norman Foster mainly to meet the cultural needs of the people's, aesthetic orientation to achieve the perfect combination ofecology and art; space creation through technical support and building internal and external body to respond to nature, integration of large natural.Ecological building design and works a greater degree of purpose to reach people yearning to nature and enjoy nature, the concept of micro-ecological climate to some extent, more in line with the ecological concept of "high-tech school" building. He is the use of ecological building epidermis and flexible, applicable to the internal space between the perfect combination to achieve the building itself and the coordination and integration of the surrounding environment.ConclusionEco-building ideas and works of two masters of architecture to there velation: eco-building is not a fashionable style and labels, not just a slogan. In such an economic and technological levels in China are not very advanced countries, all aspects of the construction industry should carry out ecological architectural thinking. In fact, there are some to adapt to thenatural environment, building products, such as: the cave of the northwest -pure green buildings, low energy consumption, low pollution, cool and pleasant environment, as well as a yurt in the steppes, the wind tower inXinjiang and so on. China's future construction should not blindly follow the example of all the foreign genre, this simply from the formal transfer, is not conducive to the formation of China's architectural features and is also astifle the creativity of the construction workers. As Thomas Herzog said:"We can not simply develop an ecology ofinternational standards in different countries have different conditions at different times, or should beaccording to national circumstances."China is a populous country, the state of the environment It is worrying, the relative lack of resources in China. It is not possible in a short time with the developed countries havethe technology, materials, systems, and theoretical support, which we need to proceed from reality, with the experience of other countries seeking eco-construction of roads suitable for China.At present, our research, practice and understanding of the ecological building there are many deficiencies, therefore, a targeted strategy is particularly necessary. Combined with our own situation, I believe that to try from the following points: First, strengthen the propaganda of ecologicalawareness and ecological building, in order to arouse the attention of the whole people, to cultivate ecological awareness; theb organization ofecological building research institutions, ecological building and its related areas of research and development, provide strong support for the practice of Chinese architects; outline of the college of Architecture Education to increase the proportion of eco-construction of knowledge and design courses; through the establishment of mechanisms to encourage and promote the development of eco-building . Many developed countries areor have already done so, and have achieved good results.ReferencesDiao Wenyi. Frankfurt Commercial Bank Building. Central building, 1999 (3):48-51. Xi Yu cheng.

国外著名建筑师的生态建筑思想比较[摘要]该文通过简要阐述生态建筑的概念和表现形式，以及对托马斯·赫尔佐格和诺曼·福斯特两位建筑大师的生态建筑思想和作品的比较，来学习和理解生态建筑，最后希望借助两位大师的突出成就来引起我国建筑师对生态建筑的重视和思考。

关键词:托马斯·赫尔佐格诺曼-福斯特生态建筑生态建筑的表现形式生态建筑思想生态美学目前，随着人们对防治环境污染和保持生态平衡意识的不断增强，以及城市绿化的日益发展，创造低能耗的、可持续发展的生态建筑环境这个崭新的建筑研究方向，越来越受到重视和推崇。

那么，什么样的建筑可称之为生态建筑呢?生态建筑是将建筑作为一个生态系统，其内部各种物质能源有序的循环使用，因而获得高效率、低能耗、少污染的建筑环境，并与自然相平衡，以此达到与自然的和谐共生。

本文对同样在生态建筑方面有突出贡献的两位国外建筑师(托马斯·赫尔佐格&诺曼·福斯特)进行分析和比较，希望能进一步达对生态建筑的认识和理解。

1 生态建筑的概念所谓生态建筑，就是根据当地自然生态环境，运用生态学、建筑技术科学的原理和其他相关学科知识，合理地安排并组织建筑与其他领域相关因素之间的关系，使其与环境形成一个有机结合的整体，且适合人类的栖居。

生态建筑必须满足以下四点：第一，必须与周围环境协调，并且对周围生态环境起到保护作用；第二，建筑物本身绝不可对自然环境造成污染或破坏，建筑物内部的使用者能较好地享受大自然并感受到其赋予的舒适和愉快；第三．室内设计应尽量回归自然，如天然采光、自然通风、利用太阳能、理想的室内绿化等；第四，各种物质、源在建筑系统内可以有序的循环转换。

归纳起来也就是要做到尊重环境和回归自然。

2生态建筑的表现形式针对上述定义，结合目前国内外生态建筑实例，可将生态建筑的表现形式归纳为以下几点：2．1建筑节能以目前的建筑态势来看，低能耗已经成为生态建筑的重要标志之一。

较为常见的方式有太阳能、风能、水能、地热能等无污染能源，直接或通过技术转换成为可被建筑利用的形式，帮助建筑在采光、通风、采暖等方面降低能耗。

2．2建筑污染防治建筑的污染防治是生态建筑的重要一环。

三废问题一直以来都是环境保护的核心问题之一。

人们的治污观念也从只注重生产、生活过程中排污的治理，逐渐转向了建筑从建设到营运、维护过程中的污染治理。

2．3建筑资源再利用在整个世界的能源消耗中有50％是在建筑的建造、维护和使用中所消耗的，所以对资源的高效利用、循环利用和降低对自然环境的影响是建筑资源利用在生态建筑这一领域中有待迅速提高的一个环节。

近年来，生态建筑材料③的出现缓解了这一问题。

其主要特征首先是节约资源和能源，其次是减少环境污染，最后是易于回收和循环利用。

通过以上的论述，对生态建筑有了一定的了解。

然而要进一步研究生态建筑，光靠理论阐述是不够的，我们必须去分析一些实例，理论与实践相结合，科学地研究和理解生态建筑。

下文通过对两位大师(托马斯·赫尔佐格和诺曼·福斯特)的生态建筑思想和作品的分析和比较，来更进一步地认识和研究生态建筑，从大师的思想与实践中汲取营养，探讨生态建筑在我国的发展与前景。

3托马斯·赫尔佐格(Thomas HerZoq)托马斯·赫尔佐格是一位将技术和艺术完美结合，同时对生态、环境等负有深深使命感的德国建筑大师。

他的建筑作品具有很高的工艺技术水平，他工作的本质意义在于其对生态的关注，这不仅体现在他的设计中，在教学当中、在经常举办的展览中、在大量的著作中、在与其他建筑师进行的合作当中，他都身体力行。

他超越了现代建筑的范式，并代之以更具生态倾向的价值取向，而这种取向必然取代旧的范式。

3．1 托马斯·赫尔佐格的生态建筑思想托马斯·赫尔佐格很少把自己的创作愿望强加于环境之上，而是推测和听从生态环境的变化过程和循环，本着参与及合作的精神去完成他的工作。

他的生态建筑思想是将人类和所有的人工制造物达到一个自然和人造自然的亲切和睦的境地。

他始终坚持“从生态到建筑，从技术到自然”的原则，他已经把生态升华成一种思想和精神，并以此贯穿他一生的建筑设计过程。

托马斯·赫尔佐格的设计不仅仅考虑一个孤立的内部工作和外在形式，相反，他的设计扩大到对影响建筑环境的所有方面及相互关系的塑造。

另外，他十分注重和其他各方面专业人士的紧密合作，通过对新材料、新构件、新系统和合适的设计工具的发展给予建筑设计活动更大的自由，并最终达到建筑与自然环境的统一协调，以及建筑自身的可持续发展。

托马斯·赫尔佐格在从事建筑设计活动中除了运用各种新材料、新构件、新系统之外，也一直在研究和开发更新、更生态、更合理的材料、构件和系统。

如：佩托卡波那外墙体系、菲舍尔立面组装系统、日光栅格系统等。

托马斯·赫尔佐格更关注的是建筑物在与周围环境协调基础上自身的节能程度、技术的精确性和高效托马斯·赫尔佐格很少把自己的创作愿望强加于性。

通过精心设计的建筑细部提高资源和能源的利用效率，减少不可再生资源的耗费，来达到对生态环境的关注。

托马斯认为，建筑师应该利用高效率的技术，因为可以通过采用比常规做法少得多的物质材料，满足同样的功能要求。

当然，采用新技术的前提是它们必须是正确、恰当的。

他同时非常关注设计的灵活性和建筑元素的灵活性，不仅强调建筑功能的灵活性，还强调建筑细部的灵活性和多功能性。

4．1诺曼·福斯特的生态建筑思想在现今存在的一些对生态建筑的介绍以及许多建筑师对生态建筑的创作思路上，绝大多数集中在对建筑外部环境的物质层面的利用和适应上，如太阳能、地下水的利用等等。

这些大都属于建筑物理方面的理解和运用。

而诺曼·福斯特则认为建筑作为空间的建构和场所的确立不应仅仅停留在满足人的物理意义的舒适度上，而应向更高的层次上发展，以满足人的文化需求、审美取向等。

从他的伦敦市政厅可以看出他对环境的关注以及对现代技术利用和审美取向的转变，其生态与艺术的完美结合是一种新的美学——生态美学的完美体现。

诺曼·福斯特除了以上关注点外还十分注重建筑物内部的微观气候，他对建筑微观气候的关注可以具体归纳为三方面：一是适宜的室内温度和湿度(满足人体热舒适及健康的要求)；二是尽可能最多地获得自然采光(减少人工照明的能耗)；三是最大限度地获得自然通风(减少空调能耗)。

但在不同气候条件下对以上三要素的侧重点和处理方式又有所不同。

因此，通过最高效的人工技术手段来实现以上目标或达到各要素之间的平衡就成为福斯特不懈追求的方向。

他在法国南部的两个作品：卡里艺术中心和弗雷尤斯地方中等职业中学就是对他生的态气候观的充分表现。

他的设计中不仅贯穿着生态设计的理念，同时也充分体现了对传统文脉和地域文化的关注和尊重，与过去的完全以自我为中心的“高技派”相比，这一转变无疑是十分深刻的。

它使得“高技派”超越了一种简单的外在风格而步入更深层次的境界。

在这一点上可以说他为“高技派”的未来指明了方向，同时也为我国致力于生态建筑领域的建筑师提供了宝贵的经验。

5两位大师的对比通过以上两位建筑大师的生态建筑思想和作品可以看出：5．1共同点两位建筑大师都在生态建筑领域做出了突出的贡献，都提倡借助新材料、新技术、新系统和合适的设计工具来完成他们的生态建筑作品；都强调在人与自然、建筑与自然和谐共生的基础上去为人类创造更为舒适的工作和生活环境；都在为同一目标从不同层面做着不懈的努力，给人类创造美好的环境，给子孙后代留下更多的精神和物质财富。

5．2不同点托马斯·赫尔佐格在生态建筑方面主要是从整体环境人手(包括周围环境和建筑物自身环境)，去进行生态建筑的设计和研究；他一直强调要从人类持续发展的角度，而非短时、局部的视点看问题；他不仅关心过去和现在，他更关心未来；他不仅关心本地区域，而且关心相关区域甚至将来可能会产生影响的区域；他更多的是借助与新技术、建筑细部以及不同学科的协作来达到建筑物和周围环境以及人与自然的和谐与共生；他所强调的生态建筑不是一种建筑形式，而是将生态作为一种态度和精神贯穿于他的设计过程及其一生；他在生态建筑方面的研究更加全面和彻底，是真正意义上的生态建筑设计，真正做到了与周围环境协调，并且对周围生态环境起到保护作用，尊重环境和回归自然。

诺曼·福斯特在生态建筑方面主要是以满足人的文化需求，审美取向来达到生态与艺术的完美结合；通过技术支持以及建筑物内部的空间创作和外部形体来回应大自然、融合大自然。

他的生态建筑设计和作品更大程度的是达到人对大自然的向往和享受大自然的目的，他的微观生态气候观在一定程度上更加符合“高技派”建筑的生态观。

他是运用生态的建筑表皮和灵活、适用的内部空间两者的完美结合来达到建筑物自身与周围环境的协调和融合。

结语两位建筑大师的生态建筑思想和作品给我们以启示：生态建筑不是一种时髦的风格和标签，也不是一个口号。

在中国这样一个经济和技术水平都不十分先进的国家里，建筑业的各个环节更应该贯彻的是生态建筑思想。

其实，中国也不乏适应自然环境的建筑精品，如：西北的窑洞——纯粹的绿色建筑，低能耗、低污染、冬暖夏凉、环境宜人，还有大草原上的毡房、新疆的风塔等等。

中国的未来建筑不应再盲目地效仿外国的种种风格流派，这种单纯从形式上的移植，不利于中国自身建筑特色的形成，对于建筑工作者的创造性也是一种扼杀。

正如托马斯·赫尔佐格所说：“不能简单地制定一个生态的国际标准。

不同的国家在不同的时期会有不同的条件，还是应该根据国情去定。

”我国是一个人口大国，环境状况令人堪忧，中国的资源相对匮乏。

因此，我们不可能在短时间内拥有发达国家所具有的技术、材料、系统以及理论支持，这就需要我们从实际出发，借助国外的经验寻求适合中国国情的生态建筑道路。

目前，我国对生态建筑的研究、实践以及认识还存在着许多不足，因此，一些针对性的相关策略的研究显得尤为必要。

结合我国自身的情况，笔者认为可以从以下几点去尝试：一是加强生态意识及生态建筑的宣传，从而唤起全民的重视，培养生态意识；二是组织生态建筑科研机构，进行生态建筑及其相关领域的研究和开发，为中国建筑师的实践提供有力的支持；三在高校建筑学教育的大纲中增加生态建筑知识和设计课程的比重；四是通过建立机制来鼓励和推动生态建筑的发展。

许多发达国家正在或已经这样做了，并取得了很好的成绩。
