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。
谈建筑节能的重要性及建筑的节能设计

谈建筑节能的重要性及建筑的节能设计摘要:低碳、节能已成为我国现在与未来建筑事业转型与升级的主要趋势,也是我国建筑设计在新时期背景下的主体。
为了解决我国当前能源消耗的严重问题与促进建筑节能行业的可持续发展,建筑设计人员必须要结合时代的发展需求做好建筑节能设计工作,以充分提高建筑节能功效,从而促进我国建筑事业的可持续发展。
关键词:建筑节能;重要性;节能设计1建筑节能的内容和重要性分析建筑节能主要包括三个方面的内容,一是建筑照明、二是空调降耗,三是采暖节能。
要注意的是,建筑设计在实行节能设计时一定要和建筑舒适性结合到一起,这样更能满足人们对建筑的居住要求。
对于房屋建筑来说,建筑节能的定义是指通过一系列设计措施,将建筑材料、建筑设备对能源的消耗量的进行降低,在保证建筑功能完善的同时,减少建筑建设、运行、改造过程中的能源利用率,尽可能的降低建筑在全寿命周期内对环境造成的破坏和污染。
从建筑节能的定义上看,建筑节能的根本作用是节约能源,减少环境污染和危害。
如果要分析建筑节能的最终意义,其主要包括以下几个方面:一,建筑行业发展越甚,建筑能耗量就越大,对环境、能源的危害也就越大,如果建筑行业要继续走可持续发展道路,就必须克服能源消耗过大问题,采用建筑节能设计方式,切实降低建筑能耗;二,建筑节能设计考虑进了建筑舒适性,这一做法既能减少建筑能源损耗,还能确保建筑的功能实用性,充分满足现代人对建筑居住空间舒适性的要求,可谓一举两得;三,建筑节能工作的开展能有效降低大气污染程度,还原城市生态;四,建筑节能与国民生活息息相关,在某种程度上,建筑节能还能带动房地产经济和国民经济发展。
2、建筑的节能设计措施2.1建筑选址所谓建筑选址,即指建筑物的施工建设场地选择。
选址的基本要求是结合当地气候、地形环境、土壤土质和水文条件等多个因素进行地址确定,确保建筑选址的准确性。
建筑节能设计所贯彻的选址理念是,既要满足建筑物的实用功能,能实现建筑物和环境的结合,又要为建筑节能创造条件,尽量不破坏城市的生态系统平衡。

外文翻译--浅谈加强公共建筑节能和节能设计的重要性中文3886字附录附录A 外文翻译Talking About The Importance Of Strengthening PublicBuilding Energy Efficiency And Energy Saving DesignAbstract:In recent years, with the rapid development of national economy and accelerating urbanization, China's building energy consumption accounts for the proportion of the community is also growing rapidly, increasing by one percentage point more than a year, of which, many large public buildings to "seek Yang, Innovation, and big" building energy consumption and become a "black hole." Strengthening building energy efficiency, especially in public buildings and promoting energy efficiency and the rational use of energy and resource conservation fundamentally ease the contradiction between supply of energy resources and economic and social development, improve people's quality of life. Building energy efficiency design which is also a very important part. This paper focuses on the importance of energy efficiency in public buildings and how the implementation of building energy efficiency in building design are described, and made some personal advice.Keywords:Public buildings Building energy efficiency Building energy efficiency design Importance1IntroductionOur country is a developing country, it is a big country building, housing a total construction area of the country has more than 400 million square meters of new housing area per year up to 17~18 million square meters, more than the sum of all the developed countries each year completed the construction area. Withthe gradual advance of building a well-off society, the rapid development of construction, building energy consumption growing rapidly and has become the world's second largest energy consumer. Some public buildings are often used as a symbol of the modern city, but due to the special nature of its structure and purpose, and often also public buildings energy-hungry, energy-saving potential of such buildings urgently mining. Second, strengthen the construction of energy-saving, especially the importance of energy efficiency in public buildings. 2Strengthen the construction of energy-saving, especially the importance of energy efficiency in public buildings2.1The need to strengthen the energy efficiency of public buildings and social developmentWith the rapid economic and social development, and constantly improve the living standards of technology and science and technology, energy problem has become one of the important countries in the world. The total energy consumption in the world, 25% to 40% of energy consumption in buildings. At present, China's total energy consumption building society accounts for the total energy consumption of 27%, gradually, refrain. Especially in recent years, with the European style of vogue, many large public buildings as "seeking ocean, Innovation, and big", the pursuit of facade effect, a large area with glass walls, winter cold, summer heat, must resort to air conditioning adjust the room temperature, so that the air conditioning energy consumption than the general construction of such buildings to be three times higher. According to the survey, China has about 500 million of large public buildings, power consumption 70~300⋅kW years for residential 8~15 times. China's large public building ⋅2h/menergy consumption per square meter in the 10~20 times that of ordinary residential buildings, public buildings, including many large energy government offices, commercial buildings in the course of its heating, air conditioning, ventilation, lighting and other aspects of consumption construction accounts for about 30% of the country's total energy consumption. Thus, strengthening building energy efficiency, especially in public building energy efficiency is imperative.2.2To enhance public building energy efficiency is needed to improve the working and living environmentWith the gradual advance of building a moderately prosperous society,comfortable thermal environment is increasingly becoming the need of people's work and life. In developed countries, the suitable temperature has become a basic needs. In China, people are gradually increased requirements for quality of life. Meanwhile, China's vast territory, continental climate performance significantly: compared with other regions of the same latitude, the winter of the world's coldest countries in the same latitude, the average January temperature Northeast than other regions of the same latitude average low 15~20 ℃, the Huang-Huai basin low 10~15℃, south of the Yangtze low 6~10℃, southern coastal also low 5℃; summer is on the same latitude in the world average warmest countries (except the desert), the average temperature in July northeast than other regions of the same latitude the average high 4℃, North high 2.5℃, the Yangtze River is high 1.5 ~ 2℃. Therefore, hot summer and cold winter, long plagued the nation. More to improve people's lives, the more unbearable winter heat toss, heating in winter to the summer to cool, which consumes energy. Initial investigation found that summer air conditioning power consumption is a major factor in recent years, increasing in civilian electricity. The energy consumption of public buildings is to become the "black hole", air-conditioning systems in public buildings energy consumption of buildings accounts for the proportion of total energy consumption is increasing year by year. From a macro perspective, only to achieve the conservation and rational use of energy resources in order to meet people's need for a comfortable thermal environment. Thus, strengthening building energy efficiency, especially in public buildings energy- delay.2.3Strengthen public building energy efficiency is to realize the need for national energy saving targetsChina's "Eleventh Five-Year Plan" proposed to reduce by about 20% during the "Eleventh Five-Year" energy consumption per unit of gross domestic product, the total discharge of major pollutants by 10%. "Twelve Five-Year" Plan also proposed that "five" period of non-fossil fuels in primary energy consumption to 11.4%; reduce energy consumption per unit of GDP by 16%, reduce carbon dioxide per unit of GDP by 17%; major significantly reduce pollutant emissions and chemical oxygen demand and sulfur dioxide emissions were reduced by 8%, ammonia, nitrogen oxide emissions were reduced by 10%. With the rapid development of urbanization, heating and air conditioning building energy increasing, the rapid growth of emissions of pollutants into theatmosphere. China's carbon dioxide emissions have been accounted for second in the world, while building carbon dioxide emissions can be caused also accounted for using the country's total emissions of carbon dioxide can cause 1/4. In a period of time, this situation still exists, energy saving long way to go.2.4The need to strengthen public building energy efficiency building technology advancesOn the one hand, increasing as the country's energy requirements of the building, a fundamental part of the walls, doors, windows, roofs, floors and heating, lighting and other buildings have undergone tremendous changes. Housing construction is no longer a world of several traditional masonry and other materials, learning materials and processes used in practice for many years may have to quit the stage of history. Sprung up many new efficient insulation materials, sealing materials, energy efficient equipment and insulation pipes. On the other hand, the emergence of new energy-saving materials also contributed to the continuous development and create technology. Construction-related industries, such as design, construction and other sectors have to adjust the technical structure, create better meet people's needs energy-efficient buildings. 3The importance of strengthening public building energy efficiency design Building energy efficiency is the sum of the whole life of the whole building process every step of energy. Refers to the building planning, design, new (renovation, expansion), transformation and use of the process, the implementation of building energy efficiency standards, using energy-saving technologies, processes, equipment, materials and products to improve building insulation and heating performance heating, air conditioning, refrigeration and heating system efficiency, strengthening building energy systems operation and management, use of renewable energy, to ensure the quality of indoor thermal environment, reduce the number of heating, air conditioning, refrigeration and heating, lighting, hot water supply energy consumption. Building energy efficiency design is a comprehensive building energy efficiency is a very important part, is to enhance energy efficiency in buildings first gate.3.1The overall energy-saving design and the external environment3.1.1Reasonable sitingConstruction site is mainly based on the factors of local climate, soil, water, topography and the surrounding environmental conditions, considering.Architectural design, both to make the building suitable microclimate maintained throughout its life cycle, while also achieve the harmony of architecture and nature.3.1.2Rational design of the external environmentAfter building address is determined, according to the needs of architectural features, the external environment through rational design, to improve the existing micro-climate, creating an enabling environment for building energy efficiency.3.1.3Reasonable planning and program designReasonable construction planning and program design can effectively adapt to the harsh micro- climate. It includes determining the amount of the overall body building, body building and construction portfolio size, construction and other aspects of sunshine and orientation. Like yurt circular plane, conical roofs can effectively adapt to the harsh prairie climate, serve to reduce building cooling area, resist sand effect. For most areas, the introduction of energy-efficient natural ventilation of the building is very important. On the layout, you can create different pressure through the sunny side and the shady side of the building, ventilation can be formed even in no wind. Forming a tunnel in the body design of the building, so that the natural wind in which the roundabout, get good ventilation, so as to achieve the purpose of energy conservation. Sunshine principles and towards the choice is to get enough sunlight in winter and avoid the dominant wind, summer can take advantage of natural ventilation and minimize solar radiation. However, the orientation towards the construction program and the design of the building is often constrained by social history, culture, topography, urban planning, roads, environmental conditions, in order to make towards the building while meeting the summer heat and winter insulation is often difficult. Therefore, only trade-offs between various factors, to find a balance, try to be reasonable.3.2Energy-saving design monomers3.2.1Energy-saving structural design of various parts of the buildingEnergy-efficient structural design of various parts of the building, mainly to meet the same building as a fundamental part of the function, to be further design aspects of the material through the various parts (roof, floors, walls, doors, windows, etc.), construction and so on. Make full use of the building exteriorclimate conditions, to save energy and improve the effect of indoor microclimate environment.(1)Energy-saving design for roofThe roof is an important part of the building and the outdoor air in contact with the main energy saving measures: ①the use of sloping roof; ②Set roof insulation layer; ③If necessary, an additional roof insulation (insulated overhead roofing, water roofing, green roofs, etc.).(2)Energy-saving design for floor layerThe main structure is the use of a hollow space, and the design of the floor to the ceiling shape. If the circulating water disposed therein, the summer can reduce the indoor temperature of cold water circulating in winter and hot water circulation heating.(3)Energy-saving design for building envelope wallIn addition to energy-saving design of the wall to adapt to climate conditions, good insulation, moisture, insulation and other measures, should be reflected in the special structure can improve the micro-climate conditions, such as cold regions of the sandwich wall design, passive solar house in various regenerative wall (water wall) design, the Baghdad area in order to adapt to local climatic conditions are hot and dry in the wall of the outlet design.(4)Energy-efficient doors and windows designAccording to statistics, in our existing buildings with high energy consumption, 40% of the energy is dissipated through the doors. Therefore, to solve the problem of energy-saving windows and doors is important.(5)Energy-efficient building envelope design detailEnergy-saving design detail, the overall energy efficiency of the building is also very important. Should proceed with the following parts: ①thermal bridge, take a reliable insulation and the "bridge" measure; ②the external walls and overhangs member attached to the wall components, such as balconies, rain cover, by the facades balcony railing, air conditioner outdoor unit shelf, with pilasters, bay windows, decorative lines, bridges and shall take off the heat insulation measures; ③window around the walls should be insulated; ④doors, window frames and wall the gap between the insulation material should be used efficiently caulking; ⑤the gap doors, window frames and plaster layers around, should adopt caulking sealant insulation materials and seal the interface ofdifferent materials to avoid cracking, impact doors, thermal performance windows; ⑥all-glass curtain wall, the gap walls, floor or between beams and walls should be filled with insulation material.3.2.2Rational design of building spaceReasonable space is designed in a fully meet the functional requirements of the building using the premise of reasonable architectural space delimited (delimited flat and vertical separator) to improve indoor insulation, ventilation, lighting and other micro-climatic conditions, to save energy.3.2.3Selection of energy-saving building materialsAn important aspect of the rational use of energy-saving building materials are also comprehensive building energy efficiency. Building materials should be selected to follow a healthy, efficient, economical, energy-saving principles. On the one hand, with the development of technology, a lot of new efficient materials continue to be developed and applied to architectural design to better achieve energy savings. Such as new insulation material, waterproof material used in walls, roofs, and achieve a better insulation moisture effects; new translucent insulating glass (such as Low-E glass, etc.) in windows applications, played a better aluminum with adjustable visor to shade the purpose; translucent insulation.4ConclusionIn recent years, a series of national regulations and local building energy efficiency standards were introduced, from government officials to the construction industry all employees, not just from the thought of the importance of energy efficiency in buildings have a certain visual recognition, and in particular work has also made certain achievements. However, with China's energy goals, there is a considerable gap, particularly public building energy efficiency, hesitant, far more than other civil difficulty saving. The reason for the policy on both factors, there are also reasons for funding. But I think the key is thinking and understanding is not in place, as long as the profound understanding of the importance of strengthening public building energy efficiency, we will be able to achieve our energy efficiency goals.From:Theoretical Studies Of Urban Construction浅谈加强公共建筑节能和节能设计的重要性摘要:近年来,随着国民经济的快速发展,城市化进程的不断加快,我国建筑能耗占社会能耗的比重也在快速增长,每年增加一个百分点以上,而其中,不少大型公共建筑为“求洋、求新、求大”而成为建筑能耗的“黑洞”。

据统计,我国建筑能耗的总量正逐年上升,在全社会总能耗中所占的比例已从上世纪70年代末的10%,上升到近年的30%,而这“30%”还仅仅是建筑物在建造和使用过程中消耗的能源比例,如果再加上建材生产过程中耗掉的能源(占全社会总能耗的16.7%),和建筑相关的能耗将占到社会总能耗的46.7%。
浅谈建筑节能设计的重要性

浅谈建筑节能设计的重要性1、引言近几年来,随着我国科学的进步与社会的发展,国民经济的发展呈现良好的势头,人们的生活水平也得到明显提高,建筑行业也取得了巨大的发展。
但是,在经济的快速发展的同时,我国资源环境问题也变得日益严峻,前阶段国民经济的发展和保护环境、节约资源的各项工作都不同步,造成对环境的极大破坏,资源利用不合理的情况极为常见,因而我国现阶段应该逐步开始重视节能措施的开发以及利用。
2、建筑节能设计的重要性在实际生活中,如果能够采用节能建筑的设计,将很大程度上降低能源的消耗程度,使能源缺乏的情况予以改善,从而使得经济能够得到更好的发展,同时促进我国经济的可持续发展也。
二是对周围环境保护。
生活的污染也是环境污染中的一种,其中建筑中的采暖就是生活中最大的污染源,也正因为如此,对建筑进行采暖和使用空调不仅将能源的消耗率面增多,还对环境造成了一定的污染。
而如果将节能方式应用到实际建筑设计中,不仅可以将生活污染给环境带来的压力减轻,使空气里面温室气体的含量得到降低,同时还可以提高住户的居住质量。
3、节能建筑设计的重点3.1墙面环保节能设计墙面容易对阳光发生反射作用,若反射作用明显,容易对外界造成光污染,危害他人健康,若没有反射又会有损建筑物的形象和美观。
因而,在节能建筑设计过程中应对墙面的立面形式,是用规则还是不规则;贴面装饰材料等方面就行精心地设计和配合,努力做到既不造成污染又能美观大方。
3.2墙体保温隔热的设计在墙体保温隔热的设计中,一方面要注意使用新型环保的保温隔热材料,如:保温棉,保温玻璃等的使用,可以大大降低室内温度散失率,达到保温隔热的长效节能效果。
另一方面要注意太阳辐射的隔离,这就需要设计人员在进行节能建筑设计时充分考虑的这一点,对墙体的建造采用合理的设计方法,对太阳光形成有效遮挡,以隔离太阳热,改善室内居住环境。
屋面、屋顶是建筑物中接受日照时间最长的构件。
3.3门窗节能的设计方法门窗是建筑物用于采光、通风的主要构件。

外文翻译ANALYSIS OF HVAC SYSTEM ENERGYCONSERVATIONIN BUILDINGSABSTRACTE conomic development and people's increasing demand for energy, but the nature of the energy is not inexhaustible. Environment and energy issues become increasingly acute, if no measures are taken, then the energy will limit the rapid economic development of the question.With the improvement of living standard, building energy consumption in the proportion of total energy consumption is increasing. In developed countries, building energy consumption accounts for 40% of total energy consumption of the community, while the country despite the low level of socio-economic development, but the building energy consumption has nearly 30% of total energy consumption, and still rising. Therefore, in western countries or in China, building energy consumption is affecting the socio-economic status of the overall development of the question. In building energy consumption, the energy consumption for HVAC systems has accounted for 30% of building energy consumption -50%, with the extensive application of HVAC, energy consumption for HVAC systems will further increase Great. HVAC systems are often coupled with high-quality electric energy, and our power and relatively tight in some areas, lack of energy supply and demand which is bound to lead to further intensification of contradictions. Therefore, energy-saving heating, higher professional requirements is inevitable across the board.KEYWORDS:energy-saving,HVAC1. Energy saving design measures should be takenRapid changes in science and technology today, area HVAC new technologies emerge, we can achieve a variety of ways of energy saving HVAC systems.1.1 Starting from the design, selecting, designing HVAC systems, so that the efficient state of the economy running.Design is a leading engineering, system design will directly affect its performance. The building load calculation is an important part of the design, a common problem is that the current design of short duration, many designers to save time, wrong use of the design manual for the design or preliminary design estimates of cold, heat load with the unit construction area of cold, heat load index, direct construction design stage as hot and cold load to determine the basis, often making the total load is too large, resulting in heating equipment, air conditioning is too large, higher initial investment, operating costs, increased energy consumption.1.2 using the new energy-saving air-conditioning and heating comfort and healthy mannerAffect human thermal comfort environment of many parameters, different environmental parameters can get the same effect of thermal comfort, but for different heat and moisture parameters of the environment of its energy consumption air conditioning system is not the same.1.3 Actual situation of a reasonable choice of cold and heat sources, seek to achieve diversification of cold and heat sourceWith the extensive application of HVAC systems on non-renewable energy consumption also rose sharply, while the broken part of the ecological environment are becoming increasingly intensified. How to choose a reasonable heating sources, has caused widespread concern of all parties.1.4 to enhance the use of hot and cold recycling of the work, to achieve maximum energyHVAC systems to improve energy efficiency is one of the ways to achieve energy-saving air-conditioning. Heat recovery system installed mainly through energy recovery, with the air from wind energy to deal with new, fresh air can reducethe energy required for processing, reducing the load, to save energy. In the choice of heat recovery, the should be integrated with the local climate Tiao Jian, Jing Ji situation, Gong Cheng actual situation of harmful exhaust gases of the situation in a variety of factors Deng integrated to determine the Xuanyong suitable heat recovery, so as to achieve Hua Jiao Shao's investment, recovery of more heat (cold) the amount of purpose.1.5 focus on development of renewable energy, and actively promoting new energyAs the air-conditioning systems used in high-grade, non-renewable energy resources and environmental problems caused by the increasingly prominent, have to develop some reasonable and effective renewable energy to ease the current tensions. To heat (cold) and solar and other renewable resources used in air conditioning and refrigeration, has certain advantages, but also clean and pollution-free. Ground Source Heat Pump is a use of shallow and deep earth energy, including soil, groundwater, surface water, seawater, sewage, etc. as a cold source in winter and summer heat is not only heating but also a new central air-conditioning system cooling.2. Saving design problemsAchieve energy-saving HVAC systems, now has a lot of mature conditions, but in practical applications there are some problems:2.1 The issue of public awareness of energy conservationThe past is not enough public understanding of energy, and on the air conditioning is also very one-sided view. For a comfort of air conditioning system or heating system, should the human body has a very good comfort. But the prevailing view now is: the colder the better air-conditioning, heating the more heat the better. This is obviously we seek the comfort of air conditioning is contrary to the view. In fact, this not only greatly increase the energy consumption of air conditioning heating, indoor and outdoor temperature and because of the increase, but also to the human body's adaptability to different environmental decline, lowering the body immunity. Therefore, we need to improve advocacy efforts to change public to the traditional understanding of air conditioning and heating, vigorous publicity andpromotion in accordance with building standards and the cold heat energy metering devices to collect tolls, raise public consciousness of energy.2.2 The design concept of the problemReasonable energy-saving design is a prerequisite. At present, some designers due to inadequate attention to design empirical value when applied blindly, resulting in the increase of the initial investment, energy consumption surprising, therefore recommended that the government functions and the energy-saving review body, to increase the monitoring of the HVAC air-conditioning energy saving efforts enhance staff awareness of energy conservation design, so that energy conservation is implemented.2.3 The promotion of new technologies issueNew technology in the HVAC system for energy conservation provides a new direction. Such as ground source heat pump systems, solar cooling and heating system, not only to achieve efficient use of renewable energy, and can bring significant economic benefits, is worth promoting. However, as with any new technology, these new technologies are often high in cost, and the geographical conditions of use have certain limitations, and technically there are still many areas for improvement to improve. Therefore, new energy-efficient technologies, we should be according to local conditions, sum up experience, and actively promote.3. ConclusionHVAC systems saving energy in the building occupies a very important position, should attract enough attention to the designer. Designers should be from a design point of view fully into account the high and strict compliance with energy standards energy saving ideas to run through all aspects of the construction sector. Energy-saving technologies and renewable energy recycling, the Government and other relevant departments should support and vigorously promoted. And the design, construction, supervision, quality supervision, municipal administration and other departments should cooperate closely and pay close attention to implementing a cold, heat metering devices to collect tolls, so people really get benefit from energy efficient building, energy-saving construction and non-heating energy efficientbuilding can not have the same charge standard. At the same time to raise public awareness of energy conservation, and vigorously promote the development of new energy-saving technologies to achieve sustainable development of society.References[1] "residential design standard" DBJ14-037-2006.[2] "Public Buildings Energy Efficiency Design Standards" DBJ14-036-2006.[3] "Technical Specification for radiant heating" JGJ142-2004.析暖通空调系统在建筑中的节能问题摘要经济的发展使人们对能源的需求不断增加,但是自然界的能源并不是取之不尽,用之不竭的。

High-rise building energy efficiency design好Pick to: early in the 20th century 70's, the concept of energy-saving building was officially proposed, the core of energy-saving building is to reduce energy consumption and enhance the architecture in building energy efficiency. But as China's sustained rapid economic growth, urbanization, high-rise building development has entered a residential areas, and become the mainstream of the construction industry. So, for the high-rise building energy saving design research, has become a hot issue of concern to the people.This paper discusses high-rise building energy-saving design summarized the present situation of and prospects for our country, the hope can high-rise building energy-saving design better and the international community, provide certain reference.Keywords: high-rise buildings; Energy-saving design; prospectprefaceEnergy is human survival and development of the basic conditions, along with the social progress and the rapid development of social economy, energy demand and supply, saving energy increasingly prominent contradiction between the current human face is one of the important tasks. But the energy conservation of the building is a basic world architecture development trend, as well as building a new growth point of science and technology.Along with the reform and opening-up and the rapid development of economy, China's high-rise buildings built in a high-rise building, the 1980s boom of the development is in the 1990s into the leap development stage. In high-rise building toward a higher, more strong direction at the same time, the energy saving design the general trend of development in human body to improve and health and improving the conditions of comfort, energy efficiency, rational utilization of resources, reduce greenhouse gas emissions, protecting environment for human survival. Therefore, high-rise building energy-saving design has become the world's architectural community, the concern of Chinese construction has become a hot issue.A, high-rise building energy-saving design in the application situationHigh-rise building efficiency is a complicated system engineering, from high-rise building ontology technology to high-level building materials products, high-rise building with equipment of thermal environment there are energy saving potential. Therefore, high-rise building energy saving design should be in guarantee its use function, construction quality and the premise of indoor environment, and adopts various effective energy saving technology and management measures.1, external wall thermal insulation energy-savingFor our country's existing high-rise building is concerned, its external form structural similarity is stronger, the characteristics of their energy consumption is evident, and the main embodied in the winter of heat preservation and heat insulation on summer energy-saving technology, which is beneficial in the popularization and promotion. In high-rise buildings of sino-foreign palisadestructure heat loss is bigger, peripheral protect structure wall and account for a large share. So high-rise building with wall body walling reform of energy-saving technology development is energy-saving design of high-rise building one of the most important aspects of exterior wall thermal insulation technology, development and energy saving material is the main energy saving high-rise buildings implementation. Energy-saving design mainly embodied in the following two aspects:The basic form of the building cannot change circumstances, high-rise building energy-saving design can use of external thermal insulation technology transformation pattern, building energy transformation can consider insulation energy-saving coating and lightweight composite insulation board techniques, such as using. At present, the efficient use of building insulation materials and composite wall practice in domestic popularize continuously, through adopting rock cotton, glass walls of cotton, polystyrene plastic, polyurethane foam plastics, polyethylene plastic new high efficiency heat insulation materials and reduce external heat transfer coefficient.In other functions of high-rise building the reconstructive requirement into consideration under the circumstances of less, energy efficiency design can use exterior insulation technology and exterior wall insulation energy-saving technologies combining transformation pattern. Reform, because its support structure, various technology using relatively independent space bigger, can consider to make the original wall insulation reinforcement again after the outsourcing, appropriate USES each type insulation energy-saving plank with insulation materials, and cooperate with insulation energy-saving door to wait the common use.2, roof insulation energy-savingRoofing is building periphery protect structure place suffers outdoor temperature the highest, area of high-rise building is larger also, as the importance of its energy-saving, particularly prominent therefore, roofing warm-keeping high-rise building for improving indoor temperature environment, save the overall energy consumption is very important.Our usual roofing heat insulating and energy-saving approach is low, the density of thermal conductivity small, bibulous rate is low, have a certain intensity of lightweight high efficiency heat preservation material set in waterproof layer and roof board, this kind of practice is between shop law. There are many high-rise building adopts the lightweight high strength, bibulous rate is very low extruded polystyrene board as thermal insulation material, using pour shop law, and good results were obtained. Pour shop law is set in the waterproof layer insulation layer, its advantage is due to heat preservation material protective effect, make waterproof materials from outdoor air temperature change and construction personnel for damage caused by one.when, greatly extend the waterproof material use fixed number of year, have certain energy-saving effect, but cost is higher.At present, our country USES light color slope roof energy saving design technology. It can effective drainage, prevent, roof leakage and could effectively heat insulation, energy saving. Deep dark roof only less than 30% of sunlight reflected, and nonmetal of light color roof at least 65% of sunlight reflected, reflectivity high roof about save 20 to 30 percent of energy consumption.Three, solar energy savingHigh-rise building energy efficiency design is another aspect of the new energy, development and utilization of solar energy as the one kind of renewable clean energy, is building a new energy ofone of the potential. Solar energy in in most regions of China has the good use conditions, the longest sunshine throughout the year up to 2 800 ~ 3 300 h, annual sunshine hours greater than 2 200 h (namely everyday average sunshine in more than 6 h) area, accounting for land area 2/3 above. Most of the heating area are distributed in long daylight area, these areas of 6hld sunshine hours in total appeared in more than 200 days, more can the d up to 300 d.Solar energy in China on high-rise buildings are mainly: ways of using passive solar heating, solar hot water, active solar energy heating and air conditioning, and solar power, etc. At present, with energy saving design research and the development of the high-rise building design of high-rise building layout, based on the characteristics and use features, additional sunshine with indoor heating equipment between combination of energy-saving design has won more and more people concern. It can make the high-rise buildings in the outdoor meteorological data change drastically circumstances, indoor temperature distribution more balanced, improve the indoor thermal environment and save energy.4 and reasonable use of various base terrain energy-savingThe low south in north high, should follow terrain north-facing slope to parallel is decorated high-rise buildings, such already can obtain sufficient sunshine and good ventilation, and positive view is broad, can reduce the sunshine spacing between high-rise buildings.The north slope in meteorological low on QianHouPai high-rise buildings, tonal the layer, avoid excessive widening sunshine spacing. Also try to use by the formation of the building bottom elevation of semi-closed space, as the auxiliary parking, storage space.In east and west on the slope, high-rise buildings should press vertical slope and follow the direction of slope decorate, der gewaltige hohenunterschied change its layers and height, maintain reasonable sunshine spacing, save land.On the flat terrain, should be decorated south, north to (PianJiao), can be appropriately it to comply with the wind, and can obtain good sunshine, was to reduce the distance, the best way to economical use of land.In marginal areas, according to the site, decorate tower, shape half-unit high-rise buildings; North of the base, decorate high-rise building, is also a good measure of land-saving.Second, high-rise building energy saving design development prospectsFacing the global energy of the growing tension, the countries of the world, especially euramerican developed country to energy saving technology has given full attention. In the past 30 years, countries in the high-rise building design and construction, new building materials, the development and application of the high-rise building energy conservation regulations formulated and implemented, high-rise building energy-saving attestation and management has done a lot of work. Not only save a huge amount of energy, gained considerable economic benefit, and improved the atmosphere environment, reduces the destruction of the ozone layer.But in China the high-rise buildings from energy-saving design work in the early 1990s just start. Therefore, we should do: first, energy aspect in design technology, actively adopt energy-saving building materials, new energy-saving wall body, the roof insulation technology, energy-saving door window insulation and airtight technology, increasing new and renewable energy such as solar energy and low thermal can in high-rise buildings, and further promote the application of different energy heat pump technology, products and recycling waste heat, waste heat technology; Secondly, in the high-rise building energy-saving design management, to strengthen high-level building energy efficiency standardization work, strictly enforce the energy-saving design ofhigh-rise building, high-rise building energy-saving design as high-rise building design meets the standards important assessment project; Again, in the high-rise building, the use of equipment products should adopt the energy-saving heating and air-conditioning equipment, and improve the energy efficiency of equipment operation, in order to achieve the purpose of energy-saving better. In short, the energy conservation of the building is one of the basic state policy of national development, high-rise building is the landmark buildings, so strong, pays special attention to energy conservation design of high-rise building, reasonable use and efficient use of energy resources, improving energy utilization, will promote national and local building energy saving and promote the whole society of building energy saving technology progress. China's high-rise building energy-saving road, should be in learning and borrowing abroad on the basis of successful practice, combined with actual situation in China, the establishment and the high-rise building energy-saving related key technology research and development efforts, accelerate to popularize the foreign advanced applicable energy-saving design technology, promote the development of the high-rise building energy-saving design. I believe in the near future, the joint effort of the high-rise building, our energy saving cause prosperous, bright future will be.References:[1] peak, under the guidance of the principle of sustainable architecture "senior commerce-residence building [J], journal of architectural technology university carried xian, 2003, 192-195 page.[2] Y angShan etc, the structure design of high-rise building [M], China construction science research institute, 1982.[3] li jun, "residential energy-saving design" [M], China architecture &building press, 2003.[4] HaoCheng seal, ZhuLi ZhuY an, concerning the residential building system, the development of thinking [J].j load of survey and design of construction technology and hebei province, January 2001.[5] LTK BREEAM: BREEAM for environmental rating for the Economies - Building homes, Establishment, true Warlord Garston, 2000.高层建筑节能设计摘要: 早在20世纪70年代,建筑节能的概念就被正式提出,建筑节能的核心是减少建筑能耗,提高建筑中的能源利用效率。

浅谈公共建筑节能设计的必要性摘要:公共设施节能设施的设计对于应对当前的能源危机是非常有意义的,在进行公共建筑的节能设计时,首先要根据具体情况做好规划和设计方案,然后进一步采用一些常用的节能设计措施,此外,政府的鼓励支持在这个过程中也是非常重要的。
本文对公共建筑节能设计的必要性进行了探讨。
关键词:公共建筑;节能设计;必要性;措施建筑节能是我国建筑业可持续发展的重大战略问题。
大力开展建筑节能的新技术、新产品、新工艺及先进适用成套技术的研发、攻关,同时加速建筑节能科技成果的转化和推广应用,为建筑节能的通用化、配套化、系统化提供技术支持,逐步推进节能建筑专业化、标准化的设计、施工已成为当务之急。
一、公共建筑节能设计的必要性通过相关数据查询了解到,公共建筑虽然在整体建筑中所占的面积比例并不大,但从能耗结构上来讲,其耗能是相当大的,另一方面,由于公共建筑有区别一般单户建筑的整体规模优势,如果采用合适的节能设计措施,公共建筑的节能潜力是非常大的。
从公共设施的能源结构上来看,空调和热水系统所消耗的能源量占整体能源消耗量的比重非常大,而当今关于空调与热水系统的节能技术已取得了较大的成就,因此,进行公共建筑的节能设计时,从空调和热水系统的节能入手是非常有效且有必要的。
此外,从我国整体的能源消耗结构上来看,建筑行业一直是一个耗能大户,所以,如果可以采取合适的节能设计来减少建筑行业的能源消耗,不仅可以节约能源,促进我国经济社会的可持续发展,而且可以优化能源配置结构,提高我国经济的运行效率,推动经济的发展。
二、公共建筑节能设计的具体措施1、合理的建筑体型设计在建筑设计中,应对建筑的体型以及建筑群体组合进行合理的设计,以适应四季不同的气候环境。
首先要控制体型系数,体型系数是建筑物外包表面积与其所包围的体积之比,体型系数过小,将影响建筑造型、平面布局、采光通风等;体型系数过大,则建筑物的外表面积大,导致外围护结构的传热损失大,直接影响建筑能耗。

中文3886字附录附录A 外文翻译Talking About The Importance Of Strengthening Public Building Energy Efficiency And Energy Saving DesignAbstract:In recent years, with the rapid development of national economy and accelerating urbanization, China's building energy consumption accounts for the proportion of the community is also growing rapidly, increasing by one percentage point more than a year, of which, many large public buildings to "seek Yang, Innovation, and big" building energy consumption and become a "black hole." Strengthening building energy efficiency, especially in public buildings and promoting energy efficiency and the rational use of energy and resource conservation fundamentally ease the contradiction between supply of energy resources and economic and social development, improve people's quality of life. Building energy efficiency design which is also a very important part. This paper focuses on the importance of energy efficiency in public buildings and how the implementation of building energy efficiency in building design are described, and made some personal advice.Keywords:Public buildings Building energy efficiency Building energy efficiency design Importance1IntroductionOur country is a developing country, it is a big country building, housing a total construction area of the country has more than 400 million square meters of new housing area per year up to 17~18 million square meters, more than the sum of all the developed countries each year completed the construction area. With the gradualadvance of building a well-off society, the rapid development of construction, building energy consumption growing rapidly and has become the world's second largest energy consumer. Some public buildings are often used as a symbol of the modern city, but due to the special nature of its structure and purpose, and often also public buildings energy-hungry, energy-saving potential of such buildings urgently mining. Second, strengthen the construction of energy-saving, especially the importance of energy efficiency in public buildings.2Strengthen the construction of energy-saving, especially the importance of energy efficiency in public buildings2.1The need to strengthen the energy efficiency of public buildings and social developmentWith the rapid economic and social development, and constantly improve the living standards of technology and science and technology, energy problem has become one of the important countries in the world. The total energy consumption in the world, 25% to 40% of energy consumption in buildings. At present, China's total energy consumption building society accounts for the total energy consumption of 27%, gradually, refrain. Especially in recent years, with the European style of vogue, many large public buildings as "seeking ocean, Innovation, and big", the pursuit of facade effect, a large area with glass walls, winter cold, summer heat, must resort to air conditioning adjust the room temperature, so that the air conditioning energy consumption than the general construction of such buildings to be three times higher. According to the survey, China has about 500 million of large public buildings, power consumption 70~300⋅⋅2kW years for residential 8~15 times. China's large publich/mbuilding energy consumption per square meter in the 10~20 times that of ordinary residential buildings, public buildings, including many large energy government offices, commercial buildings in the course of its heating, air conditioning, ventilation, lighting and other aspects of consumption construction accounts for about 30% of the country's total energy consumption. Thus, strengthening building energy efficiency, especially in public building energy efficiency is imperative.2.2To enhance public building energy efficiency is needed to improve the working and living environmentWith the gradual advance of building a moderately prosperous society, comfortable thermal environment is increasingly becoming the need of people's work and life. In developed countries, the suitable temperature has become a basic needs. InChina, people are gradually increased requirements for quality of life. Meanwhile, China's vast territory, continental climate performance significantly: compared with other regions of the same latitude, the winter of the world's coldest countries in the same latitude, the average January temperature Northeast than other regions of the same latitude average low 15~20 ℃, the Huang-Huai basin low 10~15℃, south of the Yangtze low 6~10℃, southern coastal also low 5℃; summer is on the same latitude in the world average warmest countries (except the desert), the average temperature in July northeast than other regions of the same latitude the average high 4℃, North high 2.5℃, the Yangtze River is high 1.5 ~ 2℃. Therefore, hot summer and cold winter, long plagued the nation. More to improve people's lives, the more unbearable winter heat toss, heating in winter to the summer to cool, which consumes energy. Initial investigation found that summer air conditioning power consumption is a major factor in recent years, increasing in civilian electricity. The energy consumption of public buildings is to become the "black hole", air-conditioning systems in public buildings energy consumption of buildings accounts for the proportion of total energy consumption is increasing year by year. From a macro perspective, only to achieve the conservation and rational use of energy resources in order to meet people's need for a comfortable thermal environment. Thus, strengthening building energy efficiency, especially in public buildings energy- delay.2.3Strengthen public building energy efficiency is to realize the need for national energy saving targetsChina's "Eleventh Five-Year Plan" proposed to reduce by about 20% during the "Eleventh Five-Year" energy consumption per unit of gross domestic product, the total discharge of major pollutants by 10%. "Twelve Five-Year" Plan also proposed that "five" period of non-fossil fuels in primary energy consumption to 11.4%; reduce energy consumption per unit of GDP by 16%, reduce carbon dioxide per unit of GDP by 17%; major significantly reduce pollutant emissions and chemical oxygen demand and sulfur dioxide emissions were reduced by 8%, ammonia, nitrogen oxide emissions were reduced by 10%. With the rapid development of urbanization, heating and air conditioning building energy increasing, the rapid growth of emissions of pollutants into the atmosphere. China's carbon dioxide emissions have been accounted for second in the world, while building carbon dioxide emissions can be caused also accounted for using the country's total emissions of carbon dioxide can cause 1/4. In a period of time, this situation still exists, energy saving long way to go.2.4The need to strengthen public building energy efficiency building technology advancesOn the one hand, increasing as the country's energy requirements of the building, a fundamental part of the walls, doors, windows, roofs, floors and heating, lighting and other buildings have undergone tremendous changes. Housing construction is no longer a world of several traditional masonry and other materials, learning materials and processes used in practice for many years may have to quit the stage of history. Sprung up many new efficient insulation materials, sealing materials, energy efficient equipment and insulation pipes. On the other hand, the emergence of new energy-saving materials also contributed to the continuous development and create technology. Construction-related industries, such as design, construction and other sectors have to adjust the technical structure, create better meet people's needs energy-efficient buildings.3The importance of strengthening public building energy efficiency design Building energy efficiency is the sum of the whole life of the whole building process every step of energy. Refers to the building planning, design, new (renovation, expansion), transformation and use of the process, the implementation of building energy efficiency standards, using energy-saving technologies, processes, equipment, materials and products to improve building insulation and heating performance heating, air conditioning, refrigeration and heating system efficiency, strengthening building energy systems operation and management, use of renewable energy, to ensure the quality of indoor thermal environment, reduce the number of heating, air conditioning, refrigeration and heating, lighting, hot water supply energy consumption. Building energy efficiency design is a comprehensive building energy efficiency is a very important part, is to enhance energy efficiency in buildings first gate.3.1The overall energy-saving design and the external environment3.1.1Reasonable sitingConstruction site is mainly based on the factors of local climate, soil, water, topography and the surrounding environmental conditions, considering. Architectural design, both to make the building suitable microclimate maintained throughout its life cycle, while also achieve the harmony of architecture and nature.3.1.2Rational design of the external environmentAfter building address is determined, according to the needs of architectural features, the external environment through rational design, to improve the existingmicro-climate, creating an enabling environment for building energy efficiency.3.1.3Reasonable planning and program designReasonable construction planning and program design can effectively adapt to the harsh micro-climate. It includes determining the amount of the overall body building, body building and construction portfolio size, construction and other aspects of sunshine and orientation. Like yurt circular plane, conical roofs can effectively adapt to the harsh prairie climate, serve to reduce building cooling area, resist sand effect. For most areas, the introduction of energy-efficient natural ventilation of the building is very important. On the layout, you can create different pressure through the sunny side and the shady side of the building, ventilation can be formed even in no wind. Forming a tunnel in the body design of the building, so that the natural wind in which the roundabout, get good ventilation, so as to achieve the purpose of energy conservation. Sunshine principles and towards the choice is to get enough sunlight in winter and avoid the dominant wind, summer can take advantage of natural ventilation and minimize solar radiation. However, the orientation towards the construction program and the design of the building is often constrained by social history, culture, topography, urban planning, roads, environmental conditions, in order to make towards the building while meeting the summer heat and winter insulation is often difficult. Therefore, only trade-offs between various factors, to find a balance, try to be reasonable.3.2Energy-saving design monomers3.2.1Energy-saving structural design of various parts of the buildingEnergy-efficient structural design of various parts of the building, mainly to meet the same building as a fundamental part of the function, to be further design aspects of the material through the various parts (roof, floors, walls, doors, windows, etc.), construction and so on. Make full use of the building exterior climate conditions, to save energy and improve the effect of indoor microclimate environment.(1)Energy-saving design for roofThe roof is an important part of the building and the outdoor air in contact with the main energy saving measures: ①the use of sloping roof; ①Set roof insulation layer;①If necessary, an additional roof insulation (insulated overhead roofing, water roofing, green roofs, etc.).(2)Energy-saving design for floor layerThe main structure is the use of a hollow space, and the design of the floor to theceiling shape. If the circulating water disposed therein, the summer can reduce the indoor temperature of cold water circulating in winter and hot water circulation heating.(3)Energy-saving design for building envelope wallIn addition to energy-saving design of the wall to adapt to climate conditions, good insulation, moisture, insulation and other measures, should be reflected in the special structure can improve the micro-climate conditions, such as cold regions of the sandwich wall design, passive solar house in various regenerative wall (water wall) design, the Baghdad area in order to adapt to local climatic conditions are hot and dry in the wall of the outlet design.(4)Energy-efficient doors and windows designAccording to statistics, in our existing buildings with high energy consumption, 40% of the energy is dissipated through the doors. Therefore, to solve the problem of energy-saving windows and doors is important.(5)Energy-efficient building envelope design detailEnergy-saving design detail, the overall energy efficiency of the building is also very important. Should proceed with the following parts: ①thermal bridge, take a reliable insulation and the "bridge" measure; ①the external walls and overhangs member attached to the wall components, such as balconies, rain cover, by the facades balcony railing, air conditioner outdoor unit shelf, with pilasters, bay windows, decorative lines, bridges and shall take off the heat insulation measures; ①window around the walls should be insulated; ①doors, window frames and wall the gap between the insulation material should be used efficiently caulking; ①the gap doors, window frames and plaster layers around, should adopt caulking sealant insulation materials and seal the interface of different materials to avoid cracking, impact doors, thermal performance windows; ①all-glass curtain wall, the gap walls, floor or between beams and walls should be filled with insulation material.3.2.2Rational design of building spaceReasonable space is designed in a fully meet the functional requirements of the building using the premise of reasonable architectural space delimited (delimited flat and vertical separator) to improve indoor insulation, ventilation, lighting and other micro-climatic conditions, to save energy.3.2.3Selection of energy-saving building materialsAn important aspect of the rational use of energy-saving building materials arealso comprehensive building energy efficiency. Building materials should be selected to follow a healthy, efficient, economical, energy-saving principles. On the one hand, with the development of technology, a lot of new efficient materials continue to be developed and applied to architectural design to better achieve energy savings. Such as new insulation material, waterproof material used in walls, roofs, and achieve a better insulation moisture effects; new translucent insulating glass (such as Low-E glass, etc.) in windows applications, played a better aluminum with adjustable visor to shade the purpose; translucent insulation.4ConclusionIn recent years, a series of national regulations and local building energy efficiency standards were introduced, from government officials to the construction industry all employees, not just from the thought of the importance of energy efficiency in buildings have a certain visual recognition, and in particular work has also made certain achievements. However, with China's energy goals, there is a considerable gap, particularly public building energy efficiency, hesitant, far more than other civil difficulty saving. The reason for the policy on both factors, there are also reasons for funding. But I think the key is thinking and understanding is not in place, as long as the profound understanding of the importance of strengthening public building energy efficiency, we will be able to achieve our energy efficiency goals.From:Theoretical Studies Of Urban Construction浅谈加强公共建筑节能和节能设计的重要性摘要:近年来,随着国民经济的快速发展,城市化进程的不断加快,我国建筑能耗占社会能耗的比重也在快速增长,每年增加一个百分点以上,而其中,不少大型公共建筑为“求洋、求新、求大”而成为建筑能耗的“黑洞”。
