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 peoples 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 1718 million square meters, more than the sum of all the developed countries each year completed the construction area. With the gradual advance of building a well-off society, the rapid development of construction, building energy consumption growing rapidly and has become the worlds 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, Chinas 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 70300years for residential 815 times. Chinas large public building energy consumption per square meter in the 1020 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 countrys 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 peoples 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, Chinas vast territory, continental climate performance significantly: compared with other regions of the same latitude, the winter of the worlds coldest countries in the same latitude, the average January temperature Northeast than other regions of the same latitude average low 1520 , the Huang-Huai basin low 1015, south of the Yangtze low 610, 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 peoples 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 peoples 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 targetsChinas 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. Chinas carbon dioxide emissions have been accounted for second in the world, while building carbon dioxide emissions can be caused also accounted for using the countrys 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 countrys 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 peoples needs energy-efficient buildings.3The importance of strengthening public building energy efficiency designBuilding 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 siting Construction 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 environment After 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 exterior climate conditions, to save energy and improve the effect of indoor microclimate environment.(1)Energy-saving design for roof The roof is an important part of the building and the outdoor air in contact with the main energy saving measures: the use of sloping roof; Set roof insulation layer; If necessary, an additional roof insulation (insulated overhead roofing, water roofing, green roofs, etc.).(2)Energy-saving design for floor layer The 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 design According 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 detail Energy-saving design detail, the overall energy efficiency of the building is also very important. Should proceed with the following parts: thermal bridge, take a reliable insulation and the bridge measure; the 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; window around the walls should be insulated; doors, window frames and wall the gap between the insulation material should be used efficiently caulking; the 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; all-glass curtain wall, the gap walls, floor or between beams and walls should be filled with insulation material.3.2.2Rational design of building space Reasonable 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 materials An 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 Chinas 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”。加强建筑节能，尤其是公共建筑节能有利于从根本上促进能源资源节约和合理利用，缓解我国能源资源供应与经济社会发展的矛盾，提高人民群众生活质量。其中建筑节能设计也是一个很重要的环节。本文主要对公共建筑节能的的重要性以及如何在建筑设计中落实建筑节能进行了阐述,并提出了一些个人的建议。关键词：公共建筑 建筑节能 建筑节能设计 重要性1 引言我国是一个发展中大国，又是一个建筑大国，全国房屋总建筑面积已超过400多亿，每年新建房屋面积高达1718亿，超过所有发达国家每年建成建筑面积的总和。随着全面建设小康社会的逐步推进，建设事业迅猛发展，建筑能耗迅速增长，已成为世界第二大能源消耗国。而一些公共建筑经常被作为一个城市现代化的象征,但又由于其结构和用途的特殊性，公共建筑往往也是耗能大户,这类建筑的节能潜力亟待挖掘。2 加强建筑节能，尤其是公共建筑节能的重要性2.1 加强公共建筑节能是社会发展的需要随着经济社会的快速发展、科技技术和生活水平的不断提高，能源问题已成为世界各国普遍重视的问题之一。在全世界总的能源消耗中，有25%40%的能源消耗在建筑上。目前我国建筑总能耗约占社会能源消费总量中的27%，逐渐接近三成。尤其是近年来，随着欧陆风的盛行，许多大型公共建筑为“求洋、求新、求大”，追求外立面效果，大面积采用玻璃幕墙，冬天冷、夏天热，必须借助于空调调节室温，以至于这类建筑的空调能耗比一般建筑要高出3倍。据调查，目前我国有5亿左右的大型公共建筑，耗电量为70300年,为住宅的815倍。我国大型公建每平方米年耗电量是普通居民住宅的10至20倍，许多大型公建包括政府办公大楼、商业大厦在使用过程中，其供暖、空调、通风、照明等方面消耗的能量已占全国建筑总能耗的30%左右。由此可见，加强建筑节能，尤其是公共建筑节能势在必行。2.2 加强公共建筑节能是改善工作生活环境的需要随着全面建设小康社会的逐步推进，舒适的建筑热环境日益成为人们工作生活的需要。在发达国家，适宜的室温已成为一种基本需求。在我国，人们对于生活品质的要求也在逐年提高。同时我国幅员辽阔，大陆性气候表现明显：与同纬度其他地区相比，冬季我国是世界上同纬度最冷的国家，一月平均气温东北地区比同纬度其它地区平均要偏低1520，黄淮流域偏低1015，长江以南偏低610，华南沿海也偏低5；夏季则是世界上同纬度平均最暖的国家(沙漠除外)，七月平均气温东北比同纬度其它地区平均偏高4，华北偏高2.5，长江中下游偏高1.52。因此，冬冷夏热，长期困扰着国民。人民生活越是改善，越不堪忍受寒冬酷暑的折腾，冬季要供暖，夏季要降温，这都要消耗能源。初步调查发现，夏季空调制冷电耗是近年来民用用电逐年递增的主要因数。而公共建筑更是成为能耗的“黑洞”，公共建筑空调系统能耗占建筑物总能耗的比重也在逐年增加。从宏观上讲，只有实现了能源资源的节约和合理利用，才能满足人们对舒适的热环境的需要。由此可见，加强建筑节能，尤其是公共建筑节能刻不容缓。2.3 加强公共建筑节能是实现国家节能减排目标的需要中国“十一五”规划纲要提出，“十一五”期间单位国内生产总值能耗降低20%左右、主要污染物排放总量减少10%。“十二五”规划纲要又提出，“十二五”期间非化石能源占一次能源消费比重达到11.4%；单位国内生产总值能耗降低16%，单位国内生产总值二氧化碳降低17%；主要污染物排放总量显著减少，化学需氧量、二氧化硫排放分别减少8%，氨氮、氮氧化物排放分别减少10%。随着城镇化的迅速发展，供暖和空调建筑用能日益增加，向大气排放的污染物急剧增长。我国二氧化碳的排放量已占到世界第二位，而建筑用能造成的二氧化碳的排放量又占到全国总用能造成的二氧化碳的排放量的1/4。在一定时期内，这种状况依然存在，节能减排任重道远。2.4 加强公共建筑节能是建筑技术进步的需要一方面，随着国家对建筑节能要求的日益提高，墙体、门窗、屋顶、地面以及供暖、照明等建筑的基本组成部分都发生了巨大的变化。房屋建筑不再是砖石等几种传统材料的天下，多年来习用的材料和工艺做法可能不得不退出历史舞台。许多新的高效保温材料、密封材料、节能设备和保温管道等如雨后春笋般出现。另一方面，新的节能材料的出现也促使了营造技术的不断发展。建筑相关行业，如设计、施工等部门不得不调整技术结构，创造出更好的、满足人民群众需要的节能建筑。3 加强公共建筑节能设计的重要性建筑节能是整个建筑全寿命过程中每一个环节节能的总和。是指在
