建筑发挥着气候“调节器”的角色,通过利用和防御自然界各种气候因素,为人类创造出良好的室内气候条件。
我国是能源短缺的国家,但建筑能耗却是同等气候条件下发达国家的2 倍~3 倍。
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。
浅谈公共建筑节能设计的必要性摘要:本文从公共建筑节能设计的必要性、建筑与建筑热工设计,以及这公共建筑空调系统存在的问题与节能潜力三个方面对公共建筑节能设计的必要性进行阐述。
关键词:公共建筑;节能;设计;必要性一、前言随着社会的不断向前发展,人们对于建筑的节能设计越来越关注,为了提高人们对于建筑节能设计的关注和认知,本文对建筑节能设计的必要性以及相关的设计问题进行分析。
二、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。
三、建筑与建筑热工设计1.体形系数体形系数指的就是建筑物与室外大气接触的外表面积和与其所包围的体积之比值。
建筑物的体形变化对其采暖空调的能耗大小有着直接的影响。
通常情况下。
建筑物的单位面积多对应的室外面积越大,其外围护结构所产生的热损也就越大,因此,需要对建筑物的体形进行合理的确定,需要根据当地的气候条件、冬季和夏季的太阳辐射强度以及当地的季风情况等因素来确定,同时,应当对不同使用功能的建筑物进行分别对待,尽量减少建筑物房屋的外围面积,以此能够使一些体形不规则的建筑物也能够减少各种凹凸面所带来的热损。
2.围护结构热工设计(1)屋面的保温隔热设计性能的实现,需要在设计时遵循以下几点:a.在保温隔热材料的选择上,应当尽量选择热导系数小的保温材料,同时应当尽量选择密度小的材料,以此防止建筑物屋面的荷载过大.b.由于目前市面上所销售的保温隔热材料种类繁多,因此在进行选择时,应当根据建筑物的使用功能以及建筑物的屋面结构、建筑物所处的气候环境以及施工条件等因素进行全方面的综合考虑;c.根据建筑物的热工要求对建筑物的保温层厚度进行确定,同时根据保温隔热材料层的差别,对其排列次序进行合理的配置;d.建筑屋面内的保温隔热材料,一般不选择吸水率较高的材料,以此防止材料吸潮而影响热工性能。
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。

浅谈加强公共建筑节能和节能设计的重要性【文章摘要】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;重要性一、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多亿平方米,每年新建房屋面积高达17-18亿平方米,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。
二、加强建筑节能,尤其是公共建筑节能的重要性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m2左右的大型公共建筑,耗电量为70-300kwh/m2•年,为住宅的8-15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,其采暖、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。
浅谈建筑节能的重要性与建筑节能设计[摘要]建筑节能有利于从根本上促进能源资源节约和合理利用。
建筑节能是保证国民经济可持续发展的需要,必须从战略的高度充分认识节约能源、资源的重要性和紧迫性,然而从目前情况看,在对建筑节能的认识上,全社会仍存在很大的差距。
本文就节能环保建筑的构造设计进行了阐述,着重探讨建筑节能的重要性以及建筑节能设计。
[关键词]节能设计;环保建筑;可持续发展目前,我国在建筑上消耗的能源已经占到社会能源消耗总量的近28%,而且每年还在以 1%以上的速度增长,如此发展下去到2020 年,林立的高楼将可能占据中国能源消耗的 40%。
2008 年我国启动的10 大重点节能工程中预计节省的 2.2 亿吨能量中,建筑节能占1 亿吨,约占 45%。
建筑节能更具有其现实紧迫性与重要的战略意义,这说明建筑能耗的节约已经成为最大的节能项目,尤其在当前贯彻落实科学发展观、大力推进节能减排的形势下,抓好了建筑节能,也就抓住了节能工作的关键环节。
1节能能源利用原则能源资源分为可再生能源和不可再生能源,充分利用和发挥可再生能源是生态建筑对能源利用的方法之一。
我国的建筑中需要的能源主要是电能和热能,电能是市政线路供电,热能是采暖所需的暖气和做饭所需的煤气、天然气或石油液化气。
就我国的能源贮藏结构而言,煤炭、石油、天然气的大致可采年限分别为:320 年、16 年50 年,形势非常严峻。
并且这些能源在加工过程中产生大量的污染,一氧化碳、一氧化硫、氮氧化合物和粉尘悬浮物,严重污染了我们生存的环境。
因此,我们在建筑设计中,在节约使用不可再生资源的同时,应当重视新的能源利用方式,从可再生能源多想办法。
目前应用于生态建筑中的可再生能源有太阳能、风能、地热能等,其中以太阳能的利用最为广泛,技术也最为成熟。
2保温与隔热2.1 温度的变动朝南的大玻璃窗时常透入实际需要过量的太阳辐射热量,由于楼板、墙和顶棚以是缩小玻璃面积以减少进入建筑的太阳体种类很多,包括各种墙体墙面、磁砖地面向建筑除了25%楼板面积的采光玻璃窗面积要求以外,大都是一般及室内装修轻型结构等都吸收了大量的热量,然后再释放出来使室内的气温增高,形成房间之间的热流自然流通,造成一些太阳热能的无效使用。

I n 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 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 sitingConstruction site is mainly based on the factors of local climate, soil, water, topography and the surrounding environmental conditions, considering.

浅谈建筑节能的重要性及建筑的节能设计建筑能耗更是刻不容缓,而建筑节能是减少建筑能耗的有效方法,同时也是节约经济的方法。
因此,依据建筑规范对节能进行优化设计,充分利用我国现有的自然条件,在改善人们居住环境的同时,充分挖掘节能潜力,从而实现节约能源,减少能源消耗。
标签:建筑;节能设计;重要性;要点我国社会经济的飞速发展进步,使社会各个行业开始逐渐意识到节能设计的重要意义,并且节能设计在工程设计、施工、使用期间也有着极为广泛的应用。
建筑企业必须要将社会的可持续发展理念和当地的自然状况、风土人情紧密结合起来,这样所设计出的节能方案才是最高效可行的。
建筑工程节能设计除了会影响建筑企业的长远稳定发展,还会促进我国的城市化发展进程,这有助于我国的经济迈上一个新的台阶。
1 建筑节能的重要性建筑节能是发展国民经济的需要。
经济的发展依赖于能源的发展,需要能源提供动力。
1990~1995年第8个五年计划期间,我国生产总值平均每年增长12%,而一次商品能源平均每年增长才有3.16%。
这种能源生产的增长速度滞后于国内生产总值的增长速度,将严重影响我国的经济发展。
因此,能源短缺对我国经济的发展是一个根本性的制约因素。
我们要发展国民经济,就非依赖于节能不可。
建筑节能是改善广大人民的建筑热环境的需要。
随着现代化建设的发展和人民生活水平的提高,舒适的建筑热环境越来越成为人们生活的需要。
我国气候冬冷夏热的问题是相当突出的。
冬天需要采暖,夏天想要空调,而采暖和制冷都需要能源,其中对优质能源的需求量增长更快。
2 我国建筑节能存在的问题2.1效率低下随着中国经济快速发展,居民生活水平不断提高,采暖与空调使用量越来越大,导致建筑能耗大幅度增加,我国建筑能耗大概有50~60%用于供暖与空调。
我国北方地区冬季寒冷,主要依靠燃煤锅炉进行集体供热,由于锅炉的单台热功率较小,导致供热效率低下,并且大量燃煤造成空气污染。
2.2围护结构性能差我国围护结构保温隔热性能较差,墙体保温性能差,造成房间散热快,冬季室内气温普遍较低。

关键词:公共建筑;空调系统;节能设计中图分类号:TU83 文献标识码:A引言最近几年随着城镇建设规模的不断增加,人民生活水平的提高,建筑空调供暖需求产生了高增长,建筑能耗持续上升。
目前我国已经颁布实施了《公共建筑节能设计标准》,执行好节能设计标准,是实现我国建筑节能可持续发展的重要环节。
1公共建筑空调系统存在的问题1.1空调设备选型方面设备选型没有充分考虑空调系统的负荷特点和设备性能。
在实际使用中,即使在最热的月份,仍有闲置的制冷机组,大多数建筑的空调系统都不能达到满负荷运行。
这说明设计人员大多将空调的冷热负荷设计得过大,从而导致装机容量偏大,管道直径偏大,水泵配置偏大,末端设备偏大的“四大”现象,从而导致了初投资增加,能耗增大。
1.2建筑通风系统方面一般采用全空气空调系统或风机盘管加新风系统。
采用全空气系统可以在室外空气比焓低于室内空气比焓时充分利用室外新风供冷,从而节省冷水机组的制冷量。
但是在实际工程中,有些设计未充分考虑空调系统的全年节能运行,新风系统往往按最小新风量设计,新风接入口面积,新风管道尺寸及风机容量偏小,过渡季不能大量利用新风。
有些商场建筑即使在室外温度低至12℃时,室内还需要空调冷源设备供冷,造成极大的能源浪费。
另外,风机盘管加新风系统的设计,使风机盘管停止工作后,由于新风系统为定风量系统,照样向这些房间送新风,造成浪费。
1.3水系统方面目前采用的全是定水量系统,设计时水流量按最大冷负荷和5℃的供回水温差确定,但在全年运行中最大负荷出现的时间很少,绝大部分时间在部分负荷下运行,因此普遍存在大流量小温差的问题。
近年来许多研究结果表明,加大冷水供回水温差使输送系统减少的能耗大于由此导致的设备传热效率下降所增加的能耗,因此对整个空调系统而言具有一定的节能效益。

【关键词】公共建筑;建筑节能;建筑节能设计;重要性一、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多亿平方米,每年新建房屋面积高达17—18亿平方米,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.二、加强建筑节能,尤其是公共建筑节能的重要性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m2左右的大型公共建筑,耗电量为70-300kwh/m2•年,为住宅的8-15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,其采暖、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。
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.
