建筑综合用电指标
建筑综合用电指标1. 总能耗指标(Total Energy Consumption Index,TECI):用于表示建筑物总能耗水平。
TECI可根据建筑物的能源消耗计量数据和建筑物总面积计算得到,通常以单位面积的能耗量作为衡量标准。
2. 能源使用强度指标(Energy Intensity Index,EII):用于表示建筑物能源使用的强度水平,即建筑物每单位面积的能源消耗量。
EII可通过将建筑物的能源消耗除以建筑物的总面积得到,可以用于比较不同建筑物之间的能源使用情况。
3. 能源节约率指标(Energy Saving Rate Index,ESRI):用于表示建筑物能源节约的效果。
ESRI可通过比较不同时间段建筑物的能源消耗量,计算出节约的能源量占原能源消耗量的比例。
这个指标可以评估节能措施的实施效果,并为未来节能目标的制定提供依据。
4. 能源管理绩效指标(Energy Management Performance Index,EMPI):用于评估建筑物能源管理的效果。
EMPI可以通过综合考虑建筑物的能源消耗、能源节约率和能源成本等因素,计算得到一个综合指标,用于衡量能源管理的绩效水平。
5. 能源负荷指标(Energy Load Index,ELI):用于表示建筑物能源负荷的大小。
ELI可通过综合考虑建筑物的用电、用水和用气等能源消耗因素,计算得到一个综合指标,用于评估建筑物能源消耗的整体水平。
综合来看,建筑综合用电指标的目的是为了评估和改善建筑物的能源使用效率和节能水平。
通过收集和分析建筑物的能源消耗数据,建筑物管理者可以了解建筑物的能源使用情况,识别潜在的能源浪费问题,并制定相应的节能措施。
这有助于减少建筑物的能源消耗、降低能源成本、提高能源利用效率,并最终实现建筑物能源的可持续发展。

当前,中国建筑节能数据量化工作还存在一个短 板——缺乏建筑全寿命周期能耗和碳排放数据。
随 着我国城乡建设持续大规模推进,建筑材料的生产、建筑施工环节消耗了大量能源,产生了大量的碳排 放,建设领域对这部分的能源消耗和碳排放缺乏系统 研究和可靠的数据支撑。
推动建筑领域绿色低碳发展需要从全寿命周期 视角出发。
我国建筑领域从节能到绿色的转变,大规 模推广绿色建筑也正是基于此。
发展绿色建筑带来 的全寿命周期的节能与减排效果需要数据支撑。
因此,专委会构建了基于投入产出表与过程法相结合的 建材能耗与碳排放测算方法,测算并分析了 2005 - 2018年全国建筑全寿命周期能耗与碳排放数据。

中外建筑能耗比较分析 孙宝冬
中外建筑能耗比较分析孙宝冬摘要:本文对中外建筑用能分类和各类能耗数据进行了比较,分析了能耗差别产生的原因,并在此基础上总结了我国建筑用能总体状况和节能潜力。
同时指出各国能耗数据统计体系的差别,并提出数据比较应注意这些差别的影响。
关键词:建筑能耗;对比引言比较中外建筑能耗统计数据,对能耗差别的原因进行深入研究,可帮助我们更好地分析我国建筑用能现状、预测发展趋势,从而为制定相关政策和经济激励政策,引导建筑节能的发展提供依据。
根据国际上对建筑能耗统计的惯例,本文中的建筑能耗均指民用建筑运行使用过程中消耗的能源,不包括建筑材料生产用能、建筑材料运输用能、房屋建造和维修过程中的用能。
即研究民用建筑物内照明、采暖、空调和各类建筑内使用电器的能耗。
1建筑能耗分类建筑能耗数据统计是建筑节能工作的基础,而根据建筑能耗特点对建筑的分类又是能耗统计工作的基础。
欧美发达国家在进行建筑能耗统计时,将民用建筑分类为居住建筑(Reside-ntial Building)和商业建筑(Commercial Building)。
建筑细分中,居住建筑按体量分为单体住宅/别墅(singlehouse)和公寓楼(multi-house);商业建筑按功能细分为办公(office)、商场(shopping center)、酒店/旅馆(hotel)、医院(hospital)、学校(school),等等。
在统计结果中,根据建筑需求,分列采暖、空调、生活热水、炊事、照明、其他电器等项各自的能源消耗。
2建筑总能耗2004年,我国建筑能耗为1.7亿tce加5900亿kWh电,折合人均能耗937kWh/a,占我国社会总商品能耗的18.8%。
目前主要发达国家的建筑能耗均已占社会总能耗的1/3左右。
将我国建筑能耗与其他发达国家相比,可以发现,无论是单位面积能耗还是人均能耗,我国都远低于发达国家水平。
此外,我国城乡用能存在很大差异,即使只看我国城镇的建筑能耗,还是大大低于发达国家的平均水平。

1. 美国LEED (Leadership in Energy and Environmental Design):LEED是美国绿色建筑委员会(USGBC)颁布的一套绿色建筑评估系统。
它包括对公共建筑能源使用、水资源管理、室内环境质量等多个方面的要求,通过积分系统对建筑进行评估和认证。
2. 欧洲Union of the Electricity Industry (EURELECTRIC):EURELECTRIC 是欧洲电力行业的组织,其提出了一些关于公共建筑节能的建议和指南,包括设定建筑能源使用限额和采用高效能源系统等措施。
3. 欧盟Energy Performance of Buildings Directive (EPBD):欧盟发布了《建筑物能效指令》,要求成员国制定适用于公共和私人建筑物的能效要求,并建立建筑能源证书制度,用于评估和证明建筑的能源性能。
4. 中国GB/T 50378-2019《公共建筑节能设计标准》:中国国家标准委员会发布的《公共建筑节能设计标准》规定了公共建筑节能设计和标准要求,并要求公共建筑在能源使用方面达到一定的限额。
请注意,以上列举的标准仅供参考,具体的公共建筑能耗限额标准应根据当地国家或地区的法规和标准进行了解和遵守。
建筑业主、设计师和相关专业人员应与当地政府、能源部门或专业咨询机构合作,确保公共建筑满足相应的能源效
率要求,并实施适当的节能措施。

国内外建筑节能指标评析
国内外建筑节能指标评析建筑节能是指通过各种手段和措施,在建筑设计、施工和使用过程中有效地减少能源消耗,降低碳排放,提高建筑能效的一种方法。
国内外在建筑节能方面都制定了相应的指标,以评估建筑节能程度。
下面对国内外建筑节能指标进行评析。
国内建筑节能指标主要有以下几个方面:1.建筑能耗限额:在建筑设计阶段,规定建筑所能消耗的能源总量上限,通常以每平方米建筑面积的能耗限额进行衡量。
这是国内建筑节能的核心指标之一,目的是强制设计师在设计阶段就考虑节能措施。
2.建筑能效等级:根据建筑所达到的能效标准,将建筑分为不同的等级,例如国内的绿色建筑星级评定标准中的三星级、四星级和五星级等。
这是评估建筑节能程度的重要指标之一,也是对建筑进行评估和认证的依据。
3.传热系数:建筑外墙、屋顶等构件的传热系数是评估建筑隔热性能的重要指标之一、传热系数越小,表示隔热性能越好,能够有效降低建筑的能耗。
4.窗户日照系数和热传递系数:建筑窗户的日照系数是评估建筑采光性能的指标,热传递系数是评估窗户隔热性能的指标。
合理设计窗户的日照系数和热传递系数,可以充分利用自然光和减少采暖和冷却的能耗。
5.水利用率:建筑的水利用率是指单位建筑面积所消耗的水量。
对于建筑来说,节约用水是建筑节能的重要方面之一、通过采用节水器具、回收再利用等措施,可以降低建筑的水耗。
国外建筑节能指标也有相应的规定1. LEED评估:LEED(Leadership in Energy and Environmental Design)是世界上最重要的绿色建筑评估体系之一,主要评估建筑的节能、水资源、材料使用、室内环境质量、可持续发展等方面。
根据所达到的评分,将建筑分为不同的级别。
2. BREEAM评估:BREEAM(Building Research Establishment Environmental Assessment Method)是英国广泛采用的绿色建筑评估体系,类似于LEED。

Benchmark i n g of energy eff ic iency standards for residen ti a l bu ild i n gs i n Ch i na
n China, coup led with the rap id econom ic development and urbanization in the past two decades, various build2 ings have been rap idly established and energy consump tion, especially electricity use, has sharp ly increased. The Chi2 nese building sector accounted for 23% of the total energy use and increased to one 2third by the end of 2009. The ener2 gy consump tion in the residential sector increased by 14% from 1996 to 2001 in which air2conditioning and heating ac2 counted for 55% of the total energy consump tion. The build2 ing energy consump tion data, which is nearly twice that of residential buildings in developed countries under the same climate conditions, indicate that many traditional residential [1 ] buildings are not energy efficient . Therefore, more measurements should be taken to reduce the energy con2 sumed for air2conditioning and heating while maintaining comfortable indoor thermal environments in residential buildings . In China, energy efficiency efforts began in the early 1980 s . The first building energy code “ Energy Conservation Standard for New Heating in Residential Buildings JGJ 26 — [2 ] 1986 ”was introduced in 1986 . Since then, many other codes have been introduced to different climate zones in

建筑学外文翻译—绿色建筑在中国需要伟大的推广
建筑学外文翻译—绿色建筑在中国需要伟大的推广课题英文名称Green building in China: Needs great promotion课题中文名称原文:Green building in China: Needs great promotion AbstractResource depletion and environment pollution is a great challenge in the world today. As the main human living environment, building is one of the main contributor of energy consumption and pollution emission, construction industry has become the focus of energy conservation and emission reduction. China has been the world's largest carbon emitter and the world's largest energy consumer country since 2011. To solve these two issues, the promotion of green building (GB) is of great urgency. This article analyzed GB situation and challenges in China, and then pointed out some special requirements of GB. At last, authors put forward some suggestions to promote the development of GB according to current situations in China including: taking measures to enhance awareness of stakeholders, strengthening technology research and communication and establishing codes and regulations.KeywordsGreen building;Building energy consumption;Energy-saving1. Introduction1.1. The concept of green buildingThe concept of GB in China is developed from “Energy-Saving and Land-Saving Residential Building” launched by th e central government in 2004. T o be specific, the GB should be energy-saving, land-saving, water-saving and material-saving, environment-benign and pollution-reducing, summarized as “Four-daving and One-benign”. It is defined in Chinese national standard, Evaluation Standard for Green Building, enacted in 2006 (Ministry of Construction, 2006). The so-called “green”, is not the general meaning of green, but a conc ept or symbol. It stresses people-oriented and puts emphasis on sustainable development and environmental symbiosis to achieve harmonious coexistence among people, nature and building. GB is also known as ecological building, sustainable building, energy-saving building, etc. Its ultimate goal is low consumption and low emission, but the “low” does not mean high-tech or high investment. Actually, GB is a climate adaptative building, which requires adopting appropriate technology as much as possible to reduce energy consumption, meanwhile materials should be recycled and fully localized to achieve the lowest cost of energy and comfort.1.2. Origin of green buildingThe curator of Architecture and Design Library in American National Building Museum, Giessen David, pointed out that the seeds of GB can trace back to a century or more ago. According to this, the birth of British Palace in the first world expo and Galleria Vittorio Emmanuele in Milan in the early 19th century have begun to use passive system such as roof fan and underground air cooling box to regulate indoor temperature. Early at the 20th century, Flatiron Building and New York Times Building in US have designed windows embedded into walls toreduce sunlight. Ecological system and natural environment have already been taken into consideration in early architectural design, which become the buds of green building. Until the 1960s, American architect Paola Soleri combined the two words “ecology” and “building” together, and put forward the new idea of “ecological building” (green buildin g). In 1969, the publication of the book “Design with Nature” by American architect Ian Lennox McHarg, marked the birth of ecological architecture. Through more than half a century, GB has become a new building style that fully integrated energy-saving, building design and environmental-protection from its initial simple mode, and it is more adaptable to current situation of energy shortage, so it is a new trend of building development model.1.3. Global actions to develop green buildingTo create a better environment for developing GB, countries around the world began to formulate relevant standards. The United States enacted the ASHRAE (American Society of Heating Refrigerating and Airconditioning Engineers) standard “En ergy-saving in Design for New Build ing” for the first time in 1975. UK began to create GB standards as early as in 1990(Chegut et al., 2011), and all buildings should satisfy green building criteria from 2008 in Britain (Bulkeley et al., 2011); In 2009, Britain announced Low Carbon Transition Plan, required all new buildings achieving zero-emission from 2016, all new public buildings from 2018, all office buildings from 2019 and all residential finish Smart Meters installation before 2020 (Peters, Fudge, & Sinclair, 2010). Recently, European Union promulgated a more advanced and perfect legal system in energy saving field, which is entitled Building Energy Efficiency Performance Law. The law requires all state or state-use new buildings must be close tozero energy consumption by 2020. From an early start, building energy-saving work had achieved great achievements in some developed countries. In Denmark, Heating area increased by 30% from 1972 to 1985, but the heating energy consumption decreased by 3.18 million tons of standard coal; in America, 43 billion dollars is saved in energy cost and environment management since the first energy-saving standard to 2011 (Danielski, 2012).GB in China started relatively late. In 1996, New Urban Building Energy Efficient Standard System was issued, which is composed by the residential building energy conservation design standard. Residential Building energy conservation Design Standard of Hot Summer and Cold Winter Region was issued in 2001 and was updated in 2003. In September 2004 with the start of Green Building Innovation Award, GB in China stepped into a comprehensive developing stage. In 2006, Evaluation Standard for Green Building was officially promulgated. Evaluation Standards for Green Industrial Building and Evaluation Standards for Green Office Building started in 2009 and 2010, respectively. At present, at least 50% building energy efficiency is achieved in almost all regions of China, unlike some big cities as Beijing, Shanghai and Tianjin are executing the standards which require energyefficiency must achieve at least 65%, while Beijing is executing the new goal of 75% since “12th Year Plan” (Li and Wang, 2012 and National People's Congress, 2011). However, building industrialization just starts in China, and there is still a great gap comparing with foreign countries.2. Why to develop green building2.1. To reduce CO2 emissionOn 3rd, December 2012, the famous journal “Nature” published an au thoritative scientific research report. According to the report, the global CO2 emission has increased to record 35.6 billion tons in 2012, and the largest carbon emission countries in 2011 are: China (28%), United States (16%), European Union (11%) and India (7%). Among them, emissions of China and India in 2011 increased by 9.9% and 7.5% respectively, while United States and European Union reduced by 1.8% and 1.8% respectively (Nature Climate Chenge, 2013). China has become No.1 CO2 emitter country in the world, surpassing U.S. in 2007 with approximately 8% more emission (IEA, 2011). According to EIA (Energy Information Administration) estimation, CO2emission in United States will be 5.68 billion tons in 2015, but it will be far more than this in China (EIA, 2011). In “12th five-year plan” in China, the carbon emission in 2015 is 7.89 billion tons, which is 2.21 billion tons higher than the United States, if the total energy consumption is more than 4.1 billion tons, the carbon emission gap between China and United States will be more huge. China is in great pressure.The greatly increasing emission further expands the gap between actual emission and the goal to control global warming within 2 °C. To ensure the global warming within 2 °C, the global carbon emission must be deeply cut by 2020 (Huntingford et al., 2012). In China, it has been decided that 17 percent reduction of carbon dioxide emissions for every GDP unit should be achieved by the end of 2015(Yu & Qu, 2013), and 40–45% by 2020 further (Yi, Zou, Guo, Wang, & Wei, 2011).Among all elements, buildings account for around half of primary energy consumption, hence CO2emissions, in the UK and other developed countries (Ratcliffe & Day, 2007). Buildingemission mainly refers to the consumption of resources and greenhouse gases produced from consumption throughout the lifecycle of buildings, so it is closely related to human daily life and work. 50% people may cause carbon-emission by using vehicle, 30% people may be involved in industrial production, but there must be more than 90% or even more people causing endless carbon-emission because of thei r daily life and work. So the “energy-saving” and “low-carbon” in construction are destined to become a hot topic. Study has shown that the global construction industry and its related fields caused 70% of greenhouse effect from the production of building materials to construction and use of buildings, the whole is a huge emitter of greenhouse gases (Zuo, Read, Pullen, & Shi, 2012).2.2. To relieve the energy crisisChina is the world's largest energy consumer now. The global net primary energy consumption grew by 2.5% in 2011, and China alone contributed 71% of global energy consumption increment. In 2011, global coal consumption increased by 5.4%, China accounted for 69%. The total primary energy consumption in China has been more than that in the United States in 2011 (Global, 2012). With the fast development, more energy will be consumed in China. Butthe coal-dominant energy structure in China is difficult to change in a short time, and now the coal production has exceeded the scientific capacity. In the future it is difficult to satisfy the needs even all the fossial energy were gathered in the world. Outside the pressure of carbon emission, for China the bigger challenge is that the energy consumption continues to increase. Energy consumption in EU grow at a rate of 1–2% per year, and in US it has entered slight growth stage, but China'senergy consumption is still growing at a rate of 5–6% per year, total energy consumption in China will be alarming under this situation.3. Green building situation in China3.1. Building energy consumption in ChinaIn China, building energy consumption accounts for 46.7% of the total society energy consumption, and 60% of the carbon emission in cities comes from maintaining buildings’ function (Zhang, 2010). Due to the rapid development of economy development and urbanization in recent years, about 20 × 108 m2 building areas are completed each year, which is larger than the total area in European and American (Zhao, Zhu, & Wu, 2009). In China, about 55 kg steel will be used in each 1 m2 building, and it is 10–25% more than developed countries; about 221.5 kg cement will be used in each 1 m3 concrete, and it is 80 kg more than developed countries (Zhang & Gu, 2012). The existing building areas are 430 × 108 m2 in China, 90% o f them are high energy consumption construction. Compared with developed countries, the thermal isulation performance building envelope is poor, as shown in Table 1, the larger the number is, the faster heat run off. The heat transfer coefficient of all parts in China is 2–3 times higher than developed countries (RGBI, 2010). Due to poor thermalinsulation of building envelope and low efficiency of heating systems, energy consumption for heating in north China is the largest component of building energy consumption (BEC), as shown in Fig. 1(Cai, Wu, Zhong, & Ren, 2009). In addition, it is about 25 kg/m2 standard coal in China, which is 2–4 times larger than that of Northern Europe in similar climate, and carbon emissions are 2–5 times higher than international standard (Qi &Li, 2013).3.2. Achievements of the Green Building in ChinaAlthough ten years later than western countries, GB in China develops rapidly. Especially in recent five years, GB in China developed at an alarming speed every year (Fig. 2) (Green building map, 2013). In China, GB evaluation standards mainly used are LEED rating system issued by USGBC (U.S. Green Building Council) and Three-Star rating system issued by Chinese government. The number of Three-Star projects in 2009 increased by 100% than 2008, and the number in 2010 increased by 290% than 2009. The green building number and area in 2012 is equivalent to the sum from 2008 to 2011(Sun & Zhao, 2013). The number of LEED projects every year is shown in Fig. 3 (Jerome Sebbag, 2013). They are almost in the same increasing trend. The minister of Ministry of Construction, Qiu baoxing pointed out that, in 2005, buildings executed energy efficiency standards in design stage only account for 53%, performing stage 21%, but after five years, the proportion increased to 99% and 99% respectively (Qiu, 2011). During the “11th five-year plan” period, GB demonstration area reached 13,000,000 m2, the accumulative total GDP energy consumption fell 19.1%, the building energy saving contributed 20% of the energy saving (Li et al., 2011). During “12th fiveyear”, China plan to complete new GB 1 billion square meters and 20% of new buildings in cities and towns can reach GB standards by the end of 2015.3.3. Features in the development3.3.1. High proportion of national projectsAccording to research, most GB projects are directed by the national agencies, directed by local agencies only account forabout 27% of the total number in 2010 and 2011, as shown in Fig.4 (CABR, 2012). The reason for this is China is still in the initial stage of GB, neither developers nor consumers have a strong consciousness to promote green building. So this has become an obstacle on the way to develop GB. A relatively clear thing is that both GB directed by national agencies and by local agencies were increasing rapidly over the last 2 years and they were approximately at the same rate.3.3.2. Most certificated in design stageChinese Three-Star Evaluation System includes design stage labels and operation stage labels. The number of GB in the design stage is 331 while 22 in the operation stage. The ratios of green building number in design stage to that in operation stage in 2009, 2010 and 2011, are 9.0, 9.5 and 19.0 respectively (there is no GB for operation stage in 2008) (Ye, Cheng, Wang, Lin, & Ren, 2013). We can easily find that most GB are certificated in design stage (CABR, 2013). Why not these buildings take part in evaluation in operation stage? After asurvey on these green buildings, we find that most of them cannot achieve green standard in the operation stage due to the lack of mature technology and skilled worker.3.3.3. Rising of residential buildingsThe numbers of residential and public GB projects are 193 (54.7%) and 160 (45.3%) respectively. A massive rise of residential projects is evident. Recent policy on social housing in China may be one reason for the large rising in residential projects, and this is expected to continue (Ye et al., 2013).3.3.4. Unbalanced regional developmentAs shown in Fig. 5, counted by province, autonomous region,municipality and special administrative region, Jiangsu Province ranks the first, accounting for nearly a quarter of the total, and it is followed by Guangdong Province and Shanghai (CABR, 2013). More than three quarters of green buildings are in the east coast, which is the region with a rapid economic growth in China, ss shown in Fig. 6 (Ye et al., 2013). Although western China accounts for two-thirds of China's total area, its proportion is less than 10%.4. Special requirements for green building4.1. ComfortEnergy-saving and emission-reduction is just one of the requirements of GB. Some people think GB is just to save energy and reduce emission, for example, they think building with solar energy or ground source heat pump is green, but this concept is totally wrong. Real green building is not only energy-saving, emission reduction or land-saving, but also meansproviding a comfortable working or living environment for human, which is considered as the key part.4.2. LifecycleGB should be judged from the whole life cycle, we cannot just see whether it uses energy-saving equipment in the early design process. Developers should consider energy consumption required in material, operation and maintenance, etc., in addition, energy needed when it is broken down is also included.4.3. Not equal to high costSome think GB is expensive luxury goods, and it needs high cost. Actually, GB should be considered from the whole life cycle, it stresses efficiency of resources through optimization design, emphasis on localization of materials and adaptation to local conditions, even the construction cost may increase, it can be recovered from energy saving, water saving, resources savingand so on in operation phase. According to statistical results, the incremental part of the green building cost accounts for about 2.7–9.3% in the overall cost in the construction (Yudelson, 2008). Appropriate investment in early time leads to savings in the process of operation and its energy-saving benefits can be seen after some years. According to general calculation, it needs seven years to recoup the costs, but the time is expected to be much short. Overall, the incremental cost is decreasing. Prejudice on the initial cost is one of the main obstacles in GB development. In addition, benefits of GB buildings are often social shared, while initial cost is bared by developers. To some extent, balance between interests and responsibility hinders the development of GB.4.4. Not equal to high-techThe essence of GB is to make the building adapt to the climate. To let the building have adaptation function, high technology is one of the means to reach standards of GB, but it is not the only way. GB should follow the “passive priority, active measures optimization” principle. Passive measures refer to directly use natural conditions such as sunlight, wind, topography etc. to reduce the building heating, air conditioning and lighting load. Active measures refer to use mechanical systems to improve the indoor comfort, it usually including heating, air conditioning, mechanical ventilation, artificial lighting, and other measures.5. How to promoteGB has risen to be a national strategic action. All sectors in China society should work together to develop the low carbon buildings, where update of consciousness is the foundation, technology innovation is the key, and system monitoring is theimportant measure.5.1. To enhance the awareness of the stakeholdersAs an officer once said, “The b iggest problem is how to improve energy saving awareness among residents who only care about the price and location when they choose residences”. At present, in the process of GB development in China, GB is mainly constructed by government through several of policies and specific plans. In fact, for most developers, the goal is to pursue profit, but for consumers, they care about good cost performance, whether green or not are none of their business. The social benefits of GB are not awarded, such as energy saving, environmental protection, comfort and low cost, they just have been accepted a bit. Measures must be taken to enhance awareness of stakeholders, especially the residents.First, government should further study how investments in GB contribute to a vibrant local economy like jobs, business and tax revenues. The government can arrange some reports about the concept of GB, and issue statements supporting the economic, environmental and social interests of GB. For example, “air quality, lighting, heat and green building air conditioning and overall can be improved in GB, a more pleasant, healthier and productive place to live. The people who live and work in GB appears be more healthy.”Second, government can be partner with building industry associations to set up workshops to demonstrate the statement mentioned above. It might present to developers the legal case and business case for GB to increase awareness and strengthen market valuation.Third, government should launch a communication campaign to inform developers and building owners or tenantsthat GB offers a higher net operation income, thus increasing the value of the building, offering lower operating costs and improving image in the community.5.2. To strengthen technology research and communicationLack of knowledge and backward of technology have become an obstacle GB development. Lack of science and technology, key technologies for GB are insufficient and bottlenecks for GB have not been broken yet. Even now, China does not have a complete technology system on GB construction. Rapid transformation of energy-saving construction market depends on new technologies particularly. Many Chinese institutions support research and development of energy-saving technology, however, many innovative technology in China is still in research stage and has not yet been commercialized due to lack of effective platform to promote, demonstrate and communicate new technologies. Developed counties have achieved greatresults in GB technology research, and complete technology systems have already formed during long time development, so we have to strengthen technology research and communication with developed counties to get some experience, only then can we get most in shortest time.The government should continue to support energy-saving technology research and development to promote technical communication, so as to improve the commercial level of innovative energy-saving technologies and market penetration ability; Institute and university should strengthen the research, demonstration and test of innovative energy-saving technologies. Various technique applications in building energy-saving are shown in Fig. 7 (Ye et al., 2013). It indicates that Chinashould focus on development of utilization technology of new energy and renewable energy to accelerate intelligent construction development. Meanwhile, the intelligent building is an important part. At present, the intelligent buildings ratio in new buildings is as follows: 70% in the US, 60% in Japan, and China only about 10% in 2006, it is expected to increase to around 35% in 2013. The potential of intelligent building industry development is great, so it is considered to be a very important industry in China.5.3. Codes and regulations5.3.1. Evaluation standardsTo address the energy production issue, China has launched a wave of legislation about green building since 2005. In spite of some national and local standards, we do not have a complete system on the design, construction, operation and evaluation of GB. Although the climate indifferent areas in China is different, we do not have specific standards for different regions. GB in China is still in the initial stage, related policies, regulations and evaluation system still need to be improved. GB standards should adjust to local conditions, and provide different guidance to different situations. Factors including regional economic development level, resources amount, climate conditions and construction characteristics must be taken into consideration when establish and perfect GB standards and formulate targeted policy measures. What's more, to keep accordance with the progress of construction technology, it is essential to constantly update the building regulations.5.3.2. Evaluation systemEvaluation systems should contain quantitative standardswith high qualities, so research and application on quantitative and qualitative index must be enhanced. To advocate the GB development and practice GB certification institution, the government must cultivate an independence third-party certification agency to make fully evaluate before implementing design proposal, under construction process and building materials and devices. GB lifecycle evaluation focuses on whole environmental assessment, and each phase of evaluation is based on overall grasps (Yudelson, 2008).5.3.3. Legal managementLegislation is the fundamental in promoting GB. Although we have issued many standards for many years, many building energy efficiency standards had not achieved its supposed effect. The Ministry of Housing and Urban-Rural Development of China (MOHURD) investigated more than 3000 projects in 2005, the result showed that only 58.53% of those projects were designed with related energy efficiency standard, and only 23.25% of them are built to match the energy efficiency standard. Therefore, strict scrutiny into enforcement of building energy efficiency standard has been adopted by MOHURD and the legal enforcement notes will be sent to those projects which disobey the compulsory standard. By this action, the percentages of building projects that designed to match the energy efficiency standards was up to 95.7%, and built to match those standards was up to 53.8% in 2006; the percentages were up to 97% and 71% in 2007 (Zhang & Gu, 2012). The requirements of building energy saving are considered to be issued in the form of law or regulation. It is essential to use law ways to guarantee operation of new building energy efficiency standards.5.3.4. Multi-incentive toolsIn China, incentive policies to promote development of GB are insufficient in current. Incentive policies on finance, tax and economy are not sound, related sectors cannot get strong internal motivations to develop GB. Although there are some incentive policies related to building energy saving, water saving and environmental protection tax, there is not specific policy for green building tax or finance. Real estate developers cannot get any incentives in terms of land acquisition, project examination and approval, finance when develop GB; Encouragement Measures are not evident when consumers purchase GB; so GB cannot realize a dominant demand in market. Efforts are necessary to set more incentive tools at the right level to improve energy saving and GB ratio.To developers: In the current property rights regime in China, the land was owned by the government or collective. The developer has to pay an amount to government for land use right. To promote GB development, the government could pay back a portion of money to developer if building turns out to be a GB. China can model itself following America to grant reduced construction fees for projects which earn GB star label, where the fee cost varies as the label level. This would be an effective way to promote the developer take action to make buildings green.To owner and tenant: The incentives to the owner and tenant are also necessary. If tenant prefers to live in the energy-efficient buildings or consumer is inclined to choose GB, it will push the real estate industry to meet GB standard. But most people care about price when buy or rent GB because it is more expensive than the normal building. How to solve this problem? The answer lies in direct economic incentives, such as tax reduction. In China,when the citizens purchase and transfer the possession of houses, massive taxes will be imposed. Chinese government can consider granting some tax reduction to people who purchase GB. However, this way may not be effective for the tenant for the short lease. The price, position and operating costs of houses are concerned with tenants. It might be effective to follow the energy certification approach of EU-when a house is for rent. An energy performance certification must be made available to the tenant.6. ConclusionsIn recent years, China has begun to pay attention to research and construction of GB and has taken some actions. However, the current study only focuses on the green construction methods, which are too narrow; building of green construction is only pilot projectand has not formed a green construction complex. So there should be further study about the scale development of green building.译文:绿色建筑在中国:需要伟大的推广摘要:资源枯竭和环境污染是当今世界一个巨大的挑战。
建筑能耗计算公式
建筑能耗计算公式
建筑能耗计算公式主要基于建筑的能耗需求和能源消耗情况进行计算,具体公式如下:
1. 建筑总能耗(Total Energy Consumption):
Total Energy Consumption = 高温能耗 + 中温能耗 + 低温能耗+ 空调能耗 + 照明能耗 + 其他能耗
2. 高温能耗计算公式:
高温能耗 = 高温设备数量 * 单个高温设备耗能
3. 中温能耗计算公式:
中温能耗 = 中温设备数量 * 单个中温设备耗能
4. 低温能耗计算公式:
低温能耗 = 低温设备数量 * 单个低温设备耗能
5. 空调能耗计算公式:
空调能耗 = 空调设备数量 * 单个空调设备耗能
6. 照明能耗计算公式:
照明能耗 = 照明设备数量 * 单个照明设备耗能
7. 其他能耗计算公式:
其他能耗 = 其他设备数量 * 单个其他设备耗能
以上公式中,设备耗能需要根据该设备的具体能耗数据进行计
算。
同时,建筑能耗计算还需要考虑建筑的使用时间、运行模式、能源效率等因素。
因此,在实际应用中,还需结合建筑能源管理系统、能耗监测设备等来获取准确的能耗数据,并进行综合分析和计算。

建筑领域能耗与碳排放的界定与核算
建筑领域能耗与碳排放的界定与核算[摘要]过去二十年,中国的快速城镇化带动了建筑规模的持续增长,中国建筑领域的能源消费与碳排放是已成为全社会能源消费与排放的重要组成局部。
同时,中国正处于能源供应与消费方式变革的关键节点,因此,对中国建筑能耗与碳排放的现状进行全面认识和分析具有重要意义。
为此,本研究对中国建筑领域的能耗与温室气体排放进行了界定,并建立了中国建筑能耗和排放模型(ChinaBuildingEnergyandEmissionModel),基于统计数据及实测调研数据对中国的建筑规模、建筑及运行阶段的用能和排放进行了计算,并结合对我国建筑领域的用能及排放特点,提出建筑领域节能与低碳开展的政策建议。
[关键词]建筑节能;自下而上模型;能耗;碳排放;低碳开展中国建筑领域的能源消费与排放是全社会能源消费与排放的重要组成局部,也是中国节能减排以及能源消费变革工作的重点。
过去二十年,中国城镇化开展迅速,建筑规模的迅速增长也带动了我国建筑领域用能与排放的持续增长。
一方面,大规模的建设活动消耗大量建材,这些建材的生产、运输等过程产生了大量的能耗与排放,在我国全社会占有相当的比例[1]。
另一方面,不断增长的建筑面积也导致了更多的建筑运行用能,加之随着经济社会的开展,人民的生活水平不断提升,使得采暖、空调、生活热水、家用电器等终端用能需求和产生的碳排放也不断上升[2]。
中国建筑运行用能约占全社会总用能的20%,由建筑建筑所导致的原材料开采、建材生产、运输以及现场施工的能耗也占到全社会总能耗的20%以上。
目前,中国仍处于经济相对快速开展的阶段,能源消费结构不断发生变化,从物质生产领域向建筑和交通领域转移[3]。
建筑用能作为类消费领域用能的主要局部,其重要性也将不断增加。
同时,国内国际正处于能源供需格局变化的关键节点,在能源供应结构变革的大背景下,建筑领域的能源消费的开展也应与之相适应。
在上述背景下,对中国建筑用能与排放的现状进行全面认识和分析具有重要意义。
