Global environmental issues have drawn wide attention increasingly all over the world since 21st century. As a major responsible country for envi-ronmental protection, China ta-kes sustainable development as its basic national policy, adopts scientific approach for develop-ment, participates in resolving global environmental problems actively, and makes continuously efforts for global environmental protection. So far, China has ra-tified or accessed to more than 30 international environmental conventions. The corresponding mechanisms were built and related laws and regulations were formulated and rectified for implementing conventions. China has done the best to shoulder international envi-ronmental responsibilities and obligations matching current development level, thus, making positive contribution to global environmental protection. In order to further enhance the capacity of implementing conventions, Chinese gover-nment approved of constructing Environmental Conventions Bu-ilding. The construction gained strong supports from related ministries and Beijing municipal government, and attracted great attention and participation from international community.

Foreign countries, interna-tional organizations, as well as all society provided funds, technologies and equipments for the realization of the Building, with special thanks to Italian government, Multilateral Fund for Implementation of the Montreal Protocol. Experts, both from China and abroad, have explored design and its construction. The Building declares China’s positive and careful attitude on global environmental problems and promotes conventions implementation capacity. The completion of the Building will facilitate the cooperation pro-gress and develop multilateral and bilateral cooperation. China’s Environmental Protec-tion has received strong and effective supports from relevant internal and external agencies during past years. Meanwhile, international environmental cooperation builds a platform for China’s development, and enhances friendships with other countries. The Building is a model of international envi-ronment cooperation between China and other countries. China highly appreciates the contribution from Italian gover-nment, the Executive Commit-tee of the Multilateral Fund for

the Implementation of Montreal Protocol and World Bank etc. We would like to extend our heartfelt gratitude and respect to related governments and international organizations for their long-term support.The political willingness, prag-matic actions and concerted efforts from all governments are required for addressing trans-boundary environmental problems in 21st century. The global environmental problems can not be solved without the participation of China, likewise, China’s environmental issues need understanding and sup-port from the world. Let’s join hands together to take good care of the earth—the common homeland of all mankind and compose new chapters for our brighter future.

序言 PREFACE

ZHOU JIAN

The building sector accounts for over 40 per cent of the world’s primary energy consumption as well as nearly a quarter of global CO2 emis-sions, and it is a key battle-ground in the fight to reduce emissions.The building sector is a driving force in the development of China.Considering the global and the national environmental impact of the building sector, the Italian Ministry for the Environment of Italy (IMELS) and the Chinese Authorities, within the Sino-Italian Program for Environmen-tal Protection, has been jointly carrying out since year 2003 a group of construction and planning projects in the main metropolitan areas of Eastern China.Excellence in design, excellence in technologies, excellence in environmental protection. Under these three principles, IMELS is involving affirmed Italian architects and promoting Italian leading construction technologies and equipments to showcase the “Italian Way” to sustainable design & construc-tion and its applicability in the sustainable urban development of Chinese cities.Among the Sino-Italian projects, the “Sino-Italian Eco-Efficient Building” in the Beijing Tsinghua University, completed in 2006, and the Environmen-tal Conventions Building/4C Building are a landmark in the Chinese capital city .The Environmental Conventions Building/4C Building is an intel-ligent, ecological and energy-efficient building, designed by Italian architects and

society, that has characterized the last two decades, is a phe-nomenon that implies an ever growing expansion of Chinese cities, with ever mounting need to host new infrastructures and new building endowment, with more need to set up solutionsto mitigate the impact of the urban realm.As already mentioned, the realization of the Environmen-tal Conventions Building/4C Building it is not the only experience in such a coopera-tion field carried out by IMELS in China, not even the first one in Beijing, but it embodies a top symbolic value, for the building hosts the international activities of the Chinese Ministry of Envi-ronmental Protection, as well as the premises of the Sino-Italian Collaboration Program for Envi-ronmental Protection.Located on a highly attractive and centric spot of Beijing the Environmental Conventions Building/4C Building exemplifies aesthetic values, environmental protection, energy-efficiency and functional effectiveness. Its presence shall remind to us all about how these factors may be successfully combined together in the journey towards sustai-nable development and towards enhancing the quality of life in the built environment.

Corrado CliniDirector General

supplied with the most advan-ced technologies in materials, energy efficiency, renewables, and water uses. The Environmental Conven-tions Building/4C Building is a model for a new generation of buildings and an example for the dissemination of sustaina-ble practices in the Chinese building industry, which has a rushing development: through the use of a specifically con-ceived architectural shape, the choice of proper construction materials, the installation of energy-efficient equipment, the adoption of a wise building management system, it is possible to dramatically reduce the energy demand of a built structure. In this overall process, Italy has a long and acknowledged tradition and IMELS is proud of facilitating the deployment of Italian know-how to be com-bined together with Chinese experience.The demonstration of environ-mental design & construction practices is not only a matter of environmental self-awareness: it will also pave the way to the compliance to new environmen-tal standards and requirements that are ready to be endorsed by the international community. Moreover, the diffusion of such practices will lead as well to the development of more affordable environmental technologies, reducing the gap between the construction costs of an eco-building with respect to those of an ordinary building. This innovative attitude is even more important when matched with some macro-dynamics that can be easily observed especial-ly in China, where the constant shift from a rural to a urban

建筑行业每年的能源消耗超过全世界能源总消耗的40%，占全球二氧化碳排放量的四分之一，是减排战争中的重头戏。同时，建筑业也是中国经济发展的重要推动力。考虑到全球和国际建筑领域对环境的影响，意大利环境部和中国政府在中意环保合作计划的框架下，自2003年起联手在中国东部主要大城市展开了一系列建筑和规划项目。卓越的设计，卓越的技术，卓越的环保。根据这三项原则，意大利环境部召集意大利建筑师参与，并运用意大利领先的建筑技术和设备，展示了在可持续设计与施工方面的“意大利方法”，及其在中国可持续城市发展中的适用性。中意项目之中，北京清华大学“中意环境节能楼”已于2006年完工，而中国首都的环境国际公约履约大楼（4C大楼）又将是一项具有里程碑意义的建筑。4C大楼是一座智能型的生态节能建筑，它由意大利建筑师设计，在建筑材料、节能、可再生能源和水资源利用等方面，都采用了最先进的技术。4C大楼是一个新时期的建筑标杆，为在中国急速发展的建筑业推广可持续发展的实践提供了样板：通过构思巧妙的建筑造型、合适的建筑材料、节能设施、先进的楼宇管理系统，可显著减少整座建筑对能源的需求。

在整个过程中，令意大利环境部感到自豪的是，他们凭借意大利自身的传统优势，成功地将意大利的技巧与中国的经验相结合。开展环保建筑设计与施工的示范工作，不仅体现了自觉的环境意识，同时也为遵循即将得到国际社会认同的新环境标准及要求铺平了道路。此外，这些实践的推广，也将促进更经济的环保技术的发展，缩小生态建筑与普通建筑在建设成本上的差距。这种创新的态度，更重要的是与当前中国的宏观形势相呼应。过去20年来，农村城市化进程将城市数量不断扩大，这一现象意味着日益增多的中国城市需要修建更多的基础设施和新的建筑，更加需要寻求新的解决方法来缓解城市化带来的负面影响。如前所述，履约大楼的建设并不是意大利环境部与中国在该领域中的唯一合作，也不是在北京合作建造的第一座建筑，它的真正意义在于，这座大楼将成为中国环境保护部开展国际合作的主要场所，同时也是中意环保合作计划的办公场地。

Corrado Clini司长

Environmental Conventions Building/4C Building is one of the locations of the Ministry of Environmental Protection (MEP), more actually, the loca-tion of a government agency responsible for management and inspection of activities related to the implementation of environmental agreements. It is obvious that the coope-ration between the Ministry of Environmental Protection of Italy and the Ministry of Environmental Protection of China is totally initiated from the implementation of relevant environmental protection and major international agreements (from the Montreal Proto-col for protection of ozone layer through convention on persistent organic pollutants to United Nations Framework Convention on Climate Chan-ge). The construction of the bu-ilding with the goal I mentioned is partially sponsored by the multilateral foundation of Mon-treal Protocol for protection of ozone layer. The construction industry is one of the major parties responsible for energy consumption of a country eve-rywhere after all. It is true that the participation of the Ministry of Environmental Protection in the realization of the building plays a key role.The challenge of the project is to create a systematical building. Apart from space for offices, it should feature extremely efficient energy, extensive use of materials, devices/systems of Italian renewable products, highly aesthetic and functional design and competitive perfor-mance/price ratio in Chinese market.

The last point is crucial as we hope the building should also demonstrate the possibility of creating an ecologically persistent building with high performance and high quality at limited cost. These characteristics will be explained in details in following pages. The architectural profile is a further challenge raised by Bei-jing Municipal Urban Planning Bureau, which expected the façade of the building facing the second ring road (the road with heavy traffic around the most central part of the urban area) to embody magnificence in both form and colors. A lot of acuity and finesse from Architect Mario Occhiuto was involved in the building. He combined the demand on profile and the necessary climatic protection of the facade facing north and created an extremely clean and simple surface lightened by some architectural elements (such as horizontal cuts present on windows and vertical curved glass curtain wall) that form a pleasant integration on the basis of restriction required.The curved glass curtain wall on the facade of the building is connected to the left side of the building that is also curved and fitted with glass curtain wall, reaching the south facade in the back naturally without any artificial intervention and brightly open to the public area backward. People can enter the building from the south with continuous surprises as photos do not correctly show the interior.

Aided by two “light machines” like “sunlight” large chandeliers, the light illuminates the inner court and the pleasant floor in the hall like two bright fantasies by light art master Ingo Maurer. I do not know if this building will be available for visit, but it must be worth. Incredibly, what makes me truly pleasant is that I participated in the project at the early prepara-tion stage. The most important is that it not only followed the primary goal of performance, but also successfully controlled the cost absolutely according to “market” level. Just like my words in the begin-ning, this building characterizes demonstration for us. The final result is completely positive and makes us and our Chinese colleagues to realize that even in a small scope, we can also successfully contribute to principles of ecologically su-stainable development in China and the popularity of technolo-gies. Although this building has such a short name of 4C, it will make huge contribution to the global environmental protection.

环境国际公约履约大楼（4C大楼）是中国环境保护部所在地之一。更确切的说是负责环境国际公约相关活动管理与监督的政府部门所在地。显而易见，意大利环境部与中国环境保护部之间的合作始于相关环境保护及国际公约的实施（从保护臭氧层的蒙特利尔议定书，到关于持久性有机污染物公约，以及联合国气候变化框架公约）。为上述目标而建造的履约大楼，得到了保护臭氧层蒙特利尔议定书多边基金的部分资助。毕竟，建筑行业在任何国家都是能源消耗的主要方面之一，因此，环境保护部在大楼的建设中将发挥重要作用。这个项目所呈现的挑战是要建造一个系统化的建筑，大楼除了用于提供办公场所外，还要特别注重节能，要广泛使用意大利的可再生材料、设备和系统，同时具有较高的审美和功能设计，并且，其性价比在中国市场上要具有竞争力。最后这一点尤其重要，因为我们希望这座大楼能够起到一个示范作用，证明用有限的成本实现一个高性能和高质量的生态可持续性建筑是可能的。在接下来的几页中将会对这些特点进行详细说明。关于这座建筑的外形，北京市规划委员会提出了进一步的挑战，他们希望大楼面朝二环（环绕城区中心的交通繁忙的马路）的这一面能够在外形以及颜色上表现出雄伟壮观的特点。建筑师马里奥•奥奇托运用其丰富的聪明才智，将这个外形上的要求与北立面气候保护方面的需要有机结合，设计了一个极为整洁和朴素的立面，在满足限制条件的基础上，通过加入某些建筑元素（如水平条窗和垂直且具有弧度的玻璃幕墙）又使该立面轻松了许多。

大楼立面上的弧形玻璃幕墙与呈弯曲形状装有玻璃幕墙的建筑左侧连接，很自然地到达后面的南立面，以明快的方式与后面的公共区域相连。人们可以从南面进入大楼，然后惊喜不断。照片上并没有准确显示出大楼内部的情况。由灯光艺术大师Ingo Maurer设计的两个如同“阳光吊灯”般的“照明机器”，就像两个光亮的梦幻体，照亮着大楼内的两个中庭以及大厅内令人愉悦的地面。我不知道这座建筑是否在将来可以供人们参观，但是它肯定值得一看。难以置信的是，真正让我感到快乐的是，从最初的准备阶段开始我就全程参与了这个项目。而最为重要的是，这个项目不仅实现了最初设定的目标，而且还完全按照“市场”水平成功地控制了成本。就像我在开头中所说的，这个建筑对我们来说具有示范意义。这个项目的最终结果非常令人满意，它使我们以及我们的中国同事们认识到，即使在一个小的范围内，我们也能够成功地在中国生态可持续发展原则及技术普及方面做出贡献，这座建筑的名字虽然短，4C，但它将对全球的环境保护工作做出巨大的贡献。

Massimo Martinelli特别顾问

The Ministry for the Environ-ment, Land and Sea of Italy (IMELS) and the Ministry of Environmental Protection of P.R. China (MEP) initiated coopera-tion program in environmental field in 2000. This program developed by cooperation with several Chinese institutions including Chinese Academy of Social Sciences (CASS), the Ministry of Science and Technology of the People’s Republic of China (MOST), the Ministry of Water Resources of the People’s Republic of China, State Forestry Administration, P.R. China, National Develop-ment and Reform Commission (NDRC), Beijing Municipal Go-vernment, Shanghai Municipal Government, Tianjin Municipal Government, Xi’an Municipal Government, Suzhou Municipal Government, Lanzhou Municipal Government, Urumqi Municipal Government, Tsinghua Universi-ty, Shanghai Jiaotong University and Tongji University. Under this program, up to now, 832 objective guidelines have been established for monitoring and management of environ-ment, enhancement of Chinese institution at national and local levels, protection and conser-vation of natural resources, ma-nagement of water resources, energy recovery of the waste, development of renewable energy and energy efficiency, sustainable urban planning, environmental protection in poorer areas, development of technologies and transport systems with low emission, sustainable agricultural develop-ment, protection of biodiversity and management of forests. These projects were determi-ned according to objectives and plans raised in UN conventions

and protocols in climate change, protection of ozone layer, protection of biodiversity, elimination of persistent organic chemicals and combating deser-tification. In particular, projects on energy efficiency, renewable energy, the energy recovery of the waste and forest management are designed to reach the emission quotas specified in the Clean Development Mechanism (CDM) of Kyoto Protocol. In order to involve more Italian companies in the cooperation program and make full use of the potential of our techno-logies, the Ministry for the Environment, Land and Sea of Italy (IMELS) entrusted Italian Trade Commission (ICE) Beijing Office to be responsible for the management of the cooperation program. The implementation of the pro-gram is assigned to an Italian-Chinese working team with two permanent offices in Beijing and Shanghai respectively, over 60 experts from the Ministry for the Environment, Land and Sea of Italy (IMELS), Chinese ministries and agencies, Italian and Chinese scientific research institutions and universities . For the Italian side, besides the Ministry for Environment, Land and Sea, the National Research Council of Italy (CNR), Uni-versity of Bologna, University of Pavia, University of Turin, University of Tuscia, University of Venice, Bocconi University, Venice International University, Foundation Mattei and the Interuniversity Consortium of Managerial Economics all parti-cipated in the program. Since 2001, the Ministry for the Environment, Land and Sea of Italy (IMELS) has co-

financed these projects with 170 million Euros through direct contributions and trust funds institutions set up in the World Bank and multilateral fund. Chinese institutes financed these projects with 40 million Euros in total. Italian companies supported the cooperation program with 25 million Euros. The United Nations Founda-tion, UN agencies – the united nations environment program-me (UNEP), the United Nations Development Programme (UNDP), the United Na-tions Industrial Development Organization (UNIDO), Global Environment Facility, the World Bank and the Multilateral Fund of the Montreal Protocol for the Protection of the Ozone Layer financed with 29 million Euros. Up to now, the program inclu-des projects with totally about 264 million Euros.In 2005, the Chinese gover-nment realized the value of co-operation with Italy and granted Mr. Corrado Clini, the Director General of the Ministry for the Environment, Land and Sea of Italy (IMELS) the International Scientific and Technological Award.

该计划的落实贯彻被委派给一个意中工作组，其在北京和上海有两个常驻地址，由超过了60名的来自意大利环境，领土与海洋部，中国各部和机构，以及意大利及中国的科研院所和大学的专家组成。对于意大利方面，除了环境，领土与海洋部外，意大利国家研究委员会（CNR)，波罗尼亚大学，帕维亚大学，都灵大学，图西亚大学，威尼斯大学，博科尼大学，威尼斯国际大学，马特艾基金会，管理经济学校际联盟也参与了该计划。从2001年至今，意大利环境，领土与海洋部通过直接捐助和借助设立在世界银行和多边基金的信托基金机构的作用共同资助了这些项目170,000,000欧元。中国机构对于这些项目的配备资金为40,000,000欧元，意大利企业对该合作计划支持了25,000,000欧元，联合国基金会，联合国机构-联合国环境规划署，联合国开发计划署，联合国工业发展组织，全球环境基金，世界银行和用于臭氧层保护的蒙特利尔议定书的多边基金共同筹资为29,000,000欧元该计划，到目前为止，共包括了大约有264,000,000欧元的项目。在2005年，中国政府认识到了与意大利合作的价值，向意大利环境，领土与海洋部司长，Corrado Clini先生，授予国际科学与技术奖。

意大利环境，领土与海洋部与中华人民共和国环境保护部于2000年起便开始了在环境领域的合作计划。这个计划通过和多个中国机构共同合作得以发展，在这些机构中有中国社会科学院(CASS)，中华人民共和国科学技术部(MOST)，国家水利部, 国家林业局, 中华人民共和国国家发展与改革委员会(NDRC), 北京市政府，上海市政府，天津市政府，西安市政府，苏州市政府，兰州市政府，乌鲁木齐市政府，清华大学，上海交通大学和同济大学。在这个计划范围内，至今已经发展制定了832个目标计划方针，这些方针都是有关于环境监测和管理，国家和地方级别的中国制度的加强，自然资源的保护与保存，水利资源的管理，废物的能源再利用，可再生能源和能源效率发展，可持续的城市规划，贫困地区的环境保护，低排放的技术和运输系统的发展，可持续农业发展，生物多样性的保护，森林管理。这些项目的确定是根据联合国有关气候变化，臭氧层的保护，生物多样性的保护，持久性有机化学物质的消除，以及防治荒漠化的斗争等方面的公约和议定书中所提出的目标和计划。特别是，有关能源效率，可再生能源，废物能源再利用，森林管理方面的项目旨在达到京都议定书的清洁发展机制（CDM）所规定的排放额度。为了能够让更多的意大利企业参与到这个合作计划中来，并充分利用我们技术的潜力，意大利环境，领土与海洋部委托给意大利对外贸易协会北京办事处对该合作计划管理的职责。

The life of a building commen-ces well before the building-site scrapers cut furrows into the land when actually building it. Through a lengthy process which will result in new volu-mes carving out a new urban skyline, the city will alter in its form and its functioning and then, over time, integrate them into its organism. The Environmental conven-tions Building/4c Building enriches the panorama of Beijing’s new architectures, to accommodate the seat of the Chinese Authority in charge of managing and supervi-sing activities relating to the implementation of Multilateral Environmental Agreements and the fight against the illegal traffic in hazardous chemical substances. The task, entrusted to mOa by the State Environmental

Protection Administration (SEPA), today MEP (Ministry of Environmental Protection of the P.R. China), in the framework of the Sino Italian Collaboration Program (SICP) on Environ-mental Protection between the Ministry of Environmental Protection of the P.R. China and the Italian Ministry for the Environment Land and Sea, has been to design a building around the idea of sustainability, understood in its complexity; that is to say, to relate the who-le project to a single concept which accommodates multiple meanings, including adaptabi-lity, recognizability, energy sustainability, accessibility, with the aim of creating a buil-ding which conforms to these principles while giving credence to local identities. The building will accommo-date an important centre of

international activities dedicated to environmental protection. mOa, Mario Occhiuto Architetture, developed the project with the collaboration of a team of Italian and Chinese experts, in particular F&M Engineering for the project and construction management and the structural and plant engineering, Prof. Federico Butera and Architetture Sostenibili. for the sustainable energy strategies and solutions, BIAD for the accommodation of the project to Chinese stan-dards and for executive deve-lopment. The realization of the building is the fruit of the deep-seated program of collaboration between the Italian Ministry for the Environment Land and Sea and his Chinese counterpart, the Ministry of Environmental Protection of the P.R. China (MEP). The building is regarded as among the milestones of

international cooperation for protection of the envi-ronment, not merely because the costs of creating it are being born by the Chinese Ministry for Environmental Protection and by the Multilateral Fund of the Montreal Protocol for the protection of the ozone layer, but also because it will be the very centre of operations of the Italo-Chinese collabo-rative program for environ-mental protection. This paper will chart the course of the Environmental Conventions Building/4C Building from the idea of a sustainable building to its actual com-pletion, by means of a design inspired by the complex nature of sustainability on all levels, from the definition of design concepts to the study of specific project details. The architectonic characteristics of

the Environmental Conventions Building/4C Building represent sustainability in its very essence, which has been the cornersto-ne of the technical and formal development of the work, and the architecture gives them recognizable aesthetic overto-nes. The aim of the project has been to create a comfortable and liveable work tailored to the requirements of the client and properly integrated into the surrounding context, in line with the character of a city and a country at the height of its technical development.Exploration of the aesthetic dimension, too, aims to repre-sent the concept of complex sustainability, so as to trace the whole work back to a design unity which is recognisable and strongly identifiable within the urban landscape of the capital.

inTRoduCTion导论


一座建筑的生命实际上在其开始动工建造之前就已经开始了。经过漫长的过程，新的建筑会形成一道新的城市轮廓，城市会因此而改变其形式及机能。随着时间的流逝，这些建筑会与城市融为一体。环境国际公约履约大楼丰富了北京新建筑的全景，它将成为中国负责履行多边环境协议政府机构的办公场所。受中国环境部（原国家环境保护总局）委托，意大利mOa建筑事务所负责该大楼的设计工作。大楼的设计应体现可持续

理念，遵循多项原则，包括可适应性、可识别性、可持续性、可达性等，并符合城市特点。意大利mOa建筑事务所的工作是在中意专家紧密合作下开展的。意大利F&M工程公司负责大楼的结构、机电设计及施工管理工作，Federico Butera教授与Sostenibili 建筑师负责提出可持续能源战略与解决方案，北京市建筑设计研究院（BIAD）负责按照中国规范开展深化设计工作。此建筑是意大利环境、领土与海洋部与中

国环境保护部开展深层次合作项目的成果之一。该建筑之所以被视为环境保护国际合作的里程碑，不仅仅是因为其建造费用由中国环境保护部与保护臭气层蒙特利尔议定书多边基金共同承担，也是因为该建筑为意大利-中国环境环境保护计划的运作中心。本书将从可持续性理念，设计理念，细节研究等多角度，对履约大楼建设过程进行全面介绍。履约大楼的建筑特征从本质上体现了可持续性理念，在此基础上赋予其建筑上的美学

意义。大楼的建筑目标是打造一个舒适、易于使用的建筑，符合业主的要求，并能融入周边环境，与城市和国家的特征相符。美学尺度的探究旨在体现综合可持续的原则，达到设计的完美统一，使大楼成为首都城市景观中的易于识别和辨认的建筑。

建筑设计

The Environmental Conventions Building/4C Building takes shape as a building that is sustainable in all senses of the term; it was born from a comprehensive assessment of the context and of its elements, which we at-tempt to evoke by pursuing the objectives of adaptability to the urban context and the environ-ment and recognizability in the civic landscape, thereby expres-sing our intent to valorise local identities. The building will be the workplace of hundreds of city dwellers, who should find it effortless to use, and it will be without sources of danger or fatigue. For this reason, the characteristics of accessibility have been closely examined in order to orient the design of internal spaces. The shape of the building, its position in the urban context, the correct arrangement of apertures and a proper use of materials permit maximi-zation of its energy efficiency, another fundamental principle of the design program. Each constituent part contributes to the generation of a dynamic, collaborative structure geared towards the building’s efficient bioclimatic behaviour and hence the maximum possible energy savings.

履约大楼全面体现了可持续建筑的含义。从一开始，我们就对大楼周边情况及其内部元素进行了全面评估，目的是使其适合城市背景，并具有明显的特点。大楼内将有数百人办公，要易于使用，无危险源，不会令人感到疲倦。出于这种动机，我们认真研究了通行方便性问题，以指导内部空间的设计。大楼的形状、位置、门窗以及建筑材料等的选择，都应最大限度地提高大楼的能源效率，这是设计中需考虑的另一个基本原则。大楼的任何组成部分都应有助于改善内部环境品质，并尽可能节能，形成一个活泼而相互默契的整体。

ThE dESign ConCEPTSgEnERAl PRinCiPlES设计概念总体原则



Moreover, a number of the building’s ingredients contribute to maximum energy savings and they also endow it with a specific formal character, so that it becomes an expression of sustainable architecture. • the composition of the

building plan, consisting of two wings: the western wing, compact in form and built around an interior rectan-gular courtyard, with the south façade curved high up, merging with the roofing; the eastern wing with its undula-ting design and the southern façade opened up by means of courtyards and folded back to merge completely with the east façade; this presents an external envelope characteri-zed by adaptability to climatic changes and a roofing package

此外，大楼的一些局部设计十分有助于节能，体现了大楼的可持续性。•大楼平面由东、西两个组团构成：西区紧密围绕一个内部中庭设计，其南立面弧形顶部收于屋面；东区呈弯曲形状，其南立面通过半中庭对外开放，并向后折拢，与东立面合为一体；这种外围护结构能适应气候的变化，而屋面的设计有助于内部的自然采光和节能。•大楼内有两个内部中庭，外部楼体也有一个面向南面的半中庭，将南立面有机分割，使之与后英房胡同居民区产生视觉上的联系。中庭的设计具有典型的胡同特色，在西方建筑中也有许多类似实例。中庭有利于自然通风和照明，对大楼内的小气候具有辅助调节作用。

which contributes towards internal lighting and the supply of energy.

• the 2 internal courtyards and the external semi-courtyard, which produces a fissure in the body of the building and opens it out towards the south, thereby fragmenting the façade and placing it in a visual and formal relationship with the residential quarters of Houyingfang hutong”; the courtyards - a reinter-pretation of a typological scheme typical of the city of the hutongs as well as of so many instances of western architecture, permit the direct ventilation and illumination of all the work areas and aid the regulation of the building’s microclimate.

Regarding the relationship with the context, a number of stra-tegic choices were made with a view to pursuing the objectives of adaptability to the environ-ment and energy efficiency: • the closure to the north, ari-

sing from the need to screen the building from the large road network, to protect it from the cold winter winds blowing from the north and north-west, and from the

need - expressed by the client - to confer an element of solemnity to this front;

• the aperture to the south, south-east, which permits a direct relationship with the residential quarters as well as the maximum possible surface area for natural vetilation and illumination, to exploit solar radiation for heating in winter and natural ventilation in the summer.

•南向、东南向的门窗：可以和住宅小区有直接联系，并最大限度地利用自然通风和自然光照明，冬季利用阳光照射取暖，夏季则用来自然通风。

在考虑与周边环境的关系方面，为保证大楼与环境协调并提高能效，我们做出了一些战略性选择：

•北向封闭：使大楼与交通干道相对隔离，并阻挡冬季来自北方和西北的寒风，同时根据业主要求，大楼北面要体现出庄重和严肃的特性。

从气候角度而言，北面存在一些不利因素，比如，没有阳光直射，冬季寒风凛冽。不过，南面有一些有利条件，光照充足，利于自然照明，冬季节省空调。从设计初稿开始，气候特点就提示我们大楼要朝北封闭，朝南通透。此外，我们对大楼的日照角度进行了研究。我们模拟了毗邻建筑产生的阴影和每个立面的日照水平，目的是找到围护

From the climatic point of view, there are a number of disadvan-tageous elements to the north such as the absence of direct insolation and the presence of cold winter winds. The south side of the building, on the other hand, is more favourably exposed, both due to the direct insolation which is beneficial for natural light and, in the winter, for air-conditioning, and due to the existence of cool winds during the summer. From the first project draft, the climatic features (as well as the town-planning conditions) have argued in favour of closing the building to the north and seeking greater permeability to the south.

The shadows produced by the adjacent buildings and the insolation level of the individual façades were simulated, with a view to optimization of the envelope solutions. From these simulations, it was possible to establish that the southern façade receives full insolation all year round, as does the western façade in the afternoon, while the eastern façade remains in shade for most of the time, except for the higher floors which for therefore require a diversified treatment.

履约大楼，一座可持续的建筑



In particular, the project evolved around the following points: • the definition of façades and of materials; • the role of courtyards for energy optimization of the building; • the definition of the functional and distribution layout of the building; • the optimization of plant engineering systems; • analysis of the sections of the project, of the horizontal and vertical façade intersection points. A multiplicity of theories have been examined for each of these points, right up to the working out of the definitive solution.

履约大楼应成为一座可持续建筑，为实现这一目标，必须对一系列问题进行深入研究，特别是以下几个方面：

• 大楼的立面形式和材料；• 中庭的节能作用；• 大楼的功能与分区；• 机电设备的优化；• 对剖面以及立面衔接点的分析。

对于上述几个方面，我们研究了多种设想，直至拟定最终解决方案。

北立面方案始终是大楼设计中的一个关键问题。从某种意义上讲，履约大楼的北立面代表着大楼的形象，它应使人能迅速直接地看出大楼的地位、身份和用途。采用严肃而庄重的结构形式，可标示此建筑是一座政府办公性质的大楼，更重

From the first phases of the project, the formal definition of the northern façade has had a key role for the develop-ment of the entire building. The northern façade of the Environmental Conventions Building/4C Building represents, in a sense, its calling card, and

EnviRonMEnTAl ConvEnTionS Building/4C Building, A SuSTAinABlE BuildingFAçAdES And MATERiAlS4C 大楼，一座可持续发展的建筑物立面和材料

was given the task of “presen-ting” the building by giving a swift and direct indication of its role, identity and objectives. The governmental function of the building made it necessary to develop the façade in such a way as to announce its official status, using a formally rigid and

monumental structure; above all, the particular designation of use assigned to 4C by the Ministry for the Environment suggested the possibility of making the building’s emphasis on environmental issues visible from the outside.

要的是，履约大楼是环保部的一座办公楼，应有明显的特点用以强调环境保护方面的特征。


履约大楼也是构成北京新面貌的一个组成部分。近年来，北京正经历着经济腾飞以及对未来史无前例的憧憬，许多建筑设计也都采用了新的材料和新的技术。对于履约大楼这座新的建筑，在确定其立面（特别是北立面）的方案时，应综合考虑这些因素。

The Environmental Conventions Building/4C Building also counts among the buildings which are to be the new face of Beijing, a city which in recent years has undergone an economic acceleration and an unprece-dented projection towards the future, experimenting with architectural designs with novel combinations of materials and technologies. The choice of how to develop the façades of the new building arose from these considerations, particu-larly the northern façade, so that these various issues were combined with the opportunity to valorise the technical and material aspects intrinsic to local identities.


crowned by the lighting project for the building, which will tran-sform the apertures into sharp slices of light, accentuating the expressive charge of the façade during the nighttimes.The grid framework is inter-rupted and rendered dynamic by the presence of large-scale elements, two double-height loggias, a glazed incision running vertically around the whole building – announcing the presence of a gallery within it – a cantilever roof marking the connection of the stone façade to the glazed double-height volume. These elements have been devised also in accordance with a perceptual logic, in relation to the setting of the building in the locality of a high-speed traffic

axis. it was therefore necessary to develop a vast structure, to make the building recognizable even to someone travelling at speed down Deshengmen West Avenue. In the same way, the design of the other façades was oriented to the maximization of light and energy and to seeking out volumetric and chromatic relationships with the context. Thus, the northern façade is more compact, material, introverted in the dimensions and form of its openings, which express a relation to the ex-ternal context that is limited to the creation of windows, taking into account the necessity for protection from the cold winter winds.

nortHFor the north façade, the project’s evolution traversed complex phases: the presence of a high-speed traffic axis and of cold winter winds enabled us to incorporate an element of dynamism which constitu-ted the nucleus around which various formal variations were subsequently developed. The final solution for the façade of the Environmental Conventions Building/4C Building which faces towards Deshengmen West Avenue was devised as a large parallelepipe-don, suspended over a glazed double-height volume, planned by an articulation of large stone slabs, hollowed with horizontal and vertical cuts revealing their apertures. The structure will be


北立面

北立面的设计经历了比较复杂的过程。大楼北面是交通干线，而且冬季北风凛冽，围绕对这些核心因素的考虑，我们曾提出了多种不同的方案。在履约大楼立面的最终方案中，北立面由一个方正的形状构成，下部是两层楼高的玻璃幕墙，其上是较大尺寸的石材板，有横向和纵向的开缝。立面上布置了景观照明，使其在夜晚具有较强的表现力。网格状的立面中间镶嵌了一些大型元素，其中包括两个双层楼高的露台、一个竖向到顶的玻璃景观墙，以及连接底部玻璃与上部石材的雨棚。

这些元素的设计也考虑了大楼位于交通干道旁边这一因素，采用大尺寸立面结构能够使大楼易于辨识，即使是驾车快速通过德胜门西大街的时候，也能方便辨认。同样，基于照明和节能方面的考虑，以及大楼体型和颜色与周边协调等方面的因素，北立面窗户的大小及形式较为紧凑、实用和内敛，较小的开窗率是为阻挡冬季寒冷的北风。


EASt And wEStThe two lateral façades mediate between the different situa-tions in a somewhat different manner, with a mixed use of facing materials – stone slabs and alucobond panels – which respectively characterize the northern and southern façades. Suitable screening systems are positioned on the southern, ea-stern and western façades with a view to avoiding undesirable effects such as overheating and glare during the summer: horizontal overhangs, whose dimensions are a function of the form and dimensions of the windows, optimize the supply of solar radiation by curbing the use of artificial illumination and maintaining elevated levels of visual comfort.

东、西立面这两个立面的设计考虑了不同的情况，形式也略有不同，立面中混合使用了南、北立面的典型材料，包括阿鲁克邦铝板和石材板。东、南、西立面使用了遮阳系统，目的是在夏季防止曝晒和眩光效应，水平遮阳板的尺寸取决于窗户的形式和大小，其作用是尽量减少人工照明，同时保证较高的视觉舒适度。

The functional and distribution organization of the Environmen-tal Conventions Building/4C Building developed from earliest formulations around two leading ideas:• the presence of internal

courtyards as the backbone of the building;

• the permeability of the system on the north-south axis. The two principles are closely linked with the idea of acces-sibility, a founding element of complex sustainability; a di-stribution organization which is characterized by brightness and ease of movement along routes becomes more acces-sible and recognizable for its users. The system of court-yards plays a key role in the perception of the building and

in its vertical formation, be-cause it creates an immediate point of reference for anyone passing through the corridors which run along the courtyar-ds themselves. All the offices and the rooms are therefore immediately identifiable, and from one level of the building to the other, a system of visual targets is created which enables each area to be loca-ted easily, in addition to the presence of an internal sign system. The two distribution rings which run around the courtyards are also linked by a central connecting system. This system, which at ground level gives total permeability from the north entrance to the south entrance across the hall, is repeated on all levels of

the building, and it characte-rizes the common areas of the building as well as those designated for delegations. The central position of the system is announced by a series of features which are fundamental for the system of orientation:

• the central stairway-elevator block, placed in the curvilinear volume at the centre of the south façade;

• the open stairway, linear in formation, which connects all building levels, tangential to the north gallery;

• the double-height hall at the heart of the distribution system, utilizable as a meeting point or relaxation area;

• the crush rooms, located on the north gallery and announ-

ced by a broad, vertical glazed surface, which visually connect the interior and exterior of the building and permit the establishment of an additional relaxation area.

The distribution system aims to communicate the idea of an organism which is bright, transparent, open and integra-ted into the life of the city, as well as being attentive to the needs of its potential users. The luminosity of the distribution system and the modularity of the structure also allow for flexibility in capturing any functional and dimensional variations within it.The functional layout of the Environmental Conventions Building/4C Building allows spaces on the 1st and

2nd level to be opened out to external users; in particular, the bank and the cafeteria are located on the 2nd level mainly accommodates areas for confe-rences and meeting rooms. The levels above this will be ear-marked for administrative use, with a prevalence of offices and open spaces. The 9th level will accommodate areas open for use by the whole building, such as the library and gymnasium, in addition to the whole executive area (vip rooms).The canteen with its associated service areas will be located on the first basement level, in addition to a parking area which is to occupy almost the whole area of the second basement level.


履约大楼的功能与通行布局主要围绕以下两个原则进行设计：• 两个中庭构成了大楼的核心；• 南、北轴线上的贯通性。上述两个原则都与通行的方便性密切相关，而这是实现可持续性理念的一个基本要素。明亮且方便通行的走道能使用户更容易地到达和辨别目的地。中庭对于人们感知方位起着关键作用，当人们沿中庭周边走廊行走时，中庭是一个很直观的参照体，可以使人即刻分辨出办公室或其他房间的位置。除内部标识系统外，设立视觉上的参照体系，也能使人方便地找到任何地方。围绕中庭构成的两个环形通道由大楼中部的贯通系统相连。首层南、北两个入口之间完全贯通，这种方式也体现在其他楼层，构成

了大楼的公共区域。中部贯通系统还包括如下几个方面：• 大楼中部的楼梯和电梯间，位于南立面中部的曲线体中；• 北面开敞的直线型楼梯，可通达任何楼层，与北走廊相连；• 中心区域的双层挑空大厅，可用于集会或休闲；• 北走廊内的休息室，朝外有宽大的垂直玻璃窗，将大楼内部与外部视觉相连，也可作为休闲区域使用。大楼内部通行系统设计的目标是保证其明亮、通透、开敞，与城市生活相融，同时也要考虑潜在用户的需求。通行系统的明亮程度及其结构上的模块化也允许其功能和尺寸上的变化具有灵活性。在功能布局方面，履约大楼的首层和二层为对外开放区，银行与咖啡厅可位于大楼首层，

而二楼主要提供会议间。三层及以上楼层为办公区，由办公室与开放空间组成。九层有图书阅览室和健身房，另外还有贵宾办公室。食堂及其相关服务区位于地下一层。另外，还有停车场，停车场几乎占据了地下二层的整个区域。

4C 大楼，一座可持续发展的建筑物室内设计

The interiors of 4C have been designed according to a concept of general harmony in terms of form as well as materials used. From time to time the spaces have been conceived in accor-dance with functional, safety and aesthetic requirements.The ground floor, which is of vital importance as it introduces the building and welcomes the public, opens up on a large spa-ce paved with crushed marble tiles, travertine-lined columns and well-defined distributive nodes/distribution ring.The two courts extend all the way to the top of the building . In the hall and the courts, two giant statues and several works of art by Maurizio Orrico adorn the spaces. The vertical space of the building is accentuated by a

three-storey high atrium, cove-red completely with travertine.The solemn elegance of the entrance is transferred to the main staircase, which connects all the floors with its wooden handrails and marble steps. The information desk rests against the curved wall, which is also covered in travertine, continuing on towards the gore area which penetrates the space creating a dialogue between the internal and external areas.A few works of art, in different positions, complete the har-mony between the spaces.The second floor, which is also representative, has a crushed marble floor with a design that has been created for the building, and it hosts the confe-

rence rooms as well as various waiting rooms for VIPs. The floors in light-coloured crushed marble can again be found on all storeys, in the corridors and in the crush rooms. These rest and relaxation halls, which are present on all floors, offer comfortable seating with views towards the outside.


履约大楼室内设计原则是保证装修形式以及装修材料的和谐，空间布置上要根据功能、安全和审美等方面综合考虑。首层的视觉效果非常重要，因为它可以展示大楼形象和迎接公众的到访。宽敞的大堂由铺装了人造大理石地砖的通道、纹理清晰的洞石柱面，以及精心设计的通行节点和环路组成。两个中庭一直延伸至大楼顶部。首层的三层挑空中厅全部采用洞石墙面。庄重典雅的入口与主要楼梯间相连，楼梯通往各个楼层，楼梯扶手采用木材装饰，楼梯踏板由大理石铺装。大堂前台背靠弧形墙体，墙面同样采用洞石装饰，洞石墙面将大楼内外区域有机相连。点缀各处的艺术品更加增添了空间的和谐氛围。二层同样具有很强的代表性，地面仍然采用人造大理石铺装，楼层内分布有各种会议用房以及贵宾接待房间。明快的人造大理石也用于其他楼层的走廊和休息厅。各楼层的休息厅提供舒适的座位，可供人们欣赏楼外景致。


From the third to the ninth floor we find offices of different dimensions and sizes, alternating between open spaces and ma-nagement offices. The ninth and last floor is dedicated to VIP spaces, the gym and the library. The library ceiling is completely covered in wood and follows the curvature of the roof, crea-ting a welcoming atmosphere in which large wooden bookcases and tables adorn the room; the multicoloured crushed marble floor covers the space, remin-ding one of Pompeian mosaics.The north-facing offices have louver windows to reduce heat loss but, to compensate for this, additional light is provided by the glass walls on the corridor, which allow for the diffusion of light originating from the internal courts.

三层至九层布置了不同大小的办公室，开放式空间和办公室错落有致。九层布置了贵宾办公室、健身房和图书阅览室。阅览室天花板使用木质材料沿弧形屋顶进行装饰，大型木质书柜和阅览桌为房间营造出一种宽松的气氛；室内地面由五颜六色的人造大理石进行铺装，让人联想到庞贝式的马赛克。北面办公室开启窗面积不大，以降低热量损失，不过，走廊处的玻璃墙可以将中庭的光线漫射进来，可提供额外的自然光照。


相反，大楼南侧各办公室均安装了大窗口，以及可提高光线间接漫射的遮阳板；而走廊墙面采用烤釉玻璃进行装饰。二层以及六至九层的家具采用专门定做的家具。这些桌子均由拉丝不锈钢、有机玻璃和木饰面构成，采用模块式组合系统，从而确保特定空间范围内的更大灵活性。在办公室内部，作为书架的大型木质墙壁与大型办公桌浑然一体，桌面的风格也体现出这座大楼的外形设计。

By contrast, on the south side, the offices have large window openings and light shelves to promote the indirect diffusion of light, while the corridor walls, made of bricks, are lined with lacquered glass.The furniture of the second and sixth to ninth floors is tailor-made. The tables, conceived as a modular assembly system to guarantee greater flexibility within the spaces, are made of brushed steel, Plexiglas and have wood finishings. In the mana-gement offices, large wooden walls used as bookshelves blend with large desks, the worktops of which recall the formal desi-gn of the building.


照明设计由意大利古奇尼公司提供，通过办公室中的合理配光来增强内部空间的光线，同时，还考虑到能耗问题。在外面，北立面的照明是由建筑师弗兰切斯卡•斯托拉罗构思设计而成的，将空间和物体相结合，和谐地增强了大楼的建筑表现。由于使用了能耗低、发光效率高和寿命长的灯泡，尤其是LED，体现出了对能源可持续性方面的重视。

The lighting design, provided by iGuzzini, allows the internal spaces to be enhanced through the correct distribution of light in the offices while also taking energy consumption into account. On the outside, the lighting of the north face as conceived by the architect Fran-cesca Storaro combines space and objects to harmoniously enhance the building’s architec-ture. Energy sustainability has also been respected thanks to the use of low-energy bulbs with high luminous efficiency and long life, in particular LEDs.

工程设计

Developed in close collabora-tion with F&M engineering, and also with the help of Professor Federico Butera of the Milan Polytechnic and Architetture Sostenibili and BIAD, the design of the façades of the Environ-mental Conventions Building/4C Building gave complete control over the work, closely intersec-ting the design phase with the building phase. All the materials are completely recyclable and of high thermal efficiency.

大楼的幕墙设计是与意大利F&M工程公司紧密合作完成的，也得到了米兰工艺学院Federico Butera教授与Architetture Sostenibili，以及北京市建筑设计研究院的帮助。所有材料都是可循环利用的，并且具有很高的热工性能。

结构

大楼平面相当规整，大部分为钢结构，柱距为8米，楼板由压型钢板与钢筋混凝土板构成。大楼结构方案由一个三维多层框架构成，此框架钉入地基，并连续用刚性板壳结构将每一层框架连接，从而将水平力引向管状混凝土立轴中，由此而引向地基。因此，通过框架柱传递的荷重主要来自垂直方向，水平荷载较小。

STRuCTuRES

The plan of the building is quite regular, and the majority of the structure is steel framed with frames at approximately 8.00 m centres supporting a corruga-ted steel sheet with reinforced concrete slab.The structural concept con-sists of a global 3-dimensional multilevel frame, pinned to the foundation level, continuously connected at every floor by a rigid structural shell, which acts in order to lead the horizontal forces into the tubolar concrete vertical shafts, and from here to the foundations.Consequently, the loads tran-sferred throughby the frames’ columns are mainly vertical, with small horizontal loads.


而且，较轻的钢结构比较重的混凝土结构抗震能力要强。另外，工期短也是采用钢结构的原因之一。与混凝土不同的是，钢材还可以回收再利用，是生态友好型的材料。最终，大楼采用的主要结构材料包括：• 首层至屋面的楼板采用压型钢板与钢筋混凝土板；• 首层至屋面的横梁采用工字钢；

More over, a light-weight steel structure better reacts to the important seismic dynamic load then a heavy concrete struc-ture. The short available time to get the building completed is also another consideration which suggested to adopt a steel structure and finally, differently from concrete, steel is a complete recyclable and eco-friendly material.

Consequently, the main structu-ral elements of the building are:• Corrugated steel sheet with

reinforced concrete slab for the floors from level+1 to the roof level;

• Steel double T sections for the beams from level+1 to the roof level;

• Steel tube sections for the columns from level+1 to the roof level;

• Reinforced concrete slabs, beams and columns for the underground levels;

• Reinforced concrete slab and beams for the foundations.

The lift shafts and the staircases are made by in cast reinforced concrete and are destined to react to the horizontal loads on the building.

• 首层至屋面的立柱采用圆柱形钢管；• 地下楼层采用钢筋混凝土楼板、钢筋混凝土梁与钢筋混凝土柱；• 地基采用钢筋混凝土板与钢筋混凝土梁。电梯井与楼梯间由钢筋混凝土浇筑而成，需要承受建筑物的水平荷载。


The basic design parameters, according to the Chinese codes are:• Basic wind pressure:

Wo=0.45KN/m2• Floor roughness category:

Class C• Basic snow pressure: 0.40KN/m2• Intensity for floor seismic-resistance: Level 8• Earthquake protection class:

It has been verified that no rele-vant limit state is exceeded. All relevant design situations and load cases have be considered.It has been always considered the most unfavourable condi-tion proposed by the Chinese codes.

按照中国规范，大楼的基本设计参数为：• 基本风压：Wo=0.45KN/m2• 地面粗糙度类别：第3级• 基本雪压：0.40KN/m2• 房屋抗震烈度: 8级• 防震级别：C级• 基本地震动加速度：0.2g• 设计地震群：第1群• 建筑地地质类型：三级• 工地冻深标准: 0.8m• 地下水位深度：-15m此建筑的安全等级为II级，设计使用寿命为50年，并且建筑抗震级别为C类。已核实未超出任何相关的极限状态。并且，考虑了所有相关的设计状态与荷载情形。同时，我们始终考虑了中国法规所规定的最不利的情形。

EnviRonMEnTAl ConvEnTionS Building/4CBuilding 67FAçAdES幕墙

履约大楼的幕墙设计是意大利工程师小组研究的一个专项课题。在节点设计中通过采用外保温层和取消导热连接部件等措施，提高了幕墙的保温性能。幕墙始终与钢结构保持一定距离，防止热量散失，并使之保持相对独立。对于石材幕墙，采用略微隔开

The curtain wall of the Environ-mental Conventions Building/4C Building was a specific subject of the research made by the italian engineers team. The design of the sections has permitted an increased thermal efficiency of the façades, by arranging an insulation packet outside the wall and finishing elements capable of eliminating any thermal joints. The façade is consistently placed at a distance from the steel structure in order to avoid thermal disper-sion and to allow for a certain

formal independence.Where the façades are covered by slabs of stone material, fastening with a slightly spaced steel section increases the ther-mal efficiency of the envelope, which functions as a ventilated façade. Even in the case of windows high up, the creation of a spandrel fascia, suitably insulated and glazed on the outside, will help limit thermal dispersion, while maintaining a uniform look for the building.

的钢制构件进行固定，起到通风幕墙的作用，可提高幕墙的隔热效率。甚至对于高高的窗户，只要窗户的过梁横带具有一定的绝热性能，并且外部经过抛光，在保持建筑外观一致的同时，也有助于防止热散失。


北立面由石材与可重复利用的金属制成的通风幕墙以及隔热效率较高的条窗构成；而其他几个立面则由幕墙以及用于控制太阳辐射和改善自然照明的遮阳板构成。具体包括干挂石材的通风幕墙、玻璃幕墙及遮阳部件。幕墙结构通过预埋于混凝土楼板边缘的支架及哈芬槽与建筑主体相连。玻璃幕墙由透明玻璃

和层间部分组成，具有较高的隔热效率和热工性能。所有透明玻璃均为DUG LOW E玻璃，其导热系数为1.2 W/SqMK。非透明部分由200毫米厚的石棉层与200毫米厚的轻质混凝土砌块加以隔热，其导热系数不大于0.4 W/SqMK。

对于一些细部元素，如北立面的雨棚，也进行了处理，以便

The north façade is made by a ventilated façade of stone and recyclable metal, with high efficiency strip windows; on the other sides, the façades are composed by curtain walls, brise soleil and light shelfs, in order to control solar radiation and to improve natural lighting.The specific tender included the

ventilated façade, with the stone cladding, the glass façades and the sun screen elements. The curtain wall structures are con-nected to the building structure by means of brackets and halfen profiles cast inside the concrete edge of the slabs. The curtain wall system made by glass and spandrel areas guarantees high

efficiency and performances.All the glazed areas are made by DGU low E, with a thermal conductivity of 1,2 W/sqmK.The opaque areas are well in-sulated by a 200 mm rockwool layer and 200 mm light weight concrete blocks, with a thermal conductivity not exceeding 0,4 W/sqmK.


Precision elements, such as the horizontal fascia connecting the cantilever roof onto the north façade, were handled so as to control the down flow of rain, ensuring the formal cleanness of the architectonic dimension. On the internal side of the glazing there is a parapet brick wall to better keeping the internal temperature and

the energy of the building. All double glazing units included in the glass façades will be made in accordance with precise ther-mal calculations. The finishing surfaces of the curtain wall included aluminum sheets, stone panels and glass panels.All visible floors on the double-height spaces are finished with a steel casing (carter) which

ensures architectonic continuity with windows and false ceilings. Even the light-shelves, from their functional aim to maximi-ze the supply of natural light to the interior of the offices and also thereby to cut down on glare, becomes an opportunity for formal definition of the façade, marking the rhythm with horizontal articulations.

控制雨水的下流，从而保证了建筑外观的清洁。玻璃窗的内侧有砖体护墙，可以较好地保持室内温度与建筑物的能量。玻璃幕墙中的所有双层玻璃都是在精确的热工计算基础上加以制造。幕墙装饰面材料包括铝板、石材与玻璃板。

所有两层高空间的地板都装饰有钢套，钢套可保证地板与窗

户和吊顶在建筑上的连续性。甚至是遮阳板，虽然其功能在于实现自然光照明，同时减少眩光，但也是幕墙的一部分，也应起到表现幕墙韵律的一个元素。


M&E SYSTEMS机电系统

大楼中采用各类设备以及技术（建筑体型、幕墙设计、装饰材料以及安装的所有高性能部件）能够显著降低能耗，从而减少CO2的排放。机电设计计算表明，采用的冷梁、太阳能板、光伏发电系统等元素，提高了大楼能源效率。

空调系统也是根据节能标准以及运行成本控制等因素进行设计的。大楼冬季采用市政热力供暖，而制冷采用的是冷水机组。

The mixture of the types of plants adopted and the technological systems (shape of the building, orientation of the façades, materials of the finishing and high performances of all installed components on the building) allow a remarka-ble reduction of the energy consumption and therefore of the CO2 emissions.

Design elements such as ac-tive beams, solar panels, pho-tovoltaic system, integrated into the general philosophy of the design, make optimal the energy performances, as demonstrated by the plants’ design calculations.The air conditioning system also responds to criteria of

energy efficiency and control of production and operation costs: district heating system have in fact been selected for the wintertime, while cold air is obtained through the use of water chillers.


The designed chillers are particularly suitable to be used in medium/large size air conditioning or process cooling. The units are very compact and all their components are easily accessible for maintenance and control. The active beam type is also particularly suitable for the Environmental Conventions Building/4C Building.Its main advantages are flexi-bility, capability of performing high heating/cooling rates, easy of maintenance, reasonable cost, as here below described:• Flexibility: no terminal units

at floor level and modular distribution at ceiling level.

This is particularly suited for open spaces offices, but also it allows easy change of par-titions for adapting small and medium office rooms to chan-ging requirements; the beams can be individually controlled so that they can compensate different loads such as along façades or in the inner part of the building;

• High heating/cooling rates: the models with primary air (radiant-inductive) or the inductive models can supply cooling loads up to 100 W per square meter of floor area, which is suitable for both the internal loads due to computers, copying machines etc. and external heat gains (if well controlled by the building envelope as here proposed);

选用的制冷机组特别适用于中小型的空调系统，机组非常紧凑，同时所有部件易于检修和控制。冷梁也特别适合履约大楼使用。它的主要优势在于其使用灵活、制冷制热效率高、维修简便、价格合理，具体如下：

• 灵活性：没有接近地面的终端单元，也没有安装于天花板的组件。这尤其适于开间办公室，如果要求变化，可以简单地改变分区以适用于小型办公室和中型办公室；冷梁可以进行单独控制，以补偿不同的负荷，比如沿外墙附近的外区，或靠近大楼内区等。

• 较高的制热/制冷效率：带有新风诱导装置的冷梁，其提供的制冷负荷高达每平方米100W，这既适合于内部负荷（来自电子计算机、复印机等），也适合于外部负荷（如果维护结构能够很好控制隔热性能的话）。


• Easy of maintenance: the ab-sence of fans, differently from fan-coils, reduces the need and the cost of maintenance; the absence of moving parts results also in low noise level;

• Cost: the cost of a chilled beam system with primary air can be considered compa-rable with the cost of other primary air systems and lower than the cost of other sy-stems of similar performances, like VAV (Variable Air Volume) systems.

• 维修简便：不同于风机盘管，冷梁中没有风机，减少了维修次数以及维修成本；由于没有运动部件，因此噪音很小。

• 价格：带有新风装置的冷梁，其价格与其他新风系统相当，但是比具有同样功能的其他系统（比如变风量系统）价格低。

hElioSTATiC SYSTEM太阳光反射系统

The efficient planning of plant engineering systems is neces-sary to maximize the contri-bution of climatic and natural elements – obtained thanks to the correct architectural design – in order to ensure eco-compatible functioning. For the Environmental Conventions Building/4C Building, the natural light utilization systems – light shelf, orientable heliostats, internal courtyards – work in combination with the special low-energy artificial illumina-tion system, which is operated through a system of photo sensors which allows the level of natural light present to be compensated by a level of artificial light that is strictly necessary, in order to ensure optimal illumination consistent with the lowest possible energy consumption.On top of the roof there are glazed skylights covering the atriums, which will allow sunlight, caught by the movable heliostats and reflected by the secondary mirrors, to enter the building and cross at least 9 floors vertically. The Heliostats shall be mounted on a pedestal mounted on top of the roof. The Heliostat-mirrors are tracking the path of the sun by means of a high-precision control unit. Once the sunrays have been caught by the Helio-stat, they are projected onto secondary mirrors facing the Heliostats.

为最大限度地利用气候和自然条件，达到生态节能的目的，必须对大楼的机电系统进行有效设计。履约大楼中太阳光利用系统，如遮阳板、追光镜、内部中庭等，与经特殊设计的低能耗人工照明系统配合使用，可营造一个最佳的照明环境，并使能耗降到最低。人工照明系统通过照度感应器可补偿自然光的不足。大楼屋面在中庭处设有玻璃天窗。自动追光镜可将太阳光反射到次级镜片上，然后透过玻璃天窗通过中庭穿过9层楼的高度将阳光投射到楼内。追光镜通过屋面基础固定，通过高精密的控制装置，追光镜可自动跟踪太阳运动轨迹，可将聚集到的光线投射到面对中庭的次级镜片。


These are mounted on a steel-sub-construction placed on top of the roof. The sunlight can furthermore be distributed by mobiles called chandeliers. The-se chandeliers are composed by flat prismatic plates 300x300x4 mm, supporting tubes, stainless steel ropes and balanciers. It is assumed to have one chan-delier per atrium. Automatic electronic control system for two Heliostats includes the control functions of the meri-dian parallel, time difference to

这些设备安装在房顶的钢结构支架上。另外，投射到中庭的阳光可由吊装在中庭屋面的枝状挂件散射到各个方向。这种枝状挂件由300x300x4 MM平整的棱镜片、支撑管、不锈钢绳索和支架组成。每个中庭都有一个枝状挂件。追光系统的自动控制装置能够控制经纬度、与格林尼治标准时间的时差、日期、当地时间等。根据这些数据，控制器会自动计算出与

Greenwich Mean Time, co-ordi-nation of goals, date, local time etc. On the basis of this data, the control unit automatically calculates the exact positions for the Heliostat in accordan-ce to the position of the sun. Thus the incoming sunlight is reflected into the desired direc-tion means onto the secondary mirror in such a way that as much sunlight hits the reflecting mirror and consequently the target.

太阳方位相对应的追光镜位置。因此，引入的阳光按照预期的方向反射到次级镜子，次级镜子再将阳光反射到目标物体。


The basic system consists of:• microprocessor control• interface and power unit• included modem connection

with link to the manufactures head-office. Due to this mo-dem a first aid can be easily done if necessary.

基本系统由以下几个方面组成：• 微处理器控制系统• 操作界面和电源• 连接生产商总部的调制解调器。必要时，可通过调制解调器方便地处理紧急情况。

PhoTovolTAiC SYSTEM光电系统

The photovoltaic system is inserted on part of the curtain wall on the curved south side of the building. The “photovoltaic panels” system is made accor-ding to Italian high-technology: an Italian company, specialized in the design, distribution, installation and maintenance of the “photovoltaic system”, is the supplier. The installation is integrated into the grid of the south façade: the system is supported by painted aluminum extruded profiles with typical module subdivision.

光电系统镶嵌在大楼南面的弧形幕墙上，构成幕墙的一部分。“光电板”系统运用了意大利的高新技术：光电板的供应商是一家专门从事“光电系统”设计、配置、安装和养护的意大利公司。



The panel orientation shall match with the curved shape of the façade, varying from 0° to 73° from the horizontal position. There are 16x14=224 panels totally, and the total power output is about 20 kW. The PV panels shall be assembled on aluminum frames on the whole perimeter and cabled. The PV panels, for esthetical result, shall be mono crystalline silicon technology. The grid connected system shall foresee the minimization of the power losses along cabling with distributed DC/AC converting system. The inverters and the junction boxes shall be located in the dedicated room at roof level. The system shall be con-nected to the building network, from the roof level down to the basement’s switch room.Measuring devices shall count the energy produced and record the data for the analysis of the system, while protecting devices shall permit a safe maintenance on the lines and protect the system’s integrity.

光电板的方向必须根据墙面的弧形形状确定，即光电板与水平面的角度在0°到73°之间变化。光电板共有16x14=224块，供电能力大约为20 kW。光电板必须装配在铝制结构上，并通过电缆连接。为了美观，光电板采用单晶硅技术。连接电力连接系统应确保经过交直流转换后电能在电缆的损耗最小。位于屋面的光电系统与地下室的配电室相连，并入大楼电网。计量装置可计量并记录发电量用于数据分析，另外，保护装置必须保证系统维修的安全性，并且保护系统的完整性。

能源效率

The aim of this work is to evaluate the average energy consumption of a typical year for the Environmental Conven-tions Building/4C Building.A building simulation with the software DIGITHON has been carried out. This model has been tested in the frame of CEN TC 89 WG 5 and is one of the models used as reference for the guideline on thermal models for simulating buildings in order to predict thermal loads and temperature.When simulating a building equipped with HVAC systems, it is possible to predict some typical behaviour of occupants. Sometimes in practice people behave in different way, there-fore results from simulations seem to be not really accurate when compared to real energy consumptions. Moreover energy consumptions are not measured with accuracy and it is very difficult to compare measurements and simulations. Nevertheless simulations give a very good idea on the problems of buildings and therefore they can be assumed as reference for the evaluation of energy performance of buildings.A particular item when simulating office buildings is

the presence of people inside. The amount of people in the working place differ over the day, as it has been observed in some recent works. It is also difficult to predict the typical user behaviour and interactions between persons and different equipment used for usual tasks. The user behaviour implemen-ted in this work is based on a model, called Lightswitch, which is the result of some studies in buildings throughout the Western World. These beha-viour models mimic how users interact with personal controls (light switches, blinds, window opening). In Figure 1 the typical steps to follow when evaluating the energy performance of a building can be seen. Based on average climate for the place, once defined internal gains, ven-tilation and control strategy, the energy demand of the building can be calculated. From the building energy demand, via the specific plant adopted, the pri-mary energy can be evaluated.

inTRoduCTion导论

此项工作的目的是要评估履约大楼在一个典型年度中的平均能耗。首先，我们创建了一个以DI-GITHON模拟软件为基础的模型。这个模型已经在CEN TC89 WG 5框架下进行了测试，这一模型也用于指导并模拟大楼的热负荷和温度。在我们对一座配有通风与空调系统的大厦进行模拟时，我们可能需要首先估计一下大楼用户的行为方式。通常，人们的实际行为方式各有不同，因此模拟得到的结果与实际能耗情况相比，可能并不准确。而且能耗的测量也不一定准确，因此，很难将测量结果与模拟结果相对比。不过，模拟可以很好地反映出大楼中存在的问题，可作为大楼能效评估的一个参考。在进行办公大楼评估时，一个特殊问题是楼内的人数。办公室内的人员数量并不固

定。也很难预测大楼用户的行为方式，以及人员与设备相互关系。本文中采用了一个名为“Lightswitch”的模型来预测人员的行为，这个模型是西方世界建筑研究中的成果。行为模型可模拟用户操作控制开关（照明开关、窗帘、窗户等）的行为。图1给出了建筑能效评估的一般步骤。根据建筑所在地平均气候条件，一旦确定了楼内热源情况、通风及其控制策略等，就可以计算出该建筑的能源需求量。根据建筑能源需求量，以及具体安装的机电设备情况，就可以对一次能源的效率进行评估。

For simulations the program DIGITHON has been used. It is a program which solves the energy balance in multi-room buildings. The software calcu-lates the sensible and latent load hour by hour by using TRY climatic data. The calculation takes into account temperature and direct and diffuse solar ra-diation, as well as internal loads due to people, equipment and lighting. The effect of inertia of walls and roofs is calculated by using the well known transfer function method.When simulating a building the question is always to find the most appropriate compromise between degree of detail, for taking correctly into account geometry, structures, scheduling of internal gains, ventilation and

ThE ModEl oF ThE Building 大楼模型

我们使用了DIGITHON这个程序进行模拟，它可以解决拥有很多房间的大楼的能源平衡问题。这个软件通过使用TRY 气候数据来计算每小时内的明显的和潜在的负荷。同时在计算当中也考虑了温度、直接和散射的太阳光照以及大楼内的使用者、设备和灯的内部负荷因素。墙和屋顶的惯性影响因素是通过一个应用很广的转换方程计算而来。当我们模拟一个大楼时一直存在的问题是，如何在详细程度（包括大楼的几何形状、结构、内部负荷、通风和系统控制等）与数据输入、计算和输出管理所需花费的时间之间找到一个折中点。常用的方式就

control strategy of the system, and time demand for input, calculations and output manage-ment. It is usually very common to divide the space in zones with different orientation, for taking into account the different impact during the day of solar radiation on external opaque walls, on direct load through windows.The whole building has been divided in eight zones (Figure 2), for considering the effect of solar radiation on the different orientations. Light shelves have been taken into account with a suitable model for considering in a proper way the overall effect of solar factor of these special devices.

是从不同的角度把室内空间划分成很多不同的区域，并考虑在白天外部实体墙和窗户的直接阳光反射的不同影响。根据不同角度的日光照射情况，整个大楼被划分为8个区域（图例2）。利用适当的模型正确考虑了遮阳板光照效果。


为比较能耗情况从而确定节能的可能性，我们针对维护结构、空调系统和设备管理情况设计了5种不同的场景：

• 场景1：参照模式，用中国常用技术建造的大楼，空调机组没有采用热回收技术，安装了风冷冷水压缩机组；冬天大楼内空调末端工作温度是60°C，夏天工作温度是7°C；没有使用楼宇控制系统。

• 场景2：实际建筑，空调机组采用了热回收技术，安装了风冷冷水压缩机组；冬天大楼里空调末端工作温度是60°C，夏天工作温度是7°C；没有使用楼宇控制系统。

• 场景3：实际建筑，空调机组采用了热回收技术，安装了风冷冷水压缩机组；冬天大楼里空调末端工作温度是 60°C，在夏天工作温度是在7°C；使用了楼宇控制系统。

• 场景4：实际建筑，空调机组采用了热回收技术，安装了变风量系统，安装了水冷式压缩机组；冬天大楼里空调末端工作温度是30-35°C，夏天工作温度

是在16°C；使用楼宇控制系统。

• 场景5：实际建筑，空调机组采用了热回收技术，安装了变风量系统，安装了水冷式压缩机组；冬天大楼里空调末端工作温度是30-35°C，夏天工作温度是在16°C；使用了楼宇控制系统；采用了基于阳光辐射的可再生能源（太阳能热水系统和光伏发电系统）。

In order to compare the energies and determining the possibilities in energy saving, five different combinations of envelope, HVAC system and building management have been considered:

• Scenario 1: reference case, i.e. a building with usual construc-tion techniques used in China, without heat recovery on the AHU, equipped with air to water cooled compression chillers; terminal units inside the building run at 60°C in winter time and 7°C in sum-mer time; no BMS installed.

• Scenario 2: actual building with heat recovery on the AHU, equipped with air to water cooled compression chillers; terminal units inside the building run at 60°C in winter time and 7°C in summer time; no BMS installed.

• Scenario 3: actual building with heat recovery on the AHU, equipped with air to water cooled compression chillers; terminal units inside the building run at 60°C in winter time and 7°C in summer time; BMS installed.

• Scenario 4: actual building with heat recovery on the AHU, VAV, equipped with water to water cooled compression chillers; terminal units inside the building run at 30°C-35°C in winter time and 16°C in summer time; BMS installed.

• Scenario 5: actual building with heat recovery on the AHU, VAV, equipped with water to water cooled compression chillers; terminal units inside the building run at 30°C-35°C in winter time and 16°C in summer time; BMS installed; renewable energy due to solar radiation (solar collectors for hot water and photovoltaic systems for electricity).

MAnAgEMEnT项目和施工管理

In order to make possible thiscooperation project of the sinoitalian environmental program, a double project management team has been appointed by the Client: The Italian Project Management Team-Favero & Milan Ingegneria S.p.A., Venice and mOa. The Chinese Project Manage-ment Team-CSCEC Beijing.
