The harmonious coexistence of people and the built environment is the constant development theme of architecture. At present, China’s housing industry is mainly developing in the direction of prefabricated housing construction technology, and the concept of green building should be integrated into it. On the premise of ensuring that the function of the building itself remains unchanged, the building life and use function should be guaranteed, energy conservation and emission reduction should be achieved to the maximum extent, and the utilization of energy and land shall be planned in the most reasonable way to provide a more comfortable environment based on ensuring people’s survival needs. Therefore, the concept of green building is becoming more and more important and closely related to the living environment. The purpose of this book is to deeply discuss the relevant concepts and application technologies of prefabricated buildings and green buildings, in order to provide opinions and references for the development of China’s housing industry. 

This book is mainly divided into eight chapters to describe the technical knowledge of green buildings and prefabricated buildings, including the explanation of the concept knowledge of green buildings, the design highlights of green buildings in planning and the development of combining previous experience, the design and application analysis of building in energy saving, materials required for prefabricated buildings like concrete, steel bars and steel, discussion and research on the design of prefabricated buildings, key technologies of prefabricated buildings during construction like component installation and connection technologies, analysis and control of the cost of prefabricated buildings. I hope to provide readers with ideas and technical knowledge reference and contribute my own strength.

Green Building technology, as a new application cutting-edge technology for building a harmonious society, achieving sustainable building goals such as health, comfort, energy conservation and environmental protection, is bound to get great development in today and in the future when energy conservation and emission reduction are increasingly valued. However, due to its contents involving architecture, building environment, building environment and equipment engineering, water supply and drainage engineering, building materials and many other professional aspects, different professional background personnel have different understanding and focus on it. In fact,  the major of building environment and equipment engineering, as the leading major in the implementation of building environment technology and green building technology, has its unique advantages in its technical application. This book focuses on the application and evaluation of green building technology from the perspective of technology, using the basic theoretical knowledge of building environment and building thermal engineering. The main features of this book are as follows: (1) closely combining the application of green building technology and evaluation examples, to avoid empty technical introduction and theoretical analysis; (2) combining the contents of “Green Building Evaluation Standard” and “green building evaluation mark” closely, a systematic case study is carried out. The research content is practical and operable; (3) closely combining with building energy conservation, water resource recycling technology and mode, material recycling mode to introduce and analyze the application of technology, so as to avoid the unsystematic and emptiness of the content; (4) In the process of writing, we should not emphasize the advanced and high technology of green building application technology. The combination of mature technology and appropriate technology is conducive to the application and popularization of technology in engineering practice, and has a wider application. This book comprehensively expounds and analyzes the green building technology and cost from seven chapters, hoping to be helpful for the project development of relevant staff.

绿色建筑技术作为构建和谐社会、实现健康、舒适、节能、环保等可持续建筑目标的新型应用前沿技术， 在节能减排日益重视的今天和未来必将得到巨大的发展，然而由于其内容涉及建筑学、建筑环境学、建筑环境与设备工程学、给水排水工程学、建筑材料学等众多专业面，不同专业背景人员对其理解和掌握关注的重点有很大区别。实际上建筑环境与设备工程专业作为建筑环境技术和绿色建筑技术实施的主导专业，在其技术应用层面有其独特的优势。本书编写重点从技术角度出发，利用建筑环境学和建筑热工等基本理论知识，对绿色建筑技术的应用及评价展开详细的编写，本书编写的主要特点体现在以下几个方面： （1）紧密结合绿色建筑技术应用和评价实例展开编写，避免空洞的技术介绍和理论分析；（2）紧密结合《绿色建筑评价标准》和绿色建筑评价标识的内容展开系统的实例应用研究， 研究内容具有实用性和可操作性； （3） 紧密结合建筑节能、水资源再循环利用技术及模式、材料再循环利用模式等展开技术应用介绍和剖析，避免编写内容的不系统性和空泛性； （4）编写时不过分强调绿色建筑应用技术的先进性和高科技性，而着眼于成熟技术的组合和适宜技术的联合应用，有利于技术在工程实际中的应用和推广发展，具有较广的应用面。本书从七章内容对绿色建筑技术与造价进行全面的阐述与分析，希望能够有助于相关工作人员的项目开展。

Construction industry is one of pillar industries in China. For a long time, the extensive management of construction industry has caused a lot of waste of resources and serious environmental pollution. Green construction is one of ways to solve this problem. However, China’s construction industry has a weak awareness of environmental protection, imperfect relevant laws and regulations, imperfect supervision and evaluation system. To change the current situation, it requires efforts of relevant departments and the support of the government, and also requires the construction personnel to consciously implement the concept of green construction. This book will give a brief overview of the relevant content of green construction, green building materials, green building construction content, green building evaluation, etc.

Why do we develop prefabricated buildings in China? Although the existing traditional technology in China has made great contribution to the rapid development of urban and rural construction, its disadvantages are also very prominent: the first is extensive type, with serious waste of steel and cement; the second is excessive water consumption; the third is dirty, disorderly and poor construction site, which is often an important pollution source of urban inhalable particles; the fourth is serious common quality problems, cracking and leakage; the fifth is soaring labor cost, difficult recruitment management and quality control (this is the most essential one). This shows that the traditional technology has to be changed. In addition to the requirements of energy conservation and emission reduction, we must accelerate the transformation and vigorously develop prefabricated buildings.
   This book summarizes the experience of domestic prefabricated building construction and other aspects, which is clear-cut, easy to understand, and convenient for readers to quickly understand the relevant knowledge of prefabricated building. In the process of writing this book, we have referred to a large number of literature, as well as a large number of domestic and foreign enterprises’ achievement experience and classic cases. We are thankful for relevant enterprises in the book for their great help and support. Prefabricated technology is not a one-to-one technology, nor a closed and conservative technology. Only when all enterprises in the whole society work hard and strive for it and break the barriers of experience technology, can this cause of benefiting mankind be developed.
    Due to the limited level of editors, there will inevitably be omissions and deficiencies in the book. Readers are sincerely welcome to criticize and correct them.

我国为什么要发展装配式建筑？我国现有的传统技术虽然对城乡建设快速发展贡献很大，但弊端也十分突出：一是粗放式，钢材、水泥浪费严重；二是用水量过大；三是工地脏、乱、差，往往是城市可吸入颗粒物的重要污染源；四是质量通病严重，开裂渗漏问题突出；五是劳动力成本飙升，招工难管理难、质量控制难（这一条恰恰是最本质的）。这表明传统技术已非改不可，加上节能减排的要求，必须加快转型，大力发展装配式建筑。
  本书总结了国内装配式建筑施工等方面的经验，层次分明，通俗易懂，便于读者快速了解装配式建筑的相关知识。本书的编写过程中，参考了大量的文献资料，也参考了大量的国内外企业的成果经验与经典案例，感谢书中相关企业的大力帮助与鼎力支持。装配式技术并非一家一门的技术，也不是封闭和保守的技术，只有全社会各家各企业共同为之努力和奋斗，打破经验技术的壁垒，才能将这项造福人类的事业发展起来。
  由于编者的水平有限，书中难免会有疏漏， 不足之处，恳请广大读者批评指正。
