In construction engineering, applying modern central air conditioning technology not only can improve the overall performance of the building structure but also can enhance the comfort of building use. At the same time, the organic combination of HVAC technology and architectural design can reduce building energy consumption, achieve the goal of energy saving, implement the scientific concept of development, and promote the sustainable development of the national economy. Modern coal-fired boiler is a large energy consumption equipment, how to do a good job in boiler operation and energy saving, this book explores the possibility of coal-fired boiler energy saving from the aspects of boiler technical transformation, fuel saving control and operator management training, so as to provide reference for the actual production of coal-fired boiler energy-saving operation.
   With the continuous improvement of China’s economic and social development and urbanization development level, the quantity and quality requirements of infrastructure construction in China are constantly improving, in which construction engineering is an important part of infrastructure. Energy saving and emission reduction is of great significance to the implementation of the scientific outlook on development, the construction of a harmonious socialist society, the improvement of people’s quality of life and the realization of sound and rapid economic and social development.

随着我国经济水平的不断提升和农田水利工程的持续进步，农田水利工程建设管理得到了越来越广泛的关注。农田水利工程建设是农业发展的最基础的条件，如何在农田水利施工过程中加强科学化管理，健全农田水利建设体系和完善管理和维护措施，为社会主义现代化农业生产做出更大贡献，是本书重点讨论的问题。本书从阐述农田水利与工程管理相关问题入手，对农田水利与工程管理等方面进行了分析和阐述。

Since the reform and opening up, with the advancement of industrialization and urbanization, the rapid economic and social development has brought dual effects on rural water resources. On the one hand, traditional industrial and agricultural production methods as well as urban and rural lifestyles cause serious pollution to rural water resources. On the other hand, the economic development and the improvement of people's living standards have put forward higher requirements on the quantity and quality of water resources and the safety and quality of agricultural products. In recent years, such conflict has become increasingly prominent, and has become an urgent problem for governments at all levels and a hot spot of social concern. To solve this problem, we are not only dealing with three agricultural problems, but also dealing with the major livelihood issues related to the health and safety of people's drinking water and food, and an important issue related to the construction of a harmonious society.
  According to the statistics from the World Health Organization (WHO), 80% of global diseases are related to direct drinking of unclean drinking water; as of the end of 2004, 1.1 billion people worldwide still lack access to safe drinking water and 2.6 billion lack basic sanitation. From the year of 2000, the European Union has issued multiple comprehensive reports on drinking water quality through sampling and analysis of drinking water sources in its member states, summarizing the improvement of drinking water quality in Europe. The United States Congress passed the Safe Drinking Water Act in 1974 and revised it twice in 1986 and 1996, authorizing the United States Environmental Protection Agency to establish national drinking water standards to ensure human health, and prevent natural and man-made pollution in drinking water. At the same time, the US Environmental Protection Agency, each state, and water supply systems are required to cooperate and work together to ensure that drinking water meets national standards. Our country also attaches great importance to drinking water safety. During the “Tenth Five-Year Plan” period, we have formulated and implemented plans like “Relieve Rural Drinking Water Difficulties” and “Rural Drinking Water Safety Emergency Plan”, which solved the drinking water problem for more than 56 million rural residents and rural drinking water safety problem for more than 11 million residents. This is really a big achievement.

改革开放以来，随着工业化、城镇化的推进，经济和社会的快速发展对农村水资源产生了双重的影响：一方面是传统的工农业生产方式和城乡生活方式，对农村水资源产生严重的污染， 另一方面是经济发展和人民生活水平提高对水资源的数量、质量和农产品安全品质都提出了更高的要求。近几年来，这一矛盾日益突出，并已成为各级政府迫切需要解决的难题和社会关注的热点。破解这一难题，不仅是解决三农问题的需要，而且是关系到人们的饮水、食品等健康和安全的重大民生问题，是关系到和谐社会建设的重要问题。
      据世界卫生组织（WHO）统计，全球 80%的疾病与直接饮用不清洁饮用水有关；截至 2004 年底，全球范围内仍有 11 亿人口得不到安全饮水， 26 亿人缺乏基本的卫生条件。从 2000 年开始，欧盟通过对其各成员国饮用水水源地进行取样分析，发布了多期饮水水质综合报告，综述了欧洲饮水水质改善的水平。美国国会 1974年通过了安全饮用水法，并于 1986 年和 1996 年先后两次进行修订，授权美国环保署建立基于保证人体健康的国家饮用水标准，以防止饮用水中自然和人为的污染，同时要求美国环保署、各州和供水系统互相协作、共同努力，以确保饮用水符合国家标准。 我国对饮水安全也高度重视， “十五” 期间制定并实施了“农村饮水解困” 、“农村饮水安全应急规划”等计划，解决了 5600 多万农村人口的饮水问题及 1100多万人的农村饮水安全问题，取得了较大的成效。

Can we imagine that there is no beauty in human life? For example, the house only needs to keep off the wind and rain, the clothes only need to be warm and durable, and the utensils only need to be practical and durable. Maybe people can endure such a life for a short time under special conditions, but in the long run, the human heart will be exhausted, they will no longer have the motivation to pursue ideals, and human society will collapse. This kind of human life is incredible. Especially in 21st century, almost everywhere in our life is permeated with the factors of beauty and art: street greening, lighting layout, decoration and music of shopping malls and shopping centers, commodity design and packaging, overwhelming advertising, as well as fitness, tourism, plastic surgery are all related to beauty.
  Modern Chinese uses “perfect” and “happy” to refer to the ideal state that people desire, which uniquely shows that beauty is the constituent element of the highest value. From the word “beautiful”, we can deeply appreciate the meanings of such words as “Virtue”, “good name”, “good tale” and “good wish”, and then we can understand the motivation, way and result of human society’s praising behavior. We need not only “good”, which is ethically beneficial to others and society, but also “beauty”. Therefore, from the perspective of today’s civilized society, beauty is not only a kind of sensory enjoyment, but also a kind of spiritual enlightenment and life realm.

我们能够设想人类的生活中没有美一例如房子只要挡风遮雨、衣服只要保暖耐穿、器物只要实用坚固等这样的生活吗？也许，人在特殊的条件下可以短时间忍受这样的生活，但从长久来看，这样的人类生活是不可思议的。因为人类的心灵将因此而枯竭，不再有追求理想的动力，人类社会将由此陷于瘫痪。特别是在 21 世纪的今天，我们的生活中几乎无处不渗透着美、艺术的因素：街道绿化、灯光布置，商场和购物中心的装饰和音乐，商品设计及其包装、铺天盖地的广告，以及健美、旅游、整容，无不与美观、漂亮有关。

现代汉语以“完美”“美满”来指称人所希求的理想状态，颇为独特地说明了美是最高价值的构成要素。我们从“美好”一词去深入体味诸如“美德”“美名”“美谈”“美意”等词语的含义，便会理解人类社会褒扬的行为动机和行为方式以及行为结果，不只是需要“好”一伦理上有益于他人、社会的“善”，而且还需要“美”。因此，从今天文明社会来看，美不仅仅是人的一种感官享受，同时也是一种精神启迪和生活境界。

Construction engineering is a complex and comprehensive project. In the construction process of construction engineering, it should fully rely on the fine construction management, fully implement the concept of green construction management, fully improve the overall effect of construction management and fully promote the comprehensive and rapid development of construction industry. In the construction of construction engineering, actively implementing the green management concept and innovating the green management methods can not only guarantee the construction project high quality construction and construction benefits, but also optimize its ecological and environmental benefits.
  Green construction management can be defined as the construction management technology to minimize adverse impact of construction management activities on the environment, reduce the consumption of resources and energy and achieve sustainable development through effective management system and work system. Green construction application is the application of the thought of sustainable development in engineering construction management. It is the comprehensive application of green construction management technology. Green construction technology is not a new technology fully independent from the traditional construction management technology. It is a re-examination of traditional construction technology from a sustainable perspective; it is a construction management technology that follows the strategy of sustainable development.
  In the practice of construction engineering, the continuous increase of building energy consumption greatly affects the sustainable and rapid development of the construction industry. In order to improve the development quality and ecological environmental benefits of construction industry, we should actively and comprehensively implement the concept of green construction management, adopt scientific and efficient green construction methods and countermeasures and better improve the overall level of green construction management.
