This book is based on the requirements of cultivating high-skilled application-oriented talents in higher vocational education, based on the current national construction engineering specifications and documents, and based on the author's many years of practical engineering experience and teaching practice. It has been revised and supplemented many times based on the first edition of this book. There are 10 chapters in the book, and the main contents include: building water supply and drainage engineering, building fire extinguishing system, heating engineering, gas engineering, ventilation and air conditioning engineering, building power transformation and distribution engineering, building electrical lighting engineering, electrical power engineering, building lightning protection and grounding engineering, and intelligent building system engineering. There are questions and exercises at the end of each chapter for readers to review and consolidate. The book downplays theory in the content arrangement. Each installation project is derived from actual engineering projects, follows actual installation procedures and drawing requirements, and is accompanied by a large number of illustrations. It is intuitive and easy to understand, helping readers master knowledge and cultivate practical operation abilities. It is practical, targeted and popular. This book can be used as a teaching book for engineering cost, construction equipment, construction economics and civil engineering related majors in higher vocational colleges. It can also be used as a learning reference for construction and installation engineering technicians and managers.
