建筑节能是直接关系国家能源战略、环境保护和可持续发展的重要研究课题,墙体节能是建筑节能技术的重要研究内容.外墙保温节能技术主要包括外保温技术、自保温技术和内保温技术等.本文从建筑外墙保温节能技术的重要意义谈起,论述了外墙外保温和外墙自保温的主要特点,分析两种保温技术的不同优点,对国内的研究动态进行系统介绍,并提出建筑外墙保温技术的3点思考.

Energy saving of buildings, which is directly related to national energy strategy, environmental protection, and sustainable development, is an important research topic. Energy-saving of external walls is the important research content of building energy-saving technology. Energy-saving technology on external walls mainly includes external thermal insulation technology of exterior walls, thermal insulation technology of inner walls, and self-insulation technology. The importance of thermal-insulating and energy-saving is analyzed and the main characteristics of two kinds of heat preservation technologies are discussed. Research advances in China are systematically introduced. And the considerations involving the insulation technology of building external walls are put forward.
