Abstract: With the rapid development of economy, the shortage of energy resources has become a serious problem in China. To meet the requirements of sustainable development, a number of worldwide researchers have been attracted by energy efficiency. By analyzing the importance of thermal-insulating and energy-saving and the policy requirements in buildings, the conclusion is drawn out that energy-saving walls plays a key role in improving building energy efficiency. The national classification of thermal-insulating and energy-saving walls, their characteristics and some construction technique are discussed. Meanwhile, a new environmental friendly material is introduced, named as glazed-hollow bead which could be used in the new thermal-insulating and energy-saving wall system. Finally, combined with the actual state in China, some suggestions are proposed on the further development of thermal-insulating and energy-saving walls in civil engineering.
