The paper mainly introduces the design thread and relative techniques of function optimization,storey adding and strengthening,energy and material saving,building intelligence and environmental protection etc.

The key measures for green construction technology are energy saving,material saving,water saving and land saving during construction,as well as protecting environment and guaranteeing professional health.

The article explicates realizing scientific development view from the as- pects of land-saving, energy-saving, water-saving, material-saving and environment protection and promotes the significance of energy-saving land-saving house construction.

High-performance rebars and mechanical splicing technique is an important part of construction energy conservation and material-saving,and also one of the new technologies that popularized by Ministry of Construction.

Based on the existing engineering projects in three different-climate regions in China,the point-supported curtain wall system with no-hole hollow glasses has been researched in such aspects as structure design,mechanics characteristics,energy-saving principle and material-saving features.

The tests show that the diesel has reached the objectives of economized material,energy consumption,low pollution and high reliability,which can meet the requirements of the consumers.

The system is of practicability and is at front of technology,the produce of Saving metal material and energy,and optimization design are realizated,the costs of products is decreased,the level of science-technology and strength of industr.

Analysis of energy saving & material saving and design application of point supported curtain wall with no holed hollow glass;
