Straw board is renewable natural building material with the advantages of green environmental protection, strong applicability. But it hadn't been promoted because of many reasons such as technology and economy. Through the analysis ofthe unique advantages and the recent new cases of straw board buildings in Harbin, and the current obstacles to application. The effective ways and the feasible solutions to promote sustainable straw board buildings are summarized.

With the rapid development of the rural economy and vigorous promotion of energy-saving technologies, it is found through a field investigation that the new rural housing in the northeast of China shows new changes on green, energy-efficiency, health, comfort and beauty. The new rural housing mainly applied the technologies of composite energy-saving wall, double or three layers of glass energy saving windows and the roof benzene board insulation, heated in winter by Kang with the fuel of straw, corn stalks and other bio energy, which brings prominent energy-saving effect and the improved indoor environment significantly. The only or main function of the Kang is no longer the heating facilities in winter, but to play its unique benefits of comfort and health for sleep as a bed. the highlights of cultural traditions and customs in Cold rural area, the changes of the Kang are smaller and more exquisite. In the future, northeast rural housing should integrate the technolgies of residential structures, materials and kang further to promote rural sustainable development of society, economy.

this paper introduces An outline of the HS-EPS module building energy saving system of reinforced concrete core columns, its composition, applications and the technical specifications. A comprehensive analysis of the system on technical features and advantages of the system, such as building energy conservation, seismic, industrialization and standardization is introduced. In recent years this system has been applied in many projects in various parts of China including the the application and promotion in the post-disaster reconstruction projects. The ong-term study, extensive analysis and application of this system have proved its high performance, reliable quality and high application value.
