From the tables, we can deduce that in this bibliographic study, 1/3 of the materials are used for thermal insulation and the remaining 2/3 for building materials (the mixture of insulation materials and building materials).
Generally, materials used as building materials have good mechanical performance.
The materials are either insulation materials or building materials with the addition of insulation materials to improve thermal performance (refer with: Table 7).

Summarize the selection of green building materials, and to judge the development trend of green building materials in China.
first session International Conference materials science 1988 first proposed the concept green building materials.1992 convened by the United Nations Conference Environment and Development.1994 addition of Board "sustainable development", International Organization for Standardization ISO to discuss the development of standards for environmentally friendly products, actively promote development green building materials.
Construction of several green building materials as follows: (1) Cement and concrete: Cement and concrete is the largest amount of building materials, traditional cement use a lot of mineral resources and energy, with the progress of science and technology, has now appeared ecological cement.
