Research on green building materials evaluation system

In comparison to worldwide extremely fast development of construction industry, measurement and evaluation of green building materials is still very weak. This article studies the essence of green building materials, establishes an evaluation index system from resource and energy consumption, and environmental and ecological influences towards different processes including producing, transportation, end using and after discard of the building materials, uses Analytic Hierarchy Process (AHP) method to determine the weights, and then puts forward some specific suggestions on how to promote the greening of building materials.
