The studies on the environmental database of construction materials or the evaluation systems are not sufficient to provide this support adequately during the design stage. This study aims to establish an environmental information database for construction finish materials organized by building element as part of an effort to develop an environmental effect assessment program for buildings. To this end, a classification system has been developed for building elements that satisfies the demands from construction project stakeholders to acquire environmental information. Furthermore, among the construction materials, an environmental database of the finish materials has been developed for each building element based on reference substances and the impact indexes of six environmental effect categories of the national LCI DB.
