With the rise of BIM application and green building assessment, studies on assessment of CO2 emissions from buildings using BIM are needed. In accordance with the requirements, this study aims at developing BIM Template database, as a part of development of CO2 assessment technology using BIM. Based on the research of construction materials, this study develops database by applying Procurement Agency Item Code to BIM Template. The results of this research makes it possible to assess CO2 emissions of materials with BIM Template and building data modeling implementation.
