The aim of this study is determining the life cycle assessment of IBS and compares the environmental impacts of building. There are two different kinds of structure has been assessed in this project namely: Timber prefabricate and concrete pre-cast. IBS is a prefabricated structure which component manufacturing in the factory and then transfer to site work for erect. Timbers prefabricate and concrete pre-cast is compared from the initial stage of extracting material to end of life. The method of LCIA in the project is Impact 2002. This project reveals that the total environmental impact of Timber prefabricated is lower than concrete pre-cast in both manufacturing and use phase 100 year life cycle of IBS. Secondly global warming and ozone layer depletion emissions from timber are also much lower than concrete.
