Through modeling and computing, life cycle energy consumption (LCEC) and environmentalemission (LCEE) of twelve building materials in production process are analyzed by means oflife cycle assessment (LCA). The inventory analysis includes energy upstream, transportationand production phases. Inventory analysis of energy upstream phase is carried out usingiterative computation, while direct energy consumption and environmental emission, indirectenergy consumption and environmental emission are considered. The outcomes show thatLCA integrated value (16.73) of steel production is the highest. The straw bales (0.06) is thelowest, which is therefore called environmental friendly material.
