Research Progress in Life Cycle Energy Consumption Data of Building Subassembly and Equipment

The life cycle building were generally divided into production of building subassembly,construction,operation,maintenance,disposition.In this paper,life cycle resources and energy consumption of building materials(cement,steel,plate glasses,building ceramic,concrete,wall materials) and building equipment(Room Air Conditioner,cold water units,fan coil,pump) in domestic building subassembly were summarized.Besides,The establishment of LCA database and life cycle energy consumption model were introduced.The source of domestic inventory data were also illustrated.
