Building activity is one of the most important human activities,and plays a determining role in the formation of the social environment.But simultaneously,itis also a significant consumer ofnaturalresources and an emitter of greenhouse gas (GHG) as well as otherwastes, resulting in irreversible impacts on the natural environment. Statistically, the building sector contributes approximately50% of final energy consumption in the world and 42% of globalGHG emissions during its total life cycle (Guggemos and Horvath,2005).In the 1980s, the agenda for green and sustainable development gathered momentum. Under the influence of this movement,the building sector began to attach importance to energy conservation and emission mitigation during its life-cycle, especially inexploration, transportation and processing of building materials,construction, operation, maintenance, renovation, and demolition.In 1992, the concept of “green building” was formally proposedat the United Nations Conference on Environment and Development (UNCED) in Rio de Janeiro, indicating that buildings shouldmeet occupants’ needs of comfortable living environment withoutcompromising the ability to save energ
