An Emergy Methodology of Operational Resources Analysis for Green Construction

The environmental impact of construction process is closely related to the operational resource arrangement of the construction scheme. At the viewpoint of green construction, this research focuses on the onsite construction phase from the preparation to the completion and acceptance. From the perspective of ecological economics, based on emergy theory and its methodology, a comprehensive analysis on the flows of the input-output capital, energy and material is done to the construction operational resources, i.e., manpower, material, and equipment. A framework of emergy analysis is setup connecting ecological and economical system of construction process. This research has theoretical and practical reference for the innovation of rethinking construction operational resources with the sense of green construction.
