Abstract

Building manufacturing creates product value like building space, and induces severe environmental influence at the same time. The idea of eco-efficiency (EE) can link a product or service value and the corresponding environmental influence together, but there has been little research that implements such idea on building manufacturing, such as the green building rating system of the comprehensive assessment system for building environmental efficiency (CASBEE) in Japan and the EcoEffect in Sweden. This paper proposes an emergy (spelled with an "m") analysis-based methodology for EE evaluation of building manufacturing, where the building space (in cubic size) and the emergy amount of building manufacturing are selected as the indicators of product value and the environmental influence, respectively. Six residential buildings that include multi-storeys, moderate high-rises and high rises are selected averagely from two Chinese famous cities, namely Beijing and Shanghai. The evaluation results can provide directions to assess environmental influence and thus to heighten the EE of building manufacturing. The EE evaluation result can even be used as the base of a new green building (or eco-building) rating system.
