Abstract:

This paper presents a simulation technology of environmental impact for the building. By emergy analysis method, emergy costs of building(or construction engineering) can be calculated in the life cycle. It includes the engineering cost, environmental cost and social cost of building. Through integrating GIS technology with multi-agent technology, life cycle substance and energy metabolism of building (construction engineering) can be simulated and their environmental influence can be dynamically displayed. Based on the case study of entries works ‘Sunny Inside’ by Xiamen University in 2013 China International Solar Decathlon Competition, we discovered the changing pattern of surrounding environmental impact from waste streams of the zero-energy building and ordinary construction. The simulation results verified and showed the Odum principles of maximum power. This paper provides a new research perspective and integration approach for the environmental impact assessment in building and construction engineering. The result will help decision-making in design and construction engineering scheme.
