Abstract

The deteriorations of earth environment have been of keen concern recently. In constructing the infrastructure construction, a system which would make possible of sustainable use of energy, natural resources and environment is strongly demanded. This study seeks for a new design method which would take into account not only economy and reliability of the structures but also energy consumption and environmental loads. To realize such design method, the energy consumption and the environmental effects are measured by the amount of CO2 emission during the construction. Thus the design become a multiobjective decision making problem which should take into account economy, reliability and CO2 emission simultaneously. Both Analytic hierarchy process and multi-attribute utility analysis are examined as tools to accomplish this task.
