Description

Present paper proposes the way of a life cycle optimization for building structures with consideration of a hierarchy by ranks of building construction systems by using genetic algorithms, with respect to ecology and economy for evaluations. It is important not only the design of structures itself but behaviors of the designed and constructed structures to be considered in their life cycle. As a different concept from the conventional design methodology, the life cycle design is becoming an essential idea for sustainability. It is required that environmental impact is clearly taken into consideration like economical efficiency in a life cycle design. That is, a life cycle design pursues the optimal solution to both the environmental impact and the economical efficiency which sometimes conflict each other. However, it is very difficult to present the theoritical design solution which satisfies both of those demands simultaneously. In this paper, the design scheme which can propose the building structures as Pareto optimal solutions with which those requirements are satisfied through usage of multiobjective genetic algorithm is proposed.
