| Abstract |
This paper proposed a multi-objective optimization method for building energy system design using primary energy consumption and initial cost. The designing of building energy systems is a complex task, because life cycle cost and efficiency of building are determined by decisions of engineer during the early stage of design. Therefore, methods such as pareto analysis that can generate various alternatives for decision making are necessary. In this study, the optimization is performed using the NSGAⅡ, and case study was carried out for feasibility of the proposed method. As a result, alternative solutions can be obtained for the optimal building energy system design. |
