최적화 방법론에 의한 건물 에너지효율과 신재생에너지 도입 비율 결정 연구

It is required the implementation of zero energy building that improving the building energy efficiency and introducing the RES. This paper was conducted to find out the optimized ratio between building energy efficiency and application of RES when considering policies such as "Building Energy Efficiency Rating" and "Obligation of Renewable Energy Supply Ratio". For this, the study conducted optimization of initial cost with two institutional constraints using EnergyPlus and GenOpt ® . As a result, optimization has been completed the case which is higher performance of the roof than exterior wall. At this time, the primary energy consumption and the duty ratio of the supply of RES has been optimized respectively 256.6 kWh/㎡·yr and 21.6%.
