Study on optimal energy system design for apartment house using genetic algorithms

The purpose of this study is to propose an optimal design method for the energy system in apartment house using a genetic algorithm and to examine the possibility for the energy conservation of a designed energy system. The energy demand for cooling and heating in apartment house is determined by using TRNSYS. By a modified genetic algorithm called multi-island genetic algorithm, the optimal running pattern of building equipment systems is decided to minimize the energy consumption. An optimal design method for the energy system of the apartment house was proposed using both genetic algorithm and data of cooling/heating demand load simulated by TRNSY. The results show that this proposed method is significantly capable of determining optimal system design for saving energy in apartment house.
