Abstract

Three-dimensional (3D)printing has been employed in various fields owing to its nonlinear structure and high-accuracy structure implementation capability. Various attempts have been made to improve construction methods and commercialization using 3D printing techniques. In nonlinear structures formed, the construction of the insulation is inevitably limited, and can lead to a degradation of the building energy performance. Therefore, it was aimed to solve the degradation of building energy caused by a limitation in the choice of insulation by using phase-change material (PCM)and a loess. Based on the physical properties obtained experimentally, the building energy to which the hybrid heat-storage system was evaluated using EnergyPlus. The evaluation results show that the increase of energy consumption, which was caused by the decrease of U-Value owing to the restriction of the thermal insulation material can be complemented by employing a hybrid heat-storage system. In addition, the energy consumption can be further reduced.
