| Abstract |
The objective of this study was to evaluate and analyze energy performance using TRNSYS 18 for smart skin and typical windows. The results are as follows : The base model for smart skin types in Seoul area was 24% to 37.6%, and the demonstration model was 14.6% to 25.5%, which reduced energy as compared to the target. Also, the reference model in Gwangju was 26.6% to 41.3%, and the demonstration model was 16.0% to 27.4%, which also reduced energy as compared to the target. The base model in the Seoul area was 108.8% to -35.5% and the demonstration model was 105.5% to -25.2%. In addition, the base model in Gwangju was 106.7% to -40.9% and the demonstration model 103.3% to -27.4%, which increased and reduced energy compared to the target. A smart skin and typical type, base model and demonstration model, and energy requirements in Seoul and Gwangju were reduced as the overall u-value was lower. On the other hand, 0.76 (W/㎡?K) showed higher energy consumption than 1.07 (W/㎡?K). In conclusion, energy savings in work facilities are high when the thermal perfusion rate is 1.07 (W/㎡?K). |
