| Abstract |
This study quantitatively analyzed the changes in heating and cooling energy loads resulting from envelope performance conditions and the
application of a smart glazed facade in single-family houses built before the 1990s, using EnergyPlus simulations. Insulation reinforcement
showed approximately 25.7 percent to 31.3 percent reductions in energy loads, while Low-E windows achieved 6.2 percent to 30.3 percent
and the smart glazed facade demonstrated 17.4 percent to 44.3 percent reductions. The smart glazed facade was evaluated as achieving
excellent performance by simultaneously providing dynamic transmittance control and seasonal optimization of solar heat gain. These results
confirm that the smart glazed facade is an effective remodeling option for improving the energy performance of aging single-family houses. |
