Evaluation on the energy performance of PAS wall applying vacuum insulation
This study evaluates the insulation performance of the PAS so as to analyze the exterior insulation system, PAS(Panel Approach System), which is fixed to the structure by conducting a mock-up test and then calculates the linear thermal transmittance of the interior insulation and PASapplied areas through a 3-dimensional steady state heat transfer analysis so as to conduct a comparison analysis of heat performance on the interior insulation system in thermal bridge areas.According to the results of the mock-up test conducted to evaluate the insulation performance of the PAS, the thermal transmittance value measured 0.15W/ m2K which shows outstanding insulation performance when compared to the Korean outer wall standard of apartment buildings that is 0.27~0.36W/m2K.Moreover, as a result of calculating the linear thermal transmittance of the PAS in contrast to the interior insulation system through a heat transfer analysis of thermal bridge areas, the interior insulation measured 0.851W/mK, and 0.029W/mK when the PAS was applied.Thus, the insulation performance in thermal bridge areas was reduced by 96.6% in contrast to the interior insulation when the PAS was applied.
