Evaluation on the Energy Performance of PAS Wall Applying Vacuum Insulation

Abstract:

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 PAS-applied 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/㎡K which shows outstanding insulation performance when compared to the Korean outer wall standard of apartment buildings that is 0.27~0.36W/㎡K. 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.
