초록

This study aims to assess the insulation performance of stone-finished exterior insulation system with truss-shaped insulation frames. The evaluation involves measuring the thermal transmittance of concrete exterior walls in small non-residential buildings where this system is implemented. Through on-site evaluation and analysis using the heat flow meter method and the average method, the thermal transmittance of the exterior wall was determined to be 0.188 W/m2K. Following remodeling, the measured U-value showed a 79.0% reduction compared to pre-remodeling, surpassing the calculated U-value at 65.6%. This indicates an enhanced improvement in the thermal bridging effect with the application of an exterior insulation system with truss-shaped insulation frames. Additionally, the difference between the calculated and measured U-values, a critical verification condition in International Organization for Standardization (2014), was less than 20%, affirming the reliability of the on-site measured thermal transmittance.
