초록
This paper reviewed the validity of IRT from the comparison·analysis of U-value and HFM results ofapartments in Korea, which have been calculated using IRT, and presents the evaluation solution for thermal insulationperformance that can consider the main environmental factors. Side walls of 3 apartments that were constructed in 10-year intervals from one another, were selected as subjects of measurement. The subjects’ environmental impact ofsurroundings and measurement device’s errors were considered for analysis. In result, it is evaluated that there is validityof ±20% error between IRT and HFM measurement methods when reflected temperature is at ±1.0oC range of airtemperature and emissivity is at ±0.2 range.
