As the problem of floor impact sound in apartment building continues in recent days, various studies and criteria on floor structures have been implemented to reduce the floor impact sound. The floor impact sound isolation structure in apartment buildings has a direct correlation with the thermal performance, because the layer configuration and material properties of floor structure affect the thermal characteristics. Therefore, this study was conducted to investigate the effect of floor structure on thermal performance of radiant floor heating systems. First, the floor impact sound isolation structures were classified as five types (Floor 1 to 5) considering the standard floor system structure recommended by Ministry of Land, Infrastructure and Transport of Korea. The linear thermal transmittance was derived through 2-dimensional steady state simulation and heating energy consumption in housing unit. In addition, the floor impact sound isolation performance was analysis in 1/3 octave band. The linear thermal transmittance shows 1.24 W/mK to 1.42 W/mK, and the heating energy consumption was 73.47 kWh/m2 to 85.00 kWh/m2 depending on the floor structure. However, the normalized impact sound pressure level and Ln,w shows similar regardless floor structure. The results show that the heating energy consumption increases as the linear thermal transmittance increase. Even though the floor structure satisfies the sound isolation performance, energy consumption can show the difference depending on the floor structure. Therefore, the sound isolation performance and the thermal characteristics must be considered together. A further study needs to investigate in-situ condition based on measurement in real household.
