As of 2019, the amount of energy used in apartments accounts for the largest portion of residential buildings, accounting for 59 percent. Due to the desperate need for energy saving efforts in apartments, this study used a steady state three-dimensional heat transfer analysis program to compare the temperature distribution and the amount of heat loss depending on the insulation conditions of apartments. The effect of temperature improvement in the proposal plan of creating a thermal buffer space in the corridor compared to the original plan, which is an apartment with internal insulation but does not have continuous insulation between generations and corridors, was shown to be significant. In terms of heat loss, it was also shown that the proposal plan was significantly reduced.
