As the demand for energy efficiency improvement in the residential sector increases, a reference model for the residential sector is needed as a fast and cost-effective means for improving the energy efficiency of existing buildings. Therefore, this study selects the energy performance variable of the reference model for energy consumption prediction of low-rise residential buildings and proposes the range of the variable. The variables were verified by comparing the energy consumption simulation results of the reference model and the national energy consumption statistics, and the results are as follows. (1) The energy variable was proposed as the building use and reference gross area, design variable, passive performance variable, user variable, and active performance variable. (2) The energy variable of the energy requirement is analyzed to have an influence of R2 = 0.819, which defined in this study is analyzed to be valid. (3) The trend of energy consumption and usage by variable range is analyzed as the same trend in the result value. (4) The error of the absolute value is analyzed as satisfying the criterion of CV (RMSE) ¡¾30% of the error indicator. |
