In this study, we analyzed reductions in heating costs in remodeled apartments in terms of maintenance fees due to the difficulty in quantitatively assessing the effects of remodeling in aging apartment buildings. A comparison of the heating energy consumption of a subject apartment before and after remodeling showed a reduction of approximately 66.8% per unit area. After accounting for an increase in the floor area due to expansion, the reduction per household was approximately 57.8%. An analysis of the proportion of heating costs within total management fees revealed a decrease of approximately 57.5% after the remodeling. A simulation review using the Zero Energy Building (ZEB) certification system revealed that the remodeled building’s primary energy consumption was 119.0 kWh/m², which achieved ZEB Grade 5 with an energy self-sufficiency rate of 20.94%. These findings confirm that remodeled apartment buildings provide a favorable environment for achieving energy self-sufficiency through rooftop photovoltaic installation. |
