| Abstract |
Information on provincial level energy consumption pattern of commercial and public buildings, which account for about 49% of domestic building energy as of 2016, is not available yet. In this study, the analysis of provincial level energy consumption characteristics of overall commercial and public buildings is conducted, including small and medium-sized commercial and public buildings. Provincial level building energy consumption pattern is derived, utilizing 2017 Energy Consumption Survey for Commercial and public buildings conducted by KEEI (Korea Energy Economics Institute), presented in aggregated form by sector, fuel, and energy use type, without regional information, and 2017 population census on building establishments conducted by National Statistics Office, Korea.
This disaggregated information resulting from this analysis is applied to GCAM-Korea (Global Change Assessment Model-Korea) for the better representation of the details of commercial and public buildings energy characteristics. As the result, the data show different energy consumption characteristics at provincial level. It is found that existing GCAMKorea underestimates cooling and heating electricity energy while it overestimates other use types of electricity for commercial and public buildings at all regions. The results of this study shed light on regional energy plan for commercial and public buildings. |
