While various energy efficiency improvement programs with specific energy saving targets are being proposed by governments, the feasibility of those programs and targets are properly assessed in quantitative manner. This research focuses on the enhanced building shell efficiency, efficiency improvement of lighting appliances to reduce cooling energy demand via 9 scenarios discussed in this article using GCAM-EML. Provided in this process of research are quantification of such policy impacts on energy system through scenario simulation results. The results show that this energy efficiency of large buildings are evaluated to be improved at maximum of 4.1% and 8.5% by 2030 and 2055 compared to the reference case. Although this improvement does not seem be large enough, it should be noted that the cumulative energy savings up to 2030 is estimated to be 2.36MTOE and it is 1.16 times of large commercial building energy consumption of 2010 reported by energy survey conducted on 2011. A further detailed research with a more realistic scenarios would better describe how various energy efficiency improvement programs currently deployed affect the overall building’s energy efficiency in the future, and this information could be better utilized for the detailed design of various ongoing energy efficiency programs.
