    Abstract

    In aims to meet the goal of 25% CO2 emission reduction compared to 1990 by 2020, the government has been developing policies on insulation renovations. In order to achieve the previously stated target, all existing houses are required to conduct insulation renovation. Thus, investigations on insulation efficiencies of existing apartments are necessary to verify the effect of insulation renovation on CO2 emissions. The Energy-Saving Standard, which sets the insulation efficiency of housings, was first presented in 1980, followed by the New Energy-Saving Standard in 1992 and the Next-Generation Energy-Saving Standard in 1999. Therefore, insulation efficiencies of housings are considered to be diverse depending on the age of completion. Research on the actual situation of insulation efficiencies in detached houses exists, but those on existing apartments are insufficient. In this study, we investigate the actual situation of insulation efficiencies of existing apartments and conduct an analysis on energy savings and reduction in utility costs through insulation renovation of existing apartments with different insulation efficiencies.
