Abstract
Energy efficiency is high on the political agenda. There are many countries that have set goals to be less energy-intensive, to consume less energy and to decrease their carbon dioxide emissions. In the final energy consumption of Korea, the building sector accounts for 17.8% of a total energy consumption in 2013. The purpose of this study was to computed the energy intensity of residential building and commercial building using national statistics for building energy policy. Energy intensities are composed of the final energy consumption as numerator and activity data as denominator. Activity data in this study were population, GDP, value added of service sector, number of household & house, number of building mass and floor area. These intensity can be used as a time-series trend analysis and energy efficiency criteria. Energy intensity per floor area in residential building was $\small{13.28{\times}10^{-3}toe/m^2(154.4Kwh/m^2)}$ in 2013 and was reduced by 43.2% for 1996. Energy intensity per floor area in commercial building was $\small{11.28{\times}10^{-3}toe/m^2(131.1Kwh/m^2)}$ in 2013 and was reduced by 27% for 1996. The graphs and charts show that the time-series trend of these energy intensity has been consistently low.
