Abstract
Energy is essential resource to modern society and is a key in determining whether or not sustainable development. In the energy consumption of buildings in Korea, the building sector accounts for 18.2% of a total energy consumption. The purpose of this study was to computed the energy efficiency indicator of residential building sector using national statistics as indicator factors for building energy policy. Energy efficiency indicator are composed of an energy consumption as numerator and an activity data from national statistics as denominator. National statistics data in this study were energy consumption statistic, GDP, population, number of household & house, number of residential building mass and floor area. This study proposed that house unit-based indicator (toe/house) and floor area unit-based indicator ($\small{kgoe/m^2}$) were useful as the energy efficiency indicator for residential building sector. These indicators can be used as a time-series trend analysis and energy efficiency criteria. Energy intensity per house unit was 1.4toe/house in 2012 and it showed a high reduction rate of 35.1% during the analysis period. Energy intensity per floor area was $\small{13.7kgoe/m^2}$ in 2012 and was reduced by 55% for 1996. The graphs and charts show that the time-series trend of these energy efficiency indicator has been consistently low.
