As of 2009, South Korea is ranked as the 10th largest country in
final energy consumption (229 Mtoe), the 9th in electricity consumption
(437 TWh), and the 8th in CO2 emissions from energy
combustion (518.1 Mt CO2) [1e4]. Particularly, in the last five years
(2006e2011), electricity consumption in Seoul, the capital of South
Korea, has increased by about 19%. Also, after an incident on
September 15, 2011, which almost caused a blackout, the entire
country reconsidered the importance of predicting electricity
consumption [5]. Meanwhile, as of 2011, 58.2% of the total energy
consumption in Seoul has been from construction industry [6].
Accordingly, Seoul introduced the Total Amount of Energy Consumption,
and established a plan to reduce building energy consumption
in 2030 by 20% compared to 2000
