Abstract
Korean energy consumption levels by industry show the construction sector takes up 22% amongst all industries, following the manufacturing sector at 54%. Accordingly, it is necessary to cut down on the energy consumption of existing buildings in the home and commercial sectors. Korean Eco-friendly related regulations and policies have been improved and developed to cut down the energy consumption of buildings, while being limited in application to newly constructed facilities and those using elemental technology. The study suggests a move to more eco-friendly elements of design in office buildings by analyzing the correlation between the elements of buildings, their systems and energy consumption that occurs during the maintenance stage. The analyzed usage data was limited to office buildings, and eco-friendly designing elements were restricted to building/system elements. Also, the range of data was from January to December in 2011 (1year), and the energy consumption was defined as gas, electric, and sewage from the details of maintenance information. The results of this study are as follow. First, buildings facing the southwest have lower average energy consumption in terms of the location elements. Second, according to the analysis on the correlation of energy consumption, in terms of shape elements, the greater the number of elevators, floors, the area of a standard floor and the total floor area are, the greater the sewage output is.
