Research Purpose
Energy consumption in the residential sector is expected to increase continuously as consumers tend to pursue the convenience, caused by an increase in income.
That means, the trend to the large-sized and fashionable household electric appliances - refrigerators, TV, washers, Kimchi refrigerators - has increased the residential energy consumption.
Furthermore, the change of the life style, such as the participation of women in public affairs, the individualism, the information age, the graying trend, the pursuit of environmental pleasure, and the increase of leisure time, have been changing and diversifying the energy consumption pattern.
The purpose of this study is to analyze how the various factors in life styles affect the residential energy consumption. To achieve the purpose, it is necessary to secure the data through the survey on the energy consumption pattern in the residential sector related to the life style.
Summary
This study establishes the residential energy consumption model in house. This model calculates the energy consumption per household by multiplying the energy capacity and the hours of operation by appliances, which are established in each room according to the life styles.
To grasp the energy consumption pattern and the life style in the residential apartment, this study surveys and analyzes the energy consumption related to life styles.
As a result of the survey, the energy consumption per household and per person is 2.341TOE and 0.639TOE respectively. The energy consumption per household by uses is 0.415TOE in heating water, 1.490TOE in heating space, 0.307 in electricity, and 0.131TOE in cooking. The energy consumption for space heating holds 63.6% - two thirds of total residential energy consumption -, heating water 17.7%, electricity 13.1%, and cooking 5.6%.
This study classifies the energy using behaviors in the residential sector into seven such as lighting, heating, cooling, recreation, information, sanitary, and cooking. According to this classification, lighting uses 0.034TOE, heating 1.523TOE, cooling 0.028TOE, recreation 0029TOE, information 0.014TOE, sanitary 0.439TOE, and cooking 0.275TOE - 1.5%, 65%, 1.2%, 1.2%, 0.6%, 18.7%, and 11.8% respectively.
Because the diversification of the life style affects the residential energy consumption, it is necessary to define the pattern of the life style in order to analyze the effect.
This study defines the pattern of the life style as the information-oriented, the graying trend, the participation of women in public affairs, the pursuit of environmental pleasure, the increase of leisure time, the individualism, and the energy saving behavior and analyzes the effects of each pattern.
This study materializes each pattern as the following images. The information-oriented is how long to use information appliances such as computer, the graying trend is how many aging households increase, and the participation of women in public affairs is how many married women get jobs. Also, the increase of leisure time is to increase holidays, the pursuit of environmental pleasure is to increase the frequency of shower and bath and the using time of vacuum cleaner and washer, the individualism is the trend toward nuclear family, and the energy saving behavior is to save energy maintaining the pleasantness.
As the result of the analysis, the information-oriented, the graying trend, the pursuit of the environmental pleasure and the individualism increase the residential energy consumption while the participation of women in public affairs, the increase of leisure, and the energy saving behavior decrease the residential energy consumption.
Because this analysis is based on the materialized images related to energy consumption by patterns rather than the special basic year, however, this study has the limit that cannot compare the result directly.
As the results of the analysis on the changes of energy consumption by patterns, it is estimated that the information- oriented increases 0.011TOE in the energy consumption and 0.007TC in the greenhouse gas emission per household - 0.5% increase on each -, and the graying trend increases 0.004TOE in the energy consumption and 0.002TC in the greenhouse gas emission per household - 0.2% increase on each.
Besides, the participation of women in public affairs decreases 0.030TOE in the energy consumption and 0.018TC in the greenhouse gas emission per household - 1.3% decrease on each -, and the increase of leisure time decreases 0.014TOE in the energy consumption and 0.021TC in the greenhouse gas emission per household - 0.6% decrease on each.
The pursuit of the environmental pleasure increases 0.035TOE in the energy consumption and 0.021TC in the greenhouse gas emission per household - 1.5% increase on each -, and the individualism increases 0.135TOE in the energy consumption and 0.080TC in the greenhouse gas emission per household - 5.0% increase on each.
At the last, the energy saving behavior decreases 0.117TOE in the energy consumption and 0.069TC in the greenhouse gas emission per household - 5.0% decrease on each.
Research Results & Policy Suggestions
The conclusion of this analysis is inevitable that the energy consumption per household will increase if there is no change in the current life style. However, the increase level depends on how much the saving effort of energy consumers in the residential sector is actualized as a real amount.
This study suggests the following measures to save energy consumption in the residential sector. First is the implementation of the energy saving mark system inducing to save the standby power; second is to install the high efficient energy appliance and equipment; third is to introduce the energy management system in the residential sector through using IT(Information Technology) such as home network or HEMS(Houses Energy Management System).
This study contributes to the extended understanding of the residential energy consumption, which is to provide energy consumption data by uses and life style patterns, and the establishment of survey method on the residential sector.
However, it has also limit because this study is the first try to analyze the energy consumption based on the life style pattern. That is, the model surrounding the residential sector is not applied to this study, the sample size is not large enough as like a megalopolis, the grounds of the assumptions on the life style used in the analysis is not sufficient, and some data is not enough.
In the future, therefore, it is necessary to analyze the effect of energy consumption from the life style reflecting the model surrounding the residential sector, to research the actual conditions such as the ownership, the replacement plan, the preference, and the high-cost investment plan of the high efficient energy appliances and the standby power equipment, and to survey the consciousness related to energy saving in order to make out the energy saving behavior menu in the residential sector.
