旣存住宅의 에너지 效率等級表示制度 硏究(I) : 대전지역 21개 기존주택과 표준주택의 에너지 성능비교 Comparison of Energy Budget Level between 21 Existing Houses in Daejon and Reference House = Study on the Energy Rating System for Existing Detached Houses by Energy Efficiency (I)

다국어 초록 (Multilingual Abstract)

The objective of the study is to present a certain method that could be classified the existing detached houses over 5 millions in our country by their energy efficiency. The method, will be called KHEES(Korean Home Energy Evaluation System), will contribute to save energy in residences effectively and will change the passive attitude of home owners' energy saving mind to the active one. The principal contents and the scope of the project are as follows.
- Gathering project-related data including papers, reports and existing home energy rating systems of developed countries has done.
- Field survey of the 21 existing detached houses in Daejon city was done to examine their present energy situation and their energy perfomance.
- For the preparation of energy evaluation index a refrence house was designed by using various statistic data from the national census results.
- After analyzing and calculating the yearly energy consumption rate of reference house and existing houses, the comparison between their rates has done.
The principal results of the study are as follows.
- A reference house of 89㎡ is designed, and its annual energy consumption rate is calculated to use as a comparison tool.
- From the comparison of the energy consumption rate between the reference house use and the existing detached houses the fact that the annual energy consumption of the existing detached houses are more from 11% at minimum to 58% at maximum than the reference house.
- The existing detached houses was classified into three groups according to their construction year such as before 1979, from 1980 to 1987. The comparison result of annual energy consumption rate among three groups shows the rate of preceeding group is less about 10% than the rate of succeeding group.
