외피 성능 및 공사비를 고려한 기존 공동주택의 에너지 절감 잠재량 분석에 관한 연구

This study was conducted to improve the energy performance of the existing apartment house. From the 1980"s, which is the standard of outer wall performance, energy performance test was performed according to strengthen of outer wall performance. Next, we analyze the annual heating Use and costs saved through insulation and window replacement, which represent current insulation performance. Therefore, it is aimed to calculate the energy saving potential for energy policy. As a result, by 2016, performance deviations according to the performance criteria of apartment houses can be divided into 9 sections. The 84m2 type was primary energy of the middle, south, and Jeju regions were 390.8~166.2 kWh/m2·yr. In addition, the 84m2 type was energy saving potential was estimated to be about 8,523/m2 won for the middle region, about 7,052 won/m2 for the south region and about 6,469 won/m2 for the Jeju region. The average payback period for 84m2 type and 59m2 type was 7.07~13.16 years in the middle area, 8.03~12.09 years in the south area, and 4.59~7.46 years in the Jeju area. The potential cost of energy saving for the Jeju area was the highest.
