시뮬레이션과 실제사용량 비교/분석을 통한 건물에너지효율등급제도의 개선 방향 연구

The certification of the Building Energy Efficiency Rating System (BEERS) is progressed by the annual heating and cooling energy demand, but it is made only through confirmation on and actual inspection of the application of drawings and specifications to the site, and data collection on the operation of buildings and the heating and cooling energy consumption after certification is not made. Studies on the method to compare the energy consumption of the buildings which is certified for BEERS according to the actual certified results with the actual consumption, and to find the cause of errors occurring in generation, and to narrow the errors. Accordingly, this study analyzed the causes of consumption differences as well as consumption by investigating and comparing the theoretical annual primary energy needs (kWh/㎡) and the actual energy consumption for one year of education and research facilities when BEERS certification is required.
