| Abstract |
As demand for energy improvement of existing buildings increases, the importance of building information to evaluate energy performance is increasing. It is necessary to collect and analyze energy performance related data since the operation or occupancy characteristics of existing buildings have a great impact on energy use. To manage the energy performance of existing buildings, the purpose of this paper is to survey and analyze the energy use characteristics of public office buildings in Korea, including operational conditions. Sampling was conducted and survey items were estabilshed based on the domestic and international survey cases. Next, we showed the importance and necessity of systematic investigation through correlation analysis between survey items and single regression analysis on energy consumption. |
