초록

In South Korea, Energy Performance Index (EPI) approach has been used as a building energy standard for new buildings. It quantifies the EPI score using two different weights based on selected design variables according to building usage, gross floor area, and region. However, it has been well acknowledged that this prescriptive approach does not sufficiently account for the nonlinear interwoven relationship among the design variables. With this in mind, the authors collected actual monthly energy data from 102,400 existing non-residential buildings in South Korea and investigated the correlation between the obtained EPI scores and the measured EUIs as well as between the design variables (U-values of the building envelope) and the measured EUIs. It is found that the current EPI rating method does not always explain the energy performance of existing buildings.
