Development of a statistical analysis model to benchmark the energy use intensity of subway stations

A statistical model was developed in this study using the benchmark process for 157 actual subway stations in Seoul, South Korea. It includes measured data, utility bills, simulation results, and regression modeling. This adjusted EUI benchmark model was developed using characteristics of subway stations and a statistical validation process. The effectiveness of the model is tested and verified by comparing between measured EUI and adjusted normalized EUI (EUInorm) of actual subway stations. This paper includes the test results of EUI indicator model to benchmark energy performance and assesses existing subway station.
