PRELIMINARY FINDINGS FROM AN ANALYSIS OF LIGHTING ENERGY USE OF OFFICE BUILDING IN KOREA

초록

In Korea, energy consumption information for existing building is provided to primary energy consumption by fuel types (electric, gas, and district heating) from energy service utilities. To be more effective building energy management nationally, it should be to manage building energy consumption by end use. For this, it is the best approach to collect direct end-use metering data for all buildings but in practically very difficult because of expense and long time. Moreover, it is not appropriate only the application of the building energy simulation based on model to derive energy consumption by end use due to error with energy consumption of actual building. Therefore LBNL has been developed algorithm to estimate energy end use since 1980, the results are EnergyiQ based on web service. The final goal of this research is to develop algorithm to estimate energy end use with real state of Korea, so by selecting the reference buildings to meet the statistical significance level, it is necessary to collect on-site metered data. In this study, the end-use sub-metering of office building in Seoul is ongoing hourly into cooling, heating, ventilation, domestic hot water, lighting, office equipment, elevator, miscellaneous since 1 March 2015. Weather conditions are not a crucial factor for lighting energy consumption in existing office building. So based on this sub-metering data, first we carried out an analysis of lighting energy use profile to utilize basic data in lighting energy consumption estimation.
