Lighting use characteristics and potential of led replacement of single householdin university town

This study analyzes and quantifies the pattern of single-person households' using lighting fixtures in college neighborhoods. In addition, potential of LED light replacement is estimated based on numerical calculation for applicable decision-making process is presented. This study collected data on occupancy schedule of single-person households in college neighborhoods at 10 minute resolution, their lighting system specification, and utilization schedule in a bid to estimate lighting energy consumption trends in consideration of the characteristics of single-person household. It was found that all subjects studied used only fluorescent lights and incandescent lamps as light sources. If the advantages of replacement LED lights are to be predicted in consideration of such lighting use pattern of single-person households in college neighborhoods, Lighting source replacement only in studio room used as bedroom is expected to result in energy efficiency gain by reducing energy consumption by 45.2kw/year and CO2 emission by 21.3kgCo2/year
