Cost, Energy and Global Warming Potential (GWP) Impact of Future Lighting Systems in EU 27
Joint 11th Socio-Economic Metabolism Conference and 4th ISIE Asia-Pacific Conference, Melbourne, November 17-19
Currently about 20% of global electricity consumption is used for lighting which is not very efficient yet. To response to the energy saving issue, choosing a more efficient lighting system becomes a mandatory way according to some legislations in EU27. Although there were some research studies on the specific lighting technologies, life cycle assessment of different lighting systems, and energy consumption modeling. However, none of them can tell us how much energy consumption and CO2 emission can be reduced due to the lighting system transition as well as the cost benefits in the view of customers. In 2012, 27% of CFL (Compact Fluorescent lamp), 26% of Halogen, 22% of incandescent, 11% of Linear Fluorescent, and 13% of LED lamps are used in Europe. In 2020, the LED is expected to share 77% of the domestic lighting market and the incandescent lamps would be eliminated completely. Based on these kind of information, this study shows the quantitative assessment of the energy consumption, global warming potential and cost of the future lighting system as well as a practical case in the EU 27 level which can be interpreted the developed methodology. In this study, it made by three parts; after the goal and scope of the study being conducted, the first part is the benchmarking of the current lighting system in EU 27, the following part is the development of future scenarios by combing the legislations and technology improvements, and the last part is development of three assessment models which shows the results from the three formulas developed in the assessment models (the energy consumption value, and the global warming potential value of the lighting transition as well as the quantification of cost saving for users).
