Energy Efficient Electric Lighting for Buildings

Transcription

1 IEA International Energy Agency Energy Conservation in Buildings and Community Systems (ECBCS) IEA Annex 45 Energy Efficient Electric Lighting for Buildings Prof. Liisa Halonen

2 Background Lighting electricity production 2016 TWh of which 1066 TWh in IEA member countries (1997) Carbon dioxide emissions were 1775 million tonnes, of which approximately 511 million tonnes in IEA member countries Lighting electricity use ranges from 5 % to 15 % in industrialized countries, up to 86 % in developing countries of the total electricity use Global lighting electricity use is distributed: 28% residential, 48% service, 16% industrial, 8% street and other lighting Percentage of the electricity used for lighting in European buildings is 50 % in offices, % in hospitals, 15 % in factories, % in schools and 10 % in residential buildings More than one-quarter of world s population uses liquid fuel (kerosene) to provide lighting

3 Per-Capita Consumption of Electric Light Global consumption of artificial light 133 Plmh

5 Benefits The first question is: What benefit do we get by decreasing these figures? Limit the rate of increase of electric power consumption Reduce the economic costs resulting from constructing new generating capacity Reduce the emissions of greenhouse gases and other pollutants The second question is: What kind of innovative technology do we have or could develop in order to reduce these figures?

6 Light Emitting Diodes According to one scenario LED s share of lighting market: 20% of all illumination by 2010, 50% of all illumination by 2025 Solid state lighting could reduce global energy use for lighting by 50% by 2025

7 Millennium Technology Prize 2006 World s biggest technology prize awarded to Prof Shuji Nakamura September 8, 2006 in Finland for the development of blue, green and white LEDs and the blue laser diode Prof Nakamura, University of California: I hope that this prize helps to raise awareness of the energy savings of using LEDs in illumination, so that the world can realize substantial energy savings.

8 The Millennium Technology Prize The one million Euro Millennium Prize celebrates innovations that have a favourable impact on quality of life and sustainable development. It has been awarded two times: The 2004 Millennium Technology Prize was awarded to Tim Berners- Lee, the inventor of the World Wide Web. The 2006 Millennium Technology Prize was awarded to Shuji Nakamura, the inventor of new LED light sources. President Tarja Halonen handed the 2006 Millennium Prize to Shuji Nakamura

9 LED Applications Automotive Signage

10 Modular LED Lighting System The use of LEDs in general lighting LED luminaire in which the luminous flux, colour properties and the distribution of luminous intensity is adjustable

11 Networking between Europe and Nepal in lighting education and research, Partners: HUT Lighting Laboratory Co-ordinator Kathmandu University Vilnius University FIN Nepal Lithuania Household LED Lighting Project in Nepal Project implemented by Light up the World Foundation. Since 2000, over 1000 households and schools in remote communities of Nepal were equipped with white-led based lightning systems. Powered by pedal DC generators, solar cells, and wind turbines. Low maintenance costs ($3/household/year). LED superseded kerosene lamps and sap-filled pine sticks.
