IEA Annex 45 Energy Efficient Electric Lighting for Buildings
2004 - 2008
Prof. Liisa Halonen 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, 20-30 % in hospitals, 15 % in factories, 10-15 % in schools and 10 % in residential buildings • More than one-quarter of world’s population uses liquid fuel (kerosene) to provide lighting

HELSINKI UNIVERSITY OF TECHNOLOGY, Lighting Laboratory 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?
HELSINKI UNIVERSITY OF TECHNOLOGY, Lighting Laboratory 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
HELSINKI50% UNIVERSITY by OF 2025 TECHNOLOGY, Lighting Laboratory 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.”
HELSINKI UNIVERSITY OF TECHNOLOGY, Lighting Laboratory 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 President Tarja Halonen handed Prize was awarded to Shuji the 2006 Millennium Prize to Nakamura, the inventor of new LED Shuji Nakamura light sources.
