Transcript of "Andreas Schierenbeck, President, Building Technologies, Siemens Inc."

  1. 1. Solutions for Smart Consumption Andreas Schierenbeck President, Building Technologies © Siemens AG 2010. All rights reserved.
  2. 2. Megatrends The world's toughest questions 1% 5% It’s getting warmer Highest CO 2 concentration in the last 350,000 years We’re living longer Average life expectancy increased from ~35 years to ~65 years within one century There are more people in cities In 2050, 9 billion people will live on our planet; many in cities We’re doing business in more places GDP of Least Developed Countries has tripled within the last 20 years Climate change Demographic change Urbanization Globalization
  3. 3. What we know about cities Megatrends pose urgent challenges to cities Cities cover less than 1% of the earth's surface but are disproportionately responsible for causing climate change Currently, around 50% of the world’s population live in cities. Until 2030, 60% of the world's population growth will occur in cities Cities consume ~ 75% of the world's energy and are responsible for up to 75% of GHG emissions and account for 60% of the world's water use Osaka at night
  4. 4. Different cities have different challenges Developed cities Megacities Planned future cities Moderate transition Dramatic growth Forward looking
  5. 5. What we know about buildings Life cycle costs 80% 20% 50 0-1 Cost Years 1-2 2-5 Operation / renovation Demo- lition Design Build Operation cost 60% Energy cost 40% 40% life cycle cost of a building is consumed in energy Industry 31% Buildings 41% 40% of world wide generated energy and 21% of CO2 Transport 28% (direct emissions from primary energy usage) (indirect emissions through power usage) 22 11 13 8 14 18 14 Forestry 14 Agriculture / wast 18 Transport 14 Industry (direct emissions from primary energy usage) Industry (indirect emissions through power usage) Buildings
  6. 6. Buildings consume the most energy, and generate the most CO 2 emission in developed cities Example: Los Angeles Mix of CO 2 emissions (Total 47 Mt 2005) The distribution of CO 2 emission in other developed cities varies (Population size, industrial activities and weather conditions Industry 7 % Transport 26 % Buildings 67 %
  7. 7. Zero net energy buildings … Holistic approach can also save significant energy <ul><ul><li>Energy consumption (heating, cooling, ventilation, hot water …) </li></ul></ul><ul><ul><li>On-site energy generation (solar, wind, geo-thermal …) </li></ul></ul><ul><ul><li>Storage (building hull, water tanks) </li></ul></ul><ul><ul><li>Efficiency in the building (demand control, lighting, air-quality) </li></ul></ul>Zero net energy buildings are coming: CA 2020-2030 / E U 2018
  8. 8. Energy saving possibilities 1) High energy efficiency (Class A) compared to standard equipment (Reference Class C) EN 15232 – Impact of BACS and TBM on energy performance of buildings Energy savings are possible, in every building – in every business Hospital 26% Hotel 41% Residential 27% Restaurant 41% School 26% Office 52% Shopping 49%
  9. 9.
