Passivhaus Conference Keynote Presentation – Nov 2007


Published on

Buildings account for about 33% of all CO2 emissions. Add the fact that what we build today will likely be around for another 50 to 100 years and you understand why "incrementalism is death" in our built environment. The technology, materials and talent exists today. All we need is the courage to take the necessary leaps in constructing comfortable, beautiful, achievable, sustainable buildings now.

Passivhaus Conference Keynote Presentation – Nov 2007

  1. 1. Introduction Incrementalism is Death a personal opinion to energy and buildings Stephan Tanner, Intep – Integrated Planning LLC, USA
  2. 2. Energy Matters!
  3. 3. Energy Matters! Transportation Industry Buildings
  4. 4. Global Warming additional information: Rhone Glacier 1990 1601 1856 1940
  5. 5. Global Warming (Petit et al. 1999) Today CO 2 concentration is already higher than ever in the last 400’000 years Atmospherical CO 2 concentration (ppm) Years before today Source: Intergovernmental Panel on Climate Change - 400’000 300’000 200’000 100’000 today 200 240 280 320 360 400 2100: Scenarios up to 1100 ppm 2000: Today, 380 ppm 1800: pre-industrial, 280 ppm
  6. 6. Global Warming Goal: Stabilization at 550ppm = 1 Ton of CO2 - max. 500 Watt of fossil fuel annually per person Source: Watson
  7. 7. Global warming - Economic Impact: <ul><li>&quot;The Biggest Market Failure the World Has Ever Seen” Sir Nicholas Stern, former Chief Economist of the World Bank, February 2007: </li></ul><ul><li>Nicolas Stern Report: </li></ul><ul><li>The cost of reducing emissions could be limited to around 1% of global GDP; people could be charged more </li></ul><ul><li>Unabated climate change could cost the world at least 5% of GDP each year; if more dramatic predictions come to pass, the cost could be more than 20% of GDP. </li></ul>Source: The McKinsey Quarterly 2007 - 1
  8. 8. Global Warming USA: Current annual CO 2 emission per person: 20 Ton of CO 2 Global Warming Goal by 2050: 1 Ton of CO 2
  9. 9. Energy Vision: <ul><li>‘ 2000 Watt Society’ </li></ul><ul><li>1500 Watt renewable energy </li></ul><ul><li>500 Watt fossil energy </li></ul><ul><li>Source: ETH Novatlantis: </li></ul>

  11. 11. Energy demand related to Buildings: 38% to 48% Source: US Energy Information Administration
  12. 12. Building Life-Cycle: 50 to 100 years Source: Intep GmbH
  13. 13. Incrementalism is Death ! We build today for 2050 and beyond.
  14. 14. Building Energy Benchmarks Example State of Minnesota Today 100% MN Energy Code 315 kWh/m2a -60% LEED Platinum 190 kWh/m2a -85% Passivhaus Standard 45 kWh/m2a
  15. 15. We can do it today ! Over 6000 Passivhaus Buildings have been build today
  16. 16. Let’s make the step together! I look forward to have a great dialog about ideas, experiences and challenges at this conference. THANK YOU!
