  3. 50 years from now,…

  4. I should be

  5. I should be 87 years old

  6. because

  7. because Most women in my family live in their 90’s

  8. 97

  9. But will I?

  10. But will I? Probably not,…

  11. Because

  12. Because by 2050

  13. Because by 2050 London will

  14. be too hot

  15. this is fatal to many elderly

  16. Why?

  17. Why? • NO global effort to reduce carbon emissions so unabated climate change:2-6ºC temperature rise

  18. Why? • NO global effort to reduce carbon emissions so unabated climate change:2-6ºC temperature rise • UK failed to meet its 80% CO2 reduction by 2050

  19. Why? • NO global effort to reduce carbon emissions so unabated climate change:2-6ºC temperature rise • UK failed to meet its 80% CO2 reduction by 2050 • ≈75% of buildings which exist today will still exist in 2050; of which 26 million dwellings

  20. Why? • NO global effort to reduce carbon emissions so unabated climate change:2-6ºC temperature rise • UK failed to meet its 80% CO2 reduction by 2050 • ≈75% of buildings which exist today will still exist in 2050; of which 26 million dwellings • Lack of incentives means they both contribute to CO2 emissions and are ill-adapted to London’s changing climate

  21. Why? • NO global effort to reduce carbon emissions so unabated climate change:2-6ºC temperature rise • UK failed to meet its 80% CO2 reduction by 2050 • ≈75% of buildings which exist today will still exist in 2050; of which 26 million dwellings • Lack of incentives means they both contribute to CO2 emissions and are ill-adapted to London’s changing climate • Heat-related deaths; 2000 in summer 2003 in UK

  22. How hot?

  23. How hot? (2080) • Summers to be 4.5ºC warmer

  24. How hot? (2080) © The Environmental Design Pocketbook

  25. What else? (2080) Sea level rise: 50-90cm

  26. What else? (2080) Sea level rise: 50-90cm up to 26%decrease in summer rain

  27. What else? (2080) Sea level rise: 50-90cm up to 26%decrease in summer rain Up to 32% increase in winter rain

  28. impact?

  29. impact? 1. Increased seasonal water shortages

  30. impact? 1. Increased seasonal water shortages 2. Increased risk of flooding + localized flash floods

  31. impact? 1. Increased seasonal water shortages 2. Increased risk of flooding + localized flash floods 3. Decreased winter fuel-poverty

  32. impact? 1. Increased seasonal water shortages 2. Increased risk of flooding + localized flash floods 3. Decreased winter fuel-poverty 4. Increased summer ‘cooling-poverty’ and health related issues (particularly the elderly at risk)

  33. avoidable?

  34. avoidable? Yes!

  35. avoidable? But we have to future-proof today.

  36. Sounds simple?

  37. It is!

  38. because Although these conditions are new to London, we can borrow from other climates in the world (Mediterranean, Netherlands)

  39. How? By choosing housing interventions which both mitigate and adapt to climate change

  40. How? 5 key interventions

  41. 1. insulate Going to zero carbon

  42. 1. insulate Insulation & increased airtightness reduce winter heat loss but also summer heat gains. Going to zero carbon

  43. 1. insulate Insulate existing housing stock to high standards Going to zero carbon

  44. 1. insulate Passivhaus/EnerPHit or similar Going to zero carbon

  45. Spot the Passivhaus? © bere: architects

  46. 1. insulate We need to think about external insulation (retains thermal mass, reduces thermal bridging & other risks) Going to zero carbon
