1. Sustainability: multi-faceted

2. Converting all facets to one ‘currency’

3. People believe what they want to believe
And search out arguments and data to support this belief.

4. Most things don’t grow on trees

5. CO2 is key raw ingredient in the primary production

6. Sir Alec Reed Academy, Ramboll engineers
“The development used approximately 1075m3 of timber, which equates to an embodied C02 of 217 tonnes. This is quarter of the embodied C02 within the structure when compared to the next feasible traditional construction method. Taking account the sequestered carbon within the timber the structures will actually have a negative embodied carbon of 640 tonnes of C02.”

7. Longevity: 60 years, 100 years, 900 years?

8. Longevity: Essex timber frame

9. Just need to get the detailing right

10. TRADA published design guidance

11. Waste hierarchy and re-cycling

12. All of a log is used – for different markets

13. Computer control for maximum yield

14. Wood recycling rates: end of life 2012 Wood Recylers’ Association Stats
54% Recycled or energy
29% Landfill
5% Exported – mainly for energy
12% Burned on site or land recovery
Driven by markets and waste taxes and improving all the time

15. Raw ingredient is CO2 100% recycling rate ultimately
CO2 equiv. to Iron ore
Sawn timber equiv. to Rolled steel

16. Energy consumption during processing

17. Energy use of building Many passivhauses are in timber frame

18. Thermal mass

19. When does high thermal mass help you?

20. The solution?

21. Place-making

22. The reality A £300k house needs 2 incomes and generally 2 cars.
It would be nice to have some friends or relatives round – and for them to be able to park!

23. Timber LCA Data

24. Timber LCA data: Cross laminated timber
