5. Learning Outcomes Upon successful completion of the Assessment Test Participants will be able to demonstrate a general understanding of the following Stated Learning Outcomes: • The Low Carbon Economy • The Carbon Cycle & Net CO2 • Sustainability Benefits of Timber Building Materials • Sustainable Forestry Management

6. Goals of green design • Use materials that are • Safe • Efficient • Easy to use • Minimise use of carbon energy • Maximise storage of carbon • LOW CARBON ECONOMY • Overall, the building and its materials are • good for the environment

7. How do we know what’s good for the environment & what’s not? Myriads of claims being made about the green credentials of any given product/organisation/event etc “green washing”

8. How do we know what’s good for the environment & what’s not? THE FACTS Data sourced from Forest and Wood Products Research and Development Corporation Forest and Wood Products Association

9. TIMBER & the LOW CARBON ECONOMY Carbon Cycle CO2 CO2 CO2 Any change that shifts carbon from another reservoir into the atmosphere results in warmer temperatures. emission storage storage Carbon flows between natural storage reservoirs in an exchange called the Carbon Cycle Atmosphere Rocks, Soil, Ocean, Plants, Trees, Fossil Fuel are Reservoirs which store carbon reducing the amount of carbon transfer to the Atmosphere. Rock Soil Rocks, Soil, Ocean, Plants, Trees, Fossil Fuels and Atmosphere are Reservoirs Fossil Fuel Plants Trees Coal Ocean Gas Oil Source: http://earthobservatory.nasa.gov/Features/CarbonCycle/carbon_cycle4.phpv

10. Carbon Cycle Fossil Fuel Energy Multi-Million Year Cycle Renewable Energy 40-50 Year Cycle Coal Gas Oil Source: http://earthobservatory.nasa.gov/Features/CarbonCycle/carbon_cycle4.phpv

11. Some forestry statistics • Fossil fuels take many millions of years to recycle • Renewable energy is much shorter • Timber recycles in only 40 to 50 years. • Storing carbon in sustainably harvested timber ie furniture or building materials for 40 years or longer keeps or improves the “storage” to “atmosphere carbon” ratio.

12. Some forestry statistics • It is estimated Australian forests store around 10.5 billion tonnes of carbon or 38.5 billion tonnes CO2 • Australian Greenhouse Office estimates that in 2005, Australia’s total CO2 equivalent emissions were 559 million tonnes

13. What is Timber? • 50% of timber is carbon • 1 tonne of carbon equates to 3.67 tonnes of CO2

14. Some forestry statistics • In other words, Australian forests are storing around 69 years worth of 2005 level annual emissions. • To lock up Native Forests is a shocking waste of an important resource. • We need to optimise the forest as a carbon sink.

15. Some forestry statistics • Carbon sequestration slows significantly when a tree reaches maturity at around 40 years.

16. Total Carbon Sequestered from Locked Up Forests slows significantly after they reach 40 years old Sustainably Harvested

17. Some forestry statistics • Harvesting forests for non sustainable purposes ie purely for good forest management is counter productive.

18. Total Carbon Sequestered from Non-Sustainable Forestry Unsustainably Harvested

19. Some forestry statistics • Harvesting or thinning new growth mature trees from forests for sustainable purposes significantly increases stored carbon. • Harvesting must be to standards such as: • FSC - Forest Stewardship Council (www.fscaustralia.org); or • PEFC - Programme for the Endorsement of Forest Certification (www.pefc.org); & • no cutting in • High heritage, habitat or old growth forests • Riparian zones • No clear felling

20. Total Carbon Sequestered from Optimised Sustainable Forestry Optimised Sustainably Harvested

21. Harvesting Comparison Sustainable / Non-Sustainable / Optimised Sustainable Harvested Forestry Optimised Sustainably Harvested Sustainably Harvested Unsustainably Harvested

22. Some forestry statistics • Harvesting or thinning new growth mature trees clears space that allows immature trees to flourish. • Replanting not required as natural re-growth replaces harvested trees and maintains existing/natural bio diversity.

23. Net CO2 in Timber Products Timber has significantly lower Net CO2 than other building materials

24. Timber and Sustainability • Timber is the only building material that is completely sustainable • Carbon dioxide sequestered from the atmosphere as trees grow, is the source of carbon in new timber cells. • When timber is used to produce building products, the carbon stored in the timber cells remains locked up for the life of the product.

25. Net CO2 in Timber Products Timber has lower Net CO2 than other building materials for floors, floor coverings, wall frames, roof frames, and windows Average Australian home built mostly from wood products saves 25 tonnes of CO2 in production process

26. Carbon in Timber Products • Timber stores more carbon than ANY other building materials • Sub Floors (joists) • Flooring • Framing • Cladding (Weathertex) • Trusses • Windows and doors • Furniture

27. Carbon in Timber Products • The Green Building Council green star program primarily targets the carbon emissions in the operation of a building. • 1 or 2 points only are available due to selection of PEFC or FSC sourced timber.

28. Carbon in Timber Products • This is starting to change as carbon storage in timber is understood. • Introduction of programs that recognise the carbon stored in timber building materials, such as the green tag program, is starting to gain momentum

29. Carbon in Timber Products The next slide demonstrates that by changing from Brick Veneer, steel frame and steel floor construction to Timber wall, Timber Frame and Timber Floor Construction you reduce the carbon footprint of the building by 51%

30. Embodied Greenhouse Gas Emissions by Construction System BV-Brick veneer, SF-Steel Frame, SF-Steel Floor, -----SI-Concrete slab -------TW-Timber Wall, TF-Timber Frame, TF-Timber Floor Using Timber Building Products – Up to 51% less embodied Greenhouse Gas Emissions

31. Carbon in Timber Products • Whole of life carbon produced in the manufacture of building materials (green tag) is Just as important as the operational carbon footprint (green star) of buildings in temperate climates such as Sydney and Brisbane and lesser extent Melbourne • Green tag is far more relevant in Australia than green star that is important in very cold climates ie Europe

32. Life Cycle Drivers Timber Wall & Floor House 5 star - reducing operation cost of the building Europe: 60 – 70% of costs to do with operation (heating) Australia: Temperate Climate Operation of the building not as important Greentag carbon in the building materials Building Materials significant % of whole of life carbon footprint of any building
