3. Sustainability Benefits of Timber Building

Materials

4. Sustainable Forestry Management

& the

• Use materials that are– Safe– Efficient– Easy to use– Minimise use of carbon energy– Maximise storage of carbon

Goals of green design

LOW CARBON ECONOMY

• Overall, the building and its materials are good for the environment

& the

Myriads of claims being made about the green credentials of any given

product/organisation/event etc

not?

& the

• Fossil fuels take many millions of years to recycle

• Renewable energy is much shorterTimber 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.

Some forestry statistics

& the

• 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


& the

• 50% of timber is carbon

• 1 tonne of carbon equates to 3.67 tonnes of CO2

What is Timber?

& the

• 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.


& the

• Carbon sequestration slows significantly when a tree reaches maturity at around 40 years.


& the

Total Carbon Sequestered from Locked Up ForestsSustainably Harvested slows significantly after they

reach 40 years old

& the

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


& the

Total Carbon Sequestered from Non-Sustainable ForestryUnsustainably Harvested

& the

• 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

& the

• 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.

Net CO2 in Timber Products

Timber has significantly lower Net CO2 than other building materials

& the

• 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.

Timber and Sustainability

& the

Average Australian home built mostly from wood products saves 25 tonnes of CO2 in production process

Timber has lower Net CO2 than other building materials for floors, floor coverings, wall frames, roof frames, and windows

Net CO2 in Timber Products

& the

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

Carbon in Timber Products

& the

• 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.


& the

• 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


& the

The next slide demonstrates that by changing fromBrick 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%


& the

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

Embodied Greenhouse Gas Emissions by Construction System

& the

• 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


& the

Life Cycle Drivers Timber Wall & Floor House 5 star - reducing operation cost of the building

Building Materials significant % of whole of life carbon footprint of any building

Europe: 60 – 70% of costs to do with operation (heating)

Australia: Temperate ClimateOperation of the building not as important

C. Use of low Net CO2 Building Products;

D. All of the above.

2. The Carbon Cycle Carbon flows between natural storage reservoirs in an exchange called the Carbon Cycle. Any change that shifts carbon into the atmosphere results in warmer temperatures. Reservoirs which store (sequester) carbon, reduce the amount of carbon transfer to the atmosphere. Which of the following are natural carbon reservoirs?

A. Rock & Soil;B. Plants & Timber; C. Ocean & Fossil Fuels;D. All of the above.

3. Net CO2: Net CO2 may be defined as:

A. The amount of CO2 released during manufacture of a product;
