Responsibly sourced wood is The Ultimate Renewable™ building material; it is naturally grown and removes carbon from the atmosphere. Wood products then store the carbon that the growing trees have removed from the air.
Wood has been shown to have positive effects on mental health and well-being. The natural patterns and textures of wood can evoke a sense of warmth and comfort, which has the effect of lowering blood pressure and heart rates, reducing stress and anxiety and increasing positive social interactions.As wood is often associated with nature and the outdoors, having wood incorporated into the home can have a calming effect on the mind and body.
Timber has the ability to exchange moisture with the surrounding air, which provides a buffer against short- term changes in humidity and temperature. Wood is a natural insulator.
The production and processing of wood uses much less energy – called embodied energy – than most other building materials, giving wood products a significantly lower carbon footprint. Wood can be used to substitute for materials that require larger amounts of fossil fuels to be produced.
Embodied carbon emissions in the construction sector account for over 23 per cent of total greenhouse gas emissions in Australia. Over and above operational processes like energy and transport, it is increasingly important to consider the embodied carbon emissions in building materials used in the sector.
There are many benefits of using responsibly sourced wood.
Responsibly sourced wood is renewable. Forests will regrow to provide a wide range of other benefits such as further carbon storage, oxygen generation and forest habitat.
Trees and wood products have a unique ability to store carbon. As trees grow, they absorb carbon dioxide. When the trees are sustainably harvested and used to make wood products, the carbon remains stored in the wood for the life of the product. About 50% of the dry weight of wood is carbon.
Research has identified that the increased use of wood has measurable physiological and psychological health benefits. We now know that workers are less stressed and more productive, students learn better, patients heal faster, and people are generally happier and calmer in spaces that contain natural elements like wood.
The production and processing of wood uses much less energy – known as embodied energy – than most other building materials, giving wood products a significantly lower carbon footprint. As a result wood can be used as a low-emission substitute for materials that require larger amounts of fossil fuels to be produced. As a rule of thumb, if you convert one cubic metre of a solid material, such as concrete or brick, for a cubic metre of timber, you will eliminate approximately one tonne (1000kg) of carbon dioxide from being emitted into the atmosphere.
Wood is the only building material that helps tackle climate change. It is important to remove carbon from the atmosphere as well as reduce new carbon emissions going into the atmosphere. Wood achieves both of these.
In this short (2-minute) video you can see the process of carbon sequestration and how wood stores carbon, from a molecular perspective.
Wood is a durable material for both homes and commercial buildings. When properly looked after it can last hundreds of years. Modern wood preservatives enhance natural durability.
The increased demand for responsibly sourced wood products that store carbon can result in an increase in well-managed forests and plantations on marginal or cleared land.
Wood is a natural insulator due to the air pockets within its cellular structure. As an insulator wood is 15 times better than masonry and concrete, 400 times better than steel, and 1,770 times better than aluminium. This helps to reduce the cost of heating and cooling a building.
Trees and wood products have a unique ability to store carbon. As trees grow, they absorb carbon dioxide. When the trees are sustainably harvested and used to make wood products, the carbon remains stored in the wood for the life of the product. About 50% of the dry weight of wood is carbon.
Research by Planet Ark has identified the positive associations that wood induces in people, where an overwhelming 96 per cent of Australians agreed that wood is ‘visually appealing’ and ‘has a natural look and feel’. Eight out of ten people also thought that wood is versatile, recyclable, renewable and long lasting.
Most wooden building are prefabricated off-site, which makes them fast and efficient to build. The 18-storey Brock Commons building in Vancouver was built in 9 ½ weeks. Wooden buildings can be built year-round in most climates.
Comparative studies of the economics of different wall framing systems indicate that, in terms of direct building expenses, timber frames are consistently the most cost-effective solution.
