Question

I am trying to work out if Vitex, or pacific teak as it is often called, is a sustainable and responsible timber option. Does it have any certification? I believe it comes from the Solomon Islands. Our supplier is recommending it as a good durable choice for our current project that has commercial decking (exposed) and wall lining (partly exposed), however we must use a timber from a sustainable and responsible forestry source.

Vitex grows in the Solomons, also in PNG, Indonesia, Malaysia and the Philippines. Certification will depend on where it is sourced, and is something you will have to pursue with your supplier. Durability is satisfactory for above-ground locations. CSIRO places vitex in Durability Class 2-3 for in-ground use. Timber above ground generally achieves one durability class higher, which would imply a rating of 1-2.

Question

I am involved in an industry group in WA and we are promoting the benefits of building houses using alternate building materials such as wood, in the mainstream project home market. In the WA market residential home construction largely occurs using double brick wall construction. I am seeking any existing research that compares the carbon footprint on a whole of life basis of typical residential homes comparing wood framed V's steel framed V's double brick. Are you aware of any such research ?

The FWPA report Dynamics of Carbon Stocks in Timber in Australian Residential Housing will be relevant to your project and can be downloaded via this link https://www.fwpa.com.au/images/marketaccess/PNA016-0708_Dynamics_carbon_stocks.pdf. An earlier report submitted as a thesis at the University of Adelaide may also be of interest, focussing on the embodied energy of various building materials. It can be downloaded via this link http://file:///C:/Users/peter/AppData/Local/Temp/Pullen1995_MBuildSc-1.pdf.

I'm doing a research on environmentally sustainable timber materials for our recent residence projects. Would you be able to suggest on the possible low embodied carbon timber types and provide some information on the sources?
