Make an informed choice
Every building project involves many decisions, both big and small, on the materials to be used. This can be complex, as every material has an impact on our natural environment and our society in terms of its production, use and disposal. This needs to be weighed up along with the material’s expected contribution to the energy efficiency and comfort of the house, and its financial cost.
Environmental and social considerations for selecting materials include:
- Embodied energy (the energy consumed by all the processes associated with the production of a material, from the mining and processing of natural resources to manufacturing, transport and product delivery)
- Renewability of the raw material
- Durability, longevity and maintenance requirements
- Toxicity of the manufacturing process and the material itself
- Health impacts (for more information, see our Healthy Homes ebook)
- Waste minimisation during production and installation
