Life Cycle Assessment
Life Cycle Assessment is an emerging methodology that assesses the environmental impact of building materials by measuring the amount of resources required at the development, transport and disposal phases of their lifecycle. In other words, a cradle to grave analysis. Whilst Life Cycle Assessment is the most accurate methodology for assessing the environmental impacts of buildings, it is not currently a viable option for small scale individual buildings.
