Embodied energy is the energy consumed by all of the processes associated with the production of a building, from the mining and processing of natural resources to manufacturing, transport and product delivery. The single most important factor in reducing the impact of embodied energy is to design long life, durable and adaptable buildings. By assessing the embodied energy of a material, component or whole building, we are able to design buildings which consume less energy in their construction but also during their life cycle. We are conscious in our design approach to use materials that have lower embodied energy as well as consider the most effective construction methods to reduce our impact. Examination of a recent project using eToolLCD, a life cycle assessment (LCA)software, revealed that the estimated embodied energy of the materials used in the building was at 295 GJ. It demonstrates that smart material choices paired with responsible construction methods delivers a sizable reduction in the effect of the building compared to the 1000GJ of energy embodied in the average Australian Home (CSIRO).
