Embodied energy is the energy required directly and indirectly to produce a product at specific points in the life cycle of a product. Depending on stage of life cycle, this may include product maintenance and replacement. Building design and the selection of materials, appliances and equipment can all contribute to the minimisation of embodied energy. These notes, curated by the Environment Advisory Group, offer guidance on considerations for embodied energy in your projects. See also the Institute's Embodied Carbon Curriculum.
