Definition

The interdependent relationship over a building’s lifecycle between embodied energy (the energy consumed to extract, manufacture, transport and install materials and components) and operational energy (the energy consumed to heat, cool, ventilate, light and power the building during use), where choices that change one often affect the other and the trade‑off determines total life‑cycle energy use
