Life-cycle assessment is a process or technique to evaluate the environmental impacts associated with a product over its entire life-span. In the case of a building, life-cycle assessment evaluates the impact of all building materials used in a building through all the stages of its life which include extraction of material, manufacture, transportation, use, and final disposal or end of life. Life–cycle assessment can be used to evaluate the overall environmental impact of the whole building or to quantify the impact of a single material in the building. LEED 2009 awarded points for building material reuse; however, LEED v4 awards points for whole building life-cycle assessment under the “Building Life-Cycle Impact Reduction” credit in the Material and Resources category. There are two variants under life-cycle assessment: Cradle-to-grave (open loop assessment): The cradle-to-grave life-cycle assessment approach includes assessment from the resource extraction phase to disposal phase Cradle-to-cradle (closed loop assessment): The […]
