Answer: C

Explanation:

The scope of analysis in Materials and Resources Credit, Building Life-Cycle Impact Reduction, Option 4. Whole-Building Life-Cycle Assessment is a cradle-to-grave assessment. This means that the life cycle assessment (LCA) covers all stages of the building’s life cycle, from the extraction of raw materials (cradle) to the disposal or reuse of the building components at the end of their service life (grave)1. The LCA must include the following life cycle stages: product stage, construction process stage, use stage, and end-of-life stage2. The LCA must also account for the environmental impacts of the building’s structure and enclosure, as well as any other building elements that are permanently attached to and share service systems with the building2.
