Resource Allocation & Materials Flashcards

Which Envision credit rewards projects for reducing the amount of material consumed through design optimization?

Answer: RA1.1 – Reduce Net Embodied Energy

RA1.1 encourages minimizing embodied energy—and by extension material use—through right-sizing, material efficiency, and optimization.

What is the key difference between 'pre-consumer recycled content' and 'post-consumer recycled content' in materials?

Answer: Post-consumer content comes from material that was used by end consumers, while pre-consumer is manufacturing waste rerouted before reaching consumers

Post-consumer recycled content has completed its intended use (e.g., recycled bottles), while pre-consumer is manufacturing scrap never reaching end users.

Why is regional material sourcing emphasized in sustainable infrastructure projects?

Answer: It reduces transportation-related emissions and supports local economies

Shorter supply chains lower fuel consumption and transportation emissions while keeping economic benefits within the local community.

A bridge project uses timber certified by the Forest Stewardship Council (FSC). This certification PRIMARILY addresses which sustainability concern?

Answer: Ensuring wood is harvested from responsibly managed forests that protect biodiversity and workers

FSC certification verifies responsible forest management including biodiversity protection, indigenous rights, and sustainable harvest rates.

In life cycle assessment, what does the 'cradle-to-gate' boundary include?

Answer: Raw material extraction through manufacturing, stopping before transportation to the construction site

Cradle-to-gate covers raw material extraction, processing, and manufacturing but excludes transportation to the project site, use, and end-of-life.

Which construction waste management practice aligns BEST with Envision's resource allocation goals?

Answer: Developing a waste management plan with sorting, reuse, and recycling targets before construction begins

Pre-construction waste planning sets diversion targets, identifies reuse opportunities, and establishes sorting protocols to minimize landfill disposal.

Slag cement used as a Portland cement substitute in concrete is MOST valuable because it:

Answer: Is an industrial byproduct that reduces cement clinker demand, lowering embodied carbon

Ground granulated blast-furnace slag (GGBS) is a byproduct of iron manufacturing that replaces clinker—the most carbon-intensive concrete ingredient.
