Resource Allocation & Materials Flashcards

What does lifecycle assessment (LCA) evaluate in the Envision framework?

Answer: The environmental impacts of a project from raw material extraction through end of life

Lifecycle assessment evaluates all environmental impacts across a project's entire lifecycle: material extraction, manufacturing, construction, operation, maintenance, and end-of-life disposal or recycling.

How does Envision encourage the use of recycled materials in infrastructure projects?

Answer: By awarding credits for using recycled and locally sourced materials that reduce virgin resource consumption

Envision awards sustainability credits for incorporating recycled, reused, and locally sourced materials, reducing the demand for virgin resources and minimizing transportation impacts.

What is 'net-zero energy' as applied to infrastructure in Envision?

Answer: A project that produces as much renewable energy as it consumes over its operational lifetime

Net-zero energy means the project's renewable energy generation equals or exceeds its total energy consumption over its operational period, resulting in no net energy draw from the grid.

Why does Envision emphasize reducing potable water consumption in infrastructure?

Answer: Potable water is a finite resource and reducing its use conserves supply for drinking and essential needs

Envision promotes reducing potable water use because treating water to drinking standards requires significant energy and resources, and conserving it preserves this finite resource for essential human needs.

What is the Envision approach to waste management during construction?

Answer: Minimize waste generation, maximize diversion from landfills through recycling and reuse

Envision promotes construction waste reduction at the source, diverting materials from landfills through recycling, reuse, and repurposing, and tracking waste metrics.

How does Envision define 'sustainable procurement'?

Answer: Selecting materials and services that minimize environmental impact and support responsible supply chains

Sustainable procurement involves evaluating suppliers and materials based on environmental and social criteria, including responsible sourcing, reduced environmental impact, and ethical supply chain practices.
