ENV SP Resource Allocation & Materials 2

Question 1

In the Envision framework, which credit category specifically addresses the efficient use of materials and resources during construction?

Accepted Answer

Resource Allocation

Answer

The Resource Allocation credit category in Envision covers materials efficiency, waste reduction, and sustainable sourcing during project delivery.

Question 2

Which strategy best supports a circular economy approach in infrastructure material selection?

Accepted Answer

Designing for disassembly and material recovery at end-of-life

Answer

Designing for disassembly allows materials to be recovered and reused, which is the core principle of a circular economy.

Question 3

A project team wants to reduce embodied carbon in structural steel. Which approach is MOST effective?

Accepted Answer

Specifying steel with high recycled content from electric arc furnace production

Answer

Electric arc furnace steel uses recycled scrap and produces significantly lower embodied carbon than blast furnace virgin steel.

Question 4

What does 'fly ash' serve as in sustainable concrete mix design?

Accepted Answer

A supplementary cementitious material that partially replaces Portland cement

Answer

Fly ash, a coal combustion byproduct, replaces a portion of Portland cement, reducing CO₂ emissions and using an industrial waste stream.

Question 5

Which metric is used to compare the environmental impact of different materials across their full life cycle?

Accepted Answer

Global warming potential (GWP) from a life cycle assessment (LCA)

Answer

GWP quantified through LCA allows apples-to-apples comparison of the carbon footprint of different material choices over their entire lives.
