ENV SP Sustainable Design Practices 2 — Questions and Answers
Question 1: Under the Envision framework, which credit category addresses reducing the environmental impact of materials used in infrastructure projects?
- Quality of Life
- Resource Allocation (Correct answer)
- Natural World
- Leadership
Correct answer: Resource Allocation
Resource Allocation is the Envision credit category focused on reducing resource consumption including materials, energy, and water.
Question 2: What design strategy involves using the natural topography and hydrology of a site to manage stormwater without traditional gray infrastructure?
- Bioretention design
- Green infrastructure
- Low impact development (Correct answer)
- Nature-based solutions
Correct answer: Low impact development
Low Impact Development (LID) uses site design techniques that mimic natural hydrology to manage stormwater at the source.
Question 3: A project team is selecting pavement materials for a roadway. Which factor is MOST aligned with Envision sustainable design principles?
- Lowest initial cost
- Highest compressive strength
- Recycled content and end-of-life recyclability (Correct answer)
- Fastest installation time
Correct answer: Recycled content and end-of-life recyclability
Envision promotes selecting materials with recycled content and recyclability to reduce resource consumption and waste.
Question 4: Which approach BEST demonstrates integrated design in sustainable infrastructure projects?
- Each discipline completes its design independently before review
- Stakeholders are consulted only during the public comment period
- Interdisciplinary teams collaborate from project inception through delivery (Correct answer)
- The owner approves all design decisions before engineers begin work
Correct answer: Interdisciplinary teams collaborate from project inception through delivery
Integrated design requires interdisciplinary collaboration starting at project inception to optimize sustainability outcomes across all systems.
Question 5: In the context of Envision, what does 'resilience' primarily refer to in sustainable design?
- The ability of a structure to resist seismic forces
- The capacity of infrastructure to absorb disturbance and recover function (Correct answer)
- The use of redundant mechanical systems
- The financial robustness of the project budget
Correct answer: The capacity of infrastructure to absorb disturbance and recover function
Envision defines resilience as the capacity of infrastructure to anticipate, absorb, adapt to, and recover from disturbances.
Question 6: What is the primary purpose of a life-cycle assessment (LCA) in sustainable design?
- To estimate the project's total construction cost
- To evaluate environmental impacts across a product or system's full life span (Correct answer)
- To determine the service life warranty of materials
- To schedule maintenance intervals for infrastructure assets
Correct answer: To evaluate environmental impacts across a product or system's full life span
LCA evaluates environmental impacts from raw material extraction through end-of-life disposal to inform more sustainable design choices.
Question 7: Which Envision credit specifically rewards projects that restore or enhance the functions of natural systems affected by construction?
- QL1.1 Improve Community Quality of Life
- NW3.1 Protect Wetlands and Surface Water (Correct answer)
- RA2.1 Reduce Operational Energy Consumption
- LD1.1 Provide Effective Leadership
Correct answer: NW3.1 Protect Wetlands and Surface Water
NW3.1 Protect Wetlands and Surface Water rewards efforts to avoid impacts and restore the functions of wetland and aquatic systems.
