ENV SP Sustainable Design Practices 3 — Questions and Answers
Question 1: Which sustainable design strategy involves designing a facility so components can be disassembled and materials recovered at end of life?
- Adaptive reuse
- Design for disassembly (Correct answer)
- Modular construction
- Prefabrication
Correct answer: Design for disassembly
Design for disassembly enables material recovery and reuse at end of life, supporting circular economy principles valued in Envision.
Question 2: A highway project in an arid region adopts drought-tolerant native plantings for its right-of-way. Which Envision benefit does this MOST directly achieve?
- Reduced construction schedule
- Reduced water consumption and support for local biodiversity (Correct answer)
- Improved noise attenuation for nearby residents
- Increased pavement structural capacity
Correct answer: Reduced water consumption and support for local biodiversity
Native drought-tolerant plantings reduce irrigation water needs and support local ecosystems, addressing both Resource Allocation and Natural World credits.
Question 3: What does the Envision framework call the highest achievement level for a credit?
- Exemplary
- Superior
- Conserving
- Restorative (Correct answer)
Correct answer: Restorative
Restorative is the highest Envision achievement level, indicating the project restores conditions beyond the baseline rather than just minimizing harm.
Question 4: Which principle of sustainable design emphasizes locating infrastructure to avoid sensitive ecological areas before applying mitigation measures?
- Pollution prevention
- Mitigation hierarchy (Correct answer)
- Ecological offset
- Green certification
Correct answer: Mitigation hierarchy
The mitigation hierarchy prioritizes avoidance first, then minimization, then mitigation, and finally offsetting as a last resort.
Question 5: A wastewater treatment plant is redesigned to recover biogas for on-site energy. This BEST exemplifies which sustainable design concept?
- Demand-side management
- Industrial symbiosis
- Resource recovery (Correct answer)
- Zero liquid discharge
Correct answer: Resource recovery
Resource recovery converts a waste stream (biogas from sludge digestion) into a useful energy input, reducing both waste and energy demand.
Question 6: In sustainable infrastructure design, what is the role of a 'heat island effect' analysis?
- To size HVAC systems for peak summer loads
- To quantify how surface materials and vegetation affect local air temperatures (Correct answer)
- To determine the earthquake hazard at a project site
- To calculate solar panel output for a facility
Correct answer: To quantify how surface materials and vegetation affect local air temperatures
Heat island analysis evaluates how paving, roofing, and vegetation choices influence local temperatures, informing design decisions that reduce urban warming.
Question 7: Which of the following BEST describes the concept of 'net zero water' in sustainable design?
- A project that uses no water in its operations
- A project that balances water withdrawals with water returned to the same watershed (Correct answer)
- A project that captures 100% of stormwater on site
- A project that eliminates all impervious surfaces
Correct answer: A project that balances water withdrawals with water returned to the same watershed
Net zero water means the project withdraws no more water from the watershed than it returns, achieved through conservation and on-site water management.
