Industrial and Product Design Industrial and Product Design Sustainability & Environmental Design 1 — Questions and Answers
Question 1: What does 'lifecycle assessment' (LCA) evaluate in product design?
- The financial return on investment
- Environmental impacts across a product's entire life from raw material to disposal (Correct answer)
- The number of product revisions made
- Consumer satisfaction ratings over time
Correct answer: Environmental impacts across a product's entire life from raw material to disposal
LCA is a systematic analysis of environmental impacts across all stages of a product's life, including material extraction, manufacturing, use, and end-of-life.
Question 2: Which design philosophy aims to eliminate waste by keeping materials and products in use as long as possible?
- Linear economy design
- Circular economy design (Correct answer)
- Value engineering
- Design for disassembly
Correct answer: Circular economy design
Circular economy design aims to close material loops through strategies like repair, reuse, remanufacturing, and recycling to eliminate waste.
Question 3: In eco-design, what does 'design for disassembly' (DfD) prioritize?
- Making products harder to open
- Enabling easy separation of components for repair, reuse, or recycling at end of life (Correct answer)
- Reducing the number of product colors
- Maximizing the use of adhesives
Correct answer: Enabling easy separation of components for repair, reuse, or recycling at end of life
DfD ensures product components can be easily separated and sorted at end of life, enabling efficient repair, part reuse, and material recycling.
Question 4: Which of the following is an example of 'dematerialization' in product design?
- Adding more features to a product
- Replacing a physical music CD with a digital download (Correct answer)
- Using heavier materials for durability
- Increasing product packaging
Correct answer: Replacing a physical music CD with a digital download
Dematerialization reduces material use by replacing physical products or components with digital equivalents or lighter-weight alternatives.
Question 5: What is the primary goal of 'biomimicry' in industrial design?
- Using only biological materials
- Drawing inspiration from nature's strategies to solve design challenges sustainably (Correct answer)
- Designing products that look like animals
- Replacing engineers with biologists
Correct answer: Drawing inspiration from nature's strategies to solve design challenges sustainably
Biomimicry applies nature's time-tested patterns and strategies to solve human design challenges, often resulting in more sustainable and efficient solutions.
Question 6: In the US, which label program certifies that a product meets environmental standards for energy efficiency in electronics and appliances?
- Green Seal
- ENERGY STAR (Correct answer)
- LEED
- UL Environment
Correct answer: ENERGY STAR
ENERGY STAR is a US EPA program that certifies products meeting strict energy efficiency guidelines, helping consumers identify energy-saving products.
