CID Materials and Sustainability 3 — Questions and Answers
Question 1: Which flooring material is naturally antimicrobial and made from renewable cork oak bark?
- Cork (Correct answer)
- Vinyl
- Laminate
- Ceramic
Correct answer: Cork
Cork is harvested from bark, is renewable, and has antimicrobial properties.
Question 2: What does 'embodied energy' of a material refer to?
- Total energy used to extract, process, and transport it (Correct answer)
- Energy it saves during use
- Its electrical conductivity
- Its thermal mass
Correct answer: Total energy used to extract, process, and transport it
Embodied energy is all energy consumed to produce and deliver a material.
Question 3: A designer specifies carpet tiles instead of broadloom partly for sustainability. Why?
- Individual damaged tiles can be replaced, reducing waste (Correct answer)
- They are always cheaper
- They never stain
- They require no adhesive ever
Correct answer: Individual damaged tiles can be replaced, reducing waste
Carpet tiles allow spot replacement, minimizing waste compared to full replacement.
Question 4: Which certification specifically targets water-efficient plumbing fixtures?
- WaterSense (Correct answer)
- GREENGUARD
- Cradle to Cradle
- FSC
Correct answer: WaterSense
EPA's WaterSense label identifies water-efficient fixtures.
Question 5: GREENGUARD certification primarily ensures a product meets standards for:
- Low chemical emissions (Correct answer)
- Fire resistance
- Structural load
- Recyclability only
Correct answer: Low chemical emissions
GREENGUARD certifies products for low chemical emissions and better indoor air.
Question 6: Which of the following is a rapidly renewable textile fiber?
- Wool (Correct answer)
- Polyester
- Nylon
- Acrylic
Correct answer: Wool
