试卷: LEED v4 ID+C模拟题C卷英文[查看] A material with a potential life of 30 years that is intentionally designed to last only 15 years is an example of: A: Differential durability B: Refurbishing C: Premature obsolescence D: Take-back material 参考答案: C
本题解释: Notes:A:Differential durability is state in which two materials with different life spans make up one complete component. If one material wears out and cannot be separated and replaced, the entire product must be thrown away.B:A refurbished material is an item that has completed its life cycle and is prepared for reuse without substantial alteration of its form. Refurbishing involves renovating, repairing, restoring, or generally improving the appearance, performance, quality, functionality, or value of a product.C:Premature obsolescence is the wearing out or disuse of components or materials whose service life exceeds their design life. For example, a material with a potential life of 30 years is intentionally designed to last only 15 years, such that its remaining 15 years of service is potentially wasted. In contrast, components whose service life is the same as their expected use are utilized to their maximum potential.D:A take-back material or program is where a manufacturer takes-back the material at the end of its useful life for recycling or reuse. |
