试卷: LEED GA模拟题A[查看]
Energy efficiency is defined as:
A: Any strategy that reduces resource use 20% from a baseline comparison
B: Any strategy that reduces resource use 10% or more from a baseline comparison
C: The use of technology that requires less energy to perform the same function as a conventional item
D: The replacement of any older building product with a newer building product

参考答案: C

本题解释:
No specific percentages define if a product is more energy efficient than another;No specific percentages define if a product is more energy efficient than another;A compact fluorescent light bulb that uses less energy than an incandescent bulb to produce the same amount of light is an example of energy efficiency. The decision to replace an incandescent light bulb with a compact fluorescent is an example of energy conservation;Newer building products are not necessarily more energy efficient. Doors are a good example. A door from 100 years ago was probably solid wood. A new door might be a wood frame with steel veneer and a Styrofoam core. The old door may have greater insulating properties.
