试卷: LEED AP ID+C 模拟试卷A[查看] A project team has purchased several workstations that contain pre and postconsumer content. The workstations cost $1,000 each and are made up of the following:
Material Content
100 lbs of steel 90% postconsumer;
30 lbs of plastic 50% postconsumer;
5 lbs Other;
What cost can the team attribute to recycled content for each workstation? A: $770 B: $110 C: $660 D: $900 参考答案: A
本题解释: Materials and Resources Credit Recycled Content, Calculations
To discover what part of materials cost can be attributed to the recycled material, the cost must be weighted.
Total weight is 135 lbs
100 lb steel X 90% post consumer = 90 lbs / 135 lbs = 66%
66% X $1,000 = $660
30 lbs plastic X 50% post consumer = 15 lbs / 135 lbs = 11%
11% X $1,000 = $110
Total cost of the recycled material is $770.00 |
