An office renovation project is working to reuse materials in the project. The total materials cost of the project is estimated to be $2.3 million dollars. The project used the following items:
Item ;Cost
Interior Doors rehung in new locations ; Cost $10,000;
Salvaged Brick ; Cost $89,000;
Salvaged Wood ; Cost$30,000;
Cabinet Hardware ; Cost $5,000;
What percentage of material is applicable to Materials and Resources Credit, Materials Reuse?

A: 5.8%
B: 5.4%
C: 5.2%
D: 4.5%

参考答案: A

本题解释:
See MR Credit 3 Implementation.

For MR Credit 3 materials that are ‘fixed’ must be reused in a different way or in a new location from their original use to contribute to this credit. The doors can be included even though they are still being used as doors because they have been moved to a new location.

The cabinet hardware can be included because they are components that retain and continue to serve their original function.

So the calculation should include:

$10,000 + $89,000 + $30,000 + $5,000 = $134,000

Then divide by the total materials cost. $134,000/$2,300,000 = 5.8%
