When calculating materials costs for some of the MR credit calculations, what is the potential
benefit of using the actual materials costs vs. the default 45% materials cost?(choose 2)
A: It is easier to break out the material costs from labor and equipment
B: It streamlines the documentation process
C: It becomes easier to earn an Innovation in Design point for exemplary performance
D: Projects with less than 45% materials cost can achieve credit thresholds more easily

参考答案: CD

Notes:

LEED allows a 45% default materials cost to be used. For example, if the project cost is
$10,000,000, the value of materials used on the project can be assumed to be $4,500,000.


Let\'s look at an example for MR Credit 5


Given a $10,000,000 project cost

The actual local materials used total: $1,500,000

The actual materials cost used is: $3,000,000

The default value of materials used is $10,000,000 X 0.45 = $4,500,000

% of local materials = Total Cost of Local Materials / Total Cost of Materials


Using the actual materials cost = $1,500,000 / $3,000,000 = 50% local materials


Using the default materials cost = $1,500,000 / 4,500,000 = 33% local materials


As you can see, when the actual materials cost is less than 45% of the project cost, a greater
threshold can be achieved. Because the thresholds are greater, it is easier to achieve both the credit
and an ID point by meeting the next threshold. In this example, by using the 45% default value the
project earned MR Credit 5.2. Using the actual costs, the project earned MR Credit 5.2 and one ID
point for using more than 40% regional materials.


{It is easier to break out the material costs from labor and equipment} incorrect because it is
often more difficult to break out the materials costs (that is why a 45% default material cost is
allowed).


{It streamlines the documentation process} is incorrect because calculating actual materials cost
will result in more paperwork by keeping track of all the receipts.
