"None" "None" "LEED Interpretation" "5481" "2003-12-01" "New Construction" "Are the calculations for MR Credit 5.2 based on the total amount of regionally manufactured materials that a project team has claimed for MR Credit 5.1 (thus making the performance requirement a ""moving target""), or should project teams use the minimum 20% requirement of MR Credit 5.1 as the benchmark, and thus the numerator of Equation 2 in the LEED Reference Guide? " "This ruling provides additional clarification to a previous CIR (10/18/01). The latter option stated in the inquiry is correct. To have a consistent and comparable performance standard for all LEED projects, the requirement for MR Credit 5.2 is 50% of the minimum 20% benchmark needed for achieving MR Credit 5.1. Thus, in essence, the threshold for MR Credit 5.2 is 10% of the total materials cost. Only raw materials used for the items in Credit 5.1 can be included in Credit 5.2 (as per credit requirements language). When considering Innovation points for exceptional performance, MR Credits 5.1 and 5.2 are considered independently. As a result, the normal approach of exceeding the next logical level of performance applies, and individual Innovation points may be achieved for demonstrating that 40% or more of materials cost is locally manufactured and 20% or more of materials cost is locally harvested.

" "None" "None" "X" "LEED Interpretation" "5564" "2004-07-19" "New Construction" "For Materials and Resources Credits 3 through 6, the calculation is based on the cost of all construction materials and products as a percentage of the total cost of all materials for the project. Material cost excludes installation (e.g. equipment and labor). Our question is regarding the cost of formwork used during construction. Should this be included as part of the material costs of the project even though it is not permanently installed in the building? Or would it be acceptable to consider it an equipment cost and therefore excluded from the total material cost of the project? What are the implications for resource reuse and local/regional materials points? " "As formwork (rented or purchased for the project) is not a permanently installed material, it is considered as ""equipment"" for all MR credits except MR c7 and thus not included in the material costs of the project. For MRc7, all non-rented temporary wood formwork must be included in the denominator of the credit calculations and the FSC-certified non-rented temporary wood formwork should be included in the numerator.
