Add the following to end of first paragraph:For commingled recycling the average annual recycling rate for a sorting facility is acceptable for recording diversion rates only when the facility\'s method of recording and calculating the recycling rate is regulated by a local or state government authority.

Requirements
Recycle and/or salvage nonhazardous construction and demolition debris. Develop and implement a construction waste management plan that, at a minimum, identifies the materials to be diverted from disposal and whether the materials will be sorted on-site or comingled. Excavated soil and land-clearing debris do not contribute to this credit. Calculations can be done by weight or volume, but must be consistent throughout. The minimum percentage debris to be recycled or salvaged for each point threshold is as follows:

Cost estimates for this credit
On each BD+C v4 credit, LEEDuser offers the wisdom of a team of architects, engineers, cost estimators, and LEED experts with hundreds of LEED projects between then. They analyzed the sustainable design strategies associated with each LEED credit, but also to assign actual costs to those strategies.
Our tab contains overall cost guidance, notes on what “soft costs” to expect, and a strategy-by-strategy breakdown of what to consider and what it might cost, in percentage premiums, actual costs, or both.
This information is also available in a full PDF download in The Cost of LEED v4 report.

LEED Interpretation
Inquiry:
Is a campus-like approach for MRc2 acceptable for two LEED-NC v2009 registered projects each pursuing one-off certification? Space is limited on the urban site for recycling dumpsters, therefore the best approach for CWM may mean that waste and recycling for all LEED registered projects will need to be aggregated and tracked together. AGMBC Master Site / Campus is not utilized, yet we propose using the AGMBC precedent for MRc2 documentation. We propose to track together all demolition, construction waste/diverted, & land clearing material for the project and then apply a weighted average based on GSF to each LEED project.
Ruling:
The applicant has requested to use a weighted average approach for Materials and Resources Credit 2 Construction Waste Management for several buildings that are pursuing one-off LEED Certification under LEED BD&C. Yes, the project may utilize a weighted approach based on gross floor area to determine the total construction waste for each building pursuing certification. For each LEED BD&C Building, the project team will be required to identify the materials that are diverted from disposal and provide calculations documenting the diversion rate. Each building must meet the required threshold for waste diversion in order to earn the credit. In addition, the Construction Waste Management (CWM) Plan must outline goals for diversion for each building, not just as an aggregate across all projects. Note that if the waste is comingled and sorted offsite, the project may follow the requirements outlined in LEED Interpretation 3000 for determining and documenting the diversion rate. This ruling addresses only projects pursing LEED Certification under the BD&C Rating Systems and does not set any precedent or guidelines for projects pursuing certification under different LEED Rating Systems.

LEED Interpretation
Inquiry:
The proposed project site is located on a military base that has potentially unexploded ordnance on-site.Protection from potential detonation during construction is required by the federal government to shield pedestrians and existing housing across the street from the project site. As a part of the project, a detonation barrier is to be constructed prior to start of excavation. This barrier can be built using various material but must have substantial foundations and structural strength to withstand large explosion forces. After construction is completed, the detonation barriers would be deconstructed to allow access to the site.The project team is proposing to incorporate salvaged local material into the design of these barrier walls. May the salvaged material qualify for MR credit 2 Construction Waste Managementif recycled after deconstruction?
Ruling:
The project team has inquired whether materials used for a temporary (during construction) detonation barrier can be included within the construction waste management materials diverted since it is mandated to be built. If the temporary detonation barrier is recycled or salvaged after deconstruction, it meets the intent of MR Credit 2 (diversion from landfill and incineration) and may contribute towards construction waste management.
