1-Source reduction includes all EXCEPT which strategy? A. Donating materials
Donation, resale, or on-site reuse are ways to divert waste, not reduce it at the source.
2-Which materials are included in a whole-building life-cycle assessment? (Choose 3)
A. Roof assemblies C. Covered parking
F. Footings and foundation
This credit requires all that all assessed materials include the complete building envelope and structure elements. These include the following:
Footings Foundations Structural walls Interior wall cladding Structural floors Ceilings
Structural parking
Interior finishes, non-structural walls, furniture, and MEP are excluded.
3-What minimum time period must a waste stream audit be conducted for a retail project?
This is the minimum.
4- A general contractor is working on documenting the quantity of materials reuse for a project. If a salvaged material came from on-site, how will the contractor determine the replacement value of the material?
D. Using a comparable material in the local market, excluding labor and shipping
Material reuse is based on the total cost of the materials and the total cost of any reused/salvaged materials.
If a salvaged material came from on-site, the replacement value of the material is determined by comparing the material to something available in the local market. Labor and shipping are excluded, as are any discounts the seller may apply.
5- A project team is reviewing Type III EPDs for the impact reduction of different office chairs in the following categories:
Global warming potential (greenhouse gases) Depletion of the stratospheric ozone layer Acidification of land and water sources Eutrophication

Five (5) material streams must be identified in the plan for diversion.
8- A project will include carpet tile and walk-off mats from one manufacturer, as well as ceramic tile and wood flooring from another manufacturer. All of the products have industry-wide (generic) EPDs. How many permanently installed products would this count toward MR Credit Building Product Disclosure and Optimization - EPDs?
B. 2
It's necessary to know first what constitutes a product in LEED as it applies to these credits.
A product is defined by serving the distinct function. This includes the physical components and services needed to serve the intended function of the permanently installed building product. Similar products from the same manufacturer can be counted as separate products if they have distinct formulations, but not if there are aesthetic variations or reconfigurations.
In this question there are four distinct products from two different manufacturers. A product-specific declaration, which is made by a manufacturer but is a self- declaration, is valued at 1/4 of a product.
An industry-wide ISO-compliant generic EPD is valued as 1/2 of a product. A product-specific Type 3 EPD is valued as 1 product.
The item stem mentions four products, all of which have generic EPDs, so each counts as 1/2 of a product, or two total products.
9- A project team is conducting alternative analysis of a project design as part of a whole-building life-cycle assessment. One of the products the design team is
considering is not in the LCA tool's data set. Which option does the project team have for the analysis?
D. If the product has a critically reviewed LCA or EPD, the product's impact-measure results can be added to the model.
If an LCA or EPD is available, the product could be added into the software.
10- Which product would contribute to Option 2 Optimization of MR Credit Building Product Disclosure and Optimization - EPDs if the product demonstrates a reduction in at least three impact categories?
D. Carpet that is third-party certified
A product must be third-party certified to count for Option 2. By third-party certified, that means an industry wide (generic) EPD or a product-specific Type III EPD.
The product must be permanently installed.
The product must perform better than the industry average in at least 3 of 6 impact categories.
11- A project team is close to meeting the 25% threshold for building and material reuse for MR Credit Building Life-Cycle Impact Reduction. Which strategy would assist the project team earn the credit?
If the credit threshold isn't met, the project team could find more materials that would contribute to a greater surface area and count toward the area of reuse.
12- A project team has identified enough qualifying products to meet MR Credit Building Product Disclosure and Optimization - Sourcing of Raw Materials, Option 1 Raw Material Source and Extraction Reporting. What must be submitted for documentation of the credit?
C. The corporate sustainability reports from each manufacturer and the building disclosure and optimization calculator
13- For a product to count toward the achievement of MR Credit Building Disclosure and Optimization, Sourcing of Raw Materials, all EXCEPT which statement regarding
reporting must be true?
C. A report must be published within one year of the product's installation.
The report has to be current at the time of installation, not published within one year of installation.
14- A project team is considering options for earning MR Credit Construction and Demolition Waste Management Option 1 Diversion. The school is in a rural area with little waste infrastructure, and the project cannot meet the waste diversion
requirements through reuse and recycling. Which strategy should be considered? A. Use any wood waste as biofuel
Waste-to-energy is a viable option if reuse and recycling is not available.
15- A developer has purchased a blighted 100,000 SF (9,290 m2) warehouse. Part of the roof and one of the exterior walls, totaling 30,000 SF (2,787 m2), are structurally
unsound and must be demolished. The developer will maintain 60,000 SF (5,574 SF) of the surface area of the building. Which statement is true about the project team's ability to earn MR Credit Building Life-Cycle Impact Reduction?
For Option 2, projects are only allowed to exclude up to 25% of the surface area because of deterioration or damage. If more than 25% is considered unsound, the project cannot pursue Option 2.
Remember to start by looking at the percentage that is unsound to see if the credit can be pursued. Don't subtract the unsound portion from the total as a means of
determining if at least 50% of the area is maintained from that value.
16- A renovation project includes removing part of an old building, re-grading some of the site, and taking down some trees for a building expansion. What item must be included in the calculations for MR Credit Construction and Demolition Waste Management Option 1 Diversion?
B. Carpet that is not Green Label Plus certified
The carpet would need to be included in the calculations for the total of all construction waste management. If the carpet were recycled or donated it would be included in the percentage of construction waste diverted from landfills.
Notes:
Land-clearing debris is excluded from the calculations.
17- Which type of analysis will the project team conduct for a whole-building life-cycle assessment?
B. Cradle-to-grave
A cradle-to-grave analysis is used to compare a design case building to a baseline building.
18- A project team member was not clear about the specifications for building materials, and a contractor substituted a product with disclosure documentation for a product without disclosure documentation. The replacement product has a GreenScreen v1.2
Benchmark. How should the product be treated as it applies to MR Credit Building Product Disclosure and Optimization - Material Ingredients?
D. Exclude the product from the disclosure option and include it in the optimization option
Each Building Product Disclosure and Optimization credit has an option for disclosure and another option for optimization. Each option is worth 1 point, and projects can earn 2 points each for the credit.
Earning 1 point for Option 2 optimization is allowed without earning Option 1 disclosure for each credit.
In this scenario, the product does not have disclosure (because the product was
substituted), but it does have optimization by having the GreenScreen v1.2 Benchmark which counts toward Option 2.
19- A project will renovate a building with historic designation into new office space. The surface area of the existing building structure and envelope is 100,000 SF. How much of the existing building will need to be reused to earn 5 points for MR Credit Building Life- Cycle Impact Reduction?
A. There is no minimum
There is no threshold of compliance for Option 1 Historic Building Reuse. However any demolition can't result in the building losing it's historic status.
20- A project includes some salvaged wood flooring costing $50,000 and that was purchased 500 miles (804 km) from the project site. What value does the wood have toward MR Credit Building Product Disclosure and Optimization - Sourcing of Raw Materials?
The wood meets a sustainability criteria, but since it was purchased more than the 100 miles (160 km) from the project, it is valued at 100% (not 200%) of the cost.
See MR Overview Location Valuation Factor.
For a product to qualify for the location valuation factor two criteria must be met: 1. Sustainability
2. Extraction, manufacture, and purchase within the radius If the product isn't sustainable, it counts as 0%.
If the product meets multiple sustainability criteria, it doesn't count more toward the total (salvaged material that contains recycled content can't be double counted).
21- A project team is reviewing material choices before deciding which products to include. The team located interior wall partitions made with recycled content that have been salvaged from another building. The partitions are available from a company located 50 miles (80 km) from the project site for the price of $20,000. What value do the partitions have toward MR Credit Building Product Disclosure and Optimization - Sourcing of Raw Materials?
C. $40,000
See MR Overview Location Valuation Factor.
For a product to qualify for the location valuation factor, two criteria must be met: 1. Sustainability criteria
2. Extraction, manufacture, and purchase within the radius. If the product isn't sustainable, it counts as 0%.
If the product meets multiple sustainability criteria, it doesn't count more toward the total (salvaged material that contains recycled content can't be double counted). $20,000 X 200% location valuation factor = $40,000
22- Which type of project would require the project team to conduct a whole-building life-cycle assessment for MR Credit Building Life-Cycle Impact Reduction?
A. A new Core and Shell project
New buildings can only use Option 4 of the credit.
23- A project team has purchased 7,500 SF (696 m2) of salvaged wood flooring from a barn at a cost of $22,500. How can the reused materials be applied toward LEED credits?
B. The surface area of the flooring can be applied to MR Credit Building Life-Cycle Impact Reduction, Option 3 Building and Material Reuse; OR the cost of the flooring can be applied to MR Credit Building Product Disclosure and Optimization - Sourcing of Raw Materials, Option 2 Leadership Extraction Practices.
The reuse of off-site materials can be applied to only one credit. Building reuse uses surface area.
The optimization credit option uses cost or replacement value.
24- A project team is deciding if the project will generate more than 2.5 pounds of construction waste per square foot (12.2 kg/m2). MR Credit Construction and Demolition Waste Management Option 2 Reduction of Total Waste Material is appropriate if the project team is able to take which action?
D. Implement source reduction strategies in design and construction
Project teams choosing Option 2 need to use source reduction strategies to reduce the quantity of waste generated on site.
25- What documentation for MR Prerequisite Storage and Collection of Recyclables is specific to LEED BD+C: Retail?
A. Waste stream study
Retail projects require a waste stream audit conducted over a 24-hour period that must be documented.
26- Which is a key strategy for project teams to earn multiple points and credits for the MR Credits for Building Product Disclosure and Optimization?
C. Select materials that double count toward options and credits
Materials that have lots of documentation and sustainable attributes can count toward multiple credits.
For example in the EPD, credit Option 1 can be earned if materials have an EPD. Option 2 includes a performance requirement for reduction of the product's environmental impacts assessed.
27- A project team believes they can generate less than 2.5 pounds of construction waste per square foot (12.2 kg/m2) by using source reduction strategies such as modular components and prefabricated wall assemblies for the project. What will the project team need to document for MR Credit Construction and Demolition Waste Management Option 2 Reduction of Total Waste Material?
B. Total waste per area

30- A project has a cost of $21M. The cost of the optional products and materials (furniture and MEP) for the project is $500,000. Given this information, what is the default materials cost of the project?
B. $9,950,000
If the project team doesn't use the actual materials cost, a default materials cost of 45% of the total construction cost can be used. If optional products and materials are
included in the credit calculations, the actual value of those materials must be added to the default value.
$21,000,000 X 45% = $9,450,000 $9,450,000 + $500,000 = $9,950,000 See MR Overview Determining Product Cost.
