MR (Material & Resources) Flashcards
Which qualifying products must always be included in MR credits?
Ceiling tiles, Interior paint, Cabinets and casework
For MR Prerequisite Storage and Collection of Recyclables at least two of which three items must have safe collection, storage, and disposal?
Two of the following three need to include safe collection, storage, and disposal:
Batteries
Mercury-containing lamps
Electronic waste
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?
The project team can pursue Option 3 Building and Material Reuse.
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.
A project team is reviewing a new insulation material that is Cradle to Cradle v3 Gold certified. If they use this product on the project what credits would it contribute to?
MR Credit Building Product Disclosure and Optimization - Material Ingredients, Option 1 Material Ingredient Reporting and MR Credit Building Product Disclosure and Optimization - Material Ingredients, Option 2 Material Ingredient Optimization
Cradle to Cradle products (depending on the level) can be applied to both the disclosure and optimization options of MR Credit Building Product Disclosure and Optimization - Material Ingredients.
For Option 1 the product must has been certified at the Cradle to Cradle v2 Basic level or Cradle to Cradle v3 Bronze level.
For Option 2 the following are accepted: Cradle to Cradle v2 Gold Cradle to Cradle v2 Platinum Cradle to Cradle v3 Silver Cradle to Cradle v3 Gold or Platinum
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
Formation of tropospheric ozone
Depletion of nonrenewable energy resources
A reduction below the industry average in at least three categories
For Option 2 Optimization of MR Credit Building Product Disclosure and Optimization – EPDs, a reduction below industry standards is required in at least three categories.
Note that for Option 2 the product must have an industry wide (generic) EPD or Type III EPD.
A project includes FSC certified wood costing $150,000 and that was extracted, manufactured, and purchased 80 miles (128 km) from the project site. What value does the wood have toward MR Credit Building Product Disclosure and Optimization - Sourcing of Raw Materials?
$300,000. Within 100 miles, 200%
A chair has the following components, weight percentages, and sustainability criteria:
Cotton fabric 5% certified by Rainforest Alliance
Plastic seat 30% none
Steel frame 65% 40% pre-consumer recycled content
The chair cost $100
What is the total product value as it applies to Building Product Disclosure and Optimization credit?
The product value is based on the weight of the components that meet the sustainability criteria as a percent of the total product weight.
Total product cost ($) X % product component by weight X (%) meeting sustainable criteria
$100 X 5% X 100% = $5
$100 X 30% X 0% = $0
$100 X 65% X 40% = $26
= $31
If a project team cannot meet the compliance thresholds in enough product categories for low-emitting materials, which action should the team take next?
Use the budget calculation method for all relevant products
If a project can’t comply with the product/category thresholds, Option 2 can be used.
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?
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.
Which type(s) of EPD is(/are) always created from a product category rule?
A product-specific Type III EPD
A construction waste-management plan must establish diversion goals, target at least how many materials to be diverted, and explain diversion plans for those materials?
Five (5) material streams must be identified in the plan for diversion.
Because the requirements for selecting products that qualify for building product disclosure and optimization are not typical of all construction teams and suppliers, which actions should be taken to ensure products meet the credit requirements?
Conduct a LEED-specific pre-construction meeting to review the credit requirements in detail and stress their importance
This is recommended to successfully earn the credits.Collect documentation of environmental claims for each product expected to contribute toward credit achievement and track each item purchased in the LEED MR offline calculator
This should be done to track purchases through construction.
A project located in a rural area without a recycling program must take which action for MR Prerequisite Storage and Collection of Recyclables?
Provide storage for recyclables to allow for participation in a future recycling service, should one be established
The prerequisite applies to all projects even if recycling is not currently available in the area.
For MR Credit Building Product Disclosure and Optimization - Environmental Product Declarations, the EPD must be consistent with ISO standards and be at least which assessment in scope?
Cradle-to-Gate
A project team is purchasing salvaged bricks from a local company that sourced the bricks from local buildings that are scheduled for demolition. The price of the bricks was $5,000. The delivery fee is $200 and the installation will cost $2,000. The owner received a 10% off discount by paying within 15 days.
What should the project team use as the cost of the materials for Materials Reuse as it applies to MR Credit Building Product Disclosure and Optimization - Sourcing of Raw Materials?
Under Leadership Extraction Practices, Materials reuse is valued at 100% of the cost of the material.
In the calculation of cost for a salvaged item found off-site any discount has to be reflected in the price as well.
Taxes and delivery are included in the cost, but equipment and labor is excluded.
$5,000 + $200 - 10% discount = $4,680
