The Materials and Resources Credit, Building Product Disclosure and Optimization - Sourcing of Raw Materials rewards projects that use materials that have optimized extraction processes by limiting or eliminating the extraction of new resources, the reuse of materials or the use of recycled materials1. According to the LEED Reference Guide for Building Design and Construction2, the credit has two options: Option 1. Raw Material Source and Extraction Reporting and Option 2. Leadership Extraction Practices. Option 1 requires the project to use at least 20 permanently installed products from at least five different manufacturers that have publicly released a report from their raw material suppliers which include extraction locations, a commitment to long-term ecologically responsible land use, a commitment to reducing environmental harms from extraction and/or manufacturing processes, and a commitment to meeting applicable standards or programs voluntarily that address responsible sourcing criteria2. Option 2 requires the project to use products that meet at least one of the responsible sourcing criteria below for at least 25%, by cost, of the total value of permanently installed building products in the project:
* Extended producer responsibility. Products purchased from a manufacturer (producer) that participates in an extended producer responsibility program or is directly responsible for extended producer responsibility.
* Bio-based materials. Bio-based products must meet the Sustainable Agriculture Network's Sustainable Agriculture Standard. Bio-based raw materials must be tested using ASTM Test Method D6866 and be legally harvested, as defined by the exporting and receiving country. Exclude hide products, such as leather and other animal skin material.
* Wood products. Wood products must be certified by the Forest Stewardship Council or USGBC- approved equivalent.
* Materials reuse. Reused products must include salvaged, refurbished, or reused products.
* Recycled content. Recycled content is the sum of postconsumer recycled content plus one-half the preconsumer recycled content, based on cost. Products meeting recycled content criteria are valued at
100% of their cost for the purposes of credit achievement calculation.
* USGBC approved program. Other USGBC approved programs meeting leadership extraction criteria.
Therefore, among the given options, only Option A is relevant to the use of reused/salvaged materials or recycled content, as they can contribute to the materials reuse or recycled content criteria under Option
2. Option B is a prerequisite that requires the project to develop and implement a construction and demolition waste management plan that identifies the materials to be diverted from disposal and whether the materials will be sorted on-site or co-mingled2. Option C is a credit that requires the project to use at least 20 different permanently installed products from at least five different manufacturers that use any of the following programs to demonstrate the chemical inventory of the product to at least 0.1% (1000 ppm):
* Health Product Declaration. The end use product has a published, complete Health Product Declaration with full disclosure of known hazards in compliance with the Health Product Declaration Open Standard.
* Cradle to Cradle. The end use product has been certified at the Cradle to Cradle v2 Basic level or Cradle to Cradle v3 Bronze level.
* REACH Optimization. The end use product is compliant with REACH Optimization criteria.
* GreenScreen v1.2 Benchmark. The product's chemical ingredients are inventoried using the GreenScreen v1.2 Benchmark.
* Declare. The Declare product label must indicate that all ingredients have been disclosed down to 1000 ppm.
Option D is a credit that requires the project to use at least 20 different permanently installed products that have environmental product declarations. The products must be sourced from at least five different manufacturers. The environmental product declarations must conform to ISO 14025, 14040, 14044, and EN

NEW QUESTION # 37
Which system is eligible for the Energy and Atmosphere Credit, Renewable Energy Production?
- A. Tidal-based electrical production
- B. Municipal solid waste combustion
- C. Passive solar and daylighting strategies
- D. Ground-source heat pumps
Answer: A
Explanation:
Explanation
Tidal-based electrical production is eligible for the Energy and Atmosphere Credit, Renewable Energy Production. This credit rewards projects that use renewable energy systems to offset building energy cost.
According to the LEED v4 BD+C Reference Guide, renewable energy systems are defined as "those that use resources that are naturally replenished within a 100-year or shorter cycle and that are greenhouse gas neutral on an annual basis" 1. Tidal-based electrical production meets this definition, as it uses the kinetic energy of the tides to generate electricity without emitting greenhouse gases. The other options are not eligible for this credit, as ground-source heat pumps are not considered renewable energy systems, municipal solid waste combustion is not greenhouse gas neutral, and passive solar and daylighting strategies do not offset building energy cost.References: LEED v4 BD+C Reference Guide, Energy and Atmosphere Category, EAc Renewable Energy Production, page 572.
NEW QUESTION # 38
In the energy modeling of a building envelope, which of the following U-values should be considered as an assembly U-value?
- A. Glass
- B. Wall
- C. Steel
- D. Concrete
Answer: B
Explanation:
The assembly U-value of a building envelope component is the overall rate of heat transfer through that component, taking into account the different materials and layers that make up the component. For example, the assembly U-value of a wall would include the effects of the insulation, framing, sheathing, cladding, air films, etc. The assembly U-value is different from the material U-value, which is the rate of heat transfer through a single material. For example, the material U-value of steel is much higher than the material U-value of glass, but the assembly U-value of a steel-framed window may be lower than the assembly U-value of a glass curtain wall, depending on the other factors involved.
