Materials and Resources Flashcards
Material and Resources Intent
Encourage buildings to reduce, reuse, and recycle. In LEED B4 MR credits emphasize transparency regarding the composition of building materials, and require actions that support a life-cycle approach to embodied impact reduction.

Storage and Collection of Recyclables Prerequisite
Purpose: Reduce waste in landfills.
Requirements: At a minimum, recycle: metal, glass, mixed paper, plastic and corrugated cardboard.
Notes: should make efforts for safe collection, storage and disposal of two of the following: Batteries, mercury-containing lamps (CFLs or fluorescent tubes, T5s, T8s, T12s) and electronic waste.
Construction Waste and Demolition Waste Management Planning Prerequisite
Purpose: Reduce construction and demolition materials waste in landfills through recycling, reuse and recovery.
Requirements: Develop and implement a construction and demolition waste management plan and define waste diversion goals for the project by identifying at least five building materials. (both structural and non structural) to divert from landfills. Specify whether materials will be separated or commingled.
Building Life-Cycle Impact Reduction Credit
Purpose: To reuse existing building materials and/or emphasizing materials reduction through lifecycle assessment of building materials.
1) Historic building re-use (5points)
2) Renovation of Abandoned or blighted building (5 points)
3) Building and material reuse (2-4 points)
4) Whole building life cycle assessment (3 points)
Note: reuse 95% of the building in option 3; or achieve any improvement over the required credit thresholds in all six (6) impact categories.
Building Product Disclosure and Optimization (BPDO) - Environmental Product Declarations
Purpose: To reduce greenwashing by rewarding choice of products and materials for which life-cycle information is available, while encouraging manufacturers to provide verified improved environmental life cycle impacts for their products.
Requirements: 1) Environmental Product Declarations: choose 20 products (from 5 different manufacturers) that offer EPD or 2) Multi Attribute Optimization: Use products with MAO for 50%, by cost, of the total value of permanently installed projects in the site.
Notes: Product Claim Validations, Certifications, and Standards are related concepts, but they are not the same. Validation of a product’s attributes simply confirm a product’s claim. Certification is a more rigorous form of validation. Certification rely on established standards, such as ANSI and ISO.
MA labels (certifications) offer more comprehensive review of products and their makeup than Single Attribute (SA) labels (certifications). MA labels are offered from organizations such as EcoLogo. An example of a SA certification would be the Forest Stewardship Council (FSC). EPDs are available from organizations such as UL Environment.
USGBC/LEED views “industry wide” EPDs to be worth 1/2 of a product. “Product Specific” EPDs are valued as 1 whole product.
USGBC rewards regional products by encouraging use of products that are sourced within 100 miles of the project site by valuing them at 200% of their contributing cost.
EP Option 1 needs to source at least 40 qualifying products from 5 manufacturers. Option 2 Purchase 75% by cost, or permanently installed building products that meet the required attributes.
BPDO Sourcing of Raw Materials Credit
Purpose: Reduce greenwashing by rewarding choice of products and materials for which life-cycle information is available, while encouraging manufactures to disclose the sources of raw materials and provide verified improved environmental life cycle impacts for their products.
Requirements: 1) “Raw Materials Source Reporting” which use at least 20 different products from 5 separate manufacturers that disclose supplier extraction locations and commit to responsible land use or 2) “Leadership Extraction Practices” which uses at least 25%, by cost, of total value of permanently installed building products that comply with 1 of the following categories.
Extended Producer Responsibility
- Products purchased from a manufacturer who participates in an extended producer responsibility program or is directly responsible for their extended producer responsibility.
Bio-Based Materials
- Product must meet the Sustainable Agriculture Network’s Sustainable Agriculture Standard. Raw materials must be tested using ASTM test method D6866.
Wood Products
-Wood products must be certified by the forest stewardship council (FSC)
Materials Reuse
-Includes salvaged, refurbished or reused products.
Recycled Content: Post-consumer content + 1/2 pre-consumer content.
USGBC approved program.
Biobased materials (AKA rapidly renewable in LEED 2009) are now required to meet the Sustainable Agriculture Standard to comply with certain MR credits in LEED V4.
EP Option 1 must source at least 40 products from 5 manufacturers or Option 2 must purchase 50%, by cost, of the total value of permanently installed building products that meet the responsible extraction criteria.
BPDO Material Ingredients
Purpose: Same as other BPDOs, but by disclosing material ingredients to verify improved lifecycle of their products.
Requirements: 1) “Material Ingredient Reporting” use 20 different products from 5 manufacturers who provide a “chemical inventory” or 2) Material Ingredient Optimization use products valued at least 25%, by cost, of total permanent building materials.
Notes:
1) Chemical Abstract Service Registration Number (CASRN)
2) Health Product Declaration (HDP): Disclosure objective information about ingredients in building products and provides information about potential health hazards associated with the ingredients. An HPD is more about disclosure than performance.
3) Cradle to Cradle Certification: A process for managing materials that emphasizes recycling and reuse at the end of a product or material’s life, rather than disposal. Product that are C2C certified may qualify for contributing to MR credits in LEED V4.
EP Option 1 uses 40 permanently installed building products that meet credit criteria.
Option 2 Purchase at least 50%, by cost, of permanently installed building product that meet the credit criteria.
Construction Demolition Waste Management Credit
Purpose: Reduce construction and demolition material waste in landfills beyond prerequisite levels.
Requirements: Diversify material streams. 1) Divert at least 50% of three streams, or 75% of four streams for 1 or 2 points. 2) No more than 2.5lbs or construction waste is generated per SF of building floor area.
EP for teams that achieve both options 1 and 2.
Notes:
LEED V4 MR credit category includes certain specifications for buildings certified under LEED for healthcare. LEED V4 for Healthcare reduces the instance of any bio accumulative, persistent, or toxic chemicals in healthcare settings. Such materials include Mercury, cadium, lead and copper.
LEED V4 MR reduces the use of any furnishings, especially in healthcare environment, for which chemical component and ingredient transparency is not available.
