1. LEEDv4 Materials Resources
Helen Sanders,
SAGE Electrochromics, Inc.

2. LEED v4: Materials and Resources - Overview
Materials and Resources is one section of LEEDv4
Multiple credit areas within the section
Project teams can achieve points by complying with some or all of the credit areas
Intent:
Reward projects for reusing as much material as possible
Reward projects for optimizing the design to use less material overall
Life-cycle thinking on whole-building and product level

3. 2 Points available from 3 options
Credit Area: Building Product Disclosure and Optimization – Material Ingredients
Intent
To encourage the use of products that have
life-cycle information available
environmentally, economically , socially preferable life-cycle impacts.
To reward teams for selecting products which
Chemical ingredients inventoried using accepted methodologies
Verified to minimize the use and generation of harmful substances
To reward raw material manufacturers who produce products verified to have improved life-cycle impacts
2 Points available from 3 options

4. Option 1: Material Ingredient Reporting (1 pt)
Use at least 20 different permanently install products from at least 5 different manufacturers that demonstrate the chemical inventory of the product to at least 0.1% using one of:
HPD – published with full disclosure of known hazards
Cradle to Cradle (v2 basic level or v3 bronze level),
Declare (all ingredients evaluated and disclosed to 1000ppm)
Manufacturer Inventory (ingredient list by CAS #)
Furniture Sustainability standard
Cradle to Cradle Material Health Certificate (Bronze or higher and at least 90% of materials assessed by weight)
Material Ingredients

5. Option 2: Material Ingredient Optimization (1 point)
Use products that document their ingredient optimization for at least 25%, by cost, of the total value of permanently installed products
Following paths are approved:
GreenScreen v1.2 Benchmark: Products must have fully inventoried ingredients to 100ppm and show that there are no Benchmark 1 hazards
Cradle to Cradle certified (END USE PRODUCTS!) – credit that can be taken towards 25% value depends on level of certification.
REACH Optimization – ingredients must meet REACH criteria for substances of high concern
Material Ingredients

6. Option 3: Product Manufacturer Supply Chain Optimization (1pt)
Use products for at least 25%, by cost, of the total value of permanently installed products which:
Sourced from mfrs who engage in a validated, robust, safety, health, hazard & risk programs that document at least 99% of the ingredients used to make the product
Sourced from mfrs with 3rd party verification of their supply chain that at a minimum verifies processes exist
to communicate chemicals in supply chain according to hazard, exposure & use info
to identify, document and communicate H, S E characteristics of ingredients
to optimize H, S & E impacts when designing and improving ingredients
to communicate, receive & evaluate ingredient safety & stewardship in supply chain
Material Ingredients

7. Credit Area: Building Product Disclosure and Optimization - Material Ingredients
Option 1 (ingredient disclosure) is easier for product teams – that’s why you are being asked for HPDs or equivalent
Some architectural firms won’t spec your product without a material disclosure!
Options 2 (ingredient optimization) and 3 (supply chain optimization) are harder!
There are opportunities for differentiation in the optimization category….

8. 2 points maximum available Achieve one or more of 2 options
Credit Area: Building Product Disclosure and Optimization – Environmental Product Declarations
Intent
To encourage the use of products
which have life-cycle information available
that have environmentally, economically, socially preferable life-cycle impacts.
To reward project teams for selecting products from manufacturers who have verified improved environmental life cycle impacts
2 points maximum available
Achieve one or more of 2 options

9. Option 1: Environmental Product Declaration (EPD) (1 point)
Use at least 20 different permanently install products from at least 5 different manufacturers that meet one of the following:
Product Specific Declaration
Critically reviewed LCA using ISO 14044, cradle to gate minimum
¼ point per product
EPD conforming to ISO 14025, 14040, with at least cradle to gate scope
Industry-wide (generic) 3rd party verified (type III) EPD – where manufacturer was a participant - ½ point per product
Product specific Type III EPD – 1 point per product
Environmental Product Declarations

10. Option 2: Multi-attribute optimization (1 point)
Use Products that comply with one of the following for 50% by cost of the total value of permanently installed products in the project.
3rd party certified products that demonstrate impact reduction below industry average in at least 3 of the following categories
GWP, Ozone depletion, Acidification, eutrophication, tropospheric ozone, depletion of non-renewable energy resources
USGBC approved program
Products sourced within 100 miles of the project are valued at 200% of their cost
Structure and enclosure cannot constitute more than 30% of the compliant products
Environmental Product Declarations

11. Credit Area: Building Life-Cycle Impact Reduction
Intent
To encourage adaptive reuse
To encourage optimization of environmental performance of products and materials
5 Points available from 4 options:
Historic building reuse (5 points)
Renovation of abandoned or blighted building (5 points)
Building and material reuse (2-4 points)
Whole building life-cycle assessment (3 points)
Building life-cycle impact reduction

12. Option 4: Whole Building lifecycle assessment
For new construction conduct an LCA of the structure and enclosure to show a minimum 10% reduction in 3 of 6 impact categories (one must be GWP)
Service life of 60 years
Implications for the industry:
Project teams will be asking for environmental impacts (LCA/EPD information) in order to build their LCA
Building life-cycle impact reduction

13. Conclusions
LEEDv4 will be the only LEED version in use by October
For products being sold into sustainably designed buildings:
Material Ingredient hazard disclosures and LCA/EPDs are becoming essential
A number of ingredient hazard declarations are possible and straightforward
although there are still disclosures that don’t follow the rules!
LCA/EPDs take significantly more effort
Industry wide EPD to share cost?
