In Depth Credit Overview

22.06.2015 9

EPD Credit Intent

Encourage the use of products and

materials for which verified life-cycle

information is available

Materials and Resources

Building product disclosure and optimization – Environmental Product

Declarations (EPDs)

Encourage the selection of

environmentally-preferable products

22.06.2015 10

EPD Credit Language: Option 1

Option 1. Environmental Product Declaration (1 point)

Use at least 20 different permanently installed products sourced from at

least five different manufacturers that have:

• Product-specific LCA

(counts as ¼ product)

• Industry-average EPD

(counts as ½ product)

• Product-specific EPD

(counts as 1 product)

22.06.2015 11











Publicly available LCA report. Requires

critical review by a third party to ensure

conformance with ISO 14044.

22.06.2015 12











Type III EPD that is generic to a product

(rather than specific to a particular

manufacturer or company). For the product

to be eligible, the manufacturer must claim

representation either directly on the EPD or

through a Program Operator. Verified

through a Program Operator against ISO

14025.

22.06.2015 13











Type III EPD that is specific to a particular

manufacturer and does not necessarily

reflect the practices of the rest of the

industry. Verified through the Program

Operator against ISO 14025.

22.06.2015 14

Raw Material Credit Intent

Encourage the use of responsibly

sourced and extracted materials

through reporting and demonstration

of responsible extraction practices.

Encourage reduced use of raw

materials by selecting reused and

recycled materials.

Building product disclosure and optimization – sourcing of raw materials

22.06.2015 15

Raw Material Credit : Step-by-Step Guidance

Option 1. Raw Material Source

and Extraction Reporting (1 point)

Option 2. Leadership

Extraction Practices (1 point)

22.06.2015 16

Option 1. Raw Material Source and

Extraction Reporting

Specify and select compliant products

Specify products from manufacturers that can provide reports of raw materials

from their suppliers.

22.06.2015 17

Option 1. Raw Material Source and

Extraction Reporting

To meet the credit requirements, reports must include information on the

following:

Raw material supplier extraction locations

Commitment to long-term ecologically

responsible land use

Commitment to reducing environmental harms

from extraction and manufacturing processes

Commitment to meeting voluntary standards or

programs that address responsible sourcing

Raw Material Option 1. Documentation

22.06.2015 18

Corporate sustainability reports

• Third-party verified reports (also called externally

assured reports) are counted at full value for

credit compliance

• Self-declared reports are counted at half value.

Raw Material Option 2. Leadership Extraction Practices

For 25% of permanently installed products, by cost, use products that meet at

least one of the following responsible extraction criteria:

Location Valuation Factor

Location Valuation Factor

[formerly MR Credit Regional Materials]

• Double value for materials sourced within 100 miles of the project site

• Structural and enclosure materials – not more than 30% of the value

of compliant building products

Changes from LEED 2009

• The 500-mile (805-km) radius requirement was decreased to 100

miles (160 km)

• All extraction, manufacture, and purchase (including distribution) of

the product and its materials must occur within that radius

22.06.2015 21

Material Ingredients Credit Intent

Encourage the use of products and

materials for which the chemical

ingredients have been inventoried

Materials and Resources

Building product disclosure and optimization – material ingredients

Minimize the use and generation of

harmful substances

Reward raw material manufacturers

whose products have ‘improved’ life

cycle impacts

22.06.2015 22

Material Ingredients Credit Overview

• Option 1 – Material Ingredient Reporting

• Option 2 – Material Ingredient Optimization

• Option 3 – Supply Chain Optimization

22.06.2015 23

Option 1 – Material Ingredient Reporting

• Manufacturer Inventory

• Health Product Declaration

• Cradle to Cradle

“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).”

22.06.2015 24


“A method for comparative Chemical Hazard

Assessment that can be used for identifying

chemicals of high concern and safer alternatives”

Benchmark 1: Avoid – chemical of high concern

Benchmark 2: Use but search for safer substitutes

Benchmark 3: Use but still opportunity for improvement

Benchmark 4: Prefer – safer chemical

Manufacturer Inventory. The manufacturer has published complete

content inventory for the product following these guidelines:

• A publicly available inventory of all ingredients identified by name and

Chemical Abstract Service Registration Number (CASRN)

• Materials defined as trade secret or intellectual property may withhold the

name and/or CASRN but must disclose role, amount and GreenScreen

benchmark, as defined in GreenScreen v1.2.

22.06.2015 25


GreenScreen® List Translator

• Chemicals are mapped according

to hazard lists

• Only reports Benchmark 1 (LT-1),

possible Benchmark 1 (LT-P1),

and unspecified (LT-U)

• Assesses parent chemical only

Full GreenScreen® Assessment

• Chemicals are mapped according to

hazard lists

• Research is conducted to classify

hazard endpoints and fill data gaps

• Reports all Benchmark results

• Assesses parent chemical and

transformation products

Manufacturer Inventory. The manufacturer has published complete

content inventory for the product following these guidelines:

• A publicly available inventory of all ingredients identified by name and

Chemical Abstract Service Registration Number (CASRN)

• Materials defined as trade secret or intellectual property may withhold the

name and/or CASRN but must disclose role, amount and GreenScreen

benchmark, as defined in GreenScreen v1.2.

22.06.2015 26


HPDs are an inventory tool for reporting

potential hazards in products

Disclosure requirements

• All intentional ingredients (100%)

• All residual ingredients at 0.1% (1000 ppm)

or better

• Hazards linked to each ingredient are

automatically reported in the HPD

• ‘Full Disclosure of Known Hazards’ – the

identity of proprietary materials can be

hidden but their associated hazard must be

reported (by entering a valid CAS number)

22.06.2015 27


HPD cons

• Many chemicals and materials don’t

have CAS numbers

• No consideration of risk or exposure,

only potential hazard

Architects are asking for HPDs

22.06.2015 28


Cradle to Cradle is a multi-attribute

certification for materials,

subassemblies, and finished products

Five categories are evaluated:

“The end use product has been certified at the Cradle to Cradle v2

Basic level or Cradle to Cradle v3 Bronze level.”

An independent organization is responsible for product assessments

Certification also requires continuous improvement

22.06.2015 29

Option 2 – Material Ingredient Optimization

• Inventory with no GreenScreen benchmark 1

hazards

– Inventory of chemical ingredients to 100 ppm

– Full GreenScreen Assessment is worth more than

use of the GreenScreen List Translator

• C2C Silver, Gold, Platinum

• For international projects: no REACH substances

of very high concern

“Use products that document their material ingredient optimization using the

paths below for at least 25%, by cost, of the total value of permanently

installed products in the project.”

22.06.2015 30

Option 3 – Supply Chain Optimization

• …who have validated safety,

health, hazard, and risk

programs

AND

• …who have verification of

their supply chain processes

– Identify, optimize, and

communicate chemical effects

on health, safety, and

environmental impacts

“Use building products for at least 25%, by cost, of the total value of

permanently installed products in the project that are sourced from product

manufacturers…”
