What is the

LEED Rating System?

History and Growth of LEED Leadership in Energy & Environmental Design

World-recognized 3rd party rating systems.

Distinguishes top 15% of high performance buildings.

U.S. Green Building Council (USGBC) formed in 1993.

Rating Systems adopted by the Canada Green Building Council (CaGBC) in 2001.

LEED Version 4 launched November 2013 and mandatory as of October 2016

OVERVIEW OF LEED

History and Growth of LEED Preeminent global green building program and is in use in over 140

countries

More than 3.3 billion square feet of space has been certified under LEED

Over 1.7 million SF of building space certified daily

4 Certification Levels

Why are so many

buildings certifying under the LEED program?

Study of the 30 largest markets in the U.S. found that:

At the end of 2013, commercial buildings certified by LEED represented 5.1% of the total market [up from 0.1% at the end of 2005]

Measured by floor area, LEED-certified space represented almost one-fifth (19.4%) of the total commercial office market.

BENEFITS OF GREEN OFFICES

Financial • Reduce Life-Cycle Costs • Lower Insurance Rates • Energy Risk Reduction • Reduced/Easier Churn

Productivity • Reduced Absenteeism • Recruitment Tool • Improved Employee Morale

Corporate Citizenship • International Recognition • Increased Sales and Marketability

BOTTOM LINE BENEFITS OF GREEN BUILDINGS

FINANCIAL BENEFITS OF PRODUCTIVITY INCREASE

Carnegie Mellon Studies have shown that productivity increases range from 0.4% to 18%

Average cost of a US office Building

Salaries $318.00 per SF

Technology 50.00 per SF

Lease / Mortgage 32.00 per SF

Energy 2.35 per SF

Total $402.35 per SF

Findings:

1% increase = $3.18 per SF savings

5% increase = $15.90 per SF savings

Financial • Reduce Life-Cycle Costs • Lower Insurance Rates • Energy Risk Reduction • Reduced/Easier Churn

Productivity • Reduced Absenteeism • Recruitment Tool • Improved Employee Morale

Corporate Citizenship • International Recognition • Increased Sales and Marketability

BOTTOM LINE BENEFITS OF GREEN BUILDINGS

LEED vs Non-LEED STUDY CONCLUSIONS

Buildings with a green rating (LEED or Energy Star) command rental

rates that are roughly 3 percent higher per square foot than otherwise identical buildings — controlling for the quality and the specific location of office buildings.

Premiums in effective rents are even higher — above 7 percent.

Selling prices of green buildings are higher by about 16 percent.

WHERE WE WERE

LEED Version 1 (released 2007): Credits that encourage use of forest products:

MRc5: Regional Materials (1-2 points)

MRc6: Rapidly Renewable Materials (1 point)

MRc7: Certified Wood (1 point)

EQc4.4: Low-Emitting Materials: Composite Wood and Agrifiber Products (1 point)

HOW FOREST PRODUCTS ARE RECOGNIZED IN LEED

WHERE WE ARE

LEED 2009 (released 2010):

Credits that encourage use of steel products: MRc2: Construction Waste Management (1-2 points)

MRc5: Regional Materials (1-2 points)


WHERE WE ARE GOING

LEED Version 4 (released 2013): Credits that encourage use of forest products:

MRc1: Building Lifecycle Impact Reduction – Life Cycle Assessment (3 points)

MRc2: Building Product Disclosure and Optimization: Environmental Product Declarations (1 point)

MRc3: Building Product Disclosure and Optimization: Sourcing of Raw Materials (1 point)

MRc4: Building Product Disclosure and Optimization: Material Ingredients (1 point)

EQc2: Low-Emitting Materials (1-3 points)


NEW LEED VERSION 4 CREDIT: MRc1: Building Lifecycle Impact Reduction

Credit Requirements: Whole building lifecycle assessment demonstrating 10% reduction in at least 3 out of 6 impact categories (e.g. global warming potential)

Steel Contribution:

The LCA incentivizes materials with comparatively low environmental impact.


What is an LCA? Life cycle assessment – a comprehensive analysis that provides a more complete understanding of a product’s total impact. LCAs account for all the materials, processes, and services that go into making and using a product. These also show the balance between all phases of a product’s life – from raw material acquisition through to disassembly and disposal of components.

NEW LEED VERSION 4 CREDIT: MRc2: Building Product Disclosure and Optimization: Environmental Product Declarations

Credit Requirements: Use at least 20 different permanently installed products sourced from at least five different manufacturers that meet one of the disclosure criteria: Environmental Product Declarations OR Product-Specific Declaration.

Steel Contribution:

Wood products with environmental product declarations contribute toward this credit.


What is an Environmental Product Declarations? The goal of an Environmental Product Declaration (EPD) is to provide relevant, verified and standardized information about the environmental impact of a product or system.

• Think of these as the declared unit/serving size like on a nutritional label.

EPDs are reports compiled from an LCA and developed according to the rules as defined by PCRs for the specific product.


NEW LEED VERSION 4 CREDIT: MRc3: Building Product Disclosure and Optimization: Sourcing of Raw Materials

Credit Requirements: OPTION 1: Use at least 20 different permanently installed products from at least 5 different manufacturers that have publicly released a report from their raw material suppliers.

Wood Contribution:

OPTION 1: Wood from suppliers and manufacturers with a Corporate Sustainability Report contribute.


NEW LEED VERSION 4 CREDIT: MRc3: Building Product Disclosure and Optimization: Sourcing of Raw Materials

Credit Requirements: OPTION 2: Use products that meet at least 1 of the responsible extraction criteria for at least 25%, by cost, of the total materials cost.

Wood Contribution:

OPTION 2: New wood products with the FSC or Sustainable Agriculture Network labels (or equivalent standard) contribute. Under the new pilot ACP, wood certified under programs meeting ASTM D7612-10 also count, when threshold conditions are met, such as 100% of wood must be legally harvested.


NEW LEED VERSION 4 CREDIT: MRc4: Building Product Disclosure and Optimization: Material Ingredients

Credit Requirements: OPTION 1: Material Ingredient Reporting (to at least 0.1%) OPTION 2: Material Ingredient Optimization OPTION 3: Product Manufacturer Supply Chain Optimization (robust programs and processes to ensure safety and health and reduce hazards and risks).

Steel Contribution: An EPD will help in satisfying these requirments.


NEW LEED VERSION 4 CREDIT: EQc2: Low-Emitting Materials

Credit Requirements: Flooring: Prefinished wood flooring must comply with California Department of Public Health Standard Method v1.1-2010. Composite Wood: Must meet CARB ATCM for formaldehyde requirements for ultra-low-emitting formaldehyde (ULEF) resins or no added formaldehyde (NAF) resins.

Wood Contribution: Flooring: Untreated and unfinished wood is classified as an inherently non-emitting source and can contribute.


MORE POINTS FOR REGIONAL MATERAILS: Building Product Disclosure and Optimization Credits

Wood Contribution: Triple-bottom line benefits of locally harvested, manufactured materials Purchasing locally (within 160km from project site) helps project teams meet the performance thresholds in all three of the BPDO LEED credits, helping projects earn up to three points.
