LEEDing to Maximum Points With Wood: Maximizing Green Building Credits• Wood use in LEED certified buildings• Wood-related credits within the various LEED

programs.• Combining LEED credits in a single product.• Proposed LEED changes that may increase

credits for wood use.• Comparing wood points in LEED and the GBI

Program.• Summary

The Wood Products Council via the Canadian Wood Council and the Wood Solutions Fair is a Registered Provider with The American Institute of Architects Continuing Education Systems. Credit earned on completion of this program will be reported to CES Records for AIA members. Certificates of Completion for non-AIA members are available on request.

This program is registered with the AIA/CES for continuing professional education. As such, it does not include content that may be deemed or construed to be an approval or endorsement by the AIA of any material of construction or any method or manner of handling, using, distributing, or dealing in any material or product. Questions related to specific materials, methods, and services will be addressed at the conclusion of this presentation.

Program Education Credit Information

Learning Objectives� Understand wood-related credits in

the various LEED programs. � Understand the possibility of

combining LEED credits in a single product.

* Excludes mechanical, electrical, and plumbing components.

Recycled Content MRc 4

Recycled Content MRc 4

• The total value of materials* in a project is 10% recycled content. (Post-industrial recycled content is worth only one-half as much as post-consumer recycled content for this credit). (1 point)

• The total value has 20% recycled content. (2 points)

* The recycled content of a material assembly is determined by weight. Therecycled fraction of the assembly is then multiplied by the cost of theassembly to determine the recycled content value.

From sawmill or lumber planing mill

To particleboard mill.

Virtually 100% of standard particleboard is made of post industrial recycled material.

Virtually all hardboard and MDF is made of either post-industrial recycled

or post-consumer recovered fiber.

Fingerjointed studs often provide another source of recycled content material.

Optimization of Energy PerformanceWhen embodied energy differences between wood and other forms of construction are determined and spread across the life of a structure, the difference is commonly 2-4%in total annual energy consumption.

The more energy efficient a building is, the more significant differences in embodied energy become.

Low emitting composites, paints, and adhesives

Duro-design•LEED® MR Credit 7: Certified Wood

•LEED® EQ Credit 4: Low-Emitting Materials

For example, one manufacturer of wood cabinets advertises that its products qualify for 7 LEED points:

IEQc 4.1 Low emitting materials adhesives and sealants

IEQc 4.2 Low emitting materials paints and coatingsIEQc 4.4 Low emitting materials composite wood and

agrifiber productsMRc 5.2 Regional materials (2 pts.)MRc 6.0 Rapidly renewable (if bamboo or lyptus)MRc 7.0 Certified wood

Another company is advertising flooring products featuring bamboo face veneers and

formaldehyde-free hardwood plywood technology, meaning that its products qualify

for MRc 6 and IEQ 4.4 at a minimum.

Life-Cycle Assessment (LCA) of Building Assemblies and Materials

The LCA calculator determines life cycle impacts of the selected design and compares them to the average and low impact options.

Based on differences between impacts associated with the selected design and the average and lowest impact, points are awarded.
