Forestry Facts
• Wood is renewable and sustainable
Source: APA
Wood is Good for the
environment
US Raw Material Production and Total Energy Used
Source: APA
A growing forest produces 1 ton of oxygen and
absorbs 1.4 tons of carbon for every ton of wood
Mature trees slow in their absorption rate of CO2
Nature is Air’s Purifier!
Harvesting insures that the carbon is locked in the
wood (Carbon Sequestration) .
Decaying trees release stored carbon back into the
atmosphere
New trees with rapid absorption rates can be
replanted to continue this air purification.

accelerates global adoption of sustainable green building
USGBC and LEED™ for Homes
accelerates global adoption of sustainable green building
and development practices through the creation and
implementation of universally understood and accepted
tools and performance criteria.”

Energy and Atmosphere (EA)
No points are specifically awarded for energy efficient use of wood
products in this section, but reducing framing materials by using
Optimum Value Engineering (OVE) and Advanced framing
techniques provides the opportunity for more insulation, thereby
allowing a builder to qualify for points in this section.
LEED™ for Homes Points with
Engineered Wood
allowing a builder to qualify for points in this section.
EA1: Optimize Energy Performance: maximum 34 points
EA 1.1- Prerequisite is to meet the performance of ENERGY STAR
for Homes
EA 1.2- Exceed the performance of ENERGY STAR for Homes.
Maximum 34 points depending on performance.
Synergies and Trade-Offs: pg 57. Reduced framing (MR1) can
allow for more insulation and fewer thermal breaks.
LEED for Homes Rating System January 2008
Energy and Atmosphere (EA) Cont.
EA2: Insulation: maximum 2 points
EA 2.1 (Basic Insulation) and EA 2.2 (Enhanced Insulation) - Use
products in an OVE/Advanced Framing system to increase
insulation opportunities.
LEED™ for Homes Points with
Engineered Wood
Synergies and Trade-Offs: MR 1.2-1.5 addresses framing efficiency.
Efficient framing can create additional spacing in wall cavities,
reducing thermal breaks and insulation compaction.
Pg 60- ENERGY STAR Inspection checklist: “Minimize thermal
bridging (e.g. OVE framing, SIPS, ICF’s)” is mentioned here.
Materials and Resources (MR)
Green building standards today recommend higher strength
framing members at wider spacings to increase the opportunities
for insulation. Wider spacings require products with wider flanges
and surface areas to maintain proper performance. Engineered
Wood wide flange I joists with 3 ½” wide flanges and wide profile
LEED™ for Homes Points with
Engineered Wood
Wood wide flange I joists with 3 ½” wide flanges and wide profile
wall studs (1-3/4” face width instead of 1-1/2”) are ideally suited
to meet the standards outlined on the following slides, providing
greater support for sheathing and drywall to maintain straight, flat
floors, ceilings, roofs and walls.
MR 1: Material-Efficient Framing: Maximum 5 points
Utilize software to create detailed framing plans, size headers
for actual loads (Optimum Value Engineering), and to produce job
specific optimized cut lists, thereby minimizing on-site waste.
MR 1.1: Prerequisite is to limit waste factor to less than 10%.
MR 1.2: Detailed Framing Documents (1 point)
LEED™ for Homes Points with
Engineered Wood

Forest Stewardship Council is an independent, non-
governmental, not for profit organization established to
promote the responsible management of the world’s
forests.
Products carrying the FSC label are independently
What is the FSC?
Products carrying the FSC label are independently
certified to assure consumers that they come from
forests that are managed to meet the social, economic
and ecological needs of present and future generations.
www.fsc.orgwww.fsc.org
Forests provide us with clean water, fresh air and
they even help combat global warming. They also
provide food, medicine and important natural
resources, such as timber and paper. If managed
responsibly, forests and plantations benefit forest
Why is the FSC Important?
responsibly, forests and plantations benefit forest
people and the global community. However, in
some countries as much as 80% of the timber is
harvested illegally. This often involves violation of
human rights and destruction of protected
forests.
www.fsc.orgwww.fsc.org
Only FSC
Prohibits conversion of natural forests or other habitat
around the world
Prohibits the use of highly hazardous pesticides around
the world
What Does the FSC Ensure?

Prohibits the cultivation of genetically modified trees
(gmos)
Respects the right of indigenous peoples around the
world
Controls each certified operation at least once a year –
and if they are found not to comply, the certificate is

  • 26. Energy and Atmosphere (EA) No points are specifically awarded for energy efficient use of wood products in this section, but reducing framing materials by using Optimum Value Engineering (OVE) and Advanced framing techniques provides the opportunity for more insulation, thereby allowing a builder to qualify for points in this section. LEED™ for Homes Points with Engineered Wood allowing a builder to qualify for points in this section. EA1: Optimize Energy Performance: maximum 34 points EA 1.1- Prerequisite is to meet the performance of ENERGY STAR for Homes EA 1.2- Exceed the performance of ENERGY STAR for Homes. Maximum 34 points depending on performance. Synergies and Trade-Offs: pg 57. Reduced framing (MR1) can allow for more insulation and fewer thermal breaks. LEED for Homes Rating System January 2008
  • 27. Energy and Atmosphere (EA) Cont. EA2: Insulation: maximum 2 points EA 2.1 (Basic Insulation) and EA 2.2 (Enhanced Insulation) - Use products in an OVE/Advanced Framing system to increase insulation opportunities. LEED™ for Homes Points with Engineered Wood Synergies and Trade-Offs: MR 1.2-1.5 addresses framing efficiency. Efficient framing can create additional spacing in wall cavities, reducing thermal breaks and insulation compaction. Pg 60- ENERGY STAR Inspection checklist: “Minimize thermal bridging (e.g. OVE framing, SIPS, ICF’s)” is mentioned here.
  • 28. Materials and Resources (MR) Green building standards today recommend higher strength framing members at wider spacings to increase the opportunities for insulation. Wider spacings require products with wider flanges and surface areas to maintain proper performance. Engineered Wood wide flange I joists with 3 ½” wide flanges and wide profile LEED™ for Homes Points with Engineered Wood Wood wide flange I joists with 3 ½” wide flanges and wide profile wall studs (1-3/4” face width instead of 1-1/2”) are ideally suited to meet the standards outlined on the following slides, providing greater support for sheathing and drywall to maintain straight, flat floors, ceilings, roofs and walls.
  • 29. MR 1: Material-Efficient Framing: Maximum 5 points Utilize software to create detailed framing plans, size headers for actual loads (Optimum Value Engineering), and to produce job specific optimized cut lists, thereby minimizing on-site waste. MR 1.1: Prerequisite is to limit waste factor to less than 10%. MR 1.2: Detailed Framing Documents (1 point) LEED™ for Homes Points with Engineered Wood MR 1.2: Detailed Framing Documents (1 point) MR 1.3: Detailed Cut list and Lumber order (1 point) MR 1.4: Framing Efficiencies (max 3 points total from any of the following): Precut framing packages (1 point) Stud spacing greater than 16” oc (1 point) Ceiling joist spacing greater than 16” oc (.5 point) Floor joist spacing greater than 16” oc (.5 point) Roof rafter spacing greater than 16” oc (.5 point) Size headers for actual loads (Optimum Value Engineering) e1

Products carrying the FSC label are independently certified to assure consumers that they come from forests that are managed to meet the social, economic and ecological needs of present and future generations. www.fsc.orgwww.fsc.org
  • 34. Forests provide us with clean water, fresh air and they even help combat global warming. They also provide food, medicine and important natural resources, such as timber and paper. If managed responsibly, forests and plantations benefit forest Why is the FSC Important? responsibly, forests and plantations benefit forest people and the global community. However, in some countries as much as 80% of the timber is harvested illegally. This often involves violation of human rights and destruction of protected forests. www.fsc.orgwww.fsc.org
