• Survey Says: Dealers Are Slowly Getting Greener, but Skepticism Persists

  In March 2009, PROSALES magazine conducted an online survey of LBM dealers, distributors, and manufacturers regarding the state of the green construction movement in their communities as well as whether they had taken action to green their own operations. The Survey indicates dealers are getting more active in green issues, even though a significant number say there’s little demand to do so. A small majority of dealers responding to the nationwide, online poll said they’re getting asked more often these days about green, but 41% still categorize interest in their area as nonexistent or barely there.

Green by Design: Renewable, Durable, Sustainable Wood

The ATHENA™ Sustainable Materials Institute’s ultimate goal is to encourage the selection of material mixes that will minimize the environmental impact of a building over its life-cycle. The ATHENA computer model was used to compare alternative wood, steel and concrete structural designs for a three-story office building. The ATHENA findings are the result of a five-year research program involving architects, environmentalists, economists, engineers, and representatives from the steel, concrete and wood industries. ATHENA™’s life-cycle research found that wood building products have the lowest environmental impact when compared to other major building materials, based on raw materials and energy use, emissions to air, water and land.

What are the facts?

• Total energy use: The wood building used the least energy. The concrete option required 1.7 times the energy for wood. The steel option required 2.4 times the energy. Wood simply does not require much energy to manufacture.
• Greenhouse gases: The wood building had the lowest greenhouse gas emissions. The steel building generated 1.45 times and the concrete building generated 1.81 times the greenhouse gases for wood.
• Air pollution: The wood design had the lowest air pollution index. The steel building produced 1.42 times and the concrete building produced 1.67 times the air pollution index.
• Solid waste: The wood design had the lowest solid waste. This takes into account both manufacturing and on-site construction waste. Steel produced 1.36 times and the concrete produced 1.96 times the solid waste. This means there is virtually no waste during the manufacturing process and the use of engineered wood products has radically reduced the on-site construction waste.
• Ecological Resource Use: The wood design had the lowest ecological resource use index. Steel was 1.16 times and concrete was 1.97 times the index for wood. This factor compares the long-term effects of resource extraction. Although forestry affects a large area, reforestation means the effects are short term. Sustainable forest management practices help ensure that disruption is minimized.
• Conclusion: The office building built with wood had lower environmental impact for energy use, greenhouse gases, air and water pollution and ecological resource extraction than the steel or concrete building. A similar case study of residential buildings (comparing wood, steel and concrete construction) produced similar findings in terms of wood’s superior environmental performance.

These facts and others based on the ATHENA life-cycle findings can be found in a new primer put out by the Canadian Wood Council & the Forest Products Association of Canada have put out a primer, “Green by Design”.

“Green By Design: Renewable, Durable, Sustainable Wood.” Canadian Wood Council & Forest Products Association of Canada. (CWC & FPAC)

A primer on the environmental comparisons of wood and other materials in home and building construction.

This brochure explains why asking for Canadian wood products is the best environmental choice. It shows how taking a life cycle approach to building design will result in wood being the winner over competing products such as steel and concrete.

Addressing Negative Perceptions and Campaigns

According to the Wood Promotion Network, the last five years have witnessed mounting efforts by competing industries and environmental groups to reduce the market for wood. Their recent studies show that between 1997 and 2000 lumber alone lost 2.5% of the residential market for floors, walls and roofs. Significant environmental campaigns have been aimed at putting pressure on major corporate buyers of wood products. As a result, the public has been led to believe that forest are diminishing, that industry practices are not sustainable, and that the world needs to use less rather than more wood.

The Wood Promotion Network is N. America’s largest ever coalition of wood product and allied industry companies and related associations, representing more than two-thirds of N. American wood production. These companies have joined together to educate builders, DIYers and homeowners throughout North America on the benefits of wood building materials and the abundance of today’s North American forests.

Thus, the WPN goals are to secure and expand wood markets in N. America and to increase confidence about forest abundance and sustainability. While the goals may seem ambitious, the hard facts show that wood is the best environmental choice, hence it is not surprising that their campaigns to date have resulted in major achievements in terms of improving building and consumer perceptions of wood.

What are some of the messages that the Wood Promotion Network gets across:

• N.America’s forests are abundant and growing, based on satellite imagery.
• Wood is the best insulator against heat and cold, which makes it the most energy efficient material that can help keep home energy bills in check.
• Regardless of market volatility, wood is the most affordable building material you can use. Framing an average 3-bedroom home can cost up to 30% less with wood versus other framing materials.
• New innovations in engineered wood products and pre-made panels and trusses help builders and homeowners keep framing costs down. (WPN AR2001).
• The production and use of wood is easier on the environment than any other building material. It takes less non-renewable fossil fuels and less energy to produce wood framing materials than alternative framing materials. (WPN AR2001).
• Wood is the world’s only 100% renewable building material and is manufactured with the organic power of solar energy. (WPN AR2001).
• Wood is the only major building material that is renewable. Canada’s sustainably managed forests ensure that there is an ample supply. New manufacturing technology allows every part of the tree to be used so that nothing is wasted. Advanced engineered wood products make use of fast growing species to produce high strength products without requiring large dimension timbers to meet building needs. (WPN AR2001).

Build with Wood and Help Protect the Environment

Over 80% of Canadians believe that sustaining the environment is a major priority. Many of us do our part, by recycling newspapers, refusing or reusing shopping bags, and composting waste.

But we may not realize that we make a much bigger impact on the environment through our choice of building materials.

Due to sustainable forestry practices, the volume of wood in Canada’s productive forests increased by 35% between 1976 to 1991. Last year alone, over 700 million seedlings were planted. That’s about 25 trees planted for each Canadian.

But how do we replace the thousands of tons of ore that went into steel beams or aluminum siding, or the millions of litres of petroleum that went into making plastic components?

The answer is – we can’t. Those resources are finite. Once we consume them, they are gone forever.

A study by the Canadian Research Alliance examined the relative environmental impacts of various building materials. The results clearly demonstrate not only that wood is a renewable resource, but also that the manufacture of wood products is cleaner, less wasteful, and consumes less energy than the alternatives.

Life-cycle analysis shows that a steel wall requires 3 to 6 times more energy to extract, manufacture and construct than a wood wall. The steel wall also uses 25 times more water in its manufacture, and releases 3 to 6 times more carbon dioxide emissions.

The manufacture of concrete produces 2 to 3 times more carbon dioxide than wood, and results in 5 times more solid waste.

The production of aluminum generates 8 times more polluting emissions in the air and 300 times more in the water, than the manufacture of wood. The manufacture of aluminum siding requires 5 times more energy than wood.

Construction is a $25 billion a year industry in Canada. That’s the equivalent of almost $900 for each Canadian, much of it spent on building materials.

Selecting Environmentally Friendly Flooring

Thinking of replacing that worn flooring in the front hallway?

By shopping around, you can get information about the price, style, and maintenance of commonly-used flooring products.

It is much harder to learn about the hidden impact of these products on the environment. To make an informed choice, consumers also want to know about the composition and manufacture of various flooring materials.

Synthetic sheet flooring, such as cushion flooring, is made from non-renewable petroleum resources. Because it is non-biodegradable, scraps cannot be recycled. The manufacturing process is energy-intensive, depleting the supply of fossil fuels.

Ceramic tiles are made by firing clay, a plentiful resource. However, the kilns used to fire the clay consume large quantities of energy. Ceramic tiles are not recyclable.

Linoleum is made with renewable ingredients (linseed oil, cork, wood dust and dyes) that have been heat-cured and sealed, but it is not recyclable. Various chemicals are used for manufacturing, although less than are required for synthetic floor materials.

So what can you select that is environmentally friendly as well as being durable, easy-to-care-for, beautiful and affordable?

The answer is wood. Oak and maple hardwood flooring – solid plank, pre-finished wood flooring systems, parquet tiles and veneer – comes from wood, a renewable resource. Part of the energy used in the manufacturing process comes from wood waste materials.

Veneer flooring is comprised of a surface of high quality hardwood laminated to a plywood or particle board backing, and packaged as tiles. Wood fibre waste from low grade wood is used in the backing, and high-grade wood is used in the surface veneer.

When you’re shopping around, ask your retailer or contractor for more information from the flooring manufacturer. That way you can select a product that is attractive to the environment AND to your home.

Build that New Fence with Wood and Help Protect the Environment

When you shop for materials to build your new fence or deck, you probably think about things like appearance, ease of installation, and cost. But what about the cost to the environment of the building materials that we buy?

Over 80% of Canadians believe that sustaining the environment is a major priority. Many of us do our part by recycling newspapers, adding extra insulation in our homes, and walking to the video store at the corner instead of driving. But we also make a major impact on the environment when we choose building materials, often without realizing it.

Wood is a popular and attractive choice for many outdoor landscaping projects. Due to sustainable forestry practices, the volume of wood in Canada’s productive forests increased by 35% over the last 20 years. Last year alone, about 700 million seedlings were planted. That’s over 20 trees planted for each Canadian.

But what about that chain-link fence, those concrete patios stones or that vinyl lounge chair? How do we replace the thousands of tons of ore that went into the manufacture of steel, or the millions of litres of petroleum that went into making plastic components?

The answer is – we can’t. Those resources are finite. Once we consume them, they are gone forever. And the manufacturing process has added to the world’s pollution problems.

A study by the Canadian Research Alliance examined the relative environmental impacts of various building materials. The results clearly demonstrate that the manufacture of wood products is cleaner, less wasteful, and consumes less energy than the alternatives.

Life-cycle analysis shows that a steel wall requires 3 to 6 times more energy to extract, manufacture and construct than a wood wall. The steel wall also uses 25 times more water in its manufacture, and releases 3 to 6 times more carbon dioxide emissions.

The manufacture of concrete produces 2 to 3 times more carbon dioxide than wood, and results in 5 times more solid waste.

The production of aluminum generates 8 times more polluting emissions in the air and 300 times more in the water, than the manufacture of lumber. The manufacture of aluminum siding requires 5 times more energy than lumber.

So when you go to buy the materials for that new fence or deck, consider the alternatives – and make an informed choice.

Size
About half of Canada’s land mass is covered by forest, that is approximately 417 million hectares. Only ¼ of Canada’s forests are dedicated to forest management (119 million hectares), the remainder, for example, is either protected from harvesting, is of a non-commercial quality, or is commercial but not yet accessed or allocated.

Ownership
94% percent of Canada’s forests are publicly owned, while the remaining 6% is private property belonging to more than 425,000 landowners.

Harvest Levels
Canada harvests less than ½ of 1% of its commercial forest area each year, or ¼ of 1% of its total forest area. Moreover, it grows twice as much timber as it harvests. About ½ of the Canadian forest will NEVER be harvested. That never-to-be-logged Canadian forest is larger than California, Arizona, New Mexico, Texas and Louisiana combined.

Fire, Insects & Disease
Did you know that Canada harvests less of its commercial forest each year (0.4%) than is taken by fire, insects and disease (0.5%).

Regeneration
By law all forests harvested on Canada’s public lands must be replaced. . More than half of the area harvested in Canada is left to regenerate naturally. Many tree species can reestablish themselves on a site without planting or seeding. These natural mechanisms include seeding from the adjacent forest, suckering of stumps and roots, and growth of young trees remaining on the harvested area. In summary, regeneration is accomplished by natural regeneration (53%), planting (43%), and aerial seeding (4%).
An Abundant and Growing Forest
The area of trees growing in Canada is growing not shrinking. In fact, during the 5 year period, 1990-1995, the United Nations FAO estimated a net increase of 4% in the area of trees growing in Canada’s commercial forests.
Helping Our Climate
Trees are living plants that ‘breathe’ to help them grow. As they breathe, they remove unwanted carbon dioxide from the air – a greenhouse gas that contributes to global warming – and replace it with life sustaining oxygen.
Park System
Canada is the world leader in terms of area dedicated to its national and provincial park system for the use and enjoyment of Canadians and citizens around the world. Its national and provincial parks alone occupy some 56.8 million hectares. Compare that to the area of forests managed primarily for wood production in Canada – 119 million hectares – and one can quickly see that Canada’s forests are maintained for a variety of values and uses.
Original Forest Cover
Almost half of the Earth’s original forest cover is gone, much of it destroyed within the past three decades. In contrast, Canada has maintained over 90% of its forest cover and it has done so while being one of the world’s largest producers of high-quality forest products.
Forest Certification
Certification provides proof that forests are being managed by an independent 3rd party audit. Currently, if including CSA, SFI, FSC and ISO 14001 certifications, Canada has certifications covering some 115 million hectares of forest land- the largest certified forest area in the world! If however, one considers only those certifications to forestry-specific standards such as CSA, SFI, FSC, Canada has over 25 million hectares of forest land certified – of which 1 million is certified to FSC (see next bullet). However, the area of certifications to forestry-specific standards (CSA, SFI, FSC) is scheduled to grow considerably by 2006 given a new commitment by the Board of FPAC. It is also important to remember that the vast majority of wood coming from Canada’s forests are well-managed, certified or not. For more information on the forestry specific standards noted above or on forest management certification status in Canada, visit www.CertificationCanada.org.

FSC Forest Certification
Forest Stewardship Council (FSC) certification is not practical for small 10-100 acre parcels of land which are the primary source of high value hardwood in Canada. Costs to implement and maintain an FSC certification would be higher than the value of product derived. To be brief, FSC on small private lands managed for timber is conceptually unworkable in Canada. This point is made given that many environmental organizations lobby purchasers of Canadian forest products to specify FSC certified wood – this is an unrealistic demand for most small private woodlots in Canada. It should also be noted that even large scale commercial forestry operations in Canada for the most part are not pursuing FSC certifications for a variety of reasons. To date, 1 million of 25 million hectares of certified forest land in Canada is certified to the FSC Principles.

With 100% financing from the Bank of America, a nonprofit conservation group has purchased 50,000 acres of redwood forest along the Mendocino County coast north of Fort Bragg for $65 million and plans to use it for commercial timber harvesting while shielding the land from development.

“We know that this property without protection would have been subdivided into smaller parcels,” Art Harwood, a sawmill operator and president of the Redwood Forest Foundation, told reporters Thursday in the redwood grove outside the Transamerica Pyramid in San Francisco. “Every year in the U.S., millions of acres of forest are bought and sold, and the pressure is particularly high in Northern California.”

Bank and foundation officials said the deal is the first of its kind that relies entirely on private financing.

However, much of the debt is to be paid through the sale of a conservation easement to another nonprofit group that plans to seek state funding.

Harwood said the land, acquired from Hawthorne Timber Co., was heavily logged in the 1980s and ’90s and now consists primarily of second-growth redwood and Douglas fir. “There are a few old-growth trees scattered out there, but we will not be cutting them,” he said.

Foundation officials said they plan to do very little logging at first, and never on more than 3% of the property a year to ensure a long-term supply of jobs and timber. The Redwood Forest Foundation, which is dedicated to restoring working forests, plans to use logging revenue to help pay off the 20-year loan.

The foundation, based in the southern Mendocino County town of Gualala, intends to sell the conservation easement to the Conservation Fund, which plans to use state money approved by voters last year in Proposition 84, the clean water, parks and coastal bond measure.

“We haven’t negotiated the cost of the easement and the terms,” said Chris Kelly, who manages California operations for the fund. “But our intention is to have an agreement allowing no subdivision, development or conversion to non-forest uses, and possibly there will be a cap on harvesting.”

The land is north of Fort Bragg and about 50 miles north of two other parcels purchased recently by the Conservation Fund.
