Engineered Wood Construction Guide

Engineered wood products are a good choice for the environment. They are
manufactured for years of trouble-free, dependable use. They help reduce waste
by decreasing disposal costs and product damage. Wood is a renewable resource
that is easily manufactured into a variety of viable products.

A few facts about wood.

We’re growing more wood every day. Forests fully cover one-third of the

United States’ and one-half of Canada’s land mass. American landowners
plant more than two billion trees every year. In addition, millions of trees seed
naturally. The forest products industry, which comprises about 15 percent of
forestland ownership, is responsible for 41 percent of replanted forest acreage.
That works out to more than one billion trees a year, or about three million trees planted every
day. This high rate of replanting accounts for the fact that each year, 27 percent more timber is
grown than is harvested. Canada’s replanting record shows a fourfold increase in the number of
trees planted between 1975 and 1990.

Life Cycle Assessment shows wood is the greenest building product.

A 2004 Consortium for Research on Renewable Industrial Materials
(CORRIM) study gave scientific validation to the strength of wood as a
green building product. In examining building products’ life cycles – from
extraction of the raw material to demolition of the building at the end of its

long lifespan – CORRIM found that wood was better for the environment than steel or concrete
in terms of embodied energy, global warming potential, air emissions, water emissions and solid
waste production. For the complete details of the report, visit www.CORRIM.org.

Manufacturing wood is energy efficient.

Wood products made up 47 percent of all
industrial raw materials manufactured in the
United States, yet consumed only 4 percent of the
energy needed to manufacture all industrial raw
materials, according to a 1987 study.

Good news for a healthy planet. For every ton of wood grown, a young forest

produces 1.07 tons of oxygen and absorbs 1.47 tons of carbon dioxide.

Wood: It’s the natural choice for the environment, for design and for strong,
lasting construction.
