A5.405.2 Bio-Based Materials

Select bio-based building materials and products made from solid wood, engineered wood, bamboo, wool, cotton, cork, straw, natural fibers, products made from crops (soy-based, corn-based) and other bio-based materials with at least 50-percent bio-based content.

Certified wood is an important component of green building strategies and the California Building Standards Commission will continue to develop a standard through the next code cycle.

Use materials made from plants harvested within a ten-year cycle for at least 2.5 percent of total materials value, based on estimated cost.
