CORRIM Study Shows Wood Use Better for Environment than Steel or Concrete Life cycle assessment gauges the energy required to produce building materials, as well as construct, maintain and demolish a typical home over its useful life. The CORRIM study concluded that the bulk of energy required to build an average home is consumed during the manufacture of building materials—not during actual construction. “Considering 1.7 million homes using wood, steel and concrete are constructed each year, choosing construction materials wisely is significant,” said study participant Bruce Lippke, Professor of Forest Resources, University of Washington. “The manufacture of these construction materials requires as much energy as heating and cooling 10 million or more homes annually.” The energy tallied for the study spanned the life cycles of the homes, including: diesel and fuel oil to extract and haul materials, natural gas to generate steam in lumber mills and electricity for steel mills, and electricity used by the homeowner. “Everything flows from energy consumption,” Lippke says. “If you’re using energy, you’re polluting water, polluting air and kicking out carbon dioxide emissions.” The study concluded that wood uses significantly less energy than concrete or steel over the 75-year life cycle. The report also offers suggestions on how to help reduce the energy demands of home construction, including: Redesigning houses to use less fossil-fuel intensive products Changing building codes that result in excessive use of materials Recycling demolition wastes Increasing durability of homes through improved products and construction practices
