Demand for “green building materials” will average 13 percent annual growth through 2015, according to a study by the Freedonia Group. A briefing paper on the study offers up some choice highlights:

• The overall demand for U.S. green building materials is projected to rise from $39 billion in 2010 to $70 billion in 2015.

• Among the other products expected to enjoy “annual double digit gains” are “water-efficient plumbing fixtures and fittings, energy-efficient lighting fixtures, gypsum and concrete that feature recycled content, and permeable pavement.”

• The green market for floor coverings — a sector that includes the Georgia-centered carpet industry — will see healthy gains, but isn’t expected to grow quite as rapidly as the demand for many other green materials, simply “because the vast majority of floor coverings (including essentially all carpeting products) are already green and therefore the penetration rate for green materials will not be able to increase significantly.”

And, in general:

Over this period, growth in green building material demand will outpace the growth of building construction expenditures as green materials continue to account for an increasing share of materials used. While the rising use of green materials will support gains, the most important driver for demand will be the expected rebound in the construction market from low 2010 levels.
