•  The movement toward net-zero buildings needs continued impetus from federal tax breaks that offset higher costs rather than letting them expire this year and next.
• Greenbuildingelements.com says the support is needed for "a few more years" to get green construction to maturity.
• More growth in the trend will reduce the up-front cost of materials, and the projects will make economic sense without figuring in tax advantages.

From the article:

Tax breaks passed by the U.S. government to encourage construction of green buildings are set to expire in 2012 and 2013. The key to ensuring long-term adoption of solar energy and eco-friendly construction materials, in the eyes of many industry professionals, is to extend these tax breaks for a few more years in order to continue reducing up-front investment costs.
