"More than 100,000 homes have been built and certified by voluntary, builder-supported green building programs around the country since the mid-1990s," Bob Jones, vice president and secretary of NAHB and a home builder from Bloomfield Hills, Mich., said in testimony before the House Small Business Committee. "The green movement in residential construction derives much of its strength from its voluntary nature, which provides builders and developers the flexibility that is essential for incorporating the principles of sustainable design," he said.
"By the end of this year, more than half of our members will be incorporating green practices into the development, design, and construction of these new units," said Jones. "While media interest in climate change and global warming is a relatively recent occurrence, NAHB has been consistently ahead of the curve in working to develop affordable, energy-efficient and environmentally-friendly construction techniques. In 2008, we will be hosting our 10th annual National Green Building Conference in New Orleans."
NAHB is also collaborating with the International Code Council to bring uniformity to sustainable building by developing a national consensus-based residential green building standard that will be certified and accredited by the American National Standards Institute and based on the two-year-old NAHB Model Green Home Building Guidelines, Jones said.
Encompassing single and multifamily construction, remodeling, and land development, the National Green Building Standard is expected to be completed in early 2008.
"Ultimately the goal is to develop a standard that is flexible enough to adjust to the various resource and energy concerns in the varying climate zones around the country, while at the same time encourage innovation in green technology that is already dramatically shifting the market," he said.
Jones pointed out the advantages of NAHB's guidelines, unveiled in January 2005 and derived from a consensus of more than 60 industry stakeholders, including environmentalists, building product manufacturers, architects, and research consortia. There are now 24 local green building programs based on the guidelines and more than 100 are in development.
"The guidelines allow builders to make decisions that positively impact energy efficiency, resource conservation, and indoor environmental quality throughout the entire design and construction process," he said, noting that NAHB has no financial stake in the success of its green building guidelines. "Green means doing the right thing for the builder, the home owner, and most importantly, the environment."
Congress can foster private sector innovation in green construction for the millions of homes that are waiting to be built, Jones said, by keeping the market free of mandates, striving towards the greatest energy- and resource-efficient buildings available, allocating funds for providing education and training in green construction on a broader scale, and extending and expanding federal tax credits that passed as part of the Energy Policy Act of 2005.
Federal tax credits encourage the construction of new energy efficient homes, promote the use of energy-saving home improvements for existing homes, and spur new innovation that will result in even greater energy savings in the residential built environment, he said.
