Reporting from the International Builders’ Show in Las Vegas, suppliers said more consumers are seeking green products, especially those that focus on energy and water efficiency, and there is every indication that trend will only get stronger.

Representatives from Kohler Co., Marvin Windows and Doors, and Whirlpool Corp. talked about innovations that can lower homeowners’ water and energy bills and also contribute to better indoor air quality.

The National Association of Home Builders is providing education and training, as well as home certification services to help prepare homebuilders and remodelers to capitalize on this trend. NAHBGreen, the association’s green building program, is expanding every month.

Energy efficiency is still the biggest driver, manufacturers said, but demand is also growing for water-efficient fixtures and appliances, as well as windows and doors that contribute to improving indoor air quality, the speakers said.

“Consumers and builders are starting to recognize the long-term benefit of green products,” said Omer “Butch” Gaudette, director of trade relations for Whirlpool Corp. “If you’re not building green, you’re not building.”
