As builders and remodelers retool their businesses in a tight credit market and recapture the interest of jittery consumers, this spring is the greenest yet for the nation's home building industry, according to the National Association of Home Builders (NAHB).  More than 3,100 builders, remodelers, designers and others in the home building business have earned the Certified Green Professional educational designation.

More than 200 single-family homes, remodeling projects and developments in 43 states have received National Green Building Certification, with another 300-plus scheduled for inspections
