Built Green Central Washington

Green home building program

Built Green® is an environmentally-friendly, non-profit, residential building program developed in partnership with the Central Washington Home Builders Association, Washington State Department of Ecology, and other agencies in Washington State. The Central Washington Built Green® program was developed using the National Association of Home Builders National Green Building Standard™. In a continuing effort to advance the use of environmentally responsible technologies in residential construction, the National Association of Home Builders (NAHB), the International Code Council (ICC) and the NAHB Research Center initiated a process for the development of an American National Standards Institute (ANSI) standard for green home building construction practices.
