ASHRAE, the National Association of Home Builders (NAHB), and the International Code Council (ICC) have agreed to jointly develop the 2015 edition of the ICC/ASHRAE 700 National Green Building Standard. This is the third edition of the standard and the first time that ASHRAE has partnered in its development.

Representatives from across the building industry, including code officials, building owners, manufacturers, designers, and energy efficiency advocates, have come together under the leadership of the National Institute of Building Sciences to develop a new approach to meeting green construction code requirements.
