The new 37,000-square-foot Kendeda Building for Innovative Sustainable Design is seeking LEED Platinum and Living Building Challenge certification. 

The creator of the Rigorous Living Building Challenge designs his own super-sustainable dwelling.

California, Oregon and Washington are among the states moving forward with regulations and road maps for the construction and operation of building- and district-scale graywater capture and treatment systems for non-potable-water use, such as toilet flushing and irrigation.

Forward-thinking project teams regard water as a precious resource.

Earlier this month, the first building in the U.S. permitted to treat rainwater for potable uses also became a Living Building—the highest level of ultra-green-building certification granted by the International Living Future Institute.
