Description
Net Zero Water for Buildings and Sites is the curriculum associated with designing integrated water systems that work towards the goal of freeing a facility from the need to connect to the municipal water and wastewater system. Very few buildings around the world have accomplished this feat, yet it remains a critical component of moving towards greater resiliency, and it is a requirement under the Cascadia Green Building Council’s Living Building Challenge.
The comprehensive program adopts a net- zero approach to investigate and provide practical tools for harvesting, treating, distributing, storing, using (and reusing) water on site.
